It also has a different ecology from + +S. arborea + +, being found at lower altitudes. + + +The habit of the species needs further field studies; two collections are recorded as “lianas” ( +Germain 249 +and +Lebrun 5674 +) and one as a shrub ( +Lotter 1486 +). The two flowering collections ( +Germain 249 +and +Lebrun 5674 +) are both of the brevistylous form; the species is likely to be heterostylous, as most species in the genus. + + +Conservation status:—IUCN Red List Category: Endangered +[ +EN B2ab(i,ii,iii,iv) +].

None of the localities are protected, and deforestation for agriculture and for mining in the eastern part of its range, represents a clear threat to the species.

The latter species differs in its entirely white corolla, and shorter and markedly discolorous calyx lobes (see +Table 4 +). + + + +Sabicea sthenula + +usually has leaves solitary at each node, opposed to the stipule of the same node; however, occasional variants with two unequal leaves and two stipules per node have been noted ( +de Foresta 976, Lejoly 96/ 680, Dessein et al. 2264 +). These variants are quite similar to + +S. medusula + +; see Key and +Table 4 +for morphological differences. +Sosef et al. 2669 +(WAG), from southern +Gabon +, is probably also one such variant, but the specimen is poor and has the leaves narrower than usual for + +S. sthenula + +. + + +A collection from south +Cameroon +, +J.

Louis et al. 2563 +(BR, WAG) show intermediate characters between + +S. medusula + +and + +S. sthenula + +. They resemble + +S. medusula + +in their short bracts and very narrow calyx lobes with stiff hairs, but have multifid stipules and leaves with 6–9 pairs of lateral veins, as in + +S. sthenula + +. Their identity is at present unclear; they may represent a new taxon. + + +Conservation status:— +IUCN Red List Category: +Least Concern [LC]. +The extent of occurrence is estimated as +258,268.920 km +2 +, and the area of occupancy as +80.000 km +2 +, the latter value being within the limit for Endangered under criterion B2. However, the species is known from more than 10 locations (including one protected area, the Dimonika Biosphere Reserve in +Congo +) (sensu +IUCN 2012 +). Most of its range is sparsely populated, and due to its preference for open habitats, the species benefits from small-scale forest clearance. It is also very likely to be more widespread than records suggest, as it is neglected by collectors due to its low size. It is therefore not threatened at present. + + + +Additional specimens examined:— +CAMEROON +. + +Central province: Mefou proposed National Park, +M. Cheek, Essama, V.

It differs from both species in the calyx lobes broadly elliptic, +/- flat, glabrous outside apart from woolly hairs on the margin. More collections from the same area are needed to decide its status. + + +Conservation status:— +IUCN Red List Category: +Vulnerable [VU B2ab(i,ii,iii,iv,v)]. +The extent of occurrence is estimated as +51,744.709 km +2 +and the area of occupancy as +72 km +2 +, the latter value being within the limit for Endangered under criterion B2. The species is known from 16 subpopulations representing 7 locations (sensu +IUCN 2012 +), including three protected areas (Lopé National Park in +Gabon +, Altos de Nsork National Park in +Equatorial Guinea +, and the Dimonika Biosphere Reserve in +Congo +). One of the locations at least (Mabounié, in +Gabon +) is potentially at risk from a mining project. A decline in the extent of occurrence, area of occupancy, extent and quality of habitat, number of locations and number of individuals can therefore be expected, and the species qualifies for Vulnerable status under the conditions B2ab (i,ii,iii,iv,v). + + +TAXONOMIC REVISION OF +SABICEA +SUBGENUS + +ANISOPHYLLAE + + + +Phytotaxa +293 (1) © 2017 Magnolia Press • +57 + + + + \ No newline at end of file diff --git a/data/03/82/87/038287FF034FD64872A5FE114533F99D.xml b/data/03/82/87/038287FF034FD64872A5FE114533F99D.xml new file mode 100644 index 00000000000..f178c92276b --- /dev/null +++ b/data/03/82/87/038287FF034FD64872A5FE114533F99D.xml @@ -0,0 +1,822 @@ + + + +Taxonomic revision of Sabicea subgenus Anisophyllae (Ixoroideae, Rubiaceae) from Tropical Africa, with four new species + + + +Author + +Zemagho, Lise A. +Plant Systematic and Ecology Laboratory, Higher Teachers´ Training College, University of Yaoundé I, P.

These characters justify its treatment as a species of its own. The ranges of the two taxa are separate, + +S. jacfelicis + +being more northern. + + + +Sabicea jacfelicis + +differs from other lianescent species with inflorescences on the old stems ( + +S. aurifodinae +, +S. crystallina +, +S. ndjoleensis + +and + +S. sciaphilantha +) + +by the shorter calyx lobes and especially by the much shorter corolla tube. + + +Notes: +— +Two specimens +from +Gabon +( +N.

Two of these locations are potentially threatened by the construction of dams (around Nyabessan in +Cameroon +, and Makokou in +Gabon +) and one by a mining project (Bélinga, +Gabon +). Therefore, a decline in the extent of occurrence, area of occupancy, extent and quality of habitat, number of locations and number of individuals can be projected, and the species qualifies as Vulnerable under conditions B1ab(i,ii,iii,iv,v) and B2ab(i,ii,iii,iv,v). + + + +FIGURE 16. +Distribution of +Sabicea jacfelicis +. + + + +Additional specimens examined:— + + +CAMEROON + +. +East Province +: +between Somalomo and Milon +, + +69 km +SE of Akonolinga + +, + +18 June 1981 + +, + +J.n. +Asonganyi +311 + +( +BR +, P, +YA +); +Station du Cacaoyer de N’Koemvone +, +14 km +on the road from Ebolowa to Ambam, + +28 August 1974 + +, + +J.J.F.E. de Wilde +7442 + +( +BR +, +WAG +) + +; + +Station du Cacaoyer de N’Koemvone +, +14 km +on the road from +Ebolowa +to +Ambam +, + +8 April 1975 + +, + +J.J.F.E. de Wilde +8155 + +( +BR +, +MO +, P, +WAG +, +YA +); Ambam, bords +du Ntem +, + +April 1940 + +, + +H.

The species is common in its main range extending from extreme south-eastern +Nigeria +to +Equatorial Guinea +, centered on +Cameroon +; an apparently isolated and very disjunct population occurs in northern +DR Congo +, on the lower Uele River ( +Fig. 18 +). + + +Habitat and ecology +:—Degraded areas in forest, usually growing in half-shade and often covering the ground on paths; also along forest streams (which are probably the original habitat) and sometimes in cocoa plantations; at +0–580 m +altitude. + + +Phenology +:—Flowers in January, April–July, September and November; fruits in February–March, May– September and November. + + + + +Discussion: +— + +Sabicea medusula + +closely resembles + +S. parmentierae + +and + +S. sthenula + +in the low habit, and the corolla with a pink tube and white lobes. Another similar species, though with an entirely white corolla, is + +S. mildbraedii + +. The differences between these four species are shown in +Table 5 +. Wernham’s description of + +S. medusula + +is based on +two syntypes +, +Zenker 2095 +and +4414 +. The latter specimen is more complete and agrees better with the description; therefore we choose the specimen Zenker 4414 as type. We have not seen the specimen indicates by +Wernham (1914) +at BM. The WU sheet of this specimen is the most complete, therefore we choose it as +lectotype +. + + +The indumentum of the calyx lobes is somewhat variable in + +S. medusula + +: the exterior varies from densely white-felted to green and nearly glabrous; the interior typically bears long stiff hairs intermingled with denser shorter ones, but sometimes only the long hairs are present. + + +The only collection of + +S. medusula + +from +DR Congo +, despite being geographically distant from the other collections, does not show any morphological differences. The specimen from +Nigeria +was seen on photograph only, but the identification is certain. We have seen no authentic material of + +S. medusula + +from either +Gabon +or the +Republic of Congo +, although the species can be expected in both countries; a previous record from the +Republic of Congo +( +Lachenaud 2009 +) refers to + +S. sthenula + +, while the Gabonese collections cited as + +S. medusula + +by +Hallé (1971) +and + +Sosef +et al. +(2006) + +belong to + +S. parmentierae + +and + +S. sthenula + +, respectively.

Because of differences between these two taxa we prefer to treat them as separate species (see +Table 2 +). + + +Notes: +— + +Sabicea bequaertii + +is not to be confused with + +S. becquetii + +, which is closely related and has a confusingly similar name. + + +Conservation status:— +IUCN Red List Category: +Vulnerable [VU B1ab(i,ii,ii,iv,v) + B2ab(i,ii,ii,iv,v)]. +The extent of occurrence is estimated as +17196,970 km +2 +and the area of occupancy as +60 km +2 +, respectively within the limits for Vulnerable and Endangered under criteria B1 and B2. The species is known from 12 subpopulations representing 7 locations (sensu +IUCN 2012 +). Most of the subpopulations occur in protected areas, Nyungwe National Park in +Rwanda +, Kahuzi-Biega N.P. in +DR Congo +, and Bwindi-Impenetrable N.P. in +Uganda +. However, in view of the high population pressure and political instability of the region, a decline in the extent of occurence, area of occupation, habitat extent and quality, number of locations and number of individuals can be expected, and the species qualifies for Vulnerable status under the conditions B1ab(i,ii,ii,iv,v) and B2ab(i,ii,ii,iv,v). + + +Additional specimens examined:— + + +DR CONGO + +. +Lwamisole +, + +15 June 1949 + +, + +F.L.

It also differs in having the leaves usually villose above (rarely glabrescent, e.g. in Bouharmont 13179) and the bracts generally larger; see +Table 2 +for a summary of morphological differences. Furthermore, it has a different geographic range, the other two species are not known from +Burundi +. + + +The habit of + +Sabicea becquetii + +seems to be quite variable according to collectors notes, and needs further field study. It is apparently not a free-standing shrub, but rather a scrambling plant, which might start as a small shrub and become sarmentose as it gets older. The seeds of + +S. becquetii + +, which have been described as smooth by +Hallé (1964) +, are in fact conspicuously reticulate ( +Fig. 6 +). + + +Conservation status:— +IUCN Red List Category: +Vulnerable [VU B1ab(i,ii,iii,iv,v) + 2ab(i,ii,iii,iv,v)]. +The extent of occurrence is estimated as +3868.579 km +2 +and the area of occupancy as +80 km +2 +, both within the limit for Endangered under criteria B1 and B2. Based on herbarium records, the species is known from 15 subpopulations (sensu +IUCN 2012 +), but 7 of them are likely to be extinct, and others are threatened. Only two populations are present in protected areas, namely the +Bururi +Forest Reserve and Kinoso Nature Reserve, both of which are very small in surface area. The species occurs in a densely populated region, where clearance of its habitat for agriculture represents the main threat; a decline in the extent of occurrence, area of occupancy, extent and quality of the habitat, number of locations (sensu +IUCN 2012 +) and number of individuals can therefore be assumed. It qualifies as Vulnerable under conditions B1ab(i,ii,iii,iv,v) and B2ab(i,ii,iii,iv,v), and is likely to become Endangered in the near future. + + +Additional specimens examined:— + + +BURUNDI + +. +Munini +( +Mashuha +, préfecture de +Bururi +), source de la +Sikuvyaye +, + +22 September 1974 + +, + +P.

Lineolae densely spaced within each stria, discernible in LM in longer valves. + + + +FIGURES 14–20. +SEM images of + +Hippodonta fujiannensis + +. Figs 14, 17, 18. External view of entire valve. Striae uniseriate throughout the valve face and mantle. On one valve side, one column of lineolae closest to the raphe is positioned perpendicular towards remaining lineolae of the striae. Figs 15, 19. Close up of valve apices. Terminal endings of raphe distinct, strongly pronounced, teardrop-shaped depressions, positioned before terminal area or weakly advancing into it, slightly curved towards one valve side. Figs 16, 20. Close up of the central area. Central endings of the raphe small, teardrop-shaped depressions; central endings are positioned close together. Central area dissymmetrical. Scale bars in Figs 14, 18 = 5 μm; Fig. 17 = 2 μm; Figs 15, 16, 19, 20 = 1 μm. + + + + +SEM ( +Figs 14–32 +): + +Externally, valve face gently curved in transapical section merging gradually into valve mantle ( +Figs 14, 18 +). Raphe slits quite fine. Terminal endings of raphe distinct, strongly pronounced, teardrop-shaped depressions, positioned before terminal area, or weakly advancing into it, and slightly curved towards one valve side in smaller valves, or strongly curved in bigger valves ( +Figs 15, 18 +). Central endings of raphe small, teardrop-shaped, closely positioned depressions ( +Fig. 20 +). Central nodule clearly visible in girdle view ( +Fig. 23 +). Central area asymmetrical in bigger valves, with one side much bigger than the other ( +Figs 16, 20 +). Striae uniseriate throughout valve face and mantle ( +Figs 14, 17, 18 +). On one valve side, one column of lineolae, nearest to the raphe, is positioned perpendicular to remaining lineolae of the striae ( +Fig. 17 +). One the other valve side this column not as pronounced. Lineolae linear, +25–40 in +10 μm. Single rows of areolae surround valve apices. Prominent hyaline area present throughout valve mantle ( +Figs 21, 25 +). Internally, striae positioned on shallow linear depressions; thus, valve face not flat. Lineolae covered by hymens ( +Fig. 32 +). Central endings of raphe linear, closely positioned and gradually disappearing. Semicircular to rectangular hyaline area clearly developed in central area. Linear raphe slits distally terminated by weak, crescentshaped helictoglossae, weakly advancing into the terminal area. Terminal area strongly pronounced internally. Girdle band quite broad and unornamented ( +Fig. 24 +). Since the girdle is relatively broad, the frustules of + +H. fijiannensis + +often lie in girdle view or at an angle in valve view. + + + + +Etymology: +The species name + +“ +fujiannensis + +” refers to +Fujian Province +. + + + + +Distribution and ecology: +In our 25 sampling sites along the coast line of +Fujian Province +, + +H. fujiannensis + +was only found in the low intertidal zone of Haitan Island. The specimens of + +H. fujiannensis + +are infrequent in all of the samples from the Haitan Island; it is epipsammic ( +Figs 33–36 +) and inhabits the marine environment. + + + + \ No newline at end of file diff --git a/data/75/60/67/75606719A10DFFF9EFE3FEFEFC75E4C1.xml b/data/75/60/67/75606719A10DFFF9EFE3FEFEFC75E4C1.xml new file mode 100644 index 00000000000..36e8246315c --- /dev/null +++ b/data/75/60/67/75606719A10DFFF9EFE3FEFEFC75E4C1.xml @@ -0,0 +1,106 @@ + + + +Hippodonta fujiannensis sp. nov.
