( +Figs 1 +, +2 +) + + + + +Bisexual spiny glabrous succulent shrub 0.15–0.3 × +0.3–0.5 m +with many branches from similar stem, densely branched at ground level, with fibrous roots arising from base. +Branches +ascending to ± prostrate, 100–200 × +15–25 mm +, 3- to 4- angled, not constricted into segments, smooth, pale grey-green with paler stripes between angles; +tubercles +fused into 3 or 4 angles, laterally flattened and truncate, projecting ± +5 mm +from branch, with spine-shields +5–7 mm +long, +3–5 mm +long and rounded below spines but remaining well separated from next, bearing 2 spreading initially purple-red (later grey) spines ± +10 mm +long; +leaf-rudiments +on tips of new tubercles towards apex of branches, 8–10 × +5–6 mm +, erect, fleeting, ovatelanceolate, sessile, with small prickles ± +1.5 mm +long on either side at base. +Inflorescences +many per branch usually towards apex, each a solitary cyme in axil of tubercle, sessile, each cyme with 3 transversely disposed cyathia, central male, lateral 2 bisexual and developing later each on short peduncle 2–3 × ± +1 mm +, with 2 ovate bracts ± 2 × +1–2 mm +subtending lateral cyathia; +cyathia +shallowly funnel-shaped, glabrous, ± +5 mm +broad ( +3 mm +long below insertion of glands), with 5 pinkish red obovate lobes with deeply incised margins, grey-green variably suffused with red; +glands +5, transversely rectangular and contiguous, +2.5–3 mm +broad, dark yellow with red outer margins, spreading, inner margins slightly raised, outer margins entire and spreading; +stamens +glabrous, red, bracteoles enveloping groups of males, with finely divided red tips, glabrous; +ovary +3-angled, glabrous, green, raised on pedicel ± +1 mm +long; styles ± +2.5 mm +long, pinkish, branched to near base. +Capsule +± +4 mm +diam., obtusely 3-angled, reddish green, glabrous, nearly sessile. + + + + +Distribution & habitat +:–– + +Euphorbia pseudocontorta + +is only known in the central province of +Zambézia +, where it is found in shallow pockets of soil on low granitic domes at altitudes of + +500– +600 m + +. Plants are common in shallow soils on otherwise fairly bare rocks. + + + + +Discussion +:––This new species is similar to + +E. contorta + +, which occurs in shallow soil on granitic outcrops around the bases of larger hills some +150 km +further to the north-west at elevations of + +550– +700 m + +. + +Euphorbia contorta + +is sparingly branched, with the stem usually rising rather obliquely to +1 m +or more and a few horizontal branches spreading from it along its length. The new species is densely branched from the base, with the stem not visible among the branches. In + +E. contorta + +the stem and branches are an unmarked dull grey and are (4–)5- to 7-angled while in the new species they have a paler longitudinal patch between the angles and are 3- to 4-angled. Florally the two differ in the longer peduncles in + +E. pseudocontorta + +, both in the peduncle beneath the cyme and in the peduncles beneath each of the lateral cyathia in the cyme. + + + + +Conservation status +:––Not threatened. + + + + +Additional specimen examined +: +MOÇAMBIQUE +. +Zambézia Prov. +: +11 km +south of Alto Ligonha (1538CA), +570 m +, +11 November 2000 +, +Bruyns 8538 +(BOL). + + + + \ No newline at end of file
