Magnolia minor (Urb.) Govaerts in Frodin & Govaerts (1996: 71) . Type:— CUBA . Wright 1100 ( B 100248228!, lectotype , designated by Palmarola et al . 2016 ; possible isolectotype: BM 574752!). Homotypic synonyms: Talauma minor Urban (1912: 7) . Svenhedinia minor (Urb.) Urban (1927: 3) . Trees up to 30 m tall, 0.76. 8 m in diameter. Leaves with petiole of 1.5–5.0 cm, leaf blade 8.0–17.7 × 4.8–10.7 cm , elliptic, length-width ratio 1.14 to 2.48(–2.58), apex round, obtuse, sometime retuse or truncate, base round, obtuse, adaxial surface dark green, abaxial light green, glabrous, prominently reticulate-veined on both sides, midrib flat above, prominent below. Flowers terminal, often paired, sepals 3, oval–linear, initially greenish white, quickly turning brown, up to 2.6 × 1.4 cm , petals 6, cream, in two cycles, the 3 outer elliptic or elliptic-cuneate, up to 2.5 × 0.8 cm , the inner petals narrowly ovate-cuneate, apiculate, up to 2.4 × 0.6 cm , stamens up to 23, linear, cream to white (from base to connective 0.4 cm ); gynoecium 5–8 carpels. Polyfollicle spherical or elliptic, 1.6–4.0 × 1.2–3.0 cm. Phenology: —Flowering January–December, fruiting January–August. Notes: — Magnolia minor (Urb.) Govaerts expanded their species limit from the proposed by Bisse (1974 , 1988 ), Imchanickaja (1993), and Palmarola et al. (2016) to include the individuals considered by Bisse (1974 , 1988 ) as Talauma oblongifolia (except the type ) ( Fig. 1 ), which were treated by Palmarola et al. (2016) as part of the variability of Magnolia oblongifolia (León) Palmarola , which also includes Talauma ophiticola Bisse. Palmarola et al. (2016) considered seven isolectotypes without these being mentioned in the original description by Urban (1912) . This confusion was caused by material collected by Wright ( Wright 1100 , 1860–1864) in at least two localities (with different labels). When dealing with Wright’s collections, it is necessary to question their status as duplicates because, generally, one number includes material from several collections ( Howard 1988 ). The material with different types of labels likely belongs to different gatherings and, therefore, are in fact not duplicates. In the protologue of M. minor , Urban (1912) only mentioned the localities of the Shafer material ( paratypes ), and the type only mentioned Cuba . Because Urban did not mention Monte Verde, it can be inferred that he did not study the duplicates with the second type of label. In this way, the material from BM could be a duplicate of that at B, but those from the other herbaria are definitely not from the same gathering, so they should not be considered isolectotypes. Distribution:— Widespread in north-eastern Cuba in rain forest, pine forest, secondary forest, gallery forest and plantations between 0-800 m a.s.l., in limestone derivative and serpentine soils.
