3. Magnolia oblongifolia (León) Palmarola in Palmarola et al. (2016: 3).

Type:— CUBA. Holguín: Monte de la Breña, Sierra de Moa , Moa , Oriente , 1 Jul 1945, León, Alain, Clemente & Crisógono LS-22588 (holotype: HAC ex-LS SV-10692!) .

Homotypic synonyms: Talauma minor var. oblongifolia León (1950: 5) . Talauma minor subsp. oblongifolia (León) Borhidi (1971: 6) . Talauma oblongifolia (León) Bisse (1974: 589) .

Heterotypic synonym: Talauma ophiticola Bisse (1974: 589) . Type:— CUBA. Holguín: Baracoa , Mina Iberia , en las orillas del arroyo Iberia , April 1968, Bisse & Köhler HFC-6519 (lectotype: HAJB 634 !, designated here; isolectotypes: JE 1224!, 1225!, HAJB 635 !) .

Trees or shrubs up to 14 m tall, 0.23 m in diameter. Leaves with petiole 0.8–3.4 cm, leaf blade 7.9–19.7 × 2.5–6.4 cm, oblong-elliptic to oblanceolate, length-width ratio (2.21–) 2.5–4.66, apex round, retuse-emarginate or acute, base cuneate, adaxial surface dark green, abaxial light green, glabrous, reticulate-veined on both sides, midrib flat above, prominent beneath. Flowers terminal, sepals 3, ovate-linear, obovate or rounded, initially greenish white, up to 3.0 × 2.0 cm, petals 6, cream, in two cycles, the 3 outer petals elliptic up to 2.5 × 1.1 cm, the inner petals narrowly ovate and apiculate, up to 2.3 × 0.7 cm, stamens up to 30, linear, cream to white, from base to connective about 0.5 cm, gynoecium 5–8 carpels, pubescent, brown to ferruginous hairs. Polyfollicle irregular elliptic-rhombic, 3.0–4.5 × 3.0– 4.5 cm.

Phenology:— Flowering all year, fruiting February–September.

Notes:— In the protologue of T. ophiticola , the type is indicated to be at HAJB, but which of the two specimens is the holotype is not indicated (HAJB 634, 635; Bisse 1974). Palmarola et al. (2016) recognised HAJB 634 as the holotype, but this cannot be considered effective lectotypification (termed “inadvertent lectotypification”) since (as of 1 January 2001) the phrase “designated here” or an equivalent is required ( Turland et al. 2018: Art. 7.11). For this reason, T. ophiticola is lectotypified here with the material of Palmarola et al. (2016).

As presented here, Magnolia oblongifolia has the same limits as proposed by Bisse (1974, 1988) for T. ophiticola . Therefore, it has a reduced circumscription from that proposed by Palmarola et al. (2016; Fig. 1 ) because it does not include gatherings considered by Bisse (1974, 1988) as T. oblongifolia (except the type), in which the leaves are on average twice as long as wide. Confusion over M. oblongifolia and T. ophiticola was caused because the latter was based on Bisse & Köhler HFC-6519 (HAJB 634; Fig. 2A ), which is similar to the type of T. minor var. oblongifolia (León et al. LS-22588, HAC; Fig. 2B ). The types of these two names reflect the morphological variability of this species ( Fig. 2 ). Therefore, the correct name for gatherings considered T. ophiticola by Bisse (1974, 1988) is M. oblongifolia . This confusion was not clarified by Palmarola et al. (2016).

Distribution:— Endemic to north-eastern Cuba, Holguín, Guantánamo and Santiago de Cuba Privinces, in rain and pine forest, 0–1,000 m a.s.l., in serpentine soils.
