Coccothrinax borhidiana Muñiz in Borhidi, Imchanitskaya & Muñiz (1978: 437) . Lectotype (designated by Moya 2021 ):— CUBA . Matanzas , Punta Seburoco inter Jibacoa y Matanzas , 14 May 1970 , O . Muñiz 27118 ( holotype HAC !, isotype BP n.v. , BP image!). Plate 7 Stems length not recorded, 14.0 cm diameter, solitary. Leaves persistent, giving a ‘skirt’ of dead leaves covering the stem; leaf sheath fibers 0.5(0.4–0.6) mm diameter, thin, flimsy, loosely woven, free and greatly elongate at the apices; petioles 16.4(15.2–18.2) mm diameter just below the apex; palmans 19.8(18.0–21.5) cm long, relatively short, with the adaxial veins prominent and terminating in a slight raised ridge and distinct pulvinus; leaf blades not wedge-shaped; segments 34–35 per leaf, the middle ones 58.6(52.0–62.5) cm long and 3.7(3.0–4.5) cm wide; segments not pendulous at the apices, giving the leaf a flat appearance; middle leaf segments relatively short and broad, abruptly narrowed (shoulder) toward the apex, otherwise parallel-sided, often strongly folded, stiff and leathery, the apices briefly splitting; middle leaf segment apices attenuate; leaf segments not waxy or sometimes with a deciduous, thin layer of wax adaxially; leaf segments densely indumentose abaxially, with irregularly shaped, persistent, interlocking, fimbriate hairs, each one with a rounded, raised, light green to greenish-brown center, without transverse veinlets. Inflorescences erect, at least initially, amongst or above the leaves, with few partial inflorescences; rachis bracts narrow, closely sheathing, sparsely tomentose, usually without hairs at the apex; partial inflorescences 5; proximalmost rachillae straight, 9.2(7.0–15.0) cm long and 1.1(1.0–1.2) mm diameter in fruit; rachillae at or near anthesis not recorded; stamens 8; fruit pedicels 2.8(2.2–3.2) mm long; fruits 6.2(5.8–6.5) mm long and 7.1(6.3–8.0) mm diameter, black; fruit surfaces smooth or sometimes with projecting fibers; seeds not recorded. PLATE 7 . Coccothrinax borhidiana , Cuba, with stems covered with persistent dead leaves, giving a ‘skirt’ of dead leaves, and short petioles giving a compact crown of leaves. (Image by Héctor M. Díaz). Distribution and habitat:— Cuba ( Matanzas ) ( Fig. 10 ), open areas on sandy or rocky soils near the sea at 7 m elevation. Craft (2017) described the habitat as littoral scrub forest on dog’s tooth limestone. Taxonomic notes:— As a preliminary species, Coccothrinax borhidiana has a unique combination of qualitative character states and is recognized as a phylogenetic species. It appears similar to C. crinita in its elongate sheath fibers, differing in its persistent leaves, giving a ‘skirt’ of dead leaves covering the stem and smaller fruits. Petioles are relatively short, hence the compact crown of leaves.
