About 50 species occurring from Florida south to Colombia, mostly on islands of the West Indies, with the greatest diversity (about 34 species) in Cuba. (J. Dransfield & N. Uhl & C. Asmussen & W.J. Baker & M. Harley & C. Lewis, Genera Palmarum. The evolution and classification of palms. 2008)A



Biology And Ecology



  • Small to moderate, solitary or clustered, unarmed or partly armed, pleonanthic, hermaphroditic palms. Stem slender, at first covered with fibrous leaf sheaths, then with a regular fibrous network or masses of long slender fibres or stout spines, eventually becoming bare, and closely ringed with narrow leaf scars. Leaves induplicate, palmate, ascending to spreading, marcescent; sheath sometimes long persistent and disintegrating into a regular fibrous network or masses of long slender fibres, or becoming ± spiny, covered with dense, deciduous tomentum (?always); petiole long, slender, flat to ridged adaxially, rounded abaxially, densely tomentose or glabrous; hastula prominent adaxially, triangular to ± rounded, absent or a very narrow ridge abaxially; blade fan-shaped, irregularly folded when large, divided to about the middle into long, rather narrow, pointed segments, tips usually bifid, glabrous adaxially, silvery, punctate, with hairs or glabrous abaxially; midribs prominent, lateral ribs sometimes conspicuous, transverse veinlets evident or inconspicuous on one or both surfaces. Inflorescences shorter than the leaves, slender, branched to 2 orders; peduncle rather short, slender; prophyll tubular, 2-keeled, pointed, opening apically; peduncular bracts several, like the prophyll but lacking keels, closely sheathing and overlapping; rachis longer than the peduncle, slender, bearing spirally arranged, tubular, overlapping, pointed bracts subtending rachillae; rachillae rather short, slender, bearing very small, spirally arranged, thin, pointed bracts (?bracts appear to be borne on the floral stalk where seen), each subtending a flower. Flowers solitary, sessile(?) or usually pedicellate; perianth broadly and shallowly cup-shaped with several (5–9) short points; stamens 9 (6–13), filaments slender, flat, shortly connate basally, not inflexed at the apex, anthers oblong or sometimes sagittate, dorsifixed near the base, latrorse, apically acute to briefly bifid; gynoecium of 1 carpel, unilocular, uniovulate, globose basally, attenuate in a long style terminating in a cup-like, ± laterally compressed stigma, ovule basal, erect, nearly orthotropous. Pollen ellipsoidal, with slight to obvious asymmetry, aperture a distal sulcus; ectexine tectate, perforate, or perforate-rugulate, aperture margin similar; infratectum columellate; longest axis 31–44 µm [3/50]. Fruit globose, purplish-black at maturity, rarely pink or white, stigmatic remains apical; epicarp smooth or rough, mesocarp thin or somewhat fleshy with flat, slender, anastomosing fibres next to the membranous endocarp. Seed globose, attached basally, deeply grooved, hilum rounded, basal, endosperm homogeneous except for grooves; embryo apical or subapical. Germination remote-tubular; eophyll entire, very narrow. Cytology: 2n = 36. (J. Dransfield & N. Uhl & C. Asmussen & W.J. Baker & M. Harley & C. Lewis, Genera Palmarum. The evolution and classification of palms. 2008)A
