  • Description

    Species Description - Shrub or tree, 2.0-6.0, rarely -12.0 m high; trunk rarely up to 40.0 cm diam, usually armed with strong compound spines; branches with simple spines up to 4.5 cm long. Branchlets slender, flexuous, tips puberulous or glabrous, older parts whitish-grayish-corticate, laxly lenticellate; axillary spines up to 1.5 cm long. Leaves alternate or not rarely borne in fascicles at the end of short pseudobranches, considerably variable in form, size, texture and dentation maybe upon a single plant, usually elliptic or obovate, (generally narrowly so), or ovate-elliptic, or rarely rhombic-ovate, apex subacuminate or obtuse, sometimes rounded, maybe even a little retuse, base attenuate to cuneate, very base often obtuse, rarely rounded, rigid-chartaceous to (sub)coriaceous, lustrous above, dull beneath, glabrous or very rarely short-pubescent at midrib and lateral nerves beneath, then glabrescent, margin generally hardly or not revolute, usually rather sharply glandular-crenate-serrate (more deeply so in sterile offshoots), rarely subentire, 2.5-6.0(-8.0, very rarely -10.0) cm long, (1.0-)1.5-3.0(-4.5, -6.0) cm broad, lateral nerves (5-)6-8 (rarely -10) pairs, generally markedly raised on both faces as is the more or less dense reticulation of veins and veinlets; petiole rather robust, (1.0-)3.0-5.0(-7.0) mm long. Flowers dioecious, though occasionally [female] ones with a few staminodes around the ovary may occur, 4-8(-12) together in short contracted racemes or in fascicles both from foliate and defoliate axils; bracts narrow-ovate, puberulous, 1.0-1.5 mm long; pedicels articulate a little above base, slender, glabrous or puberulous, 2.0-6.0 mm long. Sepals 4 or 5, ovate or narrowly so, subacute, greenish, yellowish or white, subglabrous or usually puberulous on both faces, ciliolate, (1.0-)1.5-2.0 mm long, 1.0-1.5 mm broad. Disk-lobes ca 8, more or less fused into a crenate annulus, [male]: stamens 16-20(-30); filaments very slender, glabrous, 2.5-4.0 mm long. [female]: ovary oblong-ovoid, glabrous; style very short, stigmatic lobes 2 or 3, flattened, recurved, often irregularly lobed. Fruit globose, red, 5.0-6.0 mm diam, on pedicel elongated to 10.0 mm and articulate ca 2.0 mm above base; seeds -6, ovoid-angular, 3.0-4.0 mm long.

    Distribution and Ecology - From S Texas to Panama, Venezuela (Falcón, Lara; also in Merida?), on Curaçao; in mixed wet or dry (seasonal) forest or thickets, also in Pine-Oak-forest, not rarely in secondary growth, invading overgrazed land, along roadsides, from lowland to 1800 (rarely -2500) m alt.

  • Discussion

    Xylosma flexuosum is conceived here in a broad sense; it comprises numerous local, probably ecologically generated forms, flexible or adaptable as the species to be, to a broad scale of different habitats. Close to Xylosma benthamii.
