Monographs Details: Samyda mexicana Rose
Description:Species Description - Erect shrub to 3 m tall. Branchlets villous-velutinous at tips, older parts glabrate, covered with grayish to reddish-brown cork. Leaves resembling much those of certain forms of Casearia aculeata, distichous, elliptic, oblong-elliptic or elliptic-obovate, apex rounded to short-acuminate, rarely emarginate, chartaceous to subcoriaceous, appressedly villous to velutinous when young, generally more densely so beneath, glabrate or not with age, densely pellucid-punctate and -lineate, distantly glandular-serrulate-crenulate or sometimes subentire, 3.0-7.0(-11.0) cm long, 3.0-5.5 cm broad, lateral nerves 6-8(-9) pairs, more or less arcuately ascending, prominulous above, more distinctly so beneath, veins and veinlets a little raised on both faces; petiole pubescent, not rarely glabrate, 2.0-7.0 mm long; stipules broadly lanceolate, subulate distally, persistent, up to 2.0 mm long. Flowers l-2(-3) per axil, sometimes aggregate due to condensation of internodes, together forming a leafy terminal inflorescence, fragrant; bracts connate initially, subsequently separating to the base, broadly ovate, acuminate, convex, keeled and short-velutinous outside, 2.5-4.5 mm long, tardily caducous; pedicels villous-velutinous, 2.0-6.0 mm long. Calyx (4-)5-merous, 6.0-14.0 mm long, cylindric- to broad-campanulate, abruptly tapering towards the base, whitish to greenish and villous-velutinous outside, tube 2.0-7.0 mm long, glabrous inside, limb 4.0-7.0 mm long, lobes oblong to orbicular-elliptic. Androecium almost completely fused, tube 2.0-3.0 mm long, sparsely hairy outside. Stamens 10-12; anthers ovate-triangular, subsessile, ca 1.0 mm long; staminodes distinct, the free tips short to fully as long as the anthers, more or less densely villous. Ovary narrowly ovoid, rather densely appressed-velutinous; style sparsely hairy; stigma depressed-globose. Fruit obovoid-ellipsoid to depressed-globose, obtusely 3-gonous, sparsely villous to glabrate, 0.6-2.0 cm long; valves 3, becoming woody after dehiscence; seeds brown, 3.0-4.0 mm long.
Distribution and Ecology - Mexico, apparently sparse near and along the Pacific coast (Colima, Guerrero, possibly also in SW Michoacan between); in forest, chaparral, and on exposed headlands, 40-300 m alt.
Discussion:A polymorphic as yet poorly known species, apparently closest to Samyda yucatanensis, consisting of a number of small isolated populations.
