Shrubs or trees, to 8 m. Stems armed, sericeous, glabrescent. Leaves deciduous or persistent; petiole 3–10 mm, sparsely to densely villous (hairs tawny or reddish-brown to brown); blade (dull to lustrous adaxially), oblanceolate to spatulate, 23–64 × 6–22 mm, base cuneate to attenuate, margins plane, apex rounded to obtuse or retuse, abaxial surface densely sericeous (hairs tawny or reddish-brown to brown), venation obscured by hairs, adaxial surface glabrous or glabrate, midrib flat or slightly sunken, marginal vein absent. Inflorescences 8–40-flowered. Pedicels 4–12 mm, sericeous (hairs tawny or reddish-brown to brown).

Discussion

Sideroxylon tenax is a thorny shrub or tree characterized by sericious abaxial leaf surfaces, pedicels, and calyces with tawny, brown, or reddish brown hairs. Segregate species were named by Small based on widespread variation in leaf size, pedicel length, and fruit size. The segregate species were recognized by R. B. Clark (1942); A. Cronquist (1945c) and later workers have submerged them because of intergradation across the range of S. tenax.
