Small to large tree. Twigs 1.5 to 2.5 mm. thick, fluted, glabrous or 

 from loosely tomentose or stellate-pubescent glabrescent or persist- 

 ently floccose, light brown to dark reddish brown with numerous prom- 

 inent light lenticels, grayish the second season. Buds about 3 mm. 

 long, 1.5 mm. broad, acute, glabrous or the scales ciliate, reddish 

 brown; the stipules caducous. Leaves evergreen, often persisting 

 through three seasons but sometimes deciduous early in the second, 

 thick and very coriaceous, 4 to usually 8 or often 12 cm. long, 1 to usu- 

 ally 2.5 or even 4 cm. broad, oblanceolate to oblong or elliptic-oblong, 

 often broadest above the middle, narrowly rounded and aristate-tipped 

 to usually broadly or narrowly rounded and not apiculate at apex, 

 cuneate to usually narrowly rounded or broadly rounded or even cordu- 

 late at base, entire, the margins rather coarsely re volute and much 

 crisped or sometimes not, upper surface dull to markedly nitid, gla- 

 brous, lower surface not bullate, somewhat shining, in age becoming 

 more nitid or usually waxy -glaucous, usually glabrous or with incon- 

 spicuous domatia, occasionally rather persistently floccose; veins about 

 10 to 14 or even 18 on each side, repeatedly branched and obviously 

 anastomosing near the margin, slightly or not at all depressed above, 

 in any event both the principal veins and reticulum slightly raised 

 above, more prominently so beneath; petioles 2 to usually 4 or even 

 7 mm. long, glabrous or from stellate-pubescent glabrate with the stem. 

 Staminate catkins 5 to 8 cm. long, rather loosely flowered, sparingly 

 short-villous, the apiculate anthers well exserted. Pistillate catkins 

 1- to 3-flowered or rarely 6- or 8-flowered, subsessile to usually pedun- 

 culate, the peduncle 2 to about 20 mm. long (usually under 10). 

 Fruit annual, solitary, paired, or in threes or more, subsessile to usu- 

 ally pedunculate, the peduncle 1 cm. long or less with distal fruit or 

 up to 3 cm. long with more numerous scattered fruit; cups small or 

 moderate, 8 mm. broad and cup-shaped, the scales broadly ovate, 

 very thin and tightly appressed, sparingly sericeous-pubescent or 

 glabrate and light brown and shiny; acorns about 15 mm. long, usu- 

 ally 7 mm. broad, ovate or usually narrowly elliptic, finely sericeous- 

 pubescent or glabrate, light brown, about one-fourth included. (See 

 pis. 68 to 70.) 



Range: Chiapas, Guatemala, British Honduras, Honduras, El Sal- 

 vador, Costa Rica, and Panama (near sea level to usually 1,000 to 

 2,000 m.); type from Costa Rica (Skinner 6). 



Quercus sapotaefolia is relatively constant in all its characters except 

 leaf shape (although the rounded apices are rather dependable). Its 

 rounded leaf apices separate it from Q. eugeniaefolia, which also has 

 veins impressed above. The lack of evident lenticels, usually densely 

 short-velvety-tomentose twigs and petioles, larger and characteris- 

 tically acuminate cordate and impressed-veiny leaves of Q. hondurensis 

 may be depended upon to distinguish that species from Q. sapotaefolia.
