abruptly dilated stigmas. Fruit annual, rather small, solitary or 

 paired on a peduncle 2 to 5 mm. long; cups 12 or 13 mm. broad, 8 or 

 9 mm. high, turbinate or cup-shaped, the base strongly constricted, 

 margins not inrolled, the scales ovate, the narrowed apex rounded and 

 rather closely appressed, gray-tomentulose and partially glabrescent ; 

 acorns about 12 or 13 mm. long, 10 mm. broad, ovoid, obtuse at apex, 

 from finely pubescent becoming glabrate and light brown, about one- 

 fourth or one-third included (immature fruits merely smaller and the 

 nuts more pointed, not obviously juvenile). (See pi. 113.) 



Range: Chiapas, Mexico. 



Quercus paxtalensis is distinguished from the other annual-fruited 

 Central American species of the series Acutijoliae by its strictly 

 glabrous leaves and very slender petioles. 



Specimens examined : 



MEXICO. — Chiapas: Mount Paxtal [misspelled "Pasitar" on the labels], Au- 

 gust 3-4, 1937, Matuda 1724 (AA, DeP, Mi [3] [including the type], US, USNA). 



43. Quercus anglohondurensis sp. nov. 17 



Medium-sized or large tree. Twigs 1 to 2.5 mm. thick, fluted, from 

 loosely fulvous-tomentose soon glabrate and dark reddish brown with 

 rather prominent light lenticels, becoming gray. Buds 2 to 3 mm. 

 long, ovoid, glabrate, rather dull brown or grayish brown and lustrous; 

 the broad ligulate stipules soon caducous. Leaves evergreen or 

 appearing deciduous, rather thin but firm, 7 to usually 10 or even 16 

 cm. long, 2 to usually 3.5 or even 5 cm. broad, lanceolate or elliptic- 

 lanceolate, attenuately acute at apex, base attenuately cuneate or 

 merely cuneate or sometimes rounded, low-toothed or merely arista te 

 from the margin, in any event the teeth long-aristate-tipped, margins 

 minutely re volute and somewhat crisped, both surfaces glabrate and 

 shiny or stellate-pubescent along the midrib especially in the axils of 

 the veins beneath; veins about 10 or 12 on each side, often with evanes- 

 cent intermediates, branching and rather obscurely anastomosing but 

 passing into the teeth, rather prominent on both surfaces (including 

 the fine reticulum); petioles 5 to 16 mm. long, 1 to 1.5 mm. thick, 

 prominently winged nearly the whole length, from loosely fulvous- 

 tomentose becoming glabrate. Staminate catkins? Pistillate catkins 

 5 to 10 mm. long, 1- or 2-flowered on glabrous peduncles with conspic- 

 uous light lenticels, the elongate styles with abruptly dilated stigmas. 

 Fruit annual, solitary or paired on a peduncle 4 to 8 mm. long; cups 

 13 to 16 mm. broad, 10 or 11 mm. high, turbinate or deeply cup- 

 shaped, the base somewhat constricted, margin not inrolled, scales 

 ovate, the narrowed apex rounded, closely appressed, minutely fulvous- 

 puberulent or the brown margins glabrate; acorns (immature) 10 to 

 13 mm. broad, about as long, transiently buff-pub erulent, probably 

 about one-half included at maturity. (See pis. 114 and 115.) 



Range: British Honduras (about 1,000 m.). 



Quercus anglohondurensis is distinguished from the other annual- 

 fruited species of the series by its low, aristate teeth combined with its 

 usually long petioles and its rather promptly glabrate twigs. 



17 Quercus anglohondurensis sp. nov. — Arbor mediocris vel grandis, ramuli 1-2.5 mm. crassi glabrati, 

 gemmae 2-3 mm. longae ovoideae, stipulae late ligulatae mox caducae, folia decidua vel sempervirentia 7-16 

 cm. longa 2-5 cm. lata lanceolata utrinque attenuato-acuta vel basi rare rotundata dentata vel aristata gla- 

 brata vel costa subtus interdum pubescente, petioli 5-16 mm. longi glabrati, fructus annuus brevipedun- 

 culatus, cupula 13-16 mm. lata 10-11 mm. alta, squamae stricte appressae.
