THE CENTRAL AMERICAN SPECIES OF QUERCUS 53 



Trelease and here treated as synonyms are almost without exception 

 based upon variations in leaf size and shape which may occur indis- 

 criminately almost anywhere in the range of the species. Only Q. 

 parviglans f . polycarpa is based on any other character, and its several 

 fruits scattered on a larger peduncle constitute a tendency noted 

 variously in the species. The narrow-leafed form described as Q. 

 parviglans f. tejadana and as Q. apanecana seems to be confined to 

 El Salvador, but one specimen (Calderon 21+1+$ in the Arnold Arboretum 

 Herbarium) exhibits both narrow and broad leaves. Q. amissaeloba is 

 apparently based upon a juvenile form or a stump-sprout, for the type 

 collection has scarcely two leaves of the same size and shape. 



The specimen cited by Trelease as the type of Q. donnell-smithii 

 (Smith 1967) is obviously Q. sapotaefolia, but the illustration, which is 

 said to be made from that number, is clearly Smith 2629, a specimen 

 of Q. acatenangensis. The description also is undoubtedly based upon 

 the latter number. This is discussed further under Q. acatenangensis. 



A part of the material referred by Trelease to Q. wesmaeli (Pittier 

 2086) is composed of juvenile specimens one of which is accompanied 

 by several old leaves and is unquestionably to be referred to Q. 

 sapotaefolia. The type (Pittier 773) was collected in the same locality. 

 It has not been examined, but judging by the excellent photograph in 

 Trelease's illustration (pi. 344), it can scarcely be excluded from 

 Q. sapotaefolia. The other specimen illustrated on the same plate 

 (Tonduz 11827) must be referred to Q. borucasana.
