 in a sliort, blunt, distinct point ; pale brown in colour ; testa 

 thick, superior portion covered with a dense caducous cine- 

 reous pubescence ; length Ijjj inch, diameter yV inch : cup

 in stiff recurved booklets, covered with a dense cinereous pu- 

 bescence, which extends down to the peduncle ; interior pale 

 brown, and covered with a long fibrous pubescence ; depth 

 T% inch, breadth at mouth —^ inch, length of peduncle, when

Hah. Canon Creek, Oregon, and up to 8000 feet above the 

 sea-level on other portions of the Siskiyou JMountains. 



This species I first found plentiful, in the autumn of 1865, 

 in Canon Creek, a locality peculiarly prolific in species of 

 Cupuliferaj and Conifers?, as my collection (of which it is 

 " Quercusy sp. (e). No. 250 ") testifies. It is a small shrub, 

 growing to a great height above the sea-level, which Q. densi- 

 Jlora, 11. & A., to which it is closely allied, does not. I am, 

 however, doubtful whether it is not identical with that species, 

 of which Q. echinacea, Torr. (Botany of Whipple's Pacific 

 Railroad Report, p. 137), is only a lanceolate entire or sinuately 

 entire variety, both forms being frequently found on the same 

 tree. I am therefore doubtful about its specific identity when 

 the type of the group to which it belongs is so variable. For 

 the present, however, I may indicate it as new, the specific 

 name pointing to its nearest ally. It will therefore belong to 

 Oersted's subgenus Eiqxisania of the genus Pasania ( Quercus, 

 sect. Pasania, Miq., et Chlamydohalanus, Endl. pro parte) of 

 the subfamily Castaninae, the characters of which, how- 

 ever, require to be somewhat modified. Q. echinoides, among 

 other characters, has much smaller leaves (which never assume 

 the chestnut form) than Q. densifora. The cup is deeper, and 

 the acorns more ovoid and very bitter, so bitter, indeed, that 

 nothing but squirrels Avill eat them ; so bitter are they that 

 even the black bear will not eat them, unless pressed by 

 famine. The miners and hunters living in the section of 

 country where it is found always look upon it as a separate 

 species from the water-oak [Q. densijlora).
