Mr. Orcutt of San Diego claims familiar acquaintance with 

 two distinct oaks of the Lower Californian peninsula, both of 

 which he says were named by Dr. Engelmami " Q. pvngcnsJ^ 

 The real thing can not bo es:i)ected from that locality; and 

 the one of the two of which Mr. Orcutt has sent me specimens 

 is mj Q. iurbmella. 



Liebmann's type above alluded to is a Texan tree, and 

 apparently an excellent species, belonging to a remote dis- 

 trict which has seldom been visited by botanists, though 

 admirable specimens of leafy and fruiting branches, have been 

 collected and distributed since Charles Wright's time, chiefly

has larger, thinner leaves of a distinctly obovate general out- 

 line, and prominently lobed, the lobes being sharply jjointed. 

 To this Texan type Liebmann added a Californian specimen 

 from Lobb, the subject of figure 2 of his engraving ; and this 

 IS pretty certainly a very common state of Q. chrysolepis in 

 which the leaves are strongly and pungently toothed. So 

 then, that confusion which Dr. Engelmann carried to an 

 almost incredible extreme was begun by the author of Q. 



pnngens himself. 



In the herbarium of Mr. Lemmon I have seen sterile twigs 

 of a shrub from the summit of 3It. Graham in Arizona which 

 makes a near approach to the real Q, iinngens in its leaf 

 cliaracters. This is all I have in evidence of the occurrence 

 of the species to the westward to Texas ; and it is not 

 thoroughly satisfactory evidence. 



Q. TURBiNELLA, Greene, West Am. Oaks, 37 and 59, t. xxvii. 

 That slightly aberrant form of this species which occurs in 

 such abundance in the region of the Grand Canon in north- 

 western Arizona, is not at all referable to Q, pnngens, although 

 the last remark which I made concerning it in the West 

 American Oaks was the expression of a misgiving lest it 

 should so turn out. Q. turhuiella is an excellent species
