 southern boundary line. An evergreen oak, 30-40 feet high, with pale hark. The heart-wood 



is dark-colored^ and it is said to be good timber. The acorns are often of great size and the 



cups extremely thick, as represented in my figure of Q. crassipocula, but sometimes not la: 



than those of the Live Oak (Q. virens). We adopt Liebmann's earlier name for this beautiful 



species. 



QuERCUS nuMOSA, Nutt. Sylv. 1^ p. 7? Near San Diego, California; Parry. A shrub, 5-8 

 feet highj and very densely branched. The leaves are semjiorvirent^ ovate, and 8-10 lines long. 

 Our specimens accord well with Nuttall's description; but he did not see the acorns. These are 

 sessile, solitary and in pairs, about three-quarters of an inch long ; the cup hemispherical ; the 

 gland ovate-oblong, tapering to a point and scarcely more than one-third of an inch in diameter 

 at the base. Dr. Parry states in his notes, that the leaves are sometimes larger and oblong. 



QuERCus ACUTiDENS (n. sp.): foliis oblongis coriaceis basi acutiusculis vol cuneatis inequaliter 



grosse dentatis, dentibus cuspidatis pungentibus supra glabris nitidulis subtus pallidis minute 

 1 tomentosis; fructibus sessilibus solitariis ; cupula hemispherica, squamis incrassatis; glande 



oblongo-ovata. (Tab. LI.) Near San Luis Rey, California ; Parry. — ^' Generally alow shrubby 

 bush; but sometimes a tree 20 feet high.'' The leaves are 1^-2 inches long and 8-10 lines 

 wide. The acorns are more than an inch long and much resemble those of the White Oak (Q. 

 alba) . 



QuERCUS CONFERTIFOLIA, H. B. K. PL JEquiu, 2,^. 53, t. 94? Near the Copper Mines, New 

 Mexico; Thurher] No. 1869, Wriglit. Sierra del Pajarito, Sonora ; ScJiolt. San Francisco 

 mountain; Captain E. K. Smith. — A small tree. Liebmann seems to have referred it to Q. 

 cinerea, as he includes that species in his list of New Mexican Oaks (doubtless of Wright's 

 collection) which he examined in the herbarium of Sir William Hooker, and Mr, Wright found 

 no other Quercus in New Mexico resembling Q. cinerea. Our plant has thickly coriaceous, 

 lanceolate, acute leaves, which are 3-4 inches long, and from three-quarters of an inch to nearly 

 an inch broad. They are commonly entire and revolute on the margin, but occasionally show 

 1-3 minute teeth, nearly smooth and pale green above, very densely yellowish-tomentose 

 underneath. The acorns are nearly sessile, solitary and in pairs ; the cup hemispherical with 

 broad, obtuse, pubescent scales, and the unripe acorn is ovate. Q. cinerea differs in its much 

 thinner non-revolute leaves, and thin pale pubescence. The acorns also seem to differ, but we 

 have not seen the ripe ones of Q, confertifolia.
