32 MR. W. CARRUTHERS ON SPECIES OF 
section of the genus characterized by the acorn cup having imbri- 
cated scales, and named by Endlicher Lepidobalanus. They are 
1. Q. obovata, Bge. 5. Q.—sp. ? 
2. Q. Mongolica, Fisch. 6. Q.—sp.? 
3. Q. McCormickii, n. sp. 7. Q. acuminatissima, n. sp. 
4. Q. serrata, Thunb.

2. Quercus MowcoLica, Fisch; Ledebour Flora Rossica, vol. iñ. 
p. 589. Foliis petiolatis vel subsessilibus obovatis, basi auriculata 
sinuato-lobata, a medio ad basin euneato-attenuatis sinuato-lobatis, 
lobis sursum versis subacutis muticis a medio utrinque decrescentibus, 
sinubus acutis, subtus glaucis glabris; cupula squamis adpressis gib- 
bosis sericeis muricata, squamis superioribus parvis cupulam non ex- 
cedentibus; nuce ovata cupulam duplo excedente styli basi apiculata.

From the fine specimens given me by Dr. Daniell I have slightly 
amended the character of this species: this was the more needed to sepa- 
rate it clearly from the following. 
3. Quercus McConMickri. Foliis breviter petiolatis obovatis, basi 
lobata, a medio ad basin cuneato-attenuatis sinuato-lobatis, lobis sur- 
sum versis rotundato-obtusis muticis a medio utrinque decrescentibus, 
sinubus acutioribus, subtus glaucis, glabris vel rarius subtus ad venas 
pilis raris obsitis ; cupulæ squamis externis triangulatis sericeis, in- 
ternis membranaceis lineari-lanceolatis margine et apice ciliatis cupu- 
lam valde excedentibus; nuce rotundata cupule squamas vix exce- 
dente styli basi apiculata. 
Hab. From Taliewhan, Dr. Daniell. 
The difference between the foliage of this species and the preceding is so 
trifling, that, but for the fruit, it would be difficult to separate them. The 
shape of the acorn, and especially the scales of the cup, however, supply 
obvious and striking peculiarities. Instead of the compact scales of Q. 
Mongolica, Fisch., the cup is nearer that of Q. ebovata, Bge. ; but the 
scales are more compact, shorter, and more erect. 
4. Quercus serrata, Thunb. Flor. Jap. p. 176.

5. Quercus, sp. 
Hab. From Taliewhan, Dr. Daniell. 
This is a shrub, growing to the height of 6-10 feet. It appears to be 
nearly related to Q. serrata, Thunb., both having the leaves glabrous 
above and glaucous below, from a compact covering of small white 
hairs, and having also the veins running out into sete; but the
