OAKS FROM NORTHERN CHINA. 33 
uniform obovate shape of the leaves, and the almost entire absence of the 
petiole (scarcely exceeding a line in length, as opposed to an inch in 
Q. serrata, Thunb.) strikingly separate it from that species. 
6. Quercus, sp. 
Hab. Taliewhan, Dr. Daniell. 
This is also a dwarf oak, from 6 to 10 feet high. It differs from Q. 
Chinensis, Bge., which seems to be its nearest ally, in wanting the glau- 
cous or canescent covering on the under surface of the leaf (both sides 
being equally glabrous, and nearly of the same colour), and in the remark- 
able panduriform shape of the nearly sessile leaf. The petiole is 1-2 
lines long. 
7. Quercus AcuTISsIMA. Foliis petiolatis, e basi rotundata vel obtusi- 
uscula ovato-lanceolatis acutissimis serratis, serraturis setaceo-excur- 
rentibus, venis et setis sursum spectantibus glabris; fructibus brevi- 
ter pedunculatis; cupule squamis sericeis, externis parvis, internis 
elongatis subulatis cupulam excedentibus. 
Hab. Chinese province of Kiangsi, Sir George Staunton. 
The form of the leaf separates this species from the last, and the gla- 
brous under-surface as well as the remarkable difference in the fruit 
separate it from Q. serrata, Thunb., under which name specimens of it 
have been distributed by Dr. Asa Gray. The veins and the sete are 
directed more upwards than in the allied. species. The petiole is 5-8 
lines long. 
On the identification of the Grasses of Linneus’s Herbarium, now 
in possession of thé Linnean Society of London. By Colonel 
Witt1am Munwo, 39th Regt., C.B., Chevalier of the Legion of 
Honour, F.L.S., &e. 
[Read April 4th, 1861. ] 
I BEG to offer to the Linnean Society, as the envied possessors of 
the original authenticated collections of Linnzus himself, the ac- 
companying notes on the identification of the various grasses con- 
tained in his Herbarium. 
Hoping that ere very long I shall be able to offer to botanists 
a full account of all grasses at present known in collections, I have 
devoted considerable time to the identification of the species of the 
earliest authors, with the view of clearing up some of the numerous 
mistakes in synonymy, which add so very much to the labours of 
any systematic botanist who wishes to treat any natural order in 
a really scientific spirit. Amongst grasses I find the errors ex- 
traordinarily numerous. Many of these might have been avoided 
by consulting herbaria easily accessible; and very many might
