ON SOME SPECIES OF OAKS FROM NORTHERN CHINA. 31 
for the white edge of the scales of both kinds of its spikes gives it 
a silvery look very different from the dark hue of the C. precoz. 
The place where it grows is chalky and very dry, and there is an 
abundance of C. precoz in its neighbourhood. Although I have 
as yet only met with one patch of it, its restriction to that one 
spot is highly improbable; but unfortunately the chalk district of 
Cambridgeshire is so universally under the plough that few fit 
places for its growth now remain. It should be carefully looked 
for in similar places elsewhere in the south-east of England. 
It may be known by the following characters :—Its fertile 
spikes are more ovoid and closer together than those of C. precoz ; 
its glumes obovate, very blunt, with a pale margin, which is finely 
ciliated, especially at their tip ; their midrib does not reach to the 
tip; its fruit is obovate. The nut I have not been able to exa- 
mine, owing to the young state of the fruit. My specimens are 
about 3 or 4 inches high. 
It is the C. ericetorum of Pollick (Fl. Palatin. ii. 480. A.D. 1777) 
and of other authors, the C. ciliata of Willdenow (in Act. Berol. 
for 1794. p. 47. t. 3. fig. 2) and others. The latter name would 
be much more characteristic of the plant, but the dates of publica- 
tion conclusively determine that Pollick's name must be adopted.

[Read June 20th, 1861.] 
Ox returning from the late expedition to China, Dr. Daniell placed 
in my hands the specimens of several oaks which he had gathered 
on the shores of Taliewhan, a bay running into Southern Man- 
chouria, to the west of the Corea, and chiefly in a small valley 
about a mile from the sea, where they grew mixed with Pinus 
densiflora, Sieb., Salix Babylonica, L., &c. The specimens belong 
to six species, three of which are new and undescribed. Two of 
these species, however, want flowers and fruit, and although re- 
markable in the shape and characters of their leaves, and different 
from anything hitherto noticed, I have not ventured to name and 
describe them from the foliage only. Ihave added a fourth species 
which I found among the plants, now in the Herbarium of the 
British Museum, brought home by Sir George Staunton from 
Northern China. 
All of them, in which the fruit is known, belong to Blume’s
