In this series of Carex, united by the American botanists under 
C. aristata, R. Br., the lower leaf-sheaths are of loose texture, 
with transverse lines and scattered needle-like white hairs; 
these hairs are continued up the under surface of the leaf, more 
orless. The utricle is glabrous in the lower half; in the upper 
portion it has sometimes white fine hairs on the angles or is 
slightly scabrous-pilose on the beak. In the ‘ Bot. Centralbl.’ 
Ixxvii. (1899) Kuekenthal has elaborately reviewed the material, 
and arranged it in four species and numerous varieties. It is 
true that the stems are much narrower in the Chinese plant than 
in the subarctic C. aristata type of R. Brown. The plant in 
Kuekenthal's C. amurensis sometimes is 30 in. high. The sheath 
of the lower bracts is 1 in. or 23 in. in the North-American type 
aristata. In C. trichocarpa, Muhl., the utricles have numerous 
minute small hairs between the nerves, different in character 
from the white needle-like hairs sometimes present on the beak 
of C. aristata. I have not seen any Asiatic plant that is = the 
American C. trichocarpa. At all events, I cannot accept 
Kuekenthal’s proposal to divide C. orthostachys, C. A. Meyer, 
into two species, and to put one of these into the North- 
American C. trichocarpa. The species are very close hereabout ; 
and I think Bailey’s proposal to collect the whole series under 
C. aristata, R. Br., quite worthy consideration.
