There are specimens from two places in Pamir, which I refer to 
C. graeilis; they are rather different from the ordinary type of this species 
having short erect female spikes, but in all essential characters they agree 
with it (phyllopod, flat leaves, etc.).

July 28, 1898.

tember 6, 1898.

Transact. Linn. Soc. XX, 1851; p.134, Clarke in Hooker, Fl. Brit. India, 
p. 711 as synon. to C. rigida. 
In the material of Carices from Pamir there are several numbers of an 
interesting species in many respects intermediate between C. Goodenoughii 
Gay and C. rigida Good (see Fig.2). The late C. B. Clarke had named the 
specimens C. vulgaris Fr. (= C. Goodenoughii}, and on the other hand I 
was inclined to identify them with ©. rigida. Now we have in the 
Copenhagen Herbarium a Carex from “Herb. Ind. Or., Hooker fil. & Thom- 
son” collected in West-Tibet, regio alp., alt. 14—16,000 feet, which is 
quite the same form as the Pamir plant, and this species is named C. 
orbicularis Boott. I have not seen the preliminary description of C. orbi- 
cularis by Boott in 1845, but the diagnosis and the full description in 
Boott’s paper from 1854 agree well with our plant. Therefore I use 
Boott’s name for it. It deserves certainly a specific rank in spite of its 
relations to the above mentioned two species, of which it probably is the 
Central-Asiatic mountain representative. As an addition to the description 
given by Boott I will mention the following characters: 
Tufted, with short stolons; old leaves and sheaths persistent; leaves 
rather short, 3—3,5 mm broad, flat (with papillose epidermis-cells on 
both surfaces), glaucous; stems 10—20 cm high; one terminal male spike 
with obtuse more or less darky brown scales; 2—3 short globose or 
ellipsoid female spikes, sometimes with male flowers in the top, sessile 
or the lower very shortly stalked; bracts very short, not sheathing, with 
blackish ears, blade of the lower one shorter than the spike, setaceous, 
those of the others mostly wanting. Scales of the female spikes obtuse, 
blackish or black-brown with lighter midvein and margins, shorter and 
narrower than the mature fruit; utricle orbiculate or obovate. about 
2—2,5 mm long, apiculate with a short entire beak, plano-convex, nerve- 
less, mostly black-brown, when mature, with exception of the basal part, 
faintly papillose; nut orbiculate or obovate, biconvex or plano-convex, api- 
culate; stigmas 2.
