animal, but at the first glance one should take the specimens as belonging 

 to the Mel ana ntha- group. 



A Carex-form collected in a salt-marsh on the shore of the lake 

 Bulung-Kul (Pamir, alt. 3800 m , August 19, 1898, No. 1185) belongs 

 probably also to C. orbicularis Boott, but it looks very different; the 

 stems are about 50 cm high, the leaves 20 — 30 cm long and 2,5 — 3 mm 

 broad ; as growing in a loose soil the rhizomes are not so tufted, but 

 with longer stolons. Taken as a whole it resembles Carex Goodenoughii, 

 but the essential characters, such as the flat leaves, the orbiculate utricles, 

 etc., are the same as in C. orbicularis. I therefore place it under this 

 species, but as a variety, var. bulungensis Ostf., nov. var. (Fig. 3).

 Supplement, p. 346; C. melanantha Auctt. ex parte. 



I have compared our specimens with the types in the Kew Her- 

 barium and found that they fully agree with them. The species is very near 

 C. Moorcroftii Falconer and C. melanantha C. A. Mey., which latter name has 

 been given to our specimens by the late G. B. Clarke, but differs from the 

 first named in its much darker scales of the female spikes, in the nearly 

 beak-less utricle and in the lack of the large covering masses of old 

 leaves and sheaths, from the second species in the wholly male terminal 

 spike, and the uppermost lateral spikes male being at the top.

27. C. macrogyna Turcz., Meinshausen, I.e., p. 357; C. ferruginea, 

 /?, Ledebour, Fl. Ross., p. 294; C. tristis Auctt., an M. Bieb.? 



The specimens agree very well with the plants of C. macrogyna, 

 which I have seen, but it must be admitted, that it is very nearly related 

 to C. tristis M. Bieb., from which it only seems to be distinguished by 

 the stouter growth, paler scales with broad membranous margins and 

 ovate utricles with short entire beak. 



G. B. Clarke had named it "Carex sp. 1 '.
