Mr. D. Litwinow has separated the stenophylla-Yike Carex from 

 Turkestan from the true C. stenophylla Whbg., on account of its nearly 

 nerveless utricle with attenuated base and longer beak, and I find the same 

 distinctive character in all the specimens with ripe fruits collected by 0. 

 Paulsen in Asia-Media. The utricle is thin-walled, at least in its basal 

 part, and the nut does not fill it out, but I do not base a new species 

 on these few characters alone, and therefore 1 take the Central-Asiatic 

 form as var. desertorum Litw. of C. stenophylla; of the beneath men- 

 tioned numbers the no.'s, 110, 476, 559 and 1625 agree exactely with 

 the specimens of var. desertorum distributed in the quoted exsiccatum 

 (Kneucker, no. 153).
