MR. C. B. CLARKE ON CAREX WANLENBERGIANA. 297 
Boeckeler's description of the lonz-stalked nut applies to the 
next species. 
2. Carex STEUDNERT, Boeck.! in Linnea, xl. (1876) p. 361.— 
Utriculi 7-8 mm. longi, lineari-lanceolati, trigoni, pilosi. Nux 
lineari-oblonga, in stipite lineari conspicue sustenta. 
Carex Wahlenbergiana, var. 6, Boott! Carex, ii. (1860) p. LOL, 
t. 304; Boeck. in Linnea, xl. (1876) p. 857 partim. 
Hab. in Abyssinia: Tigré, Schimper, n. 1559 (in hb. Kew); 
Mt. Silhe alt. 3000 metr., Schimper n. 545 (in herb. Boott). 
This species is very strongly characterized by the long narrow 
utricle, and differs much from C. Wahlenbergiana in habit and 
in minor characters, as is well shown by the figures of Boott and 
the description of Boeckeler.
