100 MEMOIRS OF THE NEW YORK BOTANICAL GARDEN [Vol. 9, No. 1 



soil on grasslands, bright green clumps about 1 m. high, immature, 2 100 m., July 3, 

 Rhodesia, Tanganyika Territory, Mozambique. 



Eriospora Hochst. ex A. Rich. (1851) is a later homonym of Eriospora Berk. & 

 T3r t (1850), which is in use for a genus of fungi, and Trilepis is a distinct and 

 mainly American genus. Hutchinson, having to deal with E. pilosa for the Fl. W. 

 Trop. Africa (2: 490. 1936), transferred it to Catagyna Beauv. Gilly, however, ar- 

 gues (Brittonia 5: 13. 1943) that "the exact application of this generic name can 

 be determined only if the Dupetit-Thouars specimen [on which Catagyna was 

 founded] can be found; on the basis of the spikelet and achene characters, the 

 name would seem to be based on some species of Scleria, V and he proposes the 

 new genus Coleochloa to accommodate all the African species of Eriospora with the 

 exception of E. pilosa itself, which he transfers to Trilepis. Until Catagyna is 

 known with more certainty, it seems better to use Gilly's combinations under 

 Coleochloa than to make new and what may prove to be superfluous ones under 

 Catagyna. 



Coleochloa sp. 



Zomba District: Zomba Plateau, plentiful in small clumps on an exposed rocky 

 summit; very pubescent; 1820 m., May 31, 1946, 16133. Apparently a new species 

 but too immature to describe.
