A NEW CYPERUS FROM THE EAST-AFRICAN ISLANDS. 

 By R. A. RoLFE. 



In a small collection of plants from the islands of the Indian 

 Ocean, sent to Kew by Dr. Coppinger, of H. M. S. Alert, the 

 following undescribed species of Cyperus occurs : — 



Cyperus glandulosus, n. sp. — Perennial, tufted. Stems 1^-2 ft. 

 long, triquetrous. Leaves narrow linear, shorter than stem, or 

 longer in vigorous specimens. Umbel simple, 5-8-rayed, bracteated 

 by 3-4 long linear leaves; jDeduncles 0-2 in. long; S2:)ikelets 

 arranged in dense ovoid clusters, J in. long, 4 flowered. Glumes 

 red-brown, ovate, acute, 8-striate, and lightly keeled. Achene 

 trigonous, brown-black, half the length of the glume ; style slender, 

 with three long, slender stigmas. Marisciis glandulosus, Bojer ! 

 Hort. Maur. p. 382 (name only). Galega Island, E. Africa, Bojer! 

 Eagle Island, Amu-ante group ; and Providence Island, Mascarene 

 group ; Coppinger. 



It belongs to the section Mariscus; Bojer's type specimen is at 

 Kew, thus enabling me to identify the plant. His name is not a 

 good one, but I have thought it best to retain it.
