times wanting, especially in the larger specimens, which are as

11. Cyperus Papyrus, Linn.—Kunth, Enum. 2. p. 64.—Very 
abundant on the banks of the Lagos, a river near Accra, 
Don. Evidently the same species as the Egyptian Pa- 
pyrus. 
12. Cyperus exaltatus, Retz.—Kunth, Enum. 2. p. 70.— 
^ St. Thomas, Don. 
This specimen is precisely similar to the n. 3328 of Wal- 
lich’s Catalogue from Rajemahl, which has much fewer flowers
