I am indebted to M. Spach for tbe opportunity of examining a 
large suite of specimens of C. Boryana from tbe Herb. Mus. Paris, 
collected by Boivin and H. Richard in tbe Isle of Bourbon, and as 
in the case of C. Koestlini, I could not see any abrupt transition 
from the more compound to the simple forms, and I cannot but 
believe that the O. typhoides, Bory, is referable to tbe latter. In 
none was the perigynium more than 3 lines long, but in a specimen 
from the Mauritius in Herb. Hooker it varies from 3-J- to 4 lines 
in length. I have figured a perigynium from that specimen in 
Tab. CCCXLIX. 
Tab. CCCXLV. the lower part, and Tab. CCCXLYI. the up¬ 
per part, of a specimen of Richard. 
The others from specimens of Boivin, all from the Isle of 
Bourbon. 
Tab. CCCXLVIII. is the form like that found by Mann on 
“Clarence Peak, Fernando Po, 8500 ft. Dec. 1860” (Herb. Hooker).

This species has escaped the observation of authors, though de¬ 
scribed in the Transactions of the Linnean Society nineteen years 
previously to the publication of the ‘ Cyperographia’ of Kunth, 
Steudel, in his Synopsis, has not included it. Its affinity is with 
C. paludosa, Good., which occasionally has two stigmas. The 
transverse section of the perigynium in the Tab. CCCL. does not 
accurately show the plano-convex form.
