subsequantia, rigidissima, plana, glauca, margine minime sca- 
briuscula. Bractece inferiores 4-6 lin. late, spicis suis plus 
minus longiores, longe vaginate: superiores angustae, breves, 
demum evaginatse. Vaginae inferiores 4-7 poll, longae, basi 
ferrugineae. Pedunculi inferiores 7-12 poll, longi, laeves.

C. pendulce, Hudson, maxime aflinis !, et pro ejus evolutione 
maxima forsan habenda. DifFert spicis subcomosis, crassi- 
oribus, brevioribus, nec basi longe subverticillatim laxifloris, 
terminali vel terminalibus basi masculis; squamis longe cus- 
pidatis ; perigyniis majoribus; foliis rigidis, glaucis. 
Variat spica terminali flosculis masculis foemineisque per 
totam ejus longitudinem ;eque dispersis. 
Drejer has nowhere, to my knowledge, expressed any opinion 
as to the group to which 0. pendula belongs. He has merely re¬ 
marked that it and G. strigosa are to be exclud ed from his Phymeno- 
chlccnm. I am always glad to lean on his authority. Both C. pen¬ 
dula and G. Petitiana, with several American species, may, I 
think, be placed in a separate group with G. strigosa.

I am indebted to M. Spach for the knowledge of this species, 
which, as far as I know, has only been found by M. St. Hilaire. 
It belongs to the FEorostachyce of Drejer.

We are indebted to Dr. Torey and Mr. Curtis for settling the 
synonymy of this very beautiful species. No author has noticed 
the male florets at the base of the female spikes, which I find in the
