This species obviously approaches extremely close to S. ciliaris, but is not onl}’- very different in habit, 
but in the structure of the hypogynium, colour of the fruit, shape of the lobe that is opposite to the leaf, and 
in the want of the cilice on the bracteae and bracteolae. We have only seen one specimen sent by Mr. 
Millett, and another, but imperfect one, in Prof. Henslow’s collection. The spikelets are in pairs, one male, 
the other female.]

Perigynium immaturum lanceolatum, acuminatum, ore aeute bilobo, pubescens, maturum ovato-trigonum,

I The above observations seem to have been made by our friend to show' that this speeies was distinct from 
C. rarnosa, Schk. In that species, how'ever, Willdenow, on Schkuhr’s authority, asserts that there are only 
two stigmas, notwithstanding that the fruit is triquetrous ; it comes from the Mauritius. Sprengel combines 
with it a different plant, C. cruciata, Wahl, and Willd., and draws up a character, probably without 
seeing either, which partakes of both : C. cruciata, how'ever, is from Canton, nor is there anything in 
Wahlenberg’s description to induce us to suppose it distinct from the above C. valida, N. ab E., except 
where Wahlenberg says that the fruit has a short beak, while in our plant it is rather long; we consider 
them the same : the C. cruciata, N. ab E. 1. c. p. 123, from Nepal and the Peninsula of India, is quite dis- 
tinct, and is C. Hookeriana, Herb. Arn.]

[This we have not seen, nor does our friend Nees von Esenbeck appear to have met with any plant agree- 
ing precisely wffth Retz’s and Wahlenberg’s description: w'e have, however, a solitary specimen before us 
from Canton, which we suspect must be the same, an account of which w'e subjoin, as it differs in one or two 
points from the character usually given.
