Our plant has the inflorescence more elongated than Roxburgh attributes to his species, but all other points
seem to agree ; the filaments are quite glabrous. It differs from T . thyrsiflora of Blume by the sheaths
being ciliated or almost bearded at the mouth and along the margins.

[The Cyperaceoe and Ch-amineoe form the most numerous and valuable part of the collections received
from Canton, and from the extreme vagueness with which the Chinese and East Indian species of both
orders have been usually described, it is necessary that they should be noticed more in detail than the
other families. For the following account of them we are indebted to our friend Prof. C. G. Nees von
Esenbeck of Breslau: and when we have added any species not elucidated in his MS., or have made any
additional observations of our own, we have inserted them within brackets. The mere specific characters of
most of the Cyperaceoe have been already published in Wight’s Contributions.]

[One of the specimens before us, from Macao, contains more rays to the umbel than is noticed by Prof.
Nees von Esenbeck : he limits it to having only from one to three rays ; we find three or four principal rays
from an inch and a half to two inches in length, and two or three others scarcely three quarters of an inoli
long; besides these there is a central almost sessile capitulum. In no other respect, however, does it differ
from our friend’s description above quoted. This is Mr. Vachell’s ii. 69.]

[Mr. Arnott has shown, in Wight’s Contributions to the Botany of India, p. 77, that C.pectinatus of Roxburgh,
which name Roemer and Schultes exchanged for C. pectiniformis, (there being a previous C. pectinatus),
is not the same as the present species, but is C. Wightii, N. ab E. The plant here described has been
therefore named C. Meyenii by Wight and Arnott (Wight Cat. n. 1815) in honour of Meyen, who first discovered
it in the island of Manilla.]

[The Chinese specimen which we have received from Prof. Henslow has the umbel simple, as described
by Prof. Nees Von Esenbeck; but in those from the Peninsula it is morcffrcquently compound, as noticed by
Roxburgh : the mucro to the scales is often straight and patulous, but is usually slightly recurved ; Roxburgh
has described and figured this form.]
