Cyperaceai.] CHINA. 221 



[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 ravs 

 from an inch and a half to two inches in length, and two or three others scarcely three quarters of an inch 

 long; besides these there is a central almost sessile capitulum. In no other resnect, however, does it differ 

 from our friend's description above quoted. This is Mr. Vachell's n. 69.]

[Mr. Arnott has shown, in Wight's Contributions to the Botany of India, p. 77, that C.pectinatus of Rox- 

 burgh, which name Roemer and Schultes exchanged for C. pectiniformis, (there being a previous C.pectina- 

 tus), 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 dis- 

 covered 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 more frequently 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.]
