230 CHINA. [Cyperacca. 



membranacea nuda subulatis asperis, nuce (livide fusca) globoso-ovata obtuse subtrigona 

 leviter undulato-rugosa pubescenti-hirtula mucronata, mucrone concolore, hypogynio tri- 

 partite lobis lanceolatis nuce dimidio brevioribus. 



Hab. Circa urbem Macao ; Millett ; G. H. Vachell, n. 66. (ex parte.) 



This species obviously approaches extremely close to S. ciliaris, but is not only 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 cilise on the bractese 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 acute bilobo, pubescens, maturum ovato-trigonuin, 

 nervosum, parum pubescens vel glabrum, rostro brevi spatio bifido, ore primum membranaceo obliquo. 

 Squama! acutiusculte vel acuta?, nee mucronatse. Spicules paniculate potius sive thyrsoideae, quam corym- 

 bose. Folia lata, lsevia, margine scabra, supra trinervia. Culmus inferne crassitie pennas seriptoriae. 



[The above observations seem to have been made by our friend to show that this species was distinct from 

 C. ramosa, Schk. In that species, however, 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, however, 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. Hooheriana, Herb. Arn.]

[This we have not seen, nor does our friend Nees von Esenbeck appear to have met with any plant agree- 

 ing precisely with Retz's and Wahlenberg's description: we have, however, a solitary specimen before us 

 from Canton, which we suspect must be the same, an account of which we subjoin, as it differs in one or two 

 points from the character usually given. 



Summitas sola adest, glabra, triquetra, pedera longa. Bractem anguste lineari-aeuminatae, apice trique- 

 tral, margine scaberrimae, inferiores spicas proprias aequantes, superiores spicis breviores. Vagina! laxae, in- 

 ilato-tubulosae, membranacea?, lobulo oppositifolio brevi-rotundato. Spicat haud approximate nee tamen 

 distantes, in nostra 6, exsertse at haud longe pedunculatse, pedunculis inferioribus vagina duplo longioribus 1 J 

 unciara longis, erectae, cylindrical, laxiuscula;, floribus in nostra multis caducis, inferiores quatuor femineae, 

 quinta fere omnino feminea flosculo unico vel gemino masculo versus spicse basin, sexta seu summa mascula 

 attamen florsculis paucis ad spicae medium instructa, hinc forsan hermaphrodita. Squama patentes subu- 

 latae fructu paullo longiores, stramineae nervo carinali viridi. Stigmata tria. Fructus ventricoso-trigoni 

 basi attenuati apice rostrati, valde nervoso-striati, setulis brevissimis hispiduli, patentes, rostro rectiusculo 

 vel subrecurvo. Rachilla ad riorum insertiones excavata.
