Nonh American Cypcracea. 343 



Obs. I have not had an opportunity of examining this plant. 

 If it really belongs to the tribe Scirpese, its place is next to 

 MalachocJuttc, N. ah E., which differs in the scales of the pe- 

 rigynium being -5 or 6, instead of 2. It may, however, be 

 more nearly related to the Hypolytrea^, if not a species of Hy- 

 polytrum* itself.

* The genus Hypolytrum, as characterized by Richard, included also 

 what is now called Lipocarpha. Indeed two of his three species belong 

 to the latter genus ; so that the name Hypolytrum ought to have been 

 applied to the species in which the squamulte are ijarallel to the scale. 

 HypseU'ptum of Vahl {Enum. 2. p. 2S3f) appears to be identical with 

 Richard's genus, including both Hypolytrum and Lipocarpha. Hypae- 

 lyptum of R. Broxvn, prodr. 1. p. 219, (wlio quf tes Vahl, 1. c;) is pre- 

 cisely Lipocarpha of Nees ab Esenbecli, and this most profound botanist 

 expressly states that Sclianus ncmorum, Vahl, Scirpus anomalus, Rett., 

 S. hromeli(efoUus, Rudgc, and other unpublished species, having the 

 squarnulffi (" valvulae perianthii") lateral, with a very different habit from 

 Hypaelyptum, constitute a proper genus. This genus is the present 

 Hypolytrum, from which we must exclude, however, S. hromellerfolius, 

 Rudge, which is the Dvplasia Kerat^folia, Rich. Beera of P. de 

 Beavois, (in Lestih. ess. Jam. Cyp. p. 43. no. 57) seems to be scarcely 

 distinct from Hypolytrum of N. ab Esenb. Indeed the two genera are 

 united by the latter botanist.
