Ocs. I have not had an opportunity of examining this plant. 
If it really belongs to the tribe Scirpece, its place is next to 
Malachochcete, N.ah E., which difters in the scales of the pe- 
rigynium being 5 or 6, instead of 2. It may, however, be 
more nearly related to the Hypolytreae, if not a species of Hy- 
polytrum* itself.

* The genus Hypolytnnn, as characterized byEicharci, inchided also 
what is now called Lipocarpha. Indeed two of his three species belong 
to the latter genus ; so that the name Hypolytruni ought to liave been 
applied to the species in which the squaniulse are parallel to the scale. 
Hypsp-lypture of Vahl {Eman. 2. p. 283t) appears to be identical with 
Richard's genus, including both Hypolytruni and Lipocarpha. Hypae- 
lyptum of R. Broun, pradr. 1. p. 219, (who quotes Vahl, 1. c.) is pre- 
cisely Lipocarpha of Nees ab Esenbeck, and this most profound botanist 
expressly states that Schaiius vemoriim, Vahl, Scirpus anomalus, Retz., 
S. bromelioffolius, Rudge, and other unpublished species, having the 
squamulffi (" valvulas perianthii") lateral, with a very diflerent habit from 
Hypaelyptum, constitute a proper genus. This genus is the present 
Hypolytrum, from which we must exclude, however, S. bromditrfolius, 
Rudge, which is the Dlplasia Keralcefolia, Rich. Beera of P. de 
Beavois, (in Lestih. ess. Jam. Cjjp. 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.
