2. CAREX. Linn. 
1. C. hebecarpa; culmo triquetro scabriusculo, foliis margine scabris, bracteis foliaceis 
elongatis inferiore vaginato superioribus evaginatis, spicis sterilibus 2 vel 3 sessilibus, 
squamis oblongo-lanceolatis fertilibiis cylindraceis acutis superioribus subsessilibus infima 
pedunculata, pedunculo vagina duplo longiore, squamis subulatis fructum lanceolatum 
striatum hispidum rostro bifido glabro aequantibus, stigmatibus 3. 
Hab. Conception. — Very closely allied to C. riparia, fl’oni which it differs by its narrower scales and 
much more attenuated fruit, Avhich is covered with short psipiUse or scabrous points. Of the sterile spikes, 
the lower scales are oblong and mucronate, hut the membranous portion becomes shorter and the mucro 
longer towards the extremity of the spike, so that at the top the scales ai’e nearly as in the fertile spikes.

Hab. Valparaiso. — Polypogon australe of Brongniart, in Duperrey’s Voy. p. 21, appears to be only a 
variety of the present. 
4. CALOTHECA. Beam. 
1 . C. stricta ; culmo scabriusculo, foliis convolutis scabris, panicula subsimplici coarctata, 
spiculis ovatis erectis 7-floris, glumis calycinis ovatis rotundatis 3-5-nervibus glabris corol- 
linis glabris nitentibus, exteriore duplo majore subrotundata acutiuscula mutica. 
Hab. Conception. — This is closely allied to the C. rotundata, Roem. and Schul. {Bromus rotundatus, H. 
and B.) and also to DesvaiLx’s Cliascolytrum erectum, whose panicle has the branches simple. The species 
referred to these two genera by Roemer and Schultes, are in great confusion. Thus, their Calotheca rotun- 
data is a Cliascolytrum. The Cal. brizoides, Beauv., is not the plant of Desvaux, or of Roemer and Schultes,
