H a b . Couception.—Very closely allied to C. riparia, fi-om wliicli it differs by its narrower scales and
much more atteuuated fruit, nhich is covered with short papill® or scabrous points. Of the sterile spikes,
the lower scales are oblong and mua-onate, but the membranous portion becomes shorter and the mucro
longer towards the extremity of the spike, so that at the top the scales are nearly as iu the fertile spikes.

1. C. stricta; culmo scabriusculo, foliis convolutis scabris, panicula subsimplici coarctata,

H a b . Conception.—This is closely allied to the C. rotundata, Rcem. and Schul. (Bromus rotundatis, H .
and B.) and also to Desvaux’s Chascolytrum 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 Chascolytrum. The Cal. brizoides, Beauv., is not the plant of Desvaux, or of Roemer and Schultes,
m c e s.] 01
but is the Chascolytrum erectum of Roem., and SchuL Even the two other synonyms, reduced by these
authors to C. brizoides, cannot belong to it; for the Briza mucronata, Lam. (founded on the XJniola mucrcm-
ata, Biu-m.) is an East Indian, not a South American plant; and Bromus brizoides, Lam., has an erect panicle
and glabrous glumes; it has, however, a lanceolate calyx, and seems to be a true Calotheca. Calotheca
elegans, Beauv., not noticed by other authors, is Chascolytrum subaristatum, Desv.

H a b . Valpai-aiso, (sent also by Mr. Bridges.)—This we have the authority of Mr. Cruckshanks for
stating to be the plant of Molina: there is, however, only one flower in each spikelet, instead of three, as he
and Poiret assert it to have; nor can we discover any essential difference between it and the Peruvian plant
of Kunth; but this last we only know from his description. Our plant has the flowers monCBcious or polygamous.
The style is bipartite: the hypogynous scales with two acuminated points.

H ab. Conception.—As fiir as can be judg-ed from the descriptions of E . pratense of Ehrh., our plant
is the same species. The specimens are from 4-5 inches to a span long, much branched at the base. We
have the same species from Valparaiso, gathered by Mi-. Mathews. It seems to differ from the E . palustre
only in its rougher stems.
