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 Uniola mucron- 

 ata, Burm.) is an East Indian, not a South American plant; and Brornus brizoides, Lam., has an erect panicle 

 and glabrous glumes; it has, however, a lanceolate calyx, and seems to be a true Culotheca. Calotheca 

 elegans, Beauv., not noticed by other authors, is Chascolytrum subaristatum, Desv.

Hab. Valparaiso, (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 monoecious or poly- 

 gamous. The style is bipartite: the hypogynous scales with two acuminated points.

Hab. Conception. — As far as can be judged 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 Mr. Mathews. It seems to differ from the E. palustre 

 only in its rougher stems.
