2208. Hitchcock, A. S., and Agnes Chase. Revisions of North American grasses. Con- 

 trib. U. S. Nation. Herb. 22: 1-77. PI. 1-34, fig. 1-20. 1920.— Under this title are published 

 revisions of four genera of grasses of the tribe Paniceae. The first, by A. S. Hitchcock, treats 

 of the North American species of Ichnanthus. Ten species are described, all but one illus- 

 trated by photographs of specimens. The second, by the same author, is a revision of the 

 fifteen known species of Lasiacis, all American, each of which is represented by a photo- 

 graph of a specimen. One new species, Lasiacis leptostachya Hitchc. from Nicaragua, is 

 described. The third paper, by Agnes Chase, discusses the North American species of 

 Brachiaria, a genus which, unlike most of the Paniceae, belongs primarily to the Old World. 

 Six species are described, each illustrated by figures showing part of the inflorescence, anterior 

 and dorsal views of a spikelet, and the fruit. One new species, Brachiaria ophryodes Chase, 

 from Mexico, is described, and the following new combinations occur; Brachiaria Gilesii 

 (Benth.) Chase, B. miliiformis (Presl) Chase, and B. ciliatissima (Buckl.) Chase, only the 

 last referring to a North American species. The fourth paper, by Mrs. Chase, treats of the 

 North American species of Cenchrus, 13 species being described and illustrated by figures -of 

 the burs and of the spikelets. The name Cenchrus carolinianus Walt., which has figured in 

 the literature for some years, is regarded as unidentifiable. — S. F. Blake.
