A recast of the genus, with descriptions of C, Palmeri, from 

 Southern Cahfornia (E. Palmer, 1875, No. 42), C Parryi, de- 

 scribed from specimens cultivated at Calistoga, Cal, collected by 

 Dr. Parry under No. 33, in 1881, and C. impresses from Santa 

 Barbara County, Cal. C, eglandiilos7ts is C. divaricatus, var. 

 eglajidulosiis, Torrey, and C, parvifolitis is C. mtegemmus, var. 

 parvifolius, Watson. C. floribundiis, Hook., and C. Lobbianus, 

 Hook., are provisionally referred to C. dentattis, T. and G., as 

 sub-species, a rank, which we venture to hope, Professor Trelease 

 will not maintain in his final treatment of the genus. Thirty-two 



species are recognized, twenty-five of them Euceanothus, the re- 

 maining seven forming the section Cerastes, having the fruitmg 

 carpels each with a dorsal horn. N. L. B-

Of these papers the one purely botanical is on the Forest Flora 

 of the Rocky Mountain Region, by George B. Sudworth, contain- 

 ing an analytical key, and descriptions of eighty-eight species of 

 trees and a list of shrubs. To those more interested in the econ- 

 omic questions which are assuming such serious dimensions m 

 our forestry administration, this voluminous report will be of 

 great value. .

 A list culled from Mr. Hemsley's Central American Botany. 



1,218 species are certainly attributed to Costa Rica, while those 



whose range would indicate that they should grow within the 



republic increase this number to 3,386.
