38 REPORT OF THE SECRETARY. 



to 1856, by Mr. Charles Wright, an accomplished botanist, who accoiu-' 

 l^auied the Mexican boundary commissioners in their surveys, and who 

 has also made extensive botanical explorations in Cuba. There has 

 been no full report of the collections made on the North Paciiic expedi- 

 tion, though many of the new species have been published by Dr. Gray. 



3. The naturalists who accompanied most of the surveying parties 

 which made explorations for the route of a Pacific Eailroad collected 

 large numbers of plants, manj- of which Avere new to the botanist, and 

 have been described in the published reports of these explorations. 



4. Collectious made in the Mexican boundary survey by Dr. C. C. 

 Parry, Dr. J. M. Bigelow, Mr. C. Wright, Professor George Thurber, 

 and Mr. Arthur Schott, are among the most extensive and valuable 

 portions of the herbarium. A full account of them, by Drs. Gray, Engel- 

 mann, and Torrey, is contained in General Emory's report. The Cac- 

 tacete, and one or two smaller orders, were described by Dr. Engelmann ; 

 the Compositic, Scrophulariaccic, and one or two other orders, by Dr. 

 Gray ; and the ferns, with their allies, by Professor D. C. Eaton. The 

 remaining Cryptogamia are not included in the report, but most of the 

 new or rare ones have been published elsewhere. The grasses were to be 

 described in a separate memoir by Professor Thurber. 



5. Large additions have been made to the North American portion of 

 the herbarium, chiefly from within the limits of the United States and 

 Territories, by contributions from the following places : New England, 

 by Mr. Oakes, Dr. Gray, Professor Tuckermau, S. T. Olney, esq.. Pro- 

 fessor D. C. Eaton, and others; New Jersey, by Mr. C. E. Austin, Pro-

 LeEoy, Clinton, Torrey, and many others; Pennsylvania, by Dr. Dar- 

 lington, and Professor Thos. C. Porter ; North Carolina, by Pev. Dr.

 Southern States;) Alabama, by Professor Winchell; Kentucky, Dr. Short, 

 and Mr. Sullivant ; Texas and New Mexico, Messrs. Fendler, Ervend- 

 berg, and others, besides what the botanists collected in the Mexican 

 boundary survey ; Pocky Mountains, Dr. Parry, Captain Macomb, 

 and Dr. Newberry ; Oregon, Mr. Geo. Gibbs, and others ; Nebraska, 

 Dr. Hayden; Nevada, Mr. Stretch; California, Dr. H. M. Bolander, 

 General Fremont, Miss Davies, Th. Bridges, Mr.E. Samuels, Dr. Torrey, 

 and many others ; Colorado, Dr. Anderson, Fremont, and others. Besides 

 these principal sources of United States plants, very many specimens 

 have been received from other j)laces and persons, which we have not 

 space to enumerate. From British America, especially the sub-arctic 

 portions, Dr. Kennicott, and officers of the Hudson's Bay Company have 

 furnished specimens. Of foreign plants, besides those collected in the two 

 United States exploring expeditious already noticed, the herbarium con- 

 tains valuable and large contributions from Japan, Mantchuria, China, 

 etc., from Professors lieigel and Maximovitch, of the Imperial Academy 

 of Science of St. Petersburg, and the Imperial Botanic Garden : A
