portion in which the several orders are represented in the collection 

 is somewhat remarkable. Of the 415 species, one fourth are equally 

 divided between the Gru mi 'nece (50) and the Compositce (50). Another 

 fourth includes only the four orders Leguminosce (44), Euphorbiacece 

 (32), Malvaceae (17), and Solanacece (15). These are followed by the 

 Ngctaginaceoe (15), Convolvidacece (13), Asclepiadacece (10). and 53 other 

 orders with still fewer species. The important orders lianunculacece, 

 Rosacece, Saxi'fragacece, Umbelliferce, Ericaceae, Ouptdiferce, Coniferce, 

 and Orchidacece are wholly unrepresented. Excluding the Cypera- 

 ccce and Graminece, there are only five endogenous species in the entire 

 collection. 



For the determination of the species the Cyperaceae were referred 

 to Dr. N. L. Britton, Curator of the Torrey Herbarium, the Gra- 

 mine<e to Dr. George Vasey, Botanist of the Agricultural Department 

 at Washington, and the Filices to Prof. Daniel C. Eaton. Special 

 acknowledgment is also due to Prof. Daniel Oliver, of the Kew 

 Herbarium, for suggestions respecting the relations of a few of the 

 more difficult species in other orders.
