PREFATORY NOTE. 



To the collections of Palmer, Pringle, and Kelson, upon which the 

 first part of this paper was chiefly based, is to he added my own collec- 

 tion made in Mexico in 1897. This collection embraces 2,569 numbers 

 (1,200 to 3,768, inclusive) and comes from fifteen States and Territories, 

 but chiefly from Sinaloa, Territorio de Tepic, Durango, Jalisco, and 

 Zacatecas. I was four mouths in making this collection (June to Sep- 

 tember), and I was especially fortunate in duplicating at the type local- 

 ities many species which have only once before been collected. This 

 was particularly true of some of Palmer's species from Guaymas and 

 La Paz, Seemann's species from the Sierra Madre, Hartweg's species 

 from Bolanos and vicinity, and Palmer's and Pringle s species from 

 Guadalajara and vicinity. The collection is especially rich in Umbel- 

 liferae, among which an unusual proportion are un described ; in Agave, 

 of which genus it contains 75 sheets, while in the National Herbarium 

 there are only 38 sheets from Mexico ; and in Orchidaceae, with G7 sheets, 

 Compositae, with 271 sheets, and Quercus, with 47 sheets. 



Besides the herbarium specimens, a very respectable collection of 

 roots, bulbs, seeds, etc., was sent to the Botanical Garden. 



Of these the following have flowered since arriving in Washington:
