PROSPECTUS FOR THE COU.ECTION OF 1901. 



My botanical field work in the Rocky Mountain region, begun nine 

 years since, will be continued in 1901 and 1902, with better facilities and 

 under conditions otherwise more promising than heretofore. The speci- 

 mens will be of better quality. The determinations will be made by 

 those botanists who are most competent to deal with matter from the 

 West; thus making the collections authoritative, as representing in 

 herbaria the flora of the several regions explored. 



In 1901, the summer and autumn will be given to the field from Mar- 

 shall Pass eastward and south westward to the boundary lines of Colorado; 

 a field, as far as known, exhibiting many peculiarites as to plant genera 

 and species, and therefore of the highest promise. The ground will be 

 covered as carefully as possible, at all elevations, *. e. y from 4,000 to 

 13,500 feet. This will be our third and probably the concluding series of 

 our Colorado plants. 



It is purposed to begin, in 1902, the exploration of a still newer field, 

 that of the more westerly State of Nevada ; and several years may be 

 devoted to that field, prosecuting the work throughout many of its 

 isolated and almost or altogether unexplored mountain ranges, and to 

 the western and southern borders of the State. 



Subscriptions to all these series are now being received, and should be 

 registered as early as possible ; for the sets go out to subscribers in the 

 order of time recorded for the subscription, the fullest sets to the earliest 

 subscribers. Arrangements have been made whereby it will be possible 

 for any institution to obtain these sets. Correspondence is solicited. 



A few short sets of the collections by Baker, Barle and Tracy in 1898 

 are still available. One good set of the 1899 collection, but lacking the 

 grasses, sedges and rushes, though very rich in the new species, remains 

 unsold. Its price is $73. 



The distribution of mosses and liverworts from South America will soon 

 be made. These include many new species.
