some small Umbelliferce, among which Cymopteriis inon- 

 taaus may be noted. Toward the end of the month a few 

 more begin to appear on the plains and in the foot-hills, 

 all of which possess either large, fleshy, perennial roots, as 

 Leucocrinum uiontaniini, Museniian trachycarpnm and 

 Peucedaaiun mmdicaule, or else they have large woody 

 subterranean stems from which spring the small leaves 

 and numerous flowers that spread out in dense mats or 

 cushions upon the cold soil. Such are Astragalus spatii- 

 latus and Astragalus sericoleiicus. Among the rocks in 

 sheltered nooks are also two Mcrtensias, lanceolata and 

 alpina. With the advent of May, or sometimes earlier, 

 the little Drabas, glacialis and alpina tinge the naked 

 rocks with yellow. In the moister canons our earliest 

 Buttercup, Rannncnlus glaberrinius, and the Wind-flower, 

 Anemone patens Nnttalliana, are found. 



Very slowly through May, for cold days and snow- 

 storms are far from rare, the number grows so that the 

 diligent observer may find several score. From this time 

 on the forms crowd upon each other in rapid succession 

 and one soon loses track of the order of their coming. 

 June is the floral month of the plains, July of the lower 

 mountains and August is the month of months in the high 

 altitudes. September has something of worth everywhere 

 and a few forms linger late into October. 



BOTANICAL WORK IN THE STATE. 



So far as I have been able to learn there are no other 

 workers in systematic botany in the state, nor are there 

 any other herbaria, public or private. On this account I 

 have been unable to make comparison of our specimens 

 with those from other localities in the state.
