Basin, and represents a further development of the tendencies already 

 evident in the material obtained by Judge Henderson's expedition. 

 The following scheme will indicate the general facts, as I understand 

 them: 



8. Botany — Account of Collections Made 



By Francis Ramaley 



No attempt was made to secure complete collections at the places 

 visited since members of the party were chiefly engaged in other work. 

 Some herbarium specimens were collected, representing the more com- 

 mon plants of typical localities. Notes were taken regarding the dis- 

 tribution of plants on mesas and in gulches. A general survey was 

 made to determine the places where further study should be undertaken. 



Collections were made as follows: (a) In a Cottonwood forest along 

 the St. Vrain Creek about a mile below Lyons, Boulder County — 75 

 numbers; (b) Fossil Creek, seven miles south of Ft. Collins, Larimer 

 County — plants of the ridge, 60 numbers, valley plants 51 numbers, 

 roadside plants — 35 numbers; (c) High plains and the bluffs border- 

 ing these about eight miles west of Pawnee Buttes in Weld County — 

 67 numbers; total 288 numbers. So far as possible the plants were 

 collected in duplicate and specimens sent to Professor Aven Nelson for 

 identification. In a few cases material was not in condition and could 

 not be identified with certainty. Most of it was satisfactory, and with 

 even the few specimens collected, a fair idea of the floral characters 

 of the country can be obtained. 



In general the plants are those characteristic of the eastern plains 

 region of the state, The climatic conditions are distinctly xerophytic, 

 hence dry-country plants^ are the rule except in river bottoms. Plants 

 of the pulse family are especially conspicuous in most of the dry locali-
