BOTANICAL REPORT. 



i. Clematis ligusticifolia (Nutt. ! mss.) Torr. & Gray, 

 Fl. I, 9. 



Range of type: " Plains of the Rocky Mountains, in 

 open and in bushy places near streams." 



Near the head of Willow Creek, along the pools of the 

 interrupted creek. The specimen is a female plant, with 

 akenes partly grown; the leaflets of the upper branches 

 are almost entire, lanceolate-acuminate, varying in width 

 near the base from 1 cm. to 4 mm. It shows the effect 

 of its desert environment in its sparse, little dissected 

 foliage and narrow leaflets; young parts silky-canescent, 

 older parts nearly glabrous. 



2. Aquilegia micrantha Eastwood, Proc. Cal. Acad. 

 Sci., 2d Ser., iv, 559, t. 19. 



Type locality : ' ' Moist bench under the cliffs near Bluff 

 City." 



The specimens were collected at the type locality and 

 also near the head of Willow Creek, with the same pe- 

 culiar environment. There is considerable variation in 

 the size and color of the flowers, length and uniformity 

 of the spurs and the character of the foliage. The 

 variations are due to the amount of moisture, which is 

 not uniformly distributed under the cliffs, but oozes out 

 more in one place and less in another, perhaps not a yard 

 away. One plant collected in a dry place has the leaves 

 with ultimate divisions, from 2-5 mm. wide, clustered at 

 the base of the stem; whole plant very viscid. The 

 sepals vary from cream-white to rose color; spurs are 

 sometimes all uniform in one flower and diverse in another
