 flowers. 



The manner of dissemination is not definitely known for over 

 half the species. Three or four (the Baptisias and Psoralea 

 canescens) are tumbleweeds. About 23 others, mostly Composite, 

 have seeds or fruits transported by the wind. Thirteen, mostly 

 shrubs, have fleshy fruits, adapted to be eaten by birds. Only 

 four or five have barbed fruits. The Cupuliferae of course have 

 nuts which are supposed to be carried off by squirrels. In per-

haps a dozen species the seeds are scattered by elastic force, 

 which is either accumulated in capsules and legumes or actuated 

 by the wind or animals. 



The above list contains about 137 species belonging to 100 

 genera and 38 families. Only 16.4% of the angiosperms are 

 monocotyledons. As in dry sunny places throughout North 

 America, the Compositae are most largely represented, with 25 

 species, and Leguminosae next with 23 ; but this list contains 

 a larger proportion of the total Leguminosae of the region than 

 it does of Compositae. Grasses are not as numerous as one might 

 expect, but one species, Aristida stricta, is probably more
