POTATO FAMILY—PHLOX FAMILY 25 
BUFFALO BuR SOLANUM BOSTRATUM 
Plate 19, fig. 4 
The yellow flowers of the Buffalo Bur are similar to those of its 
near relative, the potato. They grow on bushy plants, [-3 ft. high 
and are found along roadsides, in fallow fields and pastures at 4000- 
6000 ft. They bloom throughout the summer and the prickly pods are 
found along with the flowers. The common name refers to the prickles 
on pod and stem, and the specific one to the curious beak of the flower. 
The Buffalo Bur is an annual and hence it can be easily gotten rid of 
by cutting or burning. 
MORNING GLORY FAMILY

Plate 19, fig. 2 
The bushy form of this plant makes it a very strange Morning 
Glory in looks, but when in bloom the flowers are characteristic, open- 
ing in the morning and closing and withering later in the day. The 
large pink or red flowers cover the bushes with a riot of color during 
the summer. The bushes grow to a height of 2-5 ft. and possess huge 
roots, some of them attaining the size of a man. They are found on 
plains and foothills and in sandhills at 3000-6000 ft. The Bush Morn- 
ing Glory is highly ornamental and should be in cultivation.
