JOURNAL OF THE NEW YORK BOTANICAL GARDEN. PLATE (224 
On edge of prairie west of Lake George, Florida, December 6, 1918.—Opuntia 
ammophila with stout trunk and many branches. Notice the abundant long and 
slender spines and the small fruits. This is the most abundantly fruited prickly- 
pear in Florida, except O. Dillenii. Owing to the lateness of the season most of 
the berries have fallen. In spite of the vicious armament the half-wild cattle of 
the region browse on the young joints of these large plants which often grow in 
quite extensive colonies.
