HARRISIA. 



153 



Found on Hammocks, Keys of Florida, and southern mainland coast. Type from 

 between Cape Sable and Flamingo, collected by John K. Small, November 29, 1916. 



The species is dedicated to Charles Torrey Simpson, naturalist, long resident in Florida. 



Flowers of a plant from Pumpkin Key, grown at the cactus garden of Mr. Charles 



Deering, Miami, Florida, and at the New York Botanical Garden, have the flower-tube 



little, if any, longer than the limb ; the 

 stems of this plant and its fruit are not 

 different from those of the type, but 

 are smaller, about 2 meters high. 



Figure 223 is from a photograph 

 taken by Mr. C. L- Pollard on Key 

 Largo, Florida.
