This autoecious species possessing pycnia, aecia, uredinia, and 
telia is probably rather common throughout the West Indies, as 
well as northward and southward. It has been reported from 
Jamaica, Porto Rico, St. Croix, and the Bahamas. The aecia, 
which are not uncommon, usually occupy the under surface of all 
the leaves of erect and somewhat drawn and etiolated shoots. 
The uredinia of Charles Wright's collection no. 720, reported in the 
Cuban Fungi under the name Trichobasis euphorbiaecola B. & C., 
appear to be on Chamaesyce hirta, judging from the hairs and 
serration of the fragment of leaf seen from the Herb. Curtis, 
kindly transmitted by Dr. W. G. Farlow.
