The species is probably autoecious, although no pycnia or 
aecia have yet been seen. The collection by Baker is unique in 
producing a fusiform swelling of the stem full two inches long and 
twice the normal diameter of the stem. The uredinia have been 
rarely seen. It was detected in the phanerogamic herbarium of the 
N. Y. Bot. Garden, on the same host from Sierra de Anafe (Prov. 
Pinar del Rio), Dec. 1911, II, P. Wilson. The species is now first 
reported for the West Indies.
