LESCAILLEA EQUISETIFORMIS Griseb. 
This monotypic genus of Compositae was rediscovered on the 
southern slope of Cajalbana in the province of Pinar del Rio, 
Cuba, by Brothers Leon and Charles on April 6, 1915. The — 
genus has hitherto been imperfectly known, as it was represented 
in this country only by a fragment at the Gray Herbarium, 
collected by Charles Wright in western Cuba. Lascaillea is a 
woody vine related to Porophyllum. The leaves are reduced to 
small scales, the plant resembling certain species of Ephedra 
much more closely than it does any Eguisetum.
