The flowers are showy and when many on a vine are expanded 
at the same time form an elegant floral display; they appear more 
or less abundantly nearly throughout the year, and resemble those 
of the cypress-vine. 
It was first described as a distinct species from specimens collected 
by Charles Wright in western Cuba about 1865. On the Bahamas 
it was collected much earlier by Swainson, and thence, apparently 
erroneously, recorded by Grisebach (Fl. Brit. W. Ind. 472) as 
Ipomoea arenaria Steudel, a plant of Porto Rico, Hispaniola and the 
northern Lesser Antilles. Its occurrence in Florida was determined 
by J. K. Small and J. J. Carter in 1903. 
Our illustration is made from a plant collected on rocky hills near 
the city of Camaguey, Cuba, by N. L. Britton and J. F. Cowell, in 
April, 1912, which flowered at the New York Botanical Garden in 
November, 1914.
