Gleason: Studies on West Indian Vernonieae 309 



Vernonia corallophila sp, nov. 



Stem erect, herbaceous, 4 dm. high, virgate, finely striate, 

 strigose-pubescent; leaves sessile, narrowly linear, rigid, revolute, 

 one-nerved, 1-3 cm. long, strigose-hispid and punctate above, 

 densely strigose-pubescent beneath; inflorescence cylindrical or 

 sparingly branched; heads n-flowered, in the axils of the upper 

 leaves or rarely 2 or 3 together on a short ascending lateral cyme; 

 bracteal leaves resembling the cauline, but reduced in size and 

 the upper barely exceeding the heads; involucre turbinate, 5-6 

 mm. high, its scales all straight, erect, very loosely imbricated, 

 strigose-pubescent, the outer subulate, the inner narrowly oblong, 

 long-acuminate; achenes pubescent, 2 mm. long; pappus nearly 

 white, the inner series 4-5 mm. long. 



Type, Britton 1939, from a coral limestone beach at the United 

 States Naval Station, Guantanamo Bay, Oriente, Cuba, March 

 17-30, 1909, deposited in the Herbarium of the New York Botanical 

 Garden. 



The species is readily distinguished by its slender virgate 

 inflorescence and small leaves from V. stenophylla with its long 

 leaves and divaricate inflorescence.
