E. L. EKMAN, WEST INDIAN VERNONI^. 17 



this is the true V. Wrightii Sch.-Bip., as shown by the descrip- 

 tion and the handwriting of Schultz-Bipontinus. Gri- 

 SEBACii, in his Cat. Plant. Cub., p. 144, appHes the name 

 of V. Wrightii to the phmt generally numbered 1309, which 

 is V. leptoclada Sch.-Bip. Not accepting this plant as a 

 species, he cites it as a form of F. arhorescens Sw., though 

 maintaining the binomial writing (»F. Wrightii ScH., forma 

 foliis angustioribus subtus tomentosis, capitulis folio florali 

 multo brevioribus»). He does not mention anything about 

 F. leptoclada Sch.-Bip. Gleason, who has read the descrip- 

 tions of ScHFLTZ-BiPONTiNUS, but not discovered the mys- 

 tery of the interchanged labels, in the »Revision » assigns cor- 

 rectly F. Wrightii Sch.-Bip. to his Fruticosce (i. e. his Sagrce- 

 ance), though as a synonym of F. Sagrceana DC. He applies, 

 further, the name of F. leptoclada to the plant which in fact corre- 

 sponds to F. Wrightii. The true F. leptoclada Sch.-Bip. he refers 

 to F. gnaphali folia A. Rich., and consequently describes the 

 genuine F. ghaphalifolia, which thus had no name at its dis- 

 posal, as a new species, F. suhlanata Gleason. His remarks 

 on F. gnaphali folia A. Rich, read as follows: »Vernonia Wrightii 

 Griseb. 1. c. ; Not F. Wrightii Sch.-Bip.», and further: 

 »Wright's collection, 1309, included two species, one a form 

 with broad smooth leaves, F. Sagrceana DC, and the other 

 with tomentose leaves. The first was taken by Schultz 

 as the type of his F. Wrightii. Grisebach, apparently consid- 

 ering that the number included but one species, published 

 the name for the second form, thus introducing the sjtio- 

 nyms cited above». Evidently, this is an attempt of Glea- 

 son to explain the lack of harmony found between the 

 descriptions of Schultz-Bipontinus and the plants cor- 

 responding to them according to their numbers. In work- 

 ing out his »Studies» he had learnt that his F. suhlanata 

 is identical with F. gnaphalifolia A. Rich. Thus his V. gna- 

 phali folia had no name, and consequently he names it F. 

 neglecta Gleason, creating in this manner one synonym more 

 for the true F. leptoclada Sch.-Bip. Still believing that this 

 species belongs to the Sagrceanoe, he identifies with it Shafer 

 n. 8145, a genuine F. Wrigthii Sch.-Bip. Another plant, 

 Shafer n. 7738, he refers to F. Wrightii, though with some 

 reservation. However, it differs from the genuine F. Wrightii
