rectly assigns it to Ipomoea ventricosa (Fl. 467. 1861), and, ex- 

 cept for the somewhat exaggerated size of the corolla, the plate 

 matches almost exactly specimens from Martinique, the type 

 locality of C. grandiflorus, recently collected by Duss under the 

 name of Ipomoea ventricosa. 



Ipomoea 



Upon the authority of Dr. Urban, the species described by 

 the writer as "Ipomoea Fawcettii Urban," is to be referred to 

 Convolvulus tenuifolius Vahl. Unfortunately Vahl's C. tenui- 

 folius was taken up in Ipomoea for Ipomoea quinata R. Br. to 

 which C. tenuifolius is referred by the Index Kewensis, but upon 

 what authority is difficult to imagine, since Ipomoea quinata is 

 an Old World species, and the type locality of Vahl's species is 

 given "Habitat in India occidentali." The proper nomenclature 

 of this species should be as follows: 



Ipomoea tenuifolia (Vahl) Kuntze, Rev. Gen. 446. 1891, as 

 to syn. Vahl only. 



Convolvulus tenuifolius Vahl, Symb. Bot. 3: $$. 1794. 



Ipomoea Fatvcettii Urban; House, Ann. N. Y. Acad. Sci.

 1908. 



Represented in recent collections only by the Jamaican 

 specimens collected by Harris {860^ 1904; fOOIO, 1907). 



The specimens referred to by the writer as ipomoea hirti 

 flora Mart. & Gal. and later described under that name, appar- 

 ently do not belong to that species. Hallier has identified Ipo- 

 moea hirtiflor a Mart. & Gal. with Jacquemontia lactescens Seetn. 

 (Thyella lactescens House), of Central America and Panama.
