Lisianthus cuspidatds Bertoloni, Nov. Comm. Bonon. iv. 408, t. 38 

 (1840). Leianthus cuspidatus Griseb. in DC. Prod. ix. 82 (1845). 

 This species is reduced to a synonym of Leianthus nigrescens (Cham. 

 & Schlecht.) Griseb. by Hemsley, Biol. Cent. -Am. Bot. ii. 345 (1882) 

 and of Lisianthus nigrescens Cham. & Schlecht. by Miss Perkins in 

 Engl. Jahrb. xxxi. 493 (1902). An examination of Bertoloni's excellent 

 plate of his Lisianthus cuspidatus leads to the belief that it repre-<>nts 

 a species markedly distinct from L. nigrescens. "Conspicuous differ- 

 ences are to be found in the following features. In L. cuspidatus the 

 leaves are narrowed to a subcuneate base, the corolla is much more 

 deeply lobed, the lobes distinctly surpassing the pistil, while in L. 

 nigrescens the leaves are rounded to a somewhat amplexicaul base 

 and the corolla-lobes are only 4-11 mm. long being somewhat over- 

 topped by the stigma. A specimen, collected in the Sapoti Barranca 

 near the City of Guatemala by Sutton Hayes, July, 1860, and now in 

 the Gray Herbarium, corresponds in all respects to the plate of Berto- 

 loni, and fully justifies the separation of the species. The lobes of its 

 corolla are 1.7 cm. in length. Lisianthus nigrescens Hook., in Curt. 

 Bot. Mag. t. 4043, would appear to be L. cuspidatus Bert.
