ListANTHUs cusPrpATUs Bertoloni, Nov. Comm. Bonon. iv. 408, t. 38 
(1840). Lecanthus 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 Listanthus cuspidatus leads to the belief that it represents 
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 Z. 
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. isianthus nigrescens Hook. in Curt. 
Bot. Mag. t. 4043, would appear to be LZ. cuspidatus Bert.
