The Genus Leianthus was founded by Grisebach upon 

 the Lisianthus longifolius, and with that plant our present 

 one is undoubtedly a congener, and remarkable for the 

 colour of the flower, approaching- more nearly to black than 



any 



* So named by Geisebach from *•«*, smooth, plane, and «»&*, *#°*"i 

 probably on account of the even or regular corolla, as distinguishing tne 

 Genus from Lisianthus.
