Amorphophallus leonensis was discovered in Sierra 
Leone by Dr. Afzelius, afterwards Professor of Botany at 
Upsala. It was first introduced into Europe by Van Houtte 
in 1845, Tubers were sent from Sierra Leone to the Royal 
Gardens, Kew, by Mr. Walter Haydon, Curator of the 
Botanic station in that colony, early in 1899, which 
flowered in a tropical house in March of the same year, 
and matured their leaves in the following May. It has 
also been collected in Senegal and Gambia. Dr. Masters 
describes four varieties of it as occurring in cultivation, 
namely, a. spectabilis, in which the petiole is marked with 
obscure Jinear-oblong spots; 8. elegans with a green 
petiole, bipinnatisect Jeaf-segments, the ultimate of which 
are very narrow, and y. /afifolia, in which the petiole is
