Sciachphjllinn differs from Hej^tapleurnm and Jgahna by its se- 
veral free styles, from Fatsui by its strongly-ribbed fruit, and was 
founded by P. Browne on a Jamaica tree witb digitate leaves, um- 
bels arranged in racemes, a 5-tootlied calyx, a corolla composed of 
5 petals closely united into a calyptra, 5 stamens, 5 styles, and a 5- 
celled ovary. Euiz and Pavon afterwards named tlie genus Jctino- 
phyllifm, and added several Peruvian species, several of which, liow- 
ever, differ from the original type of the genus in having double the 
number of stamens and petals, and the petals so closely united that it 
is impossible to trace their imlividual limits, and the corolla might be 
appropriately described as monopetaloiis. At one time I thought it 
possible to iestii:3t the genus Scladoplryllum to those species, the corolla 
of which consists, apart from aU theoretical considerations, of one piece 
only ; and, on that ground, I proposed for the African species the name 
jistropanax ; but a close examination of all the matcriids at hand, en- 
closing the authentic specimens of Kuiz and Pavon, has convinced me 
that there is a gradual transition, from the Sciadophi/lla with free
