The African specimens, which are very uniform, have rather larger leaves, 
capsules and seeds than the Asiatic and Australian plant, and on this account have 
been treated as belonging to a distinet variety both by Beille and, at a later date, by 
Pax and Hoffmann. Except as regards size, however, the African plant does not in 
any way differ from the Asiatic one and some of the Indian specimens are as large as 
many of the African ones.
