afterwards, that there is no essential difference between the East Indian 
and American variety. The form with naked leaves from Busna can 
not be regarded as a peculiar variety, since there are sometimes in the 
same specimen covered and uncovered leaves. The length of the seed-

The normal form is peculiar to the East Indies; but a variety, almost 
entirely agreeing with the var. 8 gracilescens, is also a native of Egypt
