The only genus to which this one comes at all near in 
character is Lagetta, from which it is amply distinguished 
by the pentamerous flowers perfectly dicecious, and other —— 
characters, besides a very different habit. I havegreatplea- 
sure in dedicating it to the distinguished young artist who 
accompanied Sir Robert Schomburgk in his second expe- 
dition, and brought home a beautiful set of views of various 
palms and other trees in their natural stations, besides pes 
valuable botanical drawings.

number, and possibly gathered from the same bush, but the fo- 
liage and branches are so very different as to leave it doubt 
whether they do not belong even to a distinct species. - we
