Several of these are represented by a single species only, and 
none of them by more than five or six. Many of them are little 
very imperfectly. The principal point of general interest to be 
noted about them is that they are scattered through the whole 
lace. : 
Sere type that influences most the general physiognomy 
of the vegetation is the Traveller’s Tree, Ravenala ma ariensis. 
It is allied to Heliconia and the Banana, and has a tall simple 
and a capsular fruit, with numerous small umbilicate seeds with a 
blue pulpy arillus. Dypsis is a palm alli moe
