This genus is remarkable as being the only herbaceous one among the tropical 

 section of this family. It is very peculiar in habit, consisting of low, large-leaved, 

 almost stemless plants, which are natives of the southern parts of both peninsulas.

A good deal like the last, but easily distinguishable by its less membranous leaves, 

 which are more narrowed at the base, by its much shorter racemes, which are often 

 quite concealed by the sheathing bases of the leaves, and by the much smaller 

 flowers. There is an extensive series of specimens of this species in the Hookerian 



Herbarimn, from which we 1 rn that it flowers in its first year, and that in young
