If the species are classified according to their habit we find that 

 78 are climbers, 74 are trees that may exceed 30 feet in height, 20 are 

 small trees that do not exceed 30 feet, 48 are shrubs and 138 are her- 

 baceous, (treating as herbaceous species like Garica, Sccevola, Musa 

 Grinum, etc., and all Gryptogams except the two climbing ferns, Lygodium 

 and Acrostichum, scandens, which are here included among the other 

 climbers). But though as regards number of species herbaceous forms are 

 so largely represented they are as a matter of fact extremely inconspic- 

 uous, two-fifths of them being cryptogams and one-third of these beino- 

 marine. Nor, if we except the herbaceous climbers, which are here 

 dealt with along with the woody ones, and the species that occur on the 

 few bare grassy slopes, are herbaceous phanerogams more numerous than 

 herbaceous cryptogams. The most numerously represented herbs are 

 Andropogon contortus, Desmodium polycarpon, Besmodium triquetum 

 Vernonia cinerea, Blumea virens, the various species of Fimbristylis 

 Cyperus pennatus and polystachyus, Boerhaavia repens, Ischcemum muti- 

 cum, Thuarea sarmentosa. Herbaceous species that frequent deep
