106 ILLUSTRATIONS OF INDIAN BOTANY. 
Remarks on Genera anv Species. The genera of this order are few, but require mucl 
nicety, and attention to minute organs, for their accurate discrimination ; the structure of the 
ovary, which in most is very small, and the number and positionor‘tte ovules in its cells, affording 
the marks on which the greatest dependence can be placed, accordingly form the basis of our 
characters. The following synoptical table which I extract from our Prodromus will place this 
in aclear point of view. It contains an analysis of all those having stamina twice as numer- 
ous as the petals and a definite number of ovules in each cell of the ovary.
