The following Scrophulariaceae : Melasma (6 species), Striga (6 species), 
Cycnium (3 species), Uhamjihicarpa (2 sj^ecies), Harveya (5 species) (hemi- 
parasitic root parasites). 
A few orchids are saprophytic or nearly so. 
The total number of Heterophytes is cir. 40. The total numler of 
species dealt with (including Heterophytes) is cir. 3074. 
Since Heterophytes were not included by Eaunkiaer as a separate class, 
we may neglect these and reckon, for statistical purposes, the total number 
of species included in the analysis as being 3034, distributed as follows :
