These specimens seem to belong to the var. subminuta 
of Broth. & Dixon, the exothecal cells being mostly 20- 
30 4 wide. The leaf-points are rather broader and blunter 
than in any specimens observed from India. 
The separation of the above genus from Merceya seems 
to leave the American species Merceya latifolia Kindb. in a 
rather anomalous position as it has, probably, as finely 
differentiated a border to the leaves as any of the known 
species and also a costa with a row of cells on the ventral 
side above the guide-cells.
