In the opinion of the writer, Wallich, No. 1717, is not 
a variety of this species, but is to be referred to 
Polygonum lapathifolium Linn. Wallich’s sheet shows 
no more canescence than many examples of Polygonum 
lapathifolium from Burma and elsewhere, which show 
all stages from a quite evident tomentum on the lower 
surface of the leaves to leaves quite glabrous except for 
the scabrid midrib and margin; in its annual habit, its 
glandular peduncles and perianth, Wallich’s plant in no way 
differs from Polygonum lapathifolium Linn.
