MELANTHACE/ FROM THE GENETIC STANDPOINT. Lon 
occurs in North and South Carolina, and is tall rather than dwarfed, forming 
in this respect a transition to the genus Triantha. But it has neither the 
arrangement of the flowers in threes nor the scabrous pubescence on 
the stem characteristic of Triantha.

The genus Triantha, which contains the above five species, is properly 
separated from Tojieldia on account of (1) the scabrous pubescence, (2) the 
flowers in threes, and (3) the caudate seeds. The two western species, 
T. occidentalis and T. intermedia, should be included in this genus, since 
they have these three characters. 
In this connection the case of Tofeldia glabra is of very much interest.
