is not flat on the one side, with a tubercle on the other, 
but presents a tubercle, which is internally spongy, on 
both sides; nor is it half so large as that of V. crispa. 
The leaves are not nearly so fleshy.

the scape usually one pair of floral leaves, from the 
axils of each of which arises a head of flowers in addition 
to the terminal one; and these three heads are often so 
closely approximated as to appear but one. This plant 
does not perhaps belong to the genus Betchea: its fruit is 
not triquetrous, nor is the limb of the calyx 1-toothed and 
deciduous. Still, although the 1-celled fruit is far from 
mature, there is not the least appearance of the urceolus 
of the calyx being toothed, or becoming ultimately plu- 
mose, as in Valeriana. Viewing, then, Betckea, depending. 
as a genus on its unilocular fruit, without any trace of 
abortive cells, and on the limb ofthe calyx not becoming 
pappose, we prefer uniting this species to it, to consti-
