leaves obovate and tapering into a winged petiole, doubly 
incisely toothed ; the upper tri-multifid. The hispid pubes- 
cence of the stem is not appressed. ‘The foliage, the more 
slender spikes, and the much shorter fruit distinguish the 
species readily from V. stricta.

calycem equantibus.— Open woods at Sim’s Bayou, near 
Houston. May to July. Also, in Drummond’s Texan Col- 
lection, (Coll. 2, No. 221, and 3, No. 257.) Stems one to 
two feet high, simple or branched from the base, slender, 
pubescent when young, as well as the leaves and petioles, 
with scattered hairs. Corolla two inches long. Anthers some- 
what included; the lobes slightly mucronate at the base. 
Stigma a simple lamella, with a mere rudiment of the second 
lobe. —This well marked species differs from the rest of the 
genus in its inconspicuous bracts, and naked, more explicate 
inflorescence, which entitle it to the rank of a distinct sec- 
tion.
