retrorsely pilose, often scarcely a foot high; leaves remote, 
ovate-lanceolate, acute, with the nerves parallel to the in-

wide; calix very hispid, and pungently awned, about 
1-third the length of the corolla; corolla uniformly whitish 
or reddish, externally covered with soft hairs, about an 
inch long, tube long and slender, funnelformly inflated 
above; upper lip arched and crenate; lower lip obtusel y

402. *SYNANDRA.+ 
Calix 4-cleft! segments uneqnal, subulate, 
connivent to one side. Upper lip of the corolla 
entire and vaulted; the lower obtusely and un-

Perennial? and herbaceous; leaves cordate-ovate, those 
of the stem sessile and amplexicaule; flowers without 
bractes, sessile, solitary; calix small, embracing the atten- 
uated tube of the large corolla which partly resembles

S. * grandiflora. 
Descatpr. Stem usually simple, about a foot high, 
nearly smooth, irregularly grooved, and partly’ terete. 
Leaves a little hirsute on the upper surface, lower ones

plexicaule, cordate-ovate, acuminate, obtusely dentate, 
often dilated at the base, diminishing upwards. Flowers 
often commencing with the second or third pair of leaves, 
solitary and sessile. Calix about 2 lines fs , densely 
and softly pilose, cleft about half-way down into 4 conni-
