274 A NEW GENUS OF THE COMMELINACEAE 
extreme base and in the lower two-thirds of the inner face) with 
showy lavender-purple hairs, (b) the two postero-lateral densely 
bearded above the middle with a collar of short lavender-purple 
yellow-tipped hairs, (c) the two antero-lateral bearded below 
the middle on the posterior margin with a tuft of short lavender 
hairs, and (d) the anterior stamen glabrous throughout—anthers 
of the three anterior stamens oblong, these stamens being mani- 
festly larger throughout than the posterior stamens, the latter 
with orbicular anthers; ovary constricted in the middle, the 
stigma terminating a slender bent white style; capsule oblong, 
ong; seeds 3-3.5 X 2-2.25 mm., rounded at one end, 
) ear 
eccentric perforation containing the minute embryo; endosperm 
not continuous but separated by an obscure commissure on one 
side and bearing a group of low broad, tuberculate ridges radi- 
ating from the sides of the embryo cavity, where it comes through 
to the outer surface. 
In rich, moist, shaded soil of ravines and rocky hillsides of 
the Edwards Plateau, Texas; February to October, but princi- 
pally March to May. Original localities, according to Torrey: 
“shady woods on the Blanco, Comale, and other rivers, 
Texas; Wright, (No. 699.) San Antonio, Texas; Thurber.” 
A comparison of Torrey’s description with that submitted 
herewith will reveal several places wherein certain differences 
appear. These differences are: (1) in the height of the plant; 
(2) length of basal leaves; (3) number of flowers per raceme; 
(4) I can find no evidence of wings on the margin of the posterior 
filament and am at a loss to account for Torrey ’s mention of such 
structures unless he examined the filament in question only 
from the flat naked inner face of pressed material; (5) the ovary 
is uniformly three-celled with two superimposed ovules in each 
cavity, though failure of fertilization will of course cause abortion 
of any one or more of the six, with a consequent great variation 
in the appearance of the capsule; (6) the seeds, though super- 
ficially resembling those of Tradescantia, are different from any 
Tradescantia seeds I have examined in that the cavity containing 
the embryo extends entirely through the seed, the endosperm 
instead of being continuous around the embryo is separated by 
a commissure that extends to the embryo-cavity on one side, 
and the seeds of C. anomala are of greater size. Other points 
which are brought out in the description submitted herewith 
are not mentioned in that of Torrey.
