when dry, verticellately branched; the secondary stalks longer, 
slender, also angular when dried, finely lenticelled as is also the pe-

short, 2 to 3 subverticellately branched, glabrous, ebracteolate; 
pedicels slender, 5 mm. long, whitish; calyx glabrous, the upper 
2 mm. broadly eup shaped and nearly twice as broad, white, seg-

brous on both sides; corolla broadly tubular, 6 mm. long, gla- 
brous except the puberulent upper side of the segments and the 
villose tube from the throat down toward the base, 3 mm. thick, 
similar in color; segments broadly orbicular, imbricate, straight, 
2 mm. across; stamens also 5, included, subsessilely attached 
1.5 mm. below the throat; anthers 1.25 mm. long, compressed, 
gradually tapering from the rounded or minutely auriculate base to 
the rather fine apical point; ovary glabrous, white, conically glo- 
bose, 1.25 mm. across; style whitish, slender, also glabrous, 2 mm. 
long; stigma much enlarged, 0.5 mm. long, ringed around the
