same root cluster, terete, green, ascending, occasionally branched 
below the middle but usually toward the top, varying 1 dm. 
to 1 m. in height, base of stem ligneous; roots ample, fibrous; 
branches few, ascending, sparingly rebranched, crookedly vir- 
gate, latericius pubescent especially on the terminal or young 
portion. Leaves soft membranous, horizontally spreading, dark 
velvety green above, glaucus green beneath, pubescent especially 
on the lower surface, greatly varying in size, the normal blades 
1 dm. long by 4.5 cm. wide across the middle or a trifle below it, 
oblong or ovately oblong, entire, obtuse or bluntly acute at apex, 
roundly obtuse at the base or subcuneate, oppositely scattered 
but usually crowded toward the top, light purple tinged in the 
dry state especially on the lower side; petiole 1 to 3 cm. long, 
latericius pubescent; midvein conspicuous from beneath, the 
11 to 14 lateral pairs subparallel and ascendingly curved, retic- 
ulations obsolete; stipule pubescent, the broad basal portion 
2.5 mm. long only, abruptly terminated by a 5 mm. long very 
slender point. Peduncle usually solitary, in the fruiting state 
3 to 5 cm. long, erect, terminal, similarly pubescent, subtended 
by stipular bracts; branches at the top mostly, 3 to 5, circinately- 
recurved, pale green except the pure white flowers, purplish tinged, 
all pubescent; pedicel hairy, about 2 to 3 mm. long, subtended 
by one or more unequal linear similarly hairy bracts; calyx el- 
lipsoid, 3 mm. long, crisply pubescent, the upper one third com- 
posed of 5 linear hairy teeth; corolla 7 mm. long, sparsely pu- 
bescent on the outside except at the glabrous constricted base, 
the throat region on the inside densely woolly ;segments 5, ovately 
obtuse, glabrous on the upper side, 2 mm. long; stamens normally 
5, inserted upon the tube 1 mm. from the base, erect; filaments 
0.5 mm. long, glabrous; anthers linearly oblong, with rounded 
ends, 1.25 mm. long, subbasifixed; ovary rim glabrous, otherwise 
enclosed by the calyx; style slender, glabrous, as long as the corolla, 
terminated by 2 short thick pulverulent lobes; capsule nearly 
7.5 mm. wide, 3.5 mm. high, much flattened, ends rounded, 
dehiscing across the top and dividing into 2 valves, shining, 
smooth on the inner side, sparsely hirsute, the linear calyx 
segments still persistent; placentae 2, ascending, short clavate,
