 fruit, setose with slender bristles ; corolla white, tube barely 3 mm. long, shorter than the sepals 

 in anthesis, limb 4 mm. broad ; nutlets narrowly lanceolate, 3 mm. long, narrowly wing-margined, 

 slightly glossy, dorsal side tuberculate, the tubercles sometimes forming short rugae, ventral 

 surface nearly smooth ; scar straight, extending from near the base nearly to the apex, narrow 

 but open, the margin not elevated.

 of the stem ; individual cymes elongated ; bracts foliaceous and conspicuous ; calyx-lobes lanceo- 

 late in anthesis, 4 mm. long, becoming 10-12 mm. long and linear in fruit, setose, the bristles 

 often somewhat fulvous; corolla white, tube 3-4 mm. long, about equaling the calyx, limb 6-8 

 mm. broad; nutlets usually only 1 or 2 maturing, lanceolate-ovate, obtuse, 4.5 mm. long, dorsal
