7. Dasystoma dispérsa Small. Perennial, inconspicuously puberulent, blackish in 
drying. Stems 4-10 dm. tall, simple or widely, but rather sparingly branched: leaf- 
blades spatulate, oblong, elliptic or oblong-oblanceolate, entire, 2-6 cm. long, or longer, 
and sometimes repand near the base of the stem, slender-petioled : racemes conspicuously 
interrupted, the pairs of flowers quite regularly separated by internodes 2-4 cm. long: 
calyx-tube 7-8 mm. broad during anthesis, puberulent or glabrate ; lobes about as long as 
the tube or usually shorter : corolla 3-3.5 em. long : capsules fully 1 cm. long.

8. Dasystoma pátula Chapm.  Perennial, finely pubescent or puberulent, at least 
on the stem. Stems 5-12 dm. tall, widely and loosely branching : leaf-blades various, those 
of the lower leaves 1~2-pinnatifid, ovate or ovate-lanceolate, 10-15 cm. long, those of the 
upper leaves oblong to oblong-lanceolate, entire or some of those about the middle of the 
stem serrate : pedicel slender or filiform, longer than the calyx and sometimes gu epe the 
spreading or reflexed bracts : calyx-lobes linear or nearly so, longer than the tube: corolla 
3-3.5 cm. long: capsules ovoid, 1-1.5 cm. long. 
On river banks, Tennessee and Georgia. Summer and fall. 
9. Dasystoma bignoniiflóra Small. Perennial, glabrous. Stems 1-2 m. tall, some- 
what glaucous, with ascending branches: leaf-blades 4-15 cm. long, the lower ones 1-2- 
pinnatifid, slender-petioled, the upper entire, mostly broadest above the middle : al 
tube 4-5 mm. broad during anthesis, the lobes often shorter than the tube : corolla 3.5-4.
