 pubescent to -villose. Pedicels 4-20 mm. long. Calyx-tube 

 hemispheric, glandular-hirsute to -lanose. Capsule broadly 

 ovoid, 11-16 mm. long, only its base enclosed in the calyx- 

 tube. Seeds 1 mm. long. 

 Stem stiffly branched. Leaves all spreading, the upper smaller 

 but not excessively reduced, those of the stem 2-6 cm. 

 long. Pedicels 4-20 mm. long, conspicuous when in flower. 

 Calyx-tube glandular-hirsute to -lanose. Corolla 30-40 

 mm. long. Anther-sacs ovate. 



2. A. pectinata. 

 Stem virgately branched. Leaves, at least the upper, appressed- 

 ascending, uppermost leaves very much reduced, those of 

 the stem 1.5-3 (-4) cm. long. Pedicels 4-9 mm. long, 

 usually very short when in flower. Calyx-tube glandular- 

 lanose. Corolla 38-45 mm. long. Anther-sacs lanceolate- 

 ovate 2a. A. pectinata floridana. 

 Perennials. Not glandular. Leaves entire to somewhat coarsely 

 bipinnatifid, not pectinately cut. Calyx-lobes entire to dentate. 

 Corolla externally glabrous, within glabrous or difTused-pubes- 

 cent; not marked nor tinged with purple-red. Anther-sacs 

 4-6 mm. long. Capsule ovate to globose ovate in outline, 

 not glandular. Seeds 1.3-2.7 mm. long, strongly winged. 



(Aweolaria, sensu strictu.) 

 Capsule densely rusty-pubescent. Pedicels 1.5-3 mm. long. 

 Stem puberulent to pubescent, at least above. 

 Stem puberulent to pubescent throughout. Leaves perma- 

 nently downy-pubescent. Capsule 12-15 mm. long. Seeds 

 1.5-1.8 mm. long 3. A. virginica.

 puberulent becoming glabrous. Capsule 9-12 mm. long. 

 Seeds 1.3-1.5 mm. long. 4. A. ynicrocarpa. 



Capsule glabrous. Pedicels 3-25 mm. long. Stem glabrous to 

 minutely puberulent. 

 Bracts entire to finely crenate-serrate. Pedicels slender, 15- 



25 mm. long. 5. A. patula. 



Bracts entire to coarsely dentate. Pedicels stouter, 3-15 mm. 

 long. 

 Lower leaves ovate-lanceolate in general outline, widest about 

 the middle, not long-acuminate. Petioles evident, mostly 

 10-30 mm. long. Pedicels 5-15 mm. long. Calyx densely 

 pubescent within. Corolla 35-60 mm. long. Capsule 

 12-24 mm. long. Seeds 2-2.7 mm. long. Stem rela- 

 tively stout, frequently purple.
