Corolla lavender-pink, no yellow lines nor darker 

 spots evident within throat. Capsule 3.5-5 mm. 

 long. Plant bright-green, little darkening in dry- 

 ing. Stem smooth or nearly so. Axillary fas- 

 cicles abundantly developed. 



8. A. georgiana. 

 Inflorescence usually of short or much broken racemes 



(if elongated and normal, pedicels over 10 mm. long), 

 usually some flowers by slower or arrested growth of 

 stem-apex appearing terminal. Pedicels 5-50 mm. 

 long. 

 Stem scabrous. Corolla pubescent within in narrow line 

 l^elow sinus of posterior lobes. Anther-sacs strongly 

 mucronate-caudate at distal apex, densely lanose 

 with pink hairs on the sides. Seed-coat with dark- 

 brown reticulations, areas between these more or less 

 hexagonal, pale and not reticulated. Stem-leaves 

 opposite, axillary fascicles abundantly developed. 

 Pedicels 25-40 mm. long. Corolla 25 3C ::im. long. 



9. A. pulchella. 

 Stem glabrous or essentially so. Corolla pubescent 



within over entire width of basal portions of pos- 

 terior lobes. Anther-sacs acute to minutely mucron- 

 ate-caudate at distal apex, glabrous over much of 

 dorsal surface. Seed-coat with dark-brown reticu- 

 lations, areas between these elongated, scarcely 

 paler, and scarcely or not reticulated. 

 Stem-leaves alternate, widening distally, slightly fleshy. 

 Axillary fascicles abundantly developed. Stigma 

 3.5-5.5 mm. long. Pedicels 20-35 mm. long. 

 Corolla 22-28 mm. long. 



10. A.filifolia. 

 Stem-leaves all opposite, not widening distally, not 



fleshy. Axillary fascicles not or scarcely devel- 

 oped. Stigma 1-2 mm. long. 

 Branches very widely and laxly ascending. Pedicels 

 25-50 mm. long, very slender, four or five times 

 as long as the bracts. Corolla 15-18 mm. long, 

 paler rose-pink. Seeds .3-.5 mm. long. 



11. A. loxa. 

 Branches more closely and stiffly ascending. Pedi- 

 cels 4-40 mm. long, less than twice as long as 

 the bracts. Corolla 15-30 mm. long, deeper 

 rose-pink. Seeds .5-.9 mm. long. 



Leaves 2-3.5 cm. long, equaling or exceeding the 



internodes, slightly scabrous to glabrous 



above. 



Pedicels 15-40 mm. long, longer than the bracts. 



Calyx-tube |-1 the length of the capsule.
