Seeds yellowish-brown. Plants not tending to blacken in dry- 

 ing. Calyx-tube evidently reticulate-venose. (Erectce.) 

 Stem evidently striate-four-angled, simple to modei^ately 

 branched. Leaves linear to nearly filiform, 1-2,5 cm. 

 long. Racemes well-developed, so flowers not conspicu- 

 ously "terminal." Stigma 1-2 mm. long. 

 Leaves linear to nearly filiform, not widening distally, 

 acutish to acuminate. Corolla with two yellow lines 

 and purple -red spots within throat strongly defined. 

 Capsule globose to globose-ovoid, somewhat flattened 

 at base. 

 Leaves 2-2.5 cm. long, filiform-linear, relatively scabrous 

 above. Pedicels one to three times the length of the 

 bracts. Corolla 13-15 mm. long. Seeds .6-.8 mm. 

 long. 18. A. decemloba. 



Leaves 1-1.5 (-2) cm. long, linear-filiform to nearly fili- 

 form, slightly scabrous above. Pedicels mostly three 

 to eight times the length of the bracts. Corolla 15- 

 20 mm. long. Seeds .9-1.1 mm. long. 



19. A. tenella. 

 Leaves linear, widening distally, acutish to obtuse, 1-1.5 

 (-1.8) cm. long. Corolla with lines and spots within 

 throat faint or obsolete. Capsule globose-ovoid to 

 globose-elliptic, rounded at base. Corolla 12-16 mm. 

 long. 20. A. ereda. 



Stem nearly terete, much branched. Leaves narrowly linear, 

 2-3 cm. long. Racemes scarcely developed, so flow^ers 

 scattered and conspicuously "terminal." Stigma 2-3 

 mm. long. Corolla 12-18 mm. long. 



21. A. gattingeri. 

 Corolla with posterior lobes arched over stamens and style, glab- 

 rous within at their base. (Tenuifob'ce.) 

 Corolla pubescent externally, its posterior lobes about two- 

 thirds the length of the anterior, minutely ciliate, concave- 

 arched. Pedicels, if exceeding the bracts, less than twice 

 their length. Corolla 10-23 mm. long, rose-pink. Leaves 

 linear. 

 Corolla 15-23 mm. long. 22a. A. tenuifolia leucanthera. 



Corolla 10-15 mm. long. 



Leaves linear, 1-6 mm. w^ide, those of the stem obviously 

 wider than those of the branches. 

 Calyx-lobes mostly 1-2 mm. long. Capsule mostly 5-7 

 mm. long. Seeds .7-1.3 mm. long, with reticulations 

 more pronounced. Leaves 1-6 mm. wide. 



22b. A . tenuifolia macrophylla. 

 Calyx-lobes mostly less than 1 mm. long. Capsule 

 mostly 3-4 mm. long. Seeds .6-.9 mm. long, with 

 reticulations very fine. Leaves 1-3.5 mm. wide. 



22. A. tenuifolia.
