Leaf -segments and caljoi-lobes lanceolate or broader. Corolla 

 externally pubescent, its lobes ovate. Capsule ovate or 

 ovate-acuminate, glandular-tomentose. Seeds 1-1-5 mm. long, 

 with reticulations raised and wing-like. Stem with spreading 

 or reflexed hairs. 

 Filaments 1.5-2.5 mm. long, dilated and pubescent at least one 

 half their length, the distal portion glabrous. Anther -cells, 

 opening one half their length. Capsule ovate -acuminate 

 with gland-tipped hairs. Reticulations of seed regular, raised 

 less than the diameter of the seed. Stem glandular-pubes- 

 cent with spreading hairs. 

 Capsule 9-12 mm. long. Seeds 1-1.2 mm. long. Pedicels 

 7-12 mm. long. Leaf-blades slightly bipinnatifid. 



1. A. havardii.

3-5 (-9) mm. long. Leaf -blades strongly bipinnatifid. 



2. A. texana. 

 Filaments 3 mm. long, dilated and pubescent about one fourth 



their length, the distal portion lanose with spreading hairs. 

 Anther-cells opening one fourth or one fifth length. Capsule 

 5-7 mm. long, ovate, with mostly dark-jointed but not gland- 

 tipped hairs. Reticulations of seed irregularly produced into 

 three or four wings, which equal or exceed the diameter of the 

 seed. Stem pubescent with fine reflexed or also longer spread-
