Argemone pinnatifida n. sp. 



Low, 3 dm. high, scarcely branched ; leaves of the inflo- 

 rescence small, thus giving a somewhat pedunculate appear- 

 ance; spines few on stems and leaves, more abundant on the 

 calyx; leaves deeply pinnatifid, the lobes deeply incised- 

 dentate, the lobes and teeth spreading and not ascending as 

 in related species; flowers rather small. 



I have seen two specimens of this species, both from Texas. 

 They are: Heller, Corpus Christi, no. 1378, 1894; Jermy, 

 Gillespie Co., no. 218. 



LiNUM Lewisii pratense n. var.

 crowded, narrowly linear, somewhat fleshy, 5 to 15 mm. long, 

 1mm. wide; flowers small, whitish; capsule large, very 

 obtuse. — Saline plains, Kansas to Texas. — Plate VI.

The typical L. Leioisii Pursh, with tall, slightly branched 

 stems, large blue flowers, larger, more lanceolate leaves and 

 more pointed capsules, is found in the more mountainous 

 parts of the Western States.

The Texan plants referred to the above name were easily 

 recognized by Mr. Bush as distinct from any recognized 

 species of the United States, and they seem to be very easily
