21. L. onustus "Wats. Ground Lupine. Plants dwarfish, 4 to 9 inches high; 

 stems few from the root-crown, simple or subsimple, slender, scarcely longer than 

 the petioles, somewhat flexuose and, with the long-petioled leaves, often simulating 

 a corymbose habit; herbage pubescent, the stems and petioles also with long inter-

 so, few-flowered, the flowers scattered, 4 lines long ; petals blue ; banner glabrous ; 

 keel ciliate ; pods hairy, 1^4 to 1^^ inches long, 5 lines wide ; o\'ules 5 or 6.

 Creek, Trinity Co., H. S. Yates 339. 



Habit note. — Lupinus onustus, in spite of its fairly wide range, is probably rather rarein 

 individuals, and in any event is seldom collected. It is well-marked by its low habit and peculiar 

 branching. The long-petioled primary leaves usually bear in their axils extremely short or dwarf 

 branchlets which produce only a pair of long-petioled secondary leaves. The leaves tend, there- 

 fore, to appear a little fascicled.
