oblanceolate, oblong or elliptic, thinnish, obtuse or notched at the 

 apex, undulate, truncate or subcordate at the base, sessile : cymes 

 terminal or axillary, few-flowered, sessile or short-peduncled ; 

 pedicels stout, 1-2 mm. long : sepals lanceolate or linear-lanceo- 

 late, 3-4 mm. long, acuminate : capsules oblong, about I cm. 

 long, acute, glabrous, striate. 



In low ground, Alabama and Florida. Summer. 

 A stronp-lv marked soecies related to Triadenum 



petioL 



with longer, thinner sessile or nearly sessile leaves, which are 

 truncate or partially clasping at the base. The sepals are lanceo- 

 late and acuminate, as contrasted with the oblong, obtuse sepals of 

 T. pctiolata. 



The originial label accompanying the type specimens reads as 

 follows : " In fossis prope Summerville, Alabama, et ad flu v.

Annual, strigose. Sterns branched at the base ; branches erect 

 or ascending, 1-3 dm. tall, commonly branching : leaves 1-4 cm. 

 long ; blades pinnatifid, the lower ones petioled, the upper sessile 

 and somewhat clasping ; segments acute : racemes many-flowered, 

 4-10 cm. long : pedicels about as long as the calyx at maturity : 

 calyx bristly ; segments linear, 5 mm. long, revolute : corolla pale 

 blue, 4 mm. broad ; segments oblique, irregularly toothed, pubes-

The habit of the

The calyx -seg-

 segments are irregularly toothed instead of laciniate. The glab- 

 rous filaments also serve as a means of separation.
