 on slender petioles one half as long as the blade : racemes elongated, 

 slender and flexuous, pedunculate, loosely-flowered, becoming 2 to 4 din. 

 long; pedicels filiform, spreading, at first 1 cm. long, in fruit becoming 

 5 cm. long ; bracts subulate, the lowest 1 cm. long, the upper much 

 shorter : calyx hemispherical, glabrous, in fruit 2.5 mm, long, hardly 

 equalling the lance-subulate teeth, and with a linear spur 5 mm. long, 

 bearing 2 subulate awns at the tip : corolla blue, 1.5 cm. long, the poste-

 axillary peduncles, becoming 6 or 7 cm. long; pedicels filiform, ascend- 

 ing, 1 cm. or so long, twice exceeding the subulate minutely toothed 

 bracts: calyx campanulate, the tube in fruit 3 or 3.5 mm. long, about 

 equalling the lanceolate teeth : corolla pale bluish, 8 mm. long, merely

 long, the upper shorter, strongly rugose, scabrous above, tomentulose 

 beneath : heads sessile or subsessile in the upper axils or in terminal
