 mm. long, glandular, the crest about middle : corolla blue, 15-18 mm. long ; tube grad- 

 ually dilated from near the base, the upper lip with a retuse middle lobe and ovate lateral 

 lobes, the lower lip undulate, sometimes notched : nutlets 1 mm. in diameter, strongly 

 tuberculate. [S. canescens Nutt. ]
