Calyx 5-toothed. Corolla with the 4 upper lobes nearly equal, oblong, turned 

 forward, so that there seems to be no upper lip ; the lower one much larger.

 Herbaceous, downy; stem erect (l-3 high) ; leaves ovate-lanceolate, serrate, 

 rounded at the base, short-petioled, hoary underneath ; the floral scarcely longer 

 than the oblique unequally-toothed calyx ; whorls about 6-flowered, crowded in

Calyx bell-shaped, oblique, deeply 5-cleft ; the 3 upper teeth elongated and 

 partly united, the 2 lower very short. Corolla 5-lobed ; the lobes narrowly ob- 

 long, declined, nearly equal in length ; the 3 lower more or less united. Sta- 

 mens 4, with very long capillary filaments, exserted much beyond the corolla, 

 curved : anther-cells divergent and at length confluent. Low annuals, some- 

 what clammy-glandular and balsamic, branched, with entire leaves, and mostly 

 solitary 1 -flowered pedicels terminating the branches, becoming lateral by the 

 production of axillary branchlets, and the flower appearing to be reversed, 

 namely, the short teeth of the calyx upward, &c. Corolla blue, varying to pur- 

 ple, rarely white, small. (Name composed of 6pi, hair, and arfjp.a, stamen, 

 from the capillary filaments.)
