channelled above. Fl. purple, often white, sweet-scented. Fr.- 

 sep. triangular, acute, twice as long as broad, not ciliate, gla- 

 brous. Bracts above the middle of the flower stalk. Petioles with 

 deflexed hairs. Several species (?) allied to this are nearly or 

 quite scentless : V.permirta (Jord.) has a large glabrous glan- 

 dulir-dentioulate stip. ciliate towards the tip, short robust 

 stoles usually not rooting, fl. pale blue: V. sepincola (Jord.) 

 has large glandular-denticulate stip., longer somewhat rooting 

 stoles, and much darker flowers. These plants and their allies 

 seem quite different when growing, but are very difficult to 

 define. Some authors join them to V. hirta. Common. P. III.

 cells diverging below. Spur of the petals compressed, not 

 channelled. Fl. pale blue sometimes white, scentless. Fr.- 

 sep. roundly triangular, bluntish, as long as broad, more or less
