 on short peduncles. The Calyx deeply divided into live sharp 

 segments, is persistent, and slightly hairy. The Corolla entire, 

 somewhat longer than the calyx, ringent, the lower lip white 

 and divided into three lobes, the upper of a reddish hue and 

 entire. The Stamens are four in number, of which two are 

 longer than the others ; the anthers two lobed. The Pistil 

 consists of a conical germ, a short and tapering style, and a 

 double stigma. The Capsule is conical, oblong, two valved.

 considered as a very good vulnerary, bruised and applied ex- 

 ternally, or taken internally as a decoction. Vahl affirms, on

 the V. pratensis is used in the cure of Syphilis.
