 tapering, simple. Flowers white. There are several barren or

 The root is said to serve the Russians for ginger ; and the whole 

 herb abounds with a white, bitter, fetid juice, of the consistence 

 of cream, which soon dries to a brown acrid resin. The milky 

 exudation is the only character by which Tournefort distinguishes 

 his Thyoselmum from his Oreoselinum.
