Perennial. July. 



Stem bushy, branching from the bottom, bluntly quadrangular, 

 leafy, clothed with fine woolly pubescence. Leaves on longish 

 stalks, except the upper ones, which are nearly sessile ; their 

 shape and size, as well as the degree of their woolliness, various j 

 their surfaces wrinkled and veiny. Fl. white, in dense convex 

 whorls. Calyx-teeth rigid, recurved at the point, all spreading j

 for coughs and asthmatic complaints. 



Clusius, Gerarde and Lobel give, for this plant, a figure with a 

 vaulted corolla, which has been too incautiously copied and 

 quoted.
