Habitat. ^Woods, not unfrequent in England; old walls. Mug- 

 doch Castle, near Glasgow, Scotland. — 3Tr. Hopkirk. Between 

 Glasnevin and Finglass. — Dr. Brinliloi. River side below Innis- 

 trogue, County of Kilkenny, Ireland. — Mr. Templcton. 



Perennial; flowering in July and August. 



The English name of this plant is from the resemblance of the leaves 

 to those of a nettle; its hairs are also almost as pungent, but they are 

 not venomous. Formerly a decoction of its leaves was thought useful 

 in inflammatory aff'ections of the throat and mouth ; hence its specific 

 name of Tracheliiim. It is, however, we believe, not now used for that 

 purpose; it contains ai^ acrid milky juice, and may have been useful 

 as a stimulating gargle. It is cultivated as a border flower, and is 

 very ornamental, the flowers often becoming very double, and some- 

 times quite white. 



** Flowers sessile, spiked^ or collected into a terminal head. Capsule 

 openiny by lateral pores.
