baskets. The Linnaea boreaUs or twin-flower is native in the cool damp woods 

 of the North. 



Several of the viburnums are cultivated. The hobblelnish (V. alnifoUum), 

 a native from Ontario and southward, is frequently cultivated in the East. 

 The cranberry-tree or guelder rose (f. Opulus) found along streams from 

 New Brunswick to northeastern Iowa, is cultivated both in its native and cul- 

 tivated forms. The well-known snowball is a cultivated form of t)he cran- 

 berry tree. The fruit of this plant is used in the North. The root of horse 

 gentian {Triosteum perfoliaium) has a bitter taste and is used as a cathartic. 

 The flowers of the elder berry (Sambucus canadensis) are sudorific. The bark« 

 of Viburnum pninifoliuni, the black haw, is officinal, an antispasmodic, nervine 

 and an astringent. It is also used as an uterine sedative, contains viburnin, 

 oxalic acid, tannic acid, etc. The bark of V. Opulus is said to be antispasmodic. 

 Xylostein occurs in Lonicera Xylosteum. According to Greshoflf the leaf of 

 Viburnum macrophyllum and of Symphoricarpos mollis contain saponin.
