360 9. GENTIANA PNEUMONAISTTHE. [CL. V, 



iamily, the Campanuleae, which stands between the Ericeae 

 and Lobehse ; (Anleit. 2. s. 522.) 



Uses, 



The root affords a milky substance, and is edible ; hence 

 the name Rapunculus, instead of which they use the term 

 Wild Rape, in Germany. In some countries the plant is 

 reared in gardens, and the root and young leaves are used in 

 spring as greens.

This plant grows on peat-mosses and moist meadows in 

 August, and is distinguished, at first glance, by its beautiful 

 Berlin blue flowers, which are of considerable size. 



From a small yellowish-brown fibrous root, there rises a 

 stem of the thickness of a straw, of a large span long, simple, 

 somewhat angular, sharp to the touch, but otherwise smooth. 

 The leaves, which are almost linear, somewhat obtuse, quite 

 entire, of an inch long, of a shining green on their upper 

 surface, sharp to the touch on their lower, embrace the stem 

 with their tapering base, stand opposite to one another, but 

 so that the nearest pairs form a right angle with one another, 

 and are thus cruciform, (36.) 



On the uppermost axillae spring the flowers upon short 

 stalks. The flowers consist of a tubular five-toothed, or 

 five-lobed calyx, the teeth of which, at an after period, are 

 reflex, — and of a monopetalous corolla, bell- shaped, of a 

 Berlin blue colour, internally adorned with yellow points. 

 The margin of the corolla has five larger, and as many small- 

 er teeth. The aestivation is twisted, (99.) Five filaments 

 are united at their lower parts, with the base of the corolla. 

 The yellow, almost arrow-shaped anthers, also stand at first 

 in a cluster around the simple pistillum ; afterwards they se-
