336 GENTIAXA. [CLASS v. order n. 



Stainens arising from about the middle oi' the tube, and about the 

 same length, filaments awl-shaped. Anlltcrs of t«o long narrow 

 cells, united round the style. >Slyles united, as long as the stamens. 

 Stiymas semi-orbicular toothed.

We have some doubt as to the claim this has tobe admitted as a native 

 plant, it having most probably escaped from the garden, where it is much 

 cultivated for the beauty of its rich flowers, either in small bedsor along 

 the borders, and certainly few flowers surpass it in the richness and 

 splendour of its colours It is frequent on the mountain pastures of 

 the Continent, and is sometimes used as a tonic, a principle possessed 

 by all the plants of this order. Several varieties are mentioned of this 

 plant, depending upon the length of the stem and the size and width 

 of the leaves, as growing upon the Appenine mountains, in Italy.

Root of numerous long stout simple brown branches. Stem simple, 

 solitary, or several from the same root, square, erect or bent at the

 Capsule of one cell, surrounded by the withered flower, oblong, 

 cylindrical, on a contracted footstalk, pointed at the extremity by the 

 styles, which roll back, and separate the two valves at the ajicx for the
