native of France* Switzerland, Italy, &c. flowering all the summer 

 and autumn. 



The second species has the root not so large as in the first sort: 

 the stems two feet high or more, branching on each side from the 

 root to within six inches of the top: the leaves three or four inches 

 long, but as narrow as those of flax: the upper part of the stem 

 naked, and terminated by a compact corymb of bright red flowers, 

 smaller than those of the former. It is a native of the mountains of 

 France, Switzerland, &c. 



The third is an annual plant: the lower leaves, which spread on 

 the ground, are cut into many obtuse segments: the stalks, when the 

 plants are in good ground, rise near a foot and half high, but upon 

 dry stony soils not half so high, and when they grow out of the joints 

 of old walls, not more than three inches in height; are hollow, 

 smooth, and round, sending out branches by pairs from the upper 

 joints: the segments of the pinnatifid leaves are very narrow: stem 

 and branches terminated by tufts (corymbs) of flowers shaped like 

 those of the fourth sort, but smaller and tinged with flesh-colour at 

 the top. It is a native of the South of France, &c. flqwering early 

 in the spring. . . 



It varies with the lower leaves pinnaliful. 



The fourth species has thick roots, fleshy, jointed, spreading near 

 the surface in a very irregular manner, crossing ruch other, and 

 matting together by their small fibres: many of the root-leaves 

 entire, others divided into three, five, or seven, obtuse lobes of a 

 pale green, and quite smooth: the stems throe or four feet high, 

 hollow, sending out lateral branches by pairs: the stem-leaves oppo- 

 site at each joint, composed of four or five pairs of long narrow 

 leaflets, terminated by an odd one: the stem and branches termi- 

 nated by corymbs of small white flowers. It is a native of Silesia, 

 Barbary, Sec. flowering from May to July, with the odour of the 

 flowers very pleasant. 



The fifth has a perennial root, long, unequal, brownish, strong- 

 smelling: the root-leaves oblong-cordate, bluntish, smooth, obtusely 

 serrate- toothed, on long petioles; the two first of these that come out
