 from 1-2 feet high in subalpine places. Stem green or purplish. 

 Flowers white. The root is extremely bitter, and might be 

 useful in fevers, loss of appetite, &c. An infusion of it in wine 

 has been given with success in disorders of the stomach. It 

 yields an aromatic resinous oil on being wounded, and being 

 made into a syrup, is recommended in disorders of the breast.

 3-5-cleft, mucronate; leaves of involucra linear-lanceolate, acu- 

 minated ; wings of fruit equal, flat. 1. H. Native of the

 theat. 938. f. 1. L. trifurcatum, Lam. fl. fr. 3. p. 415. L. 

 cuneatum, Mcench. meth. 79. There is a variety with broader 

 segments (in Mor. hist. sect. 9. t. 19. f. 8.) and with the lobes 

 very much divaricate and short (Pluk. aim. t. 199. f. 1. L. 

 formosum, Willd. spec. 1. p. 1518.); segments of leaves ob- 

 long-linear (Mor. hist. sect. 9. t. 19. f. 9. and therefore L. an- 

 gustifolium, Lin. spec. p. 357.) ; segments of leaves very 

 narrow (J. Bauh. hist. 3. p. 137. and therefore L. angustifolium, 

 Willd. 1. c.) segments of leaves cut into many lobes (L. Galli- 

 jcum laciniatum, Hortul, &c.). The most of the varieties have 

 glabrous stems ; very few have them hispid from scattered bris- 



tles. L. tenuifolium, Riv. pent. irr. 22. is also a variety of this 

 species. Flowers white.

 lets (Jacq. icon. rar. 2. t. 250.) ; oblong-linear leaflets (Seg. 

 ver. 3. p. 227. t. 7.); and linear leaflets (Pluk. aim. t. 198. f. 

 4.) but all these varieties differ from any of those of L. Gdllicum 

 in the segments of the leaves not being cuneated nor lobed. 

 Flowers white.
