Gentiana lutea, Lmn. 



Sub-alpine tracts of Middle and Southern Europe. A beautiful 

 perennial herb, yielding the medicinal gentian-root. It could be 

 easily raised in high mountains elsewhere. Chemical principles: 

 gentian-bitter and geutianin. Medicinal gentian-root is also obtained 

 from G. punctata, L., G. purpurea, L. and G. panonica, Scop., of 

 the European Alps. Several native species are used as substitutes 

 in North-America, particularly G. quinqueflora (Lamarck).

 tain-regions to 3,000 feet.

The "Avens" of Britain. Europe, North-Africa, extra-tropical 

 and alpine Asia, South-Eastern Australia, North- America. A peren- 

 nial herb; the powerful anti-dysenteric root, according to Muspratt, 

 contains as much as 41 per cent, of tannic acid.

 at a height of about 120 feet.
