GENTIANA (after Gentius, king of lllyricum, who is 

 said to have discovered the tonic value of tliese plants). 

 Gentiandcem. Gentians are amongst th.- in..si .l.-^jraljle 

 of alpine plants, and of blue flow.f^ in t:.iH ral. but 

 they are generally considered diflicult i.. .-^tal.li-li. The 

 genus is the largest in the order, and fri.iii ;i ^'arden 

 point of view the most important. About 180 sj.ecies, 

 widely scattered in temperate and mountainous regions. 

 Chiefly perennial herbs, rarely annual or biennial, often 

 d\v:irf. diftuse or tufted, sometimes erect and slender, 



r . .1! lull 1 stout: Ivs. opposite, mostly sessile: 



I, |. II r]de, rarely dull yellow or white; floral 



, : ■ , , . :.. rarely 4-7. 



il.. |;iiii I ..III iau, celebrated by tourists in the Alps, 

 IS |,r,,l,aljly uiustly the stemless Gentian, G. acaulis. 

 This was brought to English gardens so long ago that 

 all record of its introduction is lost. It is by far the 

 most popular kind in cultivation. This species is by 

 some split into 5 distinct species, of which G. angusti- 

 folia of Villars (not Michaux) is nearest to the Gentian- 

 ella of English gardens. It has been so much iiiodifled 

 in cultivation that it now has stems 4-6 inches high, and
