GENTIANA (after Gentius, king (if lUyricum, who is 

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

 (icntiandcea'. Gentians are amongst the most desirable 

 of alpine plants, and of blue flowers in general, but 

 they are generally considered difficult to establish. The 

 genus is the largest in the order, and from a garden 

 point of view the most important. About ISO species, 

 widely scattered in t€*mperate and mountainous regions. 

 ('hiefly perennial herbs, rarely annual or biennial, often 

 dwarf, dilTuse or tufted, sometimes erect and slender, 

 or even tall and stout: Ivs. opposite, mostly sessile: 

 fls. blue, violet, purple, rarely dull yellow or white; floral 

 jiarts typically 5, rarely 4-7. 



The Blue Gentian, celebrated by tourists in the Alps, 

 is probably mostly the stemless tientian, 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 

 .•^ome split into .5 distinct species, of which G. angnsti- 

 fi'lia of Villars (not I\[icliaux} is nearest to the Gentian- 

 clla of English gardens. It has been so much modiflcd 

 in cultivation that it now lias stems 4-f> inches higli. and
