 Kansu. Jo-Ni alps. Farrer and Purdom, 1914.^ 

 Specimens of this species were not brought by Farrer, 

 and my description is based upon living plants which 

 flowered in the Royal Botanic Garden in August 1916. 

 They were raised from seeds presented by the late Robert 

 Woodward, Esq., jun., of Arley Castle, Bewdley — a portion 

 of his share in the produce of Mr. Farrer's expedition. 



G. Farreri is a superb species, perhaps the finest of the 

 series to which it belongs. The wonderful sheen of the 

 blue of its petals and folds above the white throat is 

 its outstanding flower-feature, and the recurving of the 

 corolla shows ofl" the colour to advantage. It seems to be 

 less affected by weather conditions than is the case with 

 other Gentians. Sunshine is not necessary for the flower- 

 expansion, although in sunshine only is the full glorj^ of 

 its colour displayed. On dull cloudy days as in bright 

 sunshine the plant opens flowers freely. And the flower
