does not always close on the approach of twilight. There 

 are better and poorer flowered individuals noticeable in the 

 cultivated plants — some opening the trumpet widely, others 

 keeping the corolla-lobes more erect. It begins to flower 

 at Edinburgh in late August, and continues until winter 

 frosts destroy its aerial shoots. Rooting as it does at every 

 node propagation of it is easy. 



When in flower there is no other species with which 

 G. Farreri can be confused. The Siberian G. Lawrencei, 

 Burkill, is its nearest ally, but that wants the fine flower- 

 colour, its flowers do not open in the wide trumpet-form 

 of G. Frirreri, and its leaves and stem are altogether more 

 delicate. From G. sino-ornata, Balf. f., and G. Veitchi- 

 orivm, Hemsl., others of its allies, it is easily diagnosed. 

 They have flowers of a royal blue and purple-blue colour, 

 and the latter has shorter blunt leaves.

A handsome Gentian, brought into cultivation by Herr Max Leichtlin 

 of Baden-Baden. The specimens from which the description is drawn 

 flowered in the garden of Sir 'J'ie\'or Lawrence at liurford, Dorking, to 

 whom we are indebted for the specimens liere illustrated. The original 

 seeds were collected by M. Jules Bocherel on a journey into Mongolia 

 from Lake J-5aikal. Gentiana ornata, its nearest ally, is a native of the 

 Eastern Himalaya and South-W^est China. Gentiana ternifolia, Franchet, 

 is another ally wliich couies from Yunnan ; Gentiana tetraj)hylla, 

 Kusnezow, and G. Jiexaphylla Maximowicz, are allies growing in
