must be spared root disturbance in later stages. (This, I think, has generally 

 failed.) 



Swertia Sp. (F 334) is but an annual, I fear, and may indeed be nothing 

 more than a specially fine Asiatic development of Pleurogyne carinthiaca. It 

 abounds in the open turf all over the upper Alps of the Min S'an and Thunder- 

 crown, from 9000 to 14,000 feet, and is really most beautiful in September, 

 forming loose 6- to 8-inch pyramids of large wide saucer-shaped flowers of a 

 lovely soft clear electric blue, growing in exactly the same turfy open slopes 

 that breed Pleurogyne above the Glocknerhaus. But this is so attractive as 

 well to deserve an annual sowing, in light grass or little interstices of turf. . 



Veronica pyrolaefolia is a most pleasant Chinese Speedwell, running 

 about comfortably over the ground after the fashion of V. officinalis, with shoots 

 clad in rather large soft rounded leaves, and sending up in summer croziers of 

 blossom exactly suggesting a Lily-of-the-Valley that has gone of a soft lavender 

 blue. It is a very valuable garden plant indeed.
