side. We have seen specimens heavily spotted with claret 

 nearly up to the petal tips, and others scarcely at all 

 spotted and with a faint lilac flush at the throat. A few- 

 only are fragrant. Inhabits varied sites on high mountain 

 ranges 4000 ft. to 6000 ft. above sea-level. Upper Burma

 stems indicate association with scrub." 



Doubts arose as to the specific distinctness of Loxvii 

 from Bakerianum. The general trend was to regard it 

 as a variety at most. Yunnan plants were mentioned as 

 the same but without reference to any distinct species 

 of Franchet. The latter's diagnoses of Delavayi and of 

 yunnanense appeared in September 1892 (Journ. de Bot., 

 vi, p. 314). Yunnanense appears first and is compared 

 with, japonicum, Thunb., as regards the flower. Delavayi 

 on the same page has its flowers contrasted with candidum. 

 Even in the key, op. cit. 308, the two species are not so 

 placed as to suggest comparison except as regards colour 

 distinctions. Yunnanense is placed among the species 

 with flowers white or tinted violet on the exterior. 

 Delavayi among '• rouge coccine ou lie du vin presque 

 toujours maculees de brun ou de noir." It must be said 

 for Franchet that in the type specimens there is no 

 immediate suggestion of proximity, but the access of 

 ampler material of these lilies has brought forms which 

 bridge the gap between the two. Yunnanense occupies 

 the place of Bakerianum, while Delavayi has a very close 

 connection with Loivii. We have consequently in Burma 

 the white Bakerianum giving at the extreme the deep 

 spotted or tesselated Loivii and in Yunnan the white 

 yunnanense extending to the olive dark-spotted Delavayi. 



Forrest has collected yunnanense in Yunnan several 

 times : — 



Mountains in the north-east of the Yangtze bend, flowers 

 pure white, minutely speckled maroon on basal half interior, 

 fragrant. No. 10,545 ; Kari Pass, Mekong- Yangtze Divide, 

 flowers white, faintly tinged rose on exterior. No. 12,977. 

 (This is a remarkable gatherino- in its variations ; the 

 largest plants are 2 ft. high with white flowers 3 ins. lono-; 

 there are also plants of 1 ft. high with rose-tinted, speckled
