Franchet's- types (rubro-vinosi) and Forrest's specimens 

 (olive, olive-brown, dull olive-green) are consistent in their 

 avoidance of white, while yunnanense is always in Forrest's 

 experience pure white (tinged sometimes with rose). Mr. 

 Forrest was at one time of the opinion that Delavayi 

 showed no refraction of the segment tips, but in photo- 

 graphs afterwards obtained by him in situ there is a 

 recurving similar to what is found in Bakerianwm. His 

 experience in the field of what have been termed yunnan- 

 ense and Delavayi led him to the conclusion that the two 

 are distinct from one another. Accordingly my inclination 

 is to keep Delavayi as a species closely allied though it 

 may be to L. Bakerianum ; to regard yunnanense as 

 equivalent to L. Bakerianum; to consider LoivH as a 

 spotted variety of Bakerianum on the way towards 

 Delavayi. I am, however, not at all sure but that Loivii 

 represents most forms of Delavayi, and as Lowii was 

 described first that name would have precedence. But the 

 name Delavayi represents the olive lily of Yunnan with 

 dark spots, and while the doubt remains, that name is on 

 the whole more worthy of retention. There is still L. 

 sempervivoideum, Levi. The original description in Bull, 

 de Geog. Bot., xxv. (1915), 38, is appended. 



"Insignissimum bulbo plurisquamatum ; squamis omnino 

 liberis lanceolatis confertissime rosulatis, erecto-patentibus, 

 folia graminea conferta 1-2 mm. lata curta; fios unicus 

 raro geminus albus, nutans, intus rufo vel rubro punctatus.

There is ample material of this in Herb. Levi. Henry, 

 No. 10,743, from Mengtze, with pink flowers may be con- 

 sidered along with it ; it was named yunnanense in Journ. 

 Linn. Soc, xxxvi. (1903), 136. It diflfers from Franchet's 

 description and tj^pes in (1) the stem being smooth and 

 not scabrid, (2) leaves scarcely tri-nerved and not scabrid 

 on the veins, (3) flowers pink and only 4-5 cm. long, (4) 

 the style is twice the ovary. To this in Herb. Kew., Mr. 

 Wilson has affixed the name of L. amoenum, Wils., but 

 after seeing Leveille's type of sempervivoide^im decided it 

 was equivalent. There is also in Herb. Edin. two gather-
