The foliage of this species recalls the charming Rh. Souliet, 
Franch. and it is a member of the Souliei series. Unfortunately 
Mr. Forrest’s specimens are not abundant, and we have as yet 
inadequate material for a complete comparative analysis of the 
two species, but we have enough to bring out definite differences 
between them. Rh. Souliei is now a familiar plant of cultiva- 
tion, thriving at Edinburgh in any situation, and Rh.callimorphum 
introduced by Mr. J. C. Williams, has flowered (May 1917) aud 
appears to be as desirable a species as Rh. Souliei. By the 
character of foliage the two plants are easily diagnosed. RA. 
callimorphum has abundance of red glands appearing as minute 
dark points distributed over the under surface of the leaf and 
the petiole is clad with sessile globular glands. Rh. Souliei has 
no glands on the leaf under side and the petiole bears more or 
fewer stalked red glands which often extend to the margin of
