Iwp states is treated as referable to M. horridula, the latter 

 being considered a distinct species. 



So far as concerns that portion of var. racemosa, as defined in 

 1896, which, in the Pfianzenreicli, lias been left in M, horridula, 

 unother diii'erence of opinion has been expressed. It is 

 suggested in the Ffianzenreich that this state, which is there

In 1906, ^on the other hand, the opinion was expressed that 

 it -IS the racemose condition which is normal, and that 

 the condition which for technical reasons we are under the 

 necessity of describing as the ''typical" form is a reduced 

 condition. The evidence available since 1906 has. tended to con- 

 tirm this view. Seeds, accompanied by specimens, have on several 

 occasions since then reached this country from the neigh- 

 bourhood of Gyantse and elsewhere in southern Tibet. These 

 specimens liave always been referable to typical M. horridula 

 because they have always had only simple 1-fiowered scapes, 

 iiut no one has so far been able to raise a plant with simple 

 1-tlowered scapes ; the plants raised have alwavs formed central

Regarding the general question as to whether the state in which 

 ail the^scapes are simple and radical can be kept apart from either 

 oi the two states m which there is a central raceme-like compound 

 scape, it has co be noted that even in Tibet, where th- ^--^^ ^ilh 

 only simple scapes is the most common of the three,
