able to P. deflera, Duthie, but hardly distinguishable from 
the plant figured by Pax and Knuth as P. Viali, the other 
not distinguishable from the Eastern Himalayan P. bellidi- 
folia, King. But Ford’s two plants, though distinguishable, 
are so nearly related that his opinion, based on field obser- 
vation, as to their specific identity may be correct; by 
parity of reasoning there is nothing improbable in the views 
of Pax and Knuth and of Franchet respectively, or in a 
suggestion that all these forms may be referable to one 
variable species first named P. bellidifolia by the late 
Sir George King. This being so, it is not surprising that. 
so experienced a field observer as Mr, E. H. Wilson should 
consider the plant here figured to be only a strong form of 
P. Viali, Delavay. On the other hand, photographs of 
P. Littoniana, taken in the field, indicate a degree of 
uniformity among the particular plants involved that does 
not admit of bemg lightly put aside, so that, in spite of 
the fact that the differential characters pointed out by 
Mr. Craib are far from convincing, it is convenient, from 
the gardening standpoint, to treat P. Littoniana and P. Vialt, 
for the moment, as distinct.
