of it as that species by M. Petitmengin. Franchet : tells us 

 that the plant he described as P. bullata, Franchet, is 

 No. 114 of Delavay's collection. Amongst the plants sent 

 to Edinburgh from Paris there is a specimen with this 

 number, and I take it to be the true P. bullata of Franchet, 

 matching as it does the description save in the clothing of 

 the scape. Franchet says the scape is scabrid. I can only 

 find a faint puberulousness at its base on the single specimen 

 in our herbarium. This true P. bullata, Franchet, is an 

 entirely different plant from that which I have described 

 as P. rufa, Balf. fil., and indeed the surface distinctions are 

 plain. I tabulate the prominent ones : — 

 P. bullata, Franch. P. rufa, Balf. fil. 



Plant glabrous all over. Plant glanduloso-pilose. 



Scape very glabrous, farm- Scape hairy, not farinose, 

 ose at top. 



Bracts farinose without Bracts efarinose, hairy, 

 hairs. 



Pedicels farinose without Pedicels efarinose and hairy. 

 hairs. 



Calyx farinose without hairs. Calyx hairy and farinose. 



P. rufa, Balf. fil., has a much nearer ally in P. Forrestii, 

 Balf. fil., from which it may not be found possible to 

 separate it by distinctive marks, but without additional 

 material showing connecting stages I prefer to keep it as a 

 separate species.
