Franchet, we have one of the short-scaped forms from 

 which farina is absent. It is a yellow-flowered plant also. 

 P. Lacei, Hemsley et Watt, is also yellow-flowered — an 

 outlier in the way of its distribution and unique in the 

 possession of the white or golden hairs which give it a 

 woolly character — and showing the retarded scape develop- 

 ment already mentioned. P. Monbeigii, Balf. til., and 

 P. Dubernardiana, G. Forrest, are two plants with larger 

 flowers than those in other members of the group, and their 

 flowers are rose-pink ; the species are readily distinguished 

 by foliage character. P. pseudobracteata, Petitmengin, and 

 P. Henrici, Bureau et Franchet, I am unable to show. I 

 know them only by description : the former intermediate 

 between P. bract eata, Franchet, and P. Lacei, Hemsley et 

 Watt; the latter distinct in the group by its solitary 

 flower.
