South East Tibet. Forrest. No. 308. Dry situations 

 on the ledges and in the clefts of cliffs on the eastern flank 

 of the Mekong-Salween divide, Mekong valley. Lat. 28° 6' N. 

 Alt. 8000-9000 feet. June- July 1904. 



This with P. Monheigii, Balf. fil., is a pink-flowered 

 species amongst allies having yellow flowers. Its nearest 

 relation is P. Monheigii, Balf. fil., but it wants the bullate 

 leaves and golden farina of that species, in which also the 

 calyx lobes are much shorter. From P. hracteata, Franchet, 

 in addition to the flower colour, the shape of the leaf and 

 the leafy involucre in that species are marks of separation. 

 P. Henrici, Bureau et Franchet, with which it has only 

 superficial resemblance, is separated easily by its solitary 

 flower and short calyx. 



From the description of Mr. Forrest we gather that this 

 plant in its native habitat on the limestone cliffs on the 

 banks of the Mekong, forms dense cushions one or two 

 feet in diameter — a striking sight when covered with its 

 rose blossoms, which are relatively large for this section. 

 In the size of flower it seems to resemble P. Monheigii, 

 Balf. fil.
