it receives. Adding P. Olgae, Rupr., a species not far removed from 

 P. auriculata, Lam., endemic in the Caucasus, and P. baldschuanica* 

 Fedtsch., a Turkestan plant, I have named all the certain species of 

 the section. 



Asiatic Species (neither Himalayan nor Chinese) of the 

 Auriculata Section. 

 Blue and Purple flowers. Yellow flowers. 



P. algida, Adam P. luteola, Rupr. 



P. auriculata, Lam. 

 P. baldschuanica, Fedtsch. 

 P. Olgae, Regel 



Section Nivalis. 



The evolution of this section in Northern Asia is its maximum. 

 We have true P. nivalis, Pallas, and in addition the microforms : — 

 P. Bayernii, Rupr., a white- flowered form from the Caucasus, its 

 leaves beaded along the margin with mealy teeth. P. eximia, Greene, 

 only touches North Asia in Tschuktschiland — its main distribution 

 is through the Aleutian and Kurile Islands. P. turkestanica, Regel, 

 is the P. nivalis var. farinosa of Schrenk, a plant strictly limited 

 to Turkestan. P. longipes, Freyn et Sintenis, grows in Pontus as a 

 strikingly robust form even in this robust alliance, and it has large 

 flowers with long drooping pedicels. Lastly, P. pumila, (Regel) Pax, is 

 the dwarf P. nivalis of Tschuktschiland. 



I may add here that the white-flowered plant commonly grown 

 in gardens as P. nivalis is a form of the European P. hirsuta, 

 All. It is figured by Sims in the " Botanical Magazine " of 1809 under 

 the name nivea, and ought to be known by that name. It has no 

 relation to the true P. nivalis, Pallas.

Section. 

 P. cuneifolia, Ledeb. 



Section Sredinskya. 

 The specific name of P. grandis, Trautv., describes a foliage character 

 in this Caucasian species which is diagnosed by the form of corolla — 

 cylindric tube with linear petals. It is an easily-grown plant by
