260 Craib— Primulas of Petiolaris-Sonchifolia Section. 



specific rank only two more of the varieties of P. petiolaris, viz. 

 var. sulphurea and var. Stracheyi, both from Kumaon. Up to 

 the end of 1913 we find that four of Hooker's seven varieties of 

 P. petiolaris had been raised to specific rank. The varieties still 

 remaining at this time and up to the present year are var. 1 

 petiolaris proper, var. 2 nana, and var. 7 scapigera. In var. 1 

 Hooker included probably only one species, viz. the true P. petio- 

 laris from Nepaul. In var. 2 he included, according to the 

 writer's views, six or seven species, and in var 7, two species. 



Last year Professor Balfour described from Yunnan P. taraxar 

 coides, a plant closely allied to P. sonchifolia. 



In course of publication there is also P. vernicosa from Yunnan 

 and Upper Burma, which may be regarded as the Eastern 

 representative of the Sikkim P. Hookeri. 



The material consulted in the elaboration of the present 

 paper consisted of the specimens preserved in the herbaria of 

 the Royal Botanic Gardens at Calcutta and Edinburgh, and the 

 Royal Gardens, Kew, and to the responsible heads of these 

 departments I beg to record sincere thanks for kindly placing 

 the specimens at my disposal. To Professor I. B. Balfour, F.R.S., 

 I am also much indebted for useful constructive criticism during 

 the progress of the work. M. F. Gagnepain of the Paris her- 

 barium has also kindly supplied very useful critical notes on 

 several of Franchet's species, the types of which were not 

 examined by me. To Mr. S. A. Skan, Royal Gardens, Kew, 

 I am also indebted for references to and quotations from 

 literature not otherwise available.
