Herb. Watt. — 
A remarkable species of the series of which the longest known 
species is the Nepalese P. rotundifolia, Wall. Sir George Watt 
first recognised the distinctness of the plant, marking as a new 
species in his herbarium a specimen collected at Lhasa by Capt. 
Walton when serving with the Tibet Boundary Commission in 
1g04. This plant has flower. Sir George Watt says: “cf. 
P. rotundifolia, Wall., but flowers yellow and petals contracted 
into a claw. Prof. Lipsky has shown me a good specimen in 
flower collected in Central Tibet, and in Kew Herbarium there is 
a sheet collected by Mr. St. G. Littledale also in C. Tibet.” I 
have seen Mr. Littledale’s specimen in the Kew Herbarium and 
also one of his collecting in.the Calcutta Herbarium. The only 
flowers I have seen are on Capt. Walton’s plants. Sir George 
Watt did not name the plant. The Kew specimen has a MS. 
name attached to it by Prof. Lipsky in 1905, whether before or 
after Sir George Watt’s diagnosis I do not know, but the name 
has not been published, and with Sir George Watt I give the 
mame above. 
The plant shows conspicuously the multicipital habit of so 
many of its allies, with the dry mass of withered leaves and 
scapes underlying the living. In this perhaps more than in 
any other series of suffruticose Primulas the “dry” method 
of rotting of old members is marked by curious curvature 
and contortion of the petioles in contrast with the stiff
