40 BALFOUR—NEW SPECIES OF PRIMULA. 
Afghanistan. Kurrum Valley. Harsukh. No. 14,931. In 
Herb. Duthie. 
Aitchison says of this plant, which he places asa variety of 
P. rosea, Royle: ‘‘ This variety has each flower supported on 
a long slender pedicel, and the tube of the corolla is longer 
and narrower than that of the type.” This is a just diagnosis, 
and the plant, whilst of the P. rosea, Royle, aggregate, is so 
distinct that its specific distinction is warranted. See p. 23.
