158 BALFOUR—NEW SPECIES OF PRIMULA. 
The absence of meal from the flowers seems to be made up for 
by the development of viscidly-glandular short hairs over the 
calyx inside and out, and the margins of the calyx are fringed 
also with long glandular hairs. Concurrently the calyx is very 
thin and membranous. In P. gracilenta the calyx has a close 
covering of non-glandular hairs on the outside and is bare of 
them inside. One may say P. gracilenta is the nearest ally in 
the Section to P. conica. In addition to the calyx character, 
P. gracilenta is readily differentiated by the apiculate corolla- 
lobes. The behaviour of P. conica in cultivation so far suggests 
treatment for it not different from that of other members of 
the Section. The plant was introduced by Mr. Williams of 
Caerhays Castle through seed collected by Mr. G. Forrest, and 
flowered for the first time in 1916 with Messrs. Wallace of 
Colchester and also at Edinburgh.
