as this species has a tendency to grow out of the 
ground. If top-dressed carefully it will increase fast, 
and soon make a fine clump. 
Primula involucrata Munroi (N. India). 
This is one of the most easily grown Primulas, 
anda very freebloomer. As sun destroys the delicacy 
of colouring in the flowers, plant in a north aspect, 
using good strong loam with a little leaf-mould, but 
no sand. In autumn, when the leaves go off, top- 
dress and press firmly down. This variety will grow 
on a limestone rockery, but not in limestone soil. 
Primula japonica (Japan). 
Treat like Primula denticulata. 
Primula juribella (S. Tyrol). 
Treat like Primula Clusiana. 
Primula < Kerneri (Styria). 
Treat like Primula Clusiana. 
Primula (spectabilis) Kitaibeliana (Croatia). 
Treat like Primula Clusiana. 
Primula latifolia (Pyrenees). 
Treat like Primula involucrata, adding, however 
a little more peat in the compost used. 
Primula marginata and vars. (Alps of Dauphiny and Piedmont). 
This species may be grown in a similar way to 
Primula Auricula marginata. As this plant has 
a tendency to grow out of its place it must be 
replanted every other year if in a position which 
renders top-dressing an impossibility. Planted on 
the level it should receive a top-dressing every year,
