116 Alpine Plants. 
Silene acaulis and vars. (Europe, Britain, etc.). 
All sun-loving plants, which do well wedged 
tightly between stones in crevices facing full south, 
and which require a very poor soil, as otherwise they 
make too much soft growth in the summer, and this 
gets cut off when the winter comes. 
Silene Elizabeth (Tyrol). 
This species requires to be wedged tightly 
between stones in a sunny place, with plenty of 
depth behind for the descent of the tap-root. 
Silene Hookeri (California). 
Treat like Silene quadridentata. 
Silene Pumilio (Tyrol, etc.). 
Treat like Silene Elizabethe. 
Silene quadridentata (Hab. ?). 
Plant on a dry, sunny bank, wedged between 
stones facing full south, in equal parts of poor loam 
and grit, with a little leaf-mould. In spring a little 
top-dressing about the plant between the stones 
is beneficial. 
Silene Requieni (Greece). 
Treat like Silene quadridentata. 
Silene virginica (N. America). 
This differs from the above-mentioned kinds. It 
will do well on the lower part of the rockery in a 
well-drained place, in good deep loam, attaining, 
when so treated, a height of 18in., and forming quite 
a bush with abundance of flower.
