beneficial, serving to keep the plant warm in winter 
and to retain moisture during hot sunshine. 
Androsace lactiflora (Siberia). 
A pretty and useful biennial, which makes a 
very nice companion to Erinus alpinus. If a little 
seed of this plant is scattered on the sunny side of a 
rock it will grow and flower freely, sowing itself year 
by year. 
Androsace Laggeri (Pyrenees). 
Treat like A. carnea. In autumn top-dress with 
sand and leaf-mould. 
Androsace lanuginosa (Himalaya). 
Requires the same aspect and soil as Androsace 
foliosa. This species resembles Androsace sarmen- 
tosa in that it is liable to be injured if standing 
moisture is permitted to rest too long upon it in the 
winter season; but as its leaves are more silky it 
does not suffer so severely in this way. A. lanuginosa 
also differs from A. sarmentosa in not rooting from 
its rosettes. For both these reasons, and from its 
habit, it is placed to best advantage when planted 
immediately behind a stone, over the face of which 
the young growth will trail down and flower freely. 
A. lanuginosa may be pruned back annually, as it 
sends out young growths from the base each year— 
indeed, the old shoots should be entirely cut away 
every second year, for if allowed to remain on season 
after season they become very straggly, and do not 
flower so freely as when young. 
Androsace pubescens hirtella (Alps). 
Treat like Androsace carnea.
