62 Alpine Piants. 
Gypsophila cerastioides (Himalaya). 
This plant requires a little more attention than 
the other species, and appreciates a full south aspect 
in gritty and poor loam. 
Haberlea rhodopensis (Roumelia). 
Plant with a slight tilt in a sheltered shady 
position between stones in a funnel-shaped cavity on 
a sloping bank facing either east, north-east, or 
north-west, but not wind-swept, in equal parts 
of rough peat and pieces of loam both from 
2din. to gin. square. No sand nor leaf-mould is 
needed for this plant, and no limestone must be 
used on any consideration whatever. Prepare the 
inset between the stones to a depth of 8in. or 1oin., 
taking care to wedge well at the back, so that 
no cavity is left, with 2in. of good loam; make 
this firm, and insert the plant against its surface, 
filling around with the mixed compost and again 
make all perfectly firm. A little fresh compost care- 
fully placed under the leaves and made firm once or 
twice a year is very necessary. 
Helianthemum lavandulzfolium (Mediterranean Region). 
This species is not quite so hardy as some of the 
others, and requires to be planted between stones in 
a more sheltered nook facing full south. A little 
limestone added improves the appearance of the 
foliage. 
Helianthemum lunulatum (Alps.) 
This plant will do well under the same con- 
ditions as Helianthemum lavandulzfolium if protected 
from the north-east wind.
