face of the rock; planted thus it forms quite a 
compact carpet. Sand and leaf-mould as a 
top-dressing added once or twice a year are 
very beneficial to the young roots. There isa 
white form of the above, which is very rare. 
For it similar treatment to zana is required, 
but it is not quite so hardy, and must be 
sheltered from the wet (during winter) and also 
from the north winds. G. alypum (South 
Europe). A very interesting and rare Alpine. 
Unlike the above, it grows bush-like and bears 
larger flowers on long stalks, requiring a more 
sheltered place in full sun. Plant in a 
well-drained part in rough loam, with a little 
hard peat added and sandy grit—two parts 
loam, one part grit, and one peat. If the 
climate is in any way inclined to dampness, 
peat should not be used, but a little limestone 
may be added in its place. There are other 
species well worth growing, which are of easy 
culture ; ordinary garden loam and sand in 
a sunny place suit them well. 
GNAPHALIUM LEONTOPODIUM (As of 
Europe), perhaps better known by the name 
of EDELWEISS. In many places this is found 
difficult to grow, doubtless owing in some
