it should be top-dressed in the manner 
described for gramznzfolium, only sand and a 
little loam should be used. It roots freely 
from the old wood. L. prostratum. A well- 
known species, which likes a north-east or north- 
west position, but must be sheltered from the 
wind on a sloping bank. Compost: rough 
loam, peat, leaf-mould, and grit or sand in 
equal proportions. The place should be well 
drained, but the drainage should be 8in. or 
10in. from the root of the plant. A little top- 
dressing in the spring will improve it very 
much. L. ¢inctorum. A very rare plant, and 
not often seen in gardens; in fact, an almost 
extinct species. This requires special treat- 
ment. It should be kept as dry as possible 
during the winter on a south part of the 
rockery, where a stone hangs over from the 
north. Beneath this stone will prove a very 
suitable position for it. Give it a deep, sandy 
loam, leaving plenty of room for the tap root 
to descend amongst the rocks, and it will stand 
any amount of burning in the summer when 
once established. If a nice compost is put 
round the plant in the spring it will no doubt 
ripen the seed. Young plants may be obtained
