24 Alpine Plants. 
so free that it becomes insufficiently ripened to 
withstand the damp of winter. 
Arenaria stricta (S.W. Europe). 
This species, unlike the other Arenarias, requires 
a damp, peaty soil, and does well on the shady side 
of a bog. 
Arenaria tenuifolia (Alps). 
Treat like Arenaria rosani. 
Aretia Vitaliana, sce Douglasia Vitaliana. 
Armeria czxspitosa (Spain and Portugal). 
A rare little plant, but of very easy culture, 
doing equally well on the flat part of the rockery, or 
wedged tightly between stones in full sun, in a deep 
bed of two parts grit and sand to one of loam. If 
this plant is put on the level, it is wisest to place a 
stone immediately behind it, so that it may be kept 
firm until established. Should the foliage become 
brown at any time, feel whether the cushion is firm 
or not, and if it seems at all loose, take the plant out 
at once and examine the tap-root ; should a small 
white grub then be found in the heart of the root, the 
plant must be removed to some other part of the 
rockery, or if put back in the same place the grubs 
must be destroyed, the old loam taken out, and fresh 
loam substituted in its place. 
Armeria juncea, syn. setacea (S. France). 
This species make a nice companion for the 
above, and does well in a south aspect, in any poor 
loam, thriving best, however, on sandstone. 
Arnebia echioides, s¢¢é Macrotomia echioides.
