Pentstemon humilis (N.W. America). 
Treat like Pentstemon glaber. 
Petrocallis pyrenaica, seé Draba pyrenaica. 
Philesia buxifolia, syn. magellanica (Chili, etc.). 
A shrubby plant suitable for the dry side of a 
bog-garden, where it will have the full benefit of the 
sun and be sheltered from the north. Plant in hard 
fibrous peat and white sand, with a small portion 
of rough loam mixed well with these. In winter a 
little protection with bracken is very beneficial to the 
buds. Every second year it is a good plan to layer 
the plant down, pegging each shoot close to the 
ground and covering over with peat and leaf-mould, 
as in this way it will be induced to root freely from 
the stems and soon form quite a nice bush. 
Phlox ameena (Virginia to Florida). 
Treat like Phlox procumbens. 
Phlox divaricata, v. canadensis (N. America). 
The true form of this beautiful variety grows 
upright to a height of about gin., and flowers in a 
neat, compact truss. Plant on the flat with a south- 
west aspect, in deep, sandy loam. This plant must 
be well protected from slugs and snails, which are 
exceedingly fond of it. Nothing is so efficient for 
this purpose as a sprinkling of moderately fine steel 
filings, such as are produced by machine turning and 
boring, placed a little way from the collar of the olant. 
Phlox procumbens (Gar. Hyb. ?). 
A pretty but not free-flowering plant, requiring 
a sunny position with cool bottom, on the flat or on
