species has been grown in pots as well as planted out 
under glass in a house devoted to rock-plants, P. pulvinata 
has proved easy to cultivate at all stages. It does not 
appear to be fastidious as to soil; a good loam with a 
liberal supply of broken limestone or crushed potsherds 
and sand gives satisfactory results. It is not yet possible 
to say from experience that it will prove entirely hardy 
out of doors, but in the cold greenhouse it has withstood 
fifteen degrees of frost without suffering damage. Being 
evergreen, growth appears to goon during the whole year. 
Mr. Harrow, to whom through Professor Balfour we are 
indebted for this information, regards it as probable that 
the best hope for success out of doors will be where the 
plant is grown in a situation where the water, of which it 
requires at all seasons a fair amount, can drain away 
quickly from the collar and roots, At Kew the plant has 
been accorded the treatment suitable for P. Forrestii with 
satisfactory results. The great difficulty, as Professor 
Balfour points out, with the Primulas of this group, 
and the circumstance that militates against their satis- 
factory cultivation as garden plants, is winter damp. 
These species show a crisp type of withering of their 
leaves, and while they can resist a moderate amount of 
top-water, cannot live if their withering leaves become 
sodden.
