39 
PARNASSIA californica —Shining green, kid¬ 
ney or heart-shaped basal leaves and 
large saucer-shaped white flowers on 10 
to 12 inch stems. For a shady spot with 
moist, peaty soil. 35c each. 
PENTSTEMON —This American genus fur¬ 
nishes us with the finest material for 
rock and wall work. The requirements 
for their success are simple: a gritty or 
stony soil, without any fertilizer except¬ 
ing leaf-mold, perfect drainage and full 
sun. Amid the almost universal con¬ 
fusion of names in this family, it is diffi¬ 
cult indeed to be sure of names. Insofar 
as possible, plants listed below have 
been identified by comparison with herb- 
barium specimens named by National 
Museum botanists, or by direct identifi¬ 
cation by them of specimens.
