- FERNS—Continued. 
*Dryopteris fragrans (Fragrant Fern)— 
Native from Vermont north to Greenland 
and Alaska, it grows on dry limestone 
cliffs throughout Canada, but nowhere is 
it plentiful. Growing from 6 to 10 inches 
tall it has a slight resinous odor and 
proves to be very easy to grow in light 
shade. $1.00 and $1.50 each. 
*Pellaea andromedaefolia—(Coffee Fern) 
One of the most distinct and interesting 
species of our native Ferns. The leaves 
are from 6 to 12 inches long and 3 to 5 
inches wide, and are very different from 
other Ferns, 50c and 75c each. 
P. atropurpurea—Dwarf resistant species 
with grey-green, black-stemmed fronds. 
Requires lime. Not common. §8 inches. 
50c each. 
*P, glabella—A very distinct species, some- 
what on the order of P. atropurpurea, 
but with fronds only 6 inches long, and 
pinnae more rounded. Like atropur- 
purea, likes a little lime. 75c and $1.00 
- each. 
*P, mucronata—(Bird-Foot Fern). Rather 
stiff foliage, shaped like bird track, 8 to 
10 inches long. 50c and 75c each. 
*Pityrogramma triangularis — (Formerly 
listed as Ceropteris triangularis) The 
Gold-Back Fern. The fronds, 6 to 8 inches 
long and 3 to 5 inches wide, are dark 
green above and deep golden yellow be- 
neath. Dry conditions in light shade. 
35c each. 
SHADE FERNS 
camptosorus *rhiscophyllus — (Walking 
Fern.) Usually found carpeting limy 
ledges or boulders in shade although it 
occasionally grows in full sun where the 
foliage becomes a much lighter green. 
In shade the fronds root at the tip in 
the black leafmold to produce many new 
plants, thus making a thick mat. 50c ea. 
cyrtomium falcatum—A very rare Fern 
from Japan, hardy in northwest with a 
little protection, but usually used as 
house plant, being one of the few species 
which will thrive under ordinary house 
conditions. Requires a little shade in 
summer, protection from wind and leaf- 
mold or peaty soil. The large, thick, 
glossy foliage makes it an excellent Fern 
for decorations. 12 to 18 inches. $1.50 
each. 
*Lygodium palmatum (Climbing Fern)— 
Leaves 2 feet or more high, bearing pairs 
of cordate-palmate pinnules 1% to 2 
. inches long, on short petioles. Massa- 
chusetts to Florida and Tennessee. Very 
hardy, requiring a light moist soil and 
light shade. $1.00 each, 
polypodium *scouleri — (The Leathery 
Polypody.) A rare fern with very leath- 
ery, evergreen fronds with rounded 
pinnae and unusual, golden sori on the

others, as noted. 
*P. acrostichoides — (Christmas Fern) 
Leaves in dense crowns, 10 inches high. 
Very easy. 50c each. 
P. andersoni—A very rare species, some- 
what tall for the rockery. the rather 
broad, lacy fronds being from 18 to 24 
inches long. Light shade. $1.00 and $1.50 
each. 
P. brauni—Another species which is rather
