CHEILANTHES SILIQUOSA 
FERNS—continued 
*Ruta-muraria (cryptolepis) —(Wall Rue) —A tiny evergreen 
Spleenwort from eastern limy cliffs and boulders and widely 
distributed throughout the Old World, especially on old 
walls. Minute tufts of 2 inch ashy-green fronds which have 
few, roundish, toothed divisions and green stalks. Rare in 
gardens, distinct and not easy. Lime. Pots, $1.00 and 
Sileo O: 
CAMPTOSORUS *rhizophyllus (Walking Fern) —In the East it 
often carpets 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. Undivided tapering fronds to 9 inches. 
Requires lime. Pots, $1.00 and $1.25. 
CHEILANTHES “*“alabamensis—A distinctive southern Lip Fern 
with rather dark green, twice-pinnate blades and black 
stipes. 10 in. Some lime and perhaps a little protection in 
cold sections. Pots, $1.00 and $1.25. 
*gracillima (Lace Fern)-—A compact, tufted rock fern mostly 
from high elevations on western mountains. 4 to 8 inch 
fronds, twice-pinnate, with crowded segments, woolly be- 
neath and dark brown stalks. Pots, 75c; field, $1.00. 
**Janosa—A hardy species much like alabamensis in outline but 
covered with rusty hairs and having brown stipes. 12 to 15 
insLOtsae a Graticlds OO: 
*siliquosa (PELLAEA densa)—Very different from thé Lip 
Ferns and still shifted from one genus to another. Dark 
green fronds with long, purplish-brown stipes and thrice- 
pinnate blades with pointed segments. The fruiting fronds 
have narrower segments and form an interesting central 
tuft. Evergreen and compact, to 10 inches. When estab- 
lished will withstand drought and sun. Pots, 75c; field, 
$1.00. 
DRYOPTERIS *fragrans—Mostly an Arctic or sub-Arctic lime- 
stone (?) cliff-dweller and nowhere common. Evergreen 
fronds to 10 inches, twice-pinnate with tiny, regular divi- 
sions. Covered with brown scales beneath and producing 
a haunting, aromatic odor, especially when young. Difficult 
to propagate and stock limited. Not easy and a challenge 
to collectors. Pots, $2.50. 
LYGODIUM palmatum (Climbing Fern) — This fern actually 
twines and climbs! It should be planted beside an open 
twiggy shrub so its wiry, light brown, 3 foot stems can 
thread their way amongst the branches. Actually each 
shoot of the “‘vine’’ is a single frond. Attached to the thin 
stipes are pale green ‘’fronds’’ which are palmately lobed. 
The Climbing Fern is a rare, local, eastern native. It re- 
quires a very light, intensely acid soil and moisture. Charm- 
ing and unusual. Pots, $1.50. 
PELLAEA *andromedaefolia (Coffee Fern) —An interesting spe- 
cies from southern Oregon and southwards with rather 
bluish-green, broad blades and pale brown stipes. The 
many small divisions are rather blunt. Evergreen to 2 ft. 
Pots, $1.00; field, $1.50. 
*atropurpurea (Purple Cliff Brake) An evergreen native of 
limestone ledges and boulders. Pale, gray green fronds 
leathery in texture. Few, broadly linear divisions and deep 
purple stems to 1 foot or more. Requires lime. Pots, 75c; 
field, $1.00. 
*mucronata (Birds Foot Fern) A -distinctive southwestern 
fern rarely seen in gardens. The stiff, evergreen fronds 
are light blue green and sometimes reach 2 feet. They are 
much-divided into small, pointed segments which resemble 
a three-pronged bird’s track. Pots, $2.00; field, $2.50. 
PITYROGRAMMA *triangularis (Gold Back Fern) —One of the 
best western ferns. Broadly triangular, twice-pinna*2 
fronds, dark green above and covered with golden yellow 
or sometimes whitish powder below. 6 to 8 in. When estal- 
lished will tolerate drought. Pots, 75c; field, $1.00. 
POLYPODIUM *Scouleri (Leathery Polypody)—A fern of the 
west coast which hangs from forks and trunks of old trees. 
The very leathery, dark green fronds, once-pinnate, have 
blunt segments. The large, golden sori on the under surface 
are conspicuous. | ft. Plant in pure leafmold and/or rotted 
wood and keep moist. Probably needs protection in cold 
climates. Rarely offered. Pots, $1.25. 
AMERICAN FERN SOCIETY—Those interested in the study of 
Ferns are urged to join the American Fern Society, Inc., 
the official organ of which is the American Fern Journal, 
an illustrated quarterly. Dues, $1.50 per year, including 
four issues of the Journal. Send dues to Mrs. Elsie G. Whit- 
ney, Secy., 274 South Main Ave., Albany, N. Y. 
GAULTHERIA—Belongs to the Ericaceae and requires a cool 
root run and acid soil, with shade or light shade and mois- 
ture during the dry season. Plant in peaty, woodsy soil. 
Fine as shrubby groundcovers under Rhododendrons or 
Azaleas or in the woodland garden. 
*humifusa—A very compact evergreen creeper from the high 
Cascades with small, rounded, leathery leaves, white urn- 
shaped flowers in mid-Spring, and scarlet “‘berries’’ later. 
1 Y2 in. Hardy but not easy. Pots, $1.00; field, $1.50. 
*nummularifolia—Procumbent evergreen with reddish, hairy 
BY stems and small, oval leaves, dull green above. Rarely 
flowers but a wide-spreading groundcover for mild cli- 
mates. Rare Himalayan plant. Pots, $1.00; field, $1.50. 
*nummularioides—Very much like the above but more vigor- 
ous and with larger, conspicuously veined leaves. A few 
white, pitcher-shaped flowers from the leaf axils followed 
by bluish-black fruit. 6 in. Himalayas. Groundcover for 
mild sections. Pots, 75c; field, $1.25. 

DRYOPTERIS FRAGRANS 
*ovatifolia—A slender, much-branched shrub with prostrate 
or spreading branches, 8 to 12 inches long, the young twigs 
reddish-pubescent. White flowers and later, bright scarlet, 
flattened fruits. 5 in. The handsome, evergreen foliage 
makes a fine, hardy cover. A native of our western moun- 
tains. Pots, 75c; field, $1.25.
