HARE’S-FOOT FERNS 661 
G. SCHIZOPHYLLA (cut-leaved). Stipes tufted, slender, 6 inches. 
Fronds 1} to 2 feet long, very finely and intricately cut into numerous 
minute pinnules. Stove. 
G. SULPHUREA (sulphur-coloured). Stipes tufted, 1 to 6 inches 
long, upper part powdered. Fronds thrice pinnatifid, 6 to 12 inches 
long, 3 to 4 inches across. Pinnules cut fan-like. Powdered bright 
yellow. Stove. 
G. TARTAREA (infernal). Stipes tufted, 6 to 12 incheslong. Fronds 
1 to 2 feet long, 6 to 12 across, oblong-triangular; twice pinnate. 
Pinnz lance-shaped, the lowest largest. Pinnules blunt, entire or 
nearly so. Powdered pure white. 
G. TRIANGULARIS (triangular). Stipes tufted, 6 to 12 inches long. 
Fronds triangular, 3 or 4 inches either way. Lowest pinnz the largest, 
triangular ; upper lance-shaped, pinnately cut. Powder of variable hue, 
from deep orange to white. Stove. 
All the species of Gymnogramme do well in a compost 
of fibrous peat and sand, well drained, as they require 
plenty of water whilst growing. The fronds should never be syringed, 
as the water gathers in the powder and soon spoils their appearance. 
They require a sunny position if grown under glass. G. schizophylla 
is a beautiful basket plant. G. leptophylla, when once established in a 
fernery, annually reproduces itself from self-sown spores. The others 
may be propagated by dividing the rootstocks and by sowing the spores. 
Some of them have proliferous fronds.

HARE’S-FOOT FERNS 
Natural Order Finices. Genus Davallia 
DAVALLIA (named in honour of Edmund Davall, a Swiss botanist). <A 
genus of about a hundred species of greenhouse Ferns with creeping, 
sealy rhizomes, fronds of varied form, and marginal or roundish sori, 
with a scale-like involucre attached by a broad base and sides. The 
species are widely distributed, and most are evergreen, which renders 
the fronds valuable for cutting. D. canariensis, the Hare’s-foot Fern, 
is the best known; it has been in cultivation here since 1699. Its 
rhizome is densely clothed in brown hair-like scales, and as it creeps over 
the rim of the pot it presents a wonderful likeness to the foot of a hare.
