BRITISH FERNS. 
leaflets oval. The stems are quite black, hence the spe- 
cific name. Its home is Mexico. 
Gymnogramma ochrctcea . Ochry Gymnogram. A fine 
member of the golden group. The fronds are of a large 
size, evergreen, the leaflets bright glossy green above, 
full yellow beneath, but the powder is less freely scat- 
tered. Very easy of cultivation. 
Gymnogramma ruj a. Red-haired Gymnogram. Fronds 
pinnate; stems red and hairy ; veins red. This contrast 
in the colouring of the stem and veins gives a varied and 
pleasing appearance, and atones for the absence of the 
golden and silver powder so much valued in other species. 
It is a native of Mexico. 
Gymnogramma tomentosa. Downy Gymnogram. Fronds 
somewhat triangular in form, bipinnate ; leaflets sharply 
pointed, veined with red, the veins much forked, hairy ; 
stems half the length of the frond, black. A delicate 
and beautiful Brazilian species. 
Gymnogramma cheer ophylla. Chervil-leaved Gymno- 
gram. Fronds bi- or tripinnate, delicate in texture, of pale 
colour, in form resembling those of Cystopteris montana. 
We have it from the West Indies and South America. 
Polypodium effusum. Spreading Polypody. Fronds 
tripinnate ; leaflets small and elegant, of a triangular 
form, serrated. The fern attains a height of 5 or 6 feet, 
and the feathery form of the fronds, together with their 
arching habit, gives a great charm to the group. Caudex 
creeping. A Jamaica fern. 
Polypodium longipes. Long-footed Polypody. Fronds 
pinnatifid, cut into seven segments, each segment narrow 
and tapering, evergreen, feet long, but the naked 
stem occupying more than half the length ; caudex creep- 
ing. A noble Indian fern.
