114 ORNAMENTAL GARDENING 
Osmunda spectabilis and O. cinnamomea are grand ferns which 
grow in low ground and are well worthy of cultivation. 
Acrostichum aureum and A. lomarioides are the largest and most 
robust ferns found in the United States. They grow in brackish 
marshes or in fresh water swamps not far from the sea. The 
former is the smaller of the two. It has a few spurs on the 
stipes and the blades of the fronds are broader than those of 
A. lomarioides: 
Phlebodium aureum is a noble fern which grows almost invari- 
ably among the leaf stalks of the cabbage palmettos. Its large 
fronds are deeply cut; it has creeping, swollen rootstalks, and 
will grow readily if these are transplanted to other palmettos. 
Phymatodes swartzi1. A delicate climbing fern found on the 
north end of Key Largo and in Bauer’s hammock, lower Dade 
County. It has lanceolate fronds and creeps over rocks and trees. 
Campyloneuron phylliditis. A fine fern with thick, char- 
taceous fronds, often three feet long, growing orfdecaying logs 
in the southern half of the state. 
Vittaria lineata, Grass Fern, grows usually on the trunks of 
cabbage palmettos, a lovely plant with linear, dark green fronds, 
which I have found rather difficult to transplant. 
Adiantum capillus-veneris and A. tenerum are lovely and dainty 
ferns, the former inhabiting the northern and the latter the 
southern part of the state. f 
Asplenium serratum is a fine fern resembling a Campyloneu- 
rum, but with broader fronds. They form a beautiful crown 
around the border of the plant. It grows in the southern part 
of the state, mostly on rotting logs, though it is sometimes found 
on the trunks of trees. There are several other species of Asplen- 
ium found in the state, some of which are exceedingly delicate 
and beautiful. 
Dryopteris ampla. This noble fern has a stout, erect root- 
stalk and an immense crown of finely divided, compound fronds. 
It grows in hammocks in lower Dade County and is a true tree 
fern, the only one known in the United States. 
Tectaria heracleifolia is a fine fern with ample, triangular 
fronds, which grows in lower Dade County and is doing well in 
my hammock.
