114 ORNAMENTAL GARDENING 



Osmunda spectabilis and 0. 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 swartzii. 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 on decaying 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. 



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- 

 staUt 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.
