Biscaynianum D. C. Eaton). Fully entitled to specific rank. 

 Abundant on limestone bluffs, back of a mangrove swamp at 

 Punch Bowl, Miami. Half-way between the next two, with 

 which it grows. 



Asplenium dentatum L. Lime-rock walls and large sink-holes. 



Asplenium myriophyllum Presl. Similar places to the last, 

 but mostly in small sink-holes. Found with the last only at the 

 Punch Bowl. 



Asplenium serratum L. In several hammocks from Miami to 

 25 miles south. 



Blechnum serrulatum Richard. Mucky hammocks on the 

 border of the Everglades. 



Isoetes Haccida Shuttlew. In shallow water and moist soil on 

 the border of the Everglades. Not common. 



Lycppodium Caroliniqnum L. Wet sand near a swamp. Ft. 

 Lauderdale. 



Lycop odium Chapmanii Underw. Wet sand. Ft. Lauderdale 

 and Miami. 



Meniscium reticulatum Sw. On cypress-knees in a swamp 

 bordering the Everglades at the Miami water works, Alapattah. 

 Heretofore known from North America only from a few pinnx 

 collected in June, 1903, in a cypress-swamp on the west coast by 

 J. E. Layne. This, after Acrostichum lomarioides, is our largest 

 fern, reaching g x / 2 feet in height and 3 feet in breadth of frond. 

 The largest pinnae bear proliferations at base that sometimes 

 bear fruiting fronds. 



Nephrodium amplum Baker. This very fine fern, which might 

 be classed with the tree ferns on account of its stout caudex x / 2 ft. 

 high, I first found at Costello s hammock, 12 miles south of 

 Cutler, when in company with Dr. Small and Mr. J. J. Carter. 

 It had been found there the previous day by Messrs. Soar and 

 Simpson, who had tried to connect with our party. We later found 

 it in Ross' hammock and in a smaller one two miles further 

 north. 



Nephrodium rcptans Diels. (Phegopteris rep tans Sw.). Lime- 

 sinks of all the hammocks in the pine-woods, 12-14 miles south 

 of Cutler. This has the venation of Nephrodium molle and 

 nearly always has a fringed indusium. As the genus Pliegopteris 

 is founded on the absence of indusium, it seems best to place this 

 species in Nephrodium.
