NOTES ON A COLLECTION OF FERNS FROM THE 

 DOMINICAN REPUBLIC.! 



BY WILLIAM R. MAXON. 



In November, 1920, Dr. W. L. Abbott revisited the Domini- 

 can Republic, spending the period to May, 1921, in an investi- 

 gation of the natural history of the Samana Peninsula and of 

 the region lying between Sanchez (at the head of Samana Bay) 

 and Puerto Plata, on the north coast. Two weeks was spent 

 at Sanchez; three weeks in the vicinity of Samana, a town on 

 the south coast of the Samana Peninsula about 20 miles east of 

 Sanchez, and on the mountain known as Pilon de Aziicar; 

 seven weeks at several stations along the railroad connecting 

 Sanchez and Puerto Plata, among which were Villa Riva, 

 Pimentel, Cotuy, Mao, and Navarrete; two weeks in the 

 easternmost portion of the peninsula, in visiting Las Cacaos, 

 Rojo Cabo, and Cape Samana; one week on the south coast 

 of Samana Bay, in the vicinity of San Gabriel; and one week 

 in the region of Old Heart River, in the north-central part of 

 the peninsula. 



On this trip Dr. Abbott's principal attention was given to 

 collecting plants, of which about 4,000 specimens, representing 

 1,460 numbers, were obtained. About one-fifth of the collec- 

 tion consists of ferns and fern allies, these for the most part 

 well known species of the Greater Antilles. Notes on some of 

 the rarer species, with description of a well marked new species 

 of Anemia, are given herewith. 



A full report will shortly be published upon a much larger 

 collection of pteridophyta collected in Haiti by Mr. Emery C. 

 Leonard, who assisted Dr. Abbott in his biological exploration 

 of that country in the first half of 1920.
