This well-known and widely distributed species was collected 

 at all the stations, and the large series of specimens shows 

 much variation in size, texture, surface and division. A 

 coriaceous form, with stipe and rachises dark-brown and 

 nearly smooth, with one pair of lateral pinnae which are deeply 

 lobed or compound, the fronds measuring 12 to 14 inches, 

 and the stipes 14 to 16 inches in length, and with the lobes of 

 the pinnae elongated and acuminate, was collected along the 

 La Juana River, and near Camp Menocal. Specimens from 

 the banks of the San Juan River near Castillo have the two 

 lowest pairs of pinnae compound, the lobes of the pinnules 

 deeply crenately lobed, and the rachises short-hairy. The 

 fronds measure 15 to 20 inches, and the stipes 16 to 18 inches 

 in length. The fronds are firm but scarcely coriaceous. A 

 specimen from Boca del Rama has the terminal division of 

 the frond small, but there are 8 pairs of narrow pinnae which 

 are not lobed, but merely very coarsely crenate. The frond 

 is 19 inches long and but 10 inches wide, and is coriaceous in
