JENNINGS: FERNS OF THE ISLE OF PINES 135 
were found Lygodium cubense H. B. K., clambering over 
low shrubbery or twisting itself into dense mats; a Lind- 
saya, rather near L. portoricensis Desv., but small; and 
more of the same Trichomanes found in the upper Los 
Indios drainage. 
One day was spent on the coral-limestone peninsula 
which ee the southwestern extension of the island. 
Practically the whole trip was along a trail through a 
tropical jungle where perhaps half of the vegetat on con- 
sists of species not seen in the northern portion on the 
island, but no ferns were seen there 
The last two days of field work were spent in the east: 
central portion of the island, where the soil and vegeta- 
tion are quite similar to those of the Nueva Gerona district. 
On the palm trunks along the banks of the upper Rio de 
Santa Fé, south of the town of Santa Fé, Phlebodiwn— 
_ aureum (L.) J. Sm. was quite common. Near the mag- — 
 nesia springs at Santa Fé the steep banks of the short 
___ Yavines !eading to the river have been cleared of most a 
the shrubbery, but the larger trees have been left stand- 
ing, and along the springy shaded banks of these ravines 
_ ferns were abundant. Within the space of pane not 
_ over two hundred feet square were collected Dryo teris 
sancta (L.) Ktze., Tectaria trijoliata (L.) Cav. [Aspidiu 
-_ trifoliatum (L.) Sw. Adiantum cristatum L., Dryoptert 
patens s (Sw. ) Ktze., and Ceropteris | pectic (Cav.) Li
