Roots composed of many slender, wiry, dark brown, branching Ghee Cau 
dex slender, filiform, creeping, somewhat downy, scarcely distinguishable 
from the fibres of the root. Fronds several together, tufted, from two to 
four inches high, almost destitute of a stipes, linear, attenuated at the 
base, and scarcely a line broad in the greatest diameter, glabrous, blunt- 
ly dentato-serrate at the margin, furnished with an evident midrib, and, 
arising from this, several parallel oblique simple nerves. 
From the uppermost of these nerves appear the oblique oblong sorz ; one on 
each nerve, which, as they advance in age, become confluent, and then 
appear to occupy the whole of the under side of the extremity of the 
frond, which becomes somewhat contracted and less distinctly toothed. 
This is the only difference between the fertile and the sterile frond. 
Capsules brown, annulated and pedicelled. 
This pretty little fern is d-scribed by SwaRTz as an inha- 
 bitant of Jamaica, growing among mosses at the roots of trees. 
The Reverend Lanpspown GuiLpiné finds it in St Vin- 
cent’s, on the Souffriére and other mountains, abundantly, and 
has communicated the specimen from which the accompanying | 
figure was taken.
