Sprike-fruited Bristle-Fern. 
Trichomanes ({ Féea) spicatum; caudex elongated, subrepent, clothed with 
long, descending, wiry radicles; stipites tufted; sterile ones short, one to 
three inches long ; fertile ones three to five inches long ; fronds of two kinds, 
sterile ones four to five inches long, broad, lanceolate, membranaceous, 
deeply pinnatifid nearly to the rachis with close-placed, subhorizontal, oblong, 
obtuse, sinuated, entire segments; veins twice or thrice dichotomous, free, 
and, as well as the costa and rachis, glanduloso-villous ; fertile fronds nar- 
row-linear, formed of a rachis with copious close-placed funnel-shaped 
shortly pedicellate inyolucres, arranged in a distichous spike; receptacle va- 
riously often much exserted, clothed, bearing copious capsules.

Has. Tropical America, in very wet shady places, often found incrusted with epi- 
phytal Jungermannia, etc. ; more frequent in the West India Islands than in 
the mainland, where it seems to be peculiar to the north of that continent ;

A very beautiful species, belonging to a group of the genus 
Trichomanes with dissimilar fronds, and with the sori, in the fertile 
fronds, arranged in spikes ; by many considered a character of 
sufficient importance to form a genus to which the name Fea has 
been given by Bory, in compliment to the very distinguished ptero- 
dologist, M. Fée. Some have even gone further, Bory and Presl 
in particular, and have separated from this group the Zrichomanes 
elegans (see our Plate 2), where the sori, besides being arranged 
in spikes, are united by a membrane, which is not the case here. 
It is true the venation is there anastomosing, but that character
