Trichomanes — From tke Greek, soft hair. Pusillum — Small. 



This species is allied to Trichomanes muscoides, but is smaller 

 in size, being, in fact, a very minute Fern, creeping on the 

 stems of palms and other exotic plants. 



Native of Jamaica and Trinidad. 



The fronds, which are erect, are somewhat cuneate, narrowing 

 into a brief stipes; they are sub-bipinnatifido-lobate, costatc, 

 and crowded together. 



Caudex creeping and tomentose. 



Veins dichotomous and subpinnated. Margins having stellated 

 hairs. 



Involucres two-lipped, half buried in the lobe, cylindrical 

 and narrowing; exserted slightly. 



Cultivation in a damp atmosphere, with a temperature ranging 

 between 55° and 75°. 



My thanks are due to Mr. Smith, Curator of the Royal 

 Gardens, Kew, for plants.
