Trichomanes — Prom the Greek, soft liair. Krausii — Named 



after Dr. Kraus. 



A SMALL, elegant, creeping Fern, growing on the trunks of 

 trees. 



Native of Guiana, Trinidad, Dominica, St. Vincent, Jamaica, 

 Guadaloupe, Porto Rico, and Berbice. 



Fronds profoundly pinnatifid almost to the rachis, oblong 

 in form, segments linear-oblong, obtuse, sinuate, occasionally 

 again pinnatifid; stellato-pillose in the sinuses; sessile or 

 stipitate; somewhat wedge-shaped at the base. 



Involucres subcylindrical, base attenuated, much sunk in the 

 frond, two-lipped, the lips being semiorbicular, exserted, of 

 large size, and usually tipped with red. 



Caudex creeping and very tomentose. 



Fronds from one to three inches in length. 



Requires a humid airy atmosphere, ranging from 50° to 75° 

 of temperature. 



My thanks are due to Mr. Smith for plants of this Fern.
