TPJCHOMANES KAULFUSSII. 



Hooker and Greville. 



PLATE LXIII. 13. 



Trieliomanes lucens, Hooker and Geeville, (escl. syn.) 



Trichomanes — From the Greek, soft hair. Kaulfussii — Named after 



Kaulfuss, a celebrated cryptogamic botanist. 



This handsome erect species is from Jamaica, St. Vincent, 

 British Guiana, Dominica, and St. Thomas. 



It requires a very moist firm soil and a humid close 

 atmosphere, with a range in temperature from 65° to 85°. 



The fronds are narrow, approximate, somewhat hairy, suh- 

 bipinnatifid, rachis broadly winged. Segments approximate, 

 horizontal, lanceolate, rigid, lobato-dentate; lobes brief and 

 blunt. Pinna; mostly opposite. 



Involucres abundant, cylindrical, cup-shaped, entirely sunk in 

 the segment, the mouth slightly spreading. Receptacles filiform 

 and much exserted. Stalks hairy; stipes winged; rhizoma 

 thick and very short. 



Length of frond from nine to eighteen inches. Colour dull 

 green. 



My thanks are offered to Messrs. Backhouse and Son, of 

 York, for the frond illustrated.
