■^"••' TEICHOMANES PYXIDIFERUM. 



The fronds oblong-ovate, bi-tripinnatifid, membranaceous, 

 shining, and almost transparent; segments linear, firm, flat, 

 smooth, and entire, the apices frequently emarginate. 



Stipes winged. Length of frond from three to six inches. 



Involucres solitary, subcylindrical, the base attenuated, axillary, 

 wholly buried in the segment; mouth broadly concave, scarcely 

 two-lipped; the receptacles filiform, of great length, and 

 considerably exserted. 



Requires a rather close humid atmosphere, with a temperature 

 varying between 55° and 75°. 



There are several varieties more divided than in the normal 

 form; in one the segments are crowded, and in another they 

 are broader. 



My obligations are tendered to Mr. Smith, of Kew, for fronds.
