TEICHOMANES. 115 



T. SPICATUM (Spike -bearing). The name is given in 

 reference to the fertile fronds, which are quite different from 

 the others, being reduced almost to a midrib, bearing a line of 

 the cup-like receptacles containing the spores on either side. 

 The sterile fronds are shorter and broader, 3 inches long, 

 divided almost to the midrib. It grows in tufts. There is 

 another species called T. elegans, which resembles this one 

 much in form and habit, but is rather larger. 



T. TEICHOIDEUM (Hair-like). A most interesting little gem. 

 Tne fronds, which are about 3 inches long, are cut up into 

 hair-like divisions. It has a creeping rhizome, and so may be 

 increased by division. 



There are now a great number of these Filmy Ferns ; 

 perhaps as many as fifty species in cultivation. Mr. Back- 

 house has introduced many from Chili, the West Indies, and 

 other parts. M. Linden has added some from the Philippine 

 Islands ; and Mr. R. Sim, and other nurserymen, have obtained 

 many from New Zealand and elsewhere. There is not one 

 among them all but is well worth cultivating. 



This concludes the list of Stove Ferns. We do not by any 

 means consider it a complete one, because we have endea- 

 voured only to notice and describe those that are either 

 remarkable for their beauty, or for being exceedingly curious, 

 or singular. Generally, we have mentioned the height they 

 grow ; and, consequently, growers that have plenty of room 

 may strive to procure them all, whilst others that have only 

 small space may choose the smaller-sized species.
