t 1 rands forming intricated mass, erect, rising from creeping segments- 

 which are fixed to the substratum by small radical discs, flat, irregularly 

 dichotomus, with or without short stipe, 5-7 cm. high. Fronds rather 

 variable in shape, more or less dichotomous, but sometimes subpinnately 

 branched. Segments patent with round axils. Branches adhere to each 

 other at the places where they come in contact by forming root-like 

 discs or simply by fusing together; they often become fixed to substra- 

 tum by radical discs made on their apices and they emit, both from 

 margins and surfaces, filiform or more or less broad and shortly 

 stipitate segments, which more and more increase the intrication by the 

 process just spoken about. Segments vary in breadth from 2 to 5 mm., 

 some broadly linear, others almost leafy, while in extreme ones almost 

 filiform (fig. 6). Apex of segments oblong, spatulate, ligulate or pointed. 

 Fruits of both kinds unknown. Colour purplish-red. Substance soft 

 CMrtiljginous and the plant does not adhere to paper in drying.
