Frond dendritic, standing with a short, thick, firm and subcylindnc- 

 al stem, which firmly adheres to substratum by thick, stunted, root- 

 like branches, attaining the height of 5-6 cm. Stem which attains for 

 the most part a thickness of 2-3 mm. soon dissolves above into 

 many slender branches. Branches, which are naked below, are 

 densely loaded above with short ramuli on all sides. Ramuli are 

 somewhat fusiform in shape, rising from slightly narrowed bases and 

 tapering into sharp points. Cystocarps unknown. Tetrasporangia 

 formed in upper portions of ordinary ramuli. Colour when fresh 

 pinkish-red with whitish lustre, changing into dark brown on drying. 



Structure of frond : Frond internally consists 01 nve pericentral 

 cells, which are more or less densely surrounded by roundish angular, 

 subcortical cells, and externally by an epidermal layer. The structure 

 of stem is more dense than that of ramuli which are more or less 

 loosely constructed, leaving larger lacunar spaces, in which filamentous 

 cells are often observed. Around the growing apices of branches of 

 every order, there arise on all sides deciduous hair-leaves, which have 

 their origin on basal cells derived from axial cells. The position 

 of a hair-leaf, after it has fallen off, is easily to be seen in surface- 

 view of branches as it presents a roundish cell as its scar, while the 

 remaining cells neighboring it are elongated and somewhat reticulated. 

 As that portion becomes thicker, the scar-like cell will be accompanied 

 by two or more similar, roundish cells which are arranged in a linear 

 longitudinal row.

Kuetzing in 1866 described the plant in question collected at 

 Wagap in New Caledonia under the name of Lophuva a/rmata. On 

 studying the plant which was collected by me at the Cape Bo, I found
