Plants varying in length to about 21 cm., as a rule thickly calcified. Rooi mass bulbous 

 to elong .■ Stipes simple, varying to 15 mm. long, and 5 mm. thick, flattened abo\ 



1 rond stalked, very variable in form, from a cuneate base usually suborbicular-flabelli- 

 form, simplr at first, becoming repeatedly and irregularly proliferous from the margin and 

 sometimes from the surface, zoned, often striate or plicate; proliferations broad or narrow, 

 ently abundant and overlapping, repeating the character of the main frond; varying in 

 colour from green to green ish-white or greenish-brown ; usually solidly calcified, smooth to 

 margin entire, (ir more or less lobed. 

 Frond-filaments more or less parallel, radiating upwards, pluriseriate, separated, not con- 

 tringly dichotomous, without supra-dichotomial constrictions, bearing lateral branchlets 

 ual length, at irregular intervals, cylindrical or sometimes thinner above the base, 

 ilately or cymoidly branched above. Apices of lateral appendages obtuse, 

 ipitate, contiguous, combining to form a tough close cortex.
