Has. Tasmania, Mr. Gunn.—Allied to W. multifida, but the 
diameter of the frond is thrice as great, and the ramelli 
proportionably thicker.

Has. George Town, Mr. Gunn.—The favelle of this plant 
are involucrate, but not terminal. In this last respect, there- 
fore, it departs from the character of the typical species.

Has. George Town, Mr. Gunn.—The fruit is fiit etiniai 
a desideratum, and the genus may therefore be questioned. 
The habit is very similar to that of Dasya bolbochete, while 
the structure and mode of branching are more like those 
of W. comosa, on a much larger scale. The stems are 
6-12 inches long, and as thick as — twine ; the sie am 
2-3 lines in length.
