is possible that future investigation may show some form of asexual 
reproduction in this order. Hooker’s description of the genus is as follows: 
“ Root scutate. Frond stalked, dark olive-brown or black, flat, expanded, 
very thick and coriaceous or honeycombed transversely internally, palmate 
or pinnate, without distinct organs. Fruit dioecious. Conceptacles 
scattered over the whole frond in the cortical stratum, containing either 
obovoid subsessile spores or branched filaments bearing obovoid antheridia " 
(1867, p. 654). 
The genus belongs to the Southern Hemisphere, and usually two

distinct species are recognized, D. antarctica 
often 30 ft. long, forming an immense flabellate palmately lobed laciniated 
lamina, contracted at the cuneiform base into a short stipes as thick 
as the wrist; segments or thongs often lin. thick, honeycombed in-

Island, and subjected to even severer conditions thàn those met with “73 
on New Zealand coasts, has its lamina much more divided than typical : 
D. antarctica, a fact which may add further weight to the suggestion that 
the form of the plant depends on the habitat. 
Distribution. Б 
As regards the distribution, Skottsberg reports it from central Chile to es 
Cape Horn, Falkland, Kerguelen Islands, New Zealand, sim Auk —
