that yet much remains to be done for perfecting the elucida- 

 tion of the flora there. I hope that particularly the North- 

 Western regions will be well searched this season." Mr. 

 Moore may well be complimented for these two interesting 

 discoveries, and I hope they will encourage him to still 

 farther prosecute his meritorious observations in that 

 interesting part of the island. Tasmania has only one 

 species of fern peculiar to the island, the remaining fifty-two 

 species are common to one or other of the Australian 

 colonies. Queensland and New Zealand possess by far the 

 largest number of species. Out of the 201 species of ferns 

 found in Australia and Tasmania, only 53 of them, or about 

 one-fourth, are as yet known to exist in Tasmania. This is a 

 small proportion when we recognise what peculiarly favour- 

 able conditions exist in this island for the growth of this 

 most interesting order of plants. 



The following is a description of the two species referred 

 to:— 



Hymenophyllum marginatum (Hook and Grev.), p. 705, Flora 

 Austral., vol. vii. ; p. 57, Hook and Bak., syn. 



Fronds on short filiform stipes, f to 1 inch long ; linear 

 and entire, or once or twice forked, with a central nerve and 

 nerve-like margins not toothed. Sori solitary and terminal. 

 Indusium about h line long and broad, divided nearly to the 

 base into obovoid-orbicular valves. 



On mossy rocks and on trunks of honeysuckle. 



Honeysuckle Hill, Queen River, Tas., T. B. Moore ; Port 

 Jackson, N.S.W. 



Hymenopliyllum malingii, Mett. ; Trichomanes malingii, Hook, 

 p. 66. Hook and Bak., syn. 



Stipes 1-3 in 1., slender, naked ; fronds pendent 4-6 in 1., 

 1-1 J br., linear-oblong, bi-or tri-pinnatifid ; main rachis 

 densely clothed with close tomentum, free throughout; 

 pinnae |-f long, oblong or ovato-rhomboidal, cut down to a 

 rounded rachis ; pinnules deeply flabellately and sub-pinna- 

 tifidly cut ; ultimate segments linear-filiform, 1-3 long ; the 

 substance coriaceous and soft with a dense coating of 

 tomentum, a single vein only in each segment ; sori 2 to 12 

 to a pinnse terminal on the segments ; involucre divided 

 about half-way down ; valves denticulate at the apex, and 

 shaggy like the frond.

 Zealand.
