AUSTRALIAN AND SOUTH SEA ISLAND STICTACE^ 265 



In addition to the above we have two other rather marked forms 

 from Allumbah, Queensland, collected by Mr. B. Waller. One has 

 the minute lobules of the var. myrioloba, but is more costate at the 

 base, and approaches in this respect the type from New Zealand. 

 The other form is less costate at the back of the thallus, but is 

 densely clothed with branched rhizins. 



5. lacera, MuU-Arg. 



New Zealand : — There are several collections of this species 

 in the Kew collection, collected by Colenso, Logan, 

 Sinclair, and Knight. It is a very small species, and 

 was considered by Dr. Nylander as a variety of 5. filix. 



S. Sayeri, Miill-Arg. 



Queensland : Bellenden-Ker (Sayer, No. 584) ; Allumbah 

 (Waller). 



Seems to me very close, if not identical, with the next species. 



S. pedimculata, Krplhbr, in Journ. Museum. Godeffroy, Bd. 

 1, Heft 4 (1874), p. 97, Taf. XIV., fig. 2-4 and 8, and 

 in Rechinger's " Botanische und Zoologische Ergebnisse 

 einer VVissenschaftlichen Forschungreise nach den 

 Samoa-Inseln, dem Xeuguinea-Archipel und den 

 Salomonsinseln," p. 69 (265), Taf. ii, fig 3 (1907). 



Specimens of this are in Herb. Kew from Fiji, collected by J. 

 Home in 1877-78. 



Rechinger I.e. cites S. Shirleyana, Miill-Arg., as a synonym. 

 For further remarks on this see S. stipitata. 



S. latifrons, A. Rich. 



New Zealand : Several specimens of this are in Herb. Kew, 

 collected by Lyall, Hooker, Stephenson and Knight. 



In addition to the above, we have in the Wilson collection a 

 small scrap collected by Mrs. Martin, and a fine specimen in the 

 collection of the Linnean Society of N.S. Wales. In the National 

 Herbarium of New South Wales there are some fine specimens 

 from Back River, Tasmania, collected by Gunn and Oldfield. 



S. latifrons var. Menziesii, Bab. 



New Zealand : Dusky Bay (Menzies), Middle and Southern 

 Island (Bidwill), (Lyall) ; Auckland (Drury), Otago 

 (Hector), Napier (Colenso), Dunedin (Lindsay), Grey- 

 mouth (Helms), Ohakune (Cheel), Waiwera and Pokeno 

 (Flockton). 



Both the species and variety are very variable in structure, 

 lobation and colour. In some intermediate forms it is difficult to 

 distinguish the species from the variety, although the extreme forms, 

 look very different.
