382 SOME ORYPTOGAMIC NOTES, 



Prod., 333, 1827. Assuming this identity, the name H. peltahhm 

 must stand. Poiret published his species, in 1808, as Tricho- 

 manes peltatum. In 1810, Willdenow published it as Hymeno 

 phyllum unilaterale (certainly the most appropriate name): and 

 in 1830-31, it was, as already stated, described and figured as 

 H. Wilsoni Hook., (specimens collected in Ireland by Mr. Wilson). 

 It is interesting to know that we have this fern, as well as H. 

 tnnbridyense, in Australia. I have no hesitancy in separating 

 the two species, even on the ground of the unilateral pinna? of 

 H. peltatum, to say nothing of its differently-shaped and entire 

 indusium. 



There are specimens in the Herbarium (Sydney) collected on the 

 Snowy River by Mr. W. Bauerlen, as also specimens from Tas- 

 mania (Archer &, Gunn), but these have, until now, been placed 

 in the H. tunbridgense box. Mr. Boorman's specimens are 

 ample, quite characteristic, and in good condition. 



2. Hymenophyllum rarum R.Br. 

 This southern species was collected on Mt. Wilson by Mr. 

 Boorman and myself, in May, 1915. Not previously recorded 

 north of Illawarra, though Mr. Whitelegge reports having found 

 it in Blackheath Glen. 



3. Dryopteris acuminata (Lowe) Watts; Lastrcea Moore. 



A small, dark green, shiny Dryopteris, found here and there 

 in New South Wales, has hitherto been identified, for the most 

 part, with D. decomposifa (R.Br.), from all forms of wiiich it 

 certainly differs. Mr. Thos. Whitelegge, for many years, has 

 regarded it as luovfe^a Aspidium acuminatum (¥'\\., vi., t.ll, 1857). 

 Lowe's description is scarcely adequate, but his accompanying 

 figure leaves little or no doubt in my mind that Mr. Whitelegge's 

 view is correct. Lowe's species (supposed by him, apparently, 

 to have been Willdenow's A. acum.inatum, which is, according to 

 Christensen, a syn. of Nephrolepis biserrata) was based on speci- 

 mens grown at Kew, but he did not know to what country it 

 belonged. Many years ago, Mr. Whitelegge sent specimens of 

 our Australian fern to Mr. T. Rogers, of Manchester, who con- 

 firmed its identification with Lowe's species. Hooker and Baker
