354 THE JOURNAL OF BOTANY 



Mitten considered his Acrohryum kniosiim a distinct species from 

 A. longissimum ; and this view is entirely borne out by specimens 

 named by him. Mr. H. N. Kidley sent him a number of specimens 

 from the Malay Peninsula, collected in 1896, for determination ; of 

 these five were named by Mitten A. lanosuvi. Two of these I have in 

 my herbarium ; they are two quite ordinary but very discrete forms 

 of Aerobryojjsis loiigissima, one (No. 447) having a somewhat dense 

 and rigid habit, with the leaves comparatively shortly pointed — one 

 of the characters which Fleischer assigns to A. lanosa (Mitt.) ; the 

 other (No. 506) a long flexuose form with the leaves finely 

 attenuated to an almost filamentous point — the reverse of what 

 A. lanosa, as understood by Fleischer, ought to be! It would be 

 quite impossible in the face of these two specimens to maintain 

 that Mitten had in view for his A. lanosum something distinct 

 from A. longisshmim. 



Fleischer's peristome characters (drawn from a Ceylonese or 

 Celebes plant) may of course have specific value, though I should 

 doubt it, but if so a new species must be founded on those 

 characters, without reference to Mitten's A. lanosum. 



New Zealand Mosses. 



In Journ. Bot. 1894, p. 78, H. Boswell gave a Hst of some 

 New Zealand Mosses and Hepaticse determined by him for Mr. 

 Cosmo Melvill. Mr. Melvill has sent me specimens of many of 

 these, and I find that certain corrections must be made. A useful 

 footnote drew attention to the omission from the Handbook of 

 the N.Z. Flora of Camjjylojms holojnitrmm (C. M.) ; but the species 

 is not, as Boswell gives it, G. holomitrion H. f. & W. in Lond. 

 Journ. Bot. 1844. It was there described as C. capillaceus. 

 C. Miiller altered the specific name to holomitrmm owing to the 

 name cajnllacens having been already employed. 



The specimens named Caminjlopus bicolor Hornsch. belong to 

 C. appressifolius Mitt. 



Dicramim rohustum H. f. & W., No. 115, is D. Billardieri 

 Brid. 



Macromitrmm longirostre Schw^aegr. is M. gracile Schwaegr. 



M. recurvifolmm Brid. is ill. loiigipes C. M. 



Atriclmm ayigustaUim Brid. The Australasian plant is distinct 

 from A. angustatum, and should be known as A. ligulatum Mitt. 



Hyp)opterygium discolor Mitt. This is quite inseparable, I 

 think, from II. novcB-seelandice, C. M., whether it be H. discolor or 

 not. Mitten's plant seems to be a dubious one ; he afterwards 

 referred it to H. ScotticB C. M. ; Kindberg retains it as a species 

 allied to H. tamarisci. 



Hypnum Kneiffii Bry. eur. is H. brachiatum Mitt. 



Hypnodendron comaturti (C. M.). The specimen I received is 

 H. comosum (La Bill.) Lindb. 



Hehnsia'^ collina n. gen. and sp. Mr. E. S, Salmon has already 

 pointed out that this is Leptostomimi macrocarpum R. Br. 



* It may be noted here that Boswell's reference to Helms's " lamented 

 death" was inaccurate ; he died at Sydney, July 17th, 191-1.— Ep. Journ. Bot,
