Grimmia Ibuchanani, Stirton. 



" Stems loosely tufted ; leaves oblong amplexicaul, plane 

 margined, laxly areolated, terminating abruptly in very long, 

 green, nearly entire subulae, which are composed almost 

 entirely of the prolonged nerves; perichsetial leaves longer 

 and narrower at the sheathing bases, otherwise identical ; 

 fruitstalk curved ; capsule ovate, regular, furrowed when dry, 

 pale ; lid conico-rostrate, oblique, more than half the length 

 of the capsule ; calyptra dimidiate, covering half the capsule ; 

 teeth deep-red at base, curved, bifid into long pale subulate 

 points ; inflorescence in all likelihood dioicous ; antheridia not 

 detected." — Dr. J. Stirton, in Pro. Nat. Hist. Soc. Glasgow, 

 vol.ii. (1876),p. 187. 



Dr. Stirton sent me this moss with the remark, " Dr. 

 K. Mliller refers Grimviia buchanani to another genus." I at 

 once recognised it as Dicranodontium flexipes, Mitt., and Dr. 

 Brotherus has confirmed my identification. Dr. Stirton does 

 not possess specimens of the other mosses described below. 



Since the above was written I have received from Dr. Karl 

 Mliller a copy of his Symbolae ad Bryologiam Australis (Hed- 

 wigia, xxxvii., 1898), in which (p. 116) he describes this moss. 

 He considers it a new species, and publishes it under tlie 

 name Angstrdmia [Campy lopodi^an) buchanani. He adds, 

 "In Hb. Stirton sub nomine Grimmia buchanani ejusdem 

 fuit. Camiiylopodium capillaceum (H. f. et W. sub Dicrano) 

 insulae septentrionalis caule dicranoideo fere pollicari uncinato 

 primo visu distinguiter." 



Tortula incurvidens, Stirton. 



" Stems gregarious, short ; leaves lanceolate, with plane 

 entire margins, crisped when dry, texture dense, opaque 

 above, pellucid and quadrangular at base, nerve strong, in- 

 distinct near the apex, which is somewhat cucullate ; capsule 

 red, erect, on a thick red seta; peristome arising from a basi- 

 lar membrane, broad and prominent above the mouth of the 

 capsule, irregular, rough with minute papillae, and crossed 

 by two or three septa, incurved when dry, converging into a 

 cone W'hen moistened ; lid obliquely rostrate, subulate, nearly 

 as long as the capsule ; calyptra dimidiate, extending more 

 than half-way down. 



" Approaches in several of its characters to Tortula 

 ambigua, but diverges in others." — Stirton, op. cit., p. 187. 



Bryum contortum, Stirton. 



" Dioicous, densely caespitose ; stem radiculose ; lower 

 leaves small, scattered, upper suddenly enlarged, closely im- 

 bricated in a moist state, contorted when dry, ovate-oblong, 

 terminating in long smooth reflexed points formed by the
