118 ELOKA OF NEW ZEALAND. [Musci. 



Operculum nearly as long as the capsule. Peristome yellow, the inner one furnished with cilia. Calyptra dimidiate, 

 not mitriform. 



2. Hypopterygium rotulatum, Hedw. ; monoicum, surculo bipinnatim ramoso inferne nudo, ramis 

 horizontaliter radiatis, foliis distiche imbricatis patentibus rotundo-ovatis subflaccidis (siccitate cnspuhs un- 

 dulatis) marginatis evanidinerviis apice subdenticulatis, tegminibus subrotundis acuminulatis brevissime 

 nervatis, capsula pendula, operculo rostrato. — Leskea rotulata, Hedw. Sp. Muse. t. 51. Bridel, Bryol. Univ. 

 pt. 2. p. 713? 



Hab. Northern Island : Auckland, Sinclair. Southern Island, Li/all. 



Also found in the Mauritius. In the absence of authentic specimens, it is almost impossible to ascertain 

 whether this or the following species be the one intended by Hedwig. The figure of Leskea rotulata does not well 

 exhibit the ramification, but we refer this Moss to that species because it is the only one in which the accessory 

 leaves can be considered nerveless. — Surculus | inch long, or more. Leaves dull green, not crowded, more loosely 

 reticulated than in the following, much undulated and crisped when dry; nerve ceasing halfway up the leaf. 

 Perichatial leaves ovate-lanceolate, acuminate, concave. Inner peristome with cilia. — II. laricinum, Hook., differs m 

 the larger size and leaves not bordered. 



3. Hypopterygium SmitManum, Hook. fil. et Wils. ; dioicum, surculo bipinnatim ramoso inferne nudo, 

 foliis distichis ovato-subrotundis acuminulatis concaviusculis deflexis marginatis evanidinerviis apice denti- 

 culatis, tegminibus subrotundis acuminulatis solidinerviis, perichsetialibus lanceolato-acummatis, capsula pen- 

 dula, operculo rostrato. — Hookeria rotulata, Smith, in Linn. Trans, v. 9. p. 279 (non Hedw. Sp. Muse).

A Tasmanian Moss, essentially distinguished from the preceding by the dioicous inflorescence, and by the con- 

 tinuous nerve of the accessory leaves. — Leaves more obtuse and concave, of firmer texture, more evidently margined, 

 more or less deflexed, bending over the accessory leaves, pale yellowish-green (but a dull green variety of this with 

 softer leaves, crisped when dry, is found in Norfolk Island, and may be mistaken for the true II. rotulatum).— Seta 

 and capsule pale reddish. Calyptra dimidiate. Inner peristome with cilia. — Very probably this species has been 

 confounded with the preceding by Bridel and others. 



4. Hypopterygium setigerum, P. Beauv. ; dioicum, surculo bipinnatim ramoso inferne nudo, ramis ra- 

 diatis horizontalibus, foliis ovatis acuminulatis spinuloso-serratis evanidinerviis, tegminibus ovatis longius 

 acuminatis spinoso-ciliatis, setulis intrafoliaceis aciculiformibus tegminibus longioribus, capsula pendula 

 brevipedunculata basi tuberculata, operculo longirostri. — Hypnum setigerum, P. Beauv. Prodr. JEtheog. p. 

 70. Leskea tamariscina, Hedw. Sp. Muse. I. 51 (non Swartz). 



Hab. Common throughout the Islands, Cunningham, etc. 



A native of Lord Auckland's Group. — Surculus nearly 2 inches high. Frond roundish, horizontal, 1 inch or 

 more in diameter. Leaves yellowish-green, rather glossy, not much altered by drying, sharply serrulate. Seta very 

 thick, i inch long, purplish, suddenly bent, not arcuate at the top ; capsule pendulous, closely applied to the seta, 

 ovate, pale brown, very abrupt and tuberculate at the base. Operculum as long as the capsule, pale yellow. An- 

 nulus distinct. Calyptra conico-mitriform, not dimidiate, coriaceous, as long as the operculum, yellowish. 



An authentic specimen of Leskea tamariscina, Swartz, in the Hookerian Herbarium, from Dr. Swartz, is iden- 

 tical with Hypnum laricinum, Hook. Muse. Exot. ; and Hedwig greatly erred in uniting this to it. //. setigerum is
