ELOBA 01? NEW ZEALAND. 



[Musci. 



Pound in Tasmania and Java.— From 1 to 3 inches in height or more. Seta f inch to 1| inch, straight in the 

 larger specimens, often arcuate in the smaller ones. Leaves glossy, bright green, the intermediate ones smaller, ap- 

 pressed. Capsule sometimes curved.— Eypnum Reinwardtii, Hornschuch, from Java, differs in the narrower, more 

 tapering, uniform leaves, longer seta, and longer operculum. The arrangement of the leaves in I. spininervium is 

 analogous to that of Racopilum. 



7. Isothecium marginatum, Hook. fil. et Wils. ; dioicum, comosum, ramis subverticillatis pinnatim 

 ramulosis vel simplicibus, foliis ovato-oblongis vel ovato-lanceolatis concaviusculis marginatis serrulatis dorso 

 spinulosis solidinerviis, capsula subcylindrica curvata sulcata cernua, operculo rostrato. (Tab. LXXXIX. 

 Fig. 2.) 



Hab. Northern and Middle Islands ; common in watery places. 



Taller and less elegant than the last, with dull green foliage, shrinking and twisting when dry. Essentially 

 distinguished by the margined, narrower leaves.— Plate LXXXIX. Fig. 2 :— 1, plant, natural size; 2, portion of 

 stem and leaves ; 3, leaf : — both magnified, 



8. Isothecium comosum, Labillard.; dioicum, comosum, ramis subverticillatis pinnatim ramulosis, 

 foliis patentibus subsecundis ex ovata basi subulato-setaceis rigidis serratis excurrentinerviis, capsula subcy- 

 lindrica sulcata pendula, operculo longirostri. — Labill. PI, Nov. Roll. Schwcegr. Suppl. t. 91. 



Var. /3 ; foliis minoribus brevioribus minus serratis, nervo minus excurrente, seta breviore. 



Hab. Northern and Middle Islands : Waikehi, Sinclair. Dusky Bay, In/all, and in several interme- 

 diate localities. Yar. j3. Dusky Bay, Menzies. 



A Tasmanian, Australian, and Javanese Moss. — Variable in size, 1-6 inches long, and in aspect ; sometimes 

 with several successive innovations and the whorls of branches crowded, in other cases with a single whorl or 

 roundish horizontal frond at the summit of astern densely covered with brown radicles. Leaves rigid, the stout nerve 

 projecting as a rough bristly point of greater or less length. Seta f-2 inches long, often numerous, aggregate 

 from the centre of the frond. Operculum nearly as long as the capsule. — Approaches to some Bartramia in aspect. 

 Hypnum divaricatum, Hornschuch, from Java, is nearly allied, but has shorter and wider leaves, nerve not excurrent. 



9. Isothecium gracile, Hook. fil. et Wils. ; dioicum, caule ramoso, ramis gracilibus recurvis, foliis 

 erecto-patentibus secundis ellipticis concavis obtusiusculis subdenticulatis enerviis, perichsetialibus squar- 

 rosis acuminatis, seta longiuscula lsevi, capsula ovata cernua, operculo conico. — Fl. Antarcl.pt. 1. p. 29. 

 t. 61./. 3. 



Hab. Middle Island: Otago, Mr. John Buchanan {Hb. Gourlie). 



Also found in Lord Auckland's Islands. Until fertile specimens were obtained, it was difficult to distinguish 

 this Moss from Pterogonium filiforme ; from which, in the structure of the peristome and cernuous capsule, it is 

 essentially different. — Annulus large. Seta red, nearly 1 inch long. — Allied to /. pulvinatum. 



Tribe XIX. Htpnace^e. 



Gen. LIV. HYPNUM, Linn. 



Peristomium duplex: exterius, dentes 16, lanceolati, reflexiles, intus trabeculati, linea media notati.; 

 interims, membrana carinato-sulcata in processus 16 carinatos ciliis interpositis mediotenus fissa. Calyptra 

 cuculliformis, glabra. Capsula insequalis, arcuata, cernua, plerumque annulata, longe pedicellata. Habitus 

 varius. Caulis plerumque repens, vage vel pinnatim ramosus. 



In this genus we retain all but the dendroid species with curved cernuous capsules, and the RMzogonia of 

 Bridel, with fructification at the rooting base of erect surculi.
