FLORA OF NEW ZEALAND. 



\Mu8Ct. 



minutis ovato-lanceolatis, seta breviuscula, capsula parva cemua vel erecta ovata, operculo rostellato, 

 calyptra basi fimbriata— Hypnum microcarpon, Eedwig, Sp. Muse. t. 59. Pterygophyliura microcarpon, 

 Bridel) Bryol. Univ. v. 2. p. 342. 



Hab. Throughout the Islands, Cunningham, Logan, Lyall, etc. 



A Tasrnanian Moss.— Stem 1-3 inches long. Leaves larger than in any of the preceding, pale green, whitish 

 in the middle, appressed and complanate when dry, sometimes bending backwards ; areola; of the central portion near 

 the nerve large and pellucid, thence gradually diminishing in size as they approach the margin, where they are 

 extremely small. Seta about J inch long, the vaginula visible from the small size of the perichsetial leaves. Capsule 

 small, purplish, cernuous in some of the specimens, in others erect, as figured by Hedwig, like that of Daltonia, with 

 which it agrees in the fringed calyptra (the fringe not always present in the specimens). The cellules forming the 

 wall of the capsule are curiously marked with radiating strise. Teeth of the peristome with distant dorsal ridges. 

 . rather short. 



§ 3. Pterygopiiylltjm, Bridel. — Calyptra basi Mud fimbriata, plus minus laciniala. Peristoma extend dentes 

 remote lirati. Folia complanata, immarginata, laxe areolata, oblusa, nervo subbifurco, medio evanido. 



9. Hookeria quadrifaria, Smith; dioica, caule erecto subramoso, ramis complanatis, foliis distiche 

 imbneatis lateralibus verticalibus rhomboideo-obovatis obliquatis obtusis intermediis erecto-appressis subro- 

 tundis omnibus crebre ac rninutissime denticulatis evanidinerviis, capsula oblonga pendula, calyptra brevi 

 pilosiuscula. — Eooh. Muse. Exot. t. 109. Scliwagr. Suppl. i. 162. Pterygophyllum, Bridel. 



Hab. Throughout the Islands ; in dark damp woods, not uncommon. 



The largest species of the group. — Barren stems 3 to 10 inches long, and with the foliage \ inch broad. 

 Fertile specimens 1 inch long. Leaves large, pale green, little altered by drying, whitish when old, rounded and 

 obtuse at the apex ; texture thick, composed of large, coarse, hexagonal cells ; margin of leaf minutely denticulate in 

 the original fertile specimen of Mcnzies and in ours, but the two barren specimens of Menzies from Dusky Bay have 

 the margin entire. Nerve thick at the base, forked above. Perichatial leaves small, ovate. Seta 1 inch long. Teeth 

 of peristome beautifully variegated, having two prominent, cylindrical, red, dorsal ridges, widely separated, and the 

 internal part of the tooth being yellow. Calyptra subcorneal, small, with a few scattered hairs.— The disposition of 

 the leaves is certainly not quadrifarious, but §-, or two rows of intermediate leaves on the upper side, two at the 

 back, and two rows of vertical-lateral leaves on each side. 



10. Hookeria rohusta, Hook. fil. et Wils.; dioica, caule rigido elongato subramoso, foliis distiche im- 

 bneatis lateralibus patentibus verticalibus ovato-oblongis obtusis dentatis evanidinerviis intermediis erectis 

 appressis obovatis siccitate undulatis, capsula ovata pendula, calyptra glabra. (Tab. XCIII. Fig. 5.) 



Hab. Northern Island, Colenso. 



Nearly as large as the preceding, which it so much resembles as to be easily mistaken for it. — Stems 1 to 4 

 inches long. Leaves narrower, less crowded, of thicker substance, pale yellowish-green, inclining to glaucous, slightly 

 undulated when dry; nerve purplish. Seta ■§ inch long. Teeth smaller than in the last, the dorsal ridges more ap- 

 proximate. Calyptra subcorneal. — This and the next species may perhaps be states of II. dentala, Hook. fil. et Wils. 

 (in Fl. Antarct. pt. 1. t. 62. f. 2); but after careful comparison, it seems advisable to separate them as species.

11. Hookeria nigella, Hook. fil. et Wils. ; dioica, caule humili erecto-incurvo rigidulo subramoso, 

 foliis remotiusculis complanatis lateralibus spathulatis basi angustatis dentatis seminerviis intermediis obo- 

 vatis dentatis pericheetialibus rotundo-ovatis concavis, capsula subrotundo-ovata pendula, calyptra nuda. 

 (Tab. XCIII. Tig. 6.) 



Hab. Throughout the Islands : common in woods.
