ELOKA OP NEW ZEALAND.

Of tins a few fragmentary specimens are present. The species is known by the very slender, setiform, fragile 

 leaves, whose nerve is predominant in the upper half, occupying the whole width of that part. It is a native of 

 Lord Auckland's Group and Campbell's Island. 



10. Dicranum Menziesii, Tayl. ; caule dense radieuloso-tomentoso, foliis confertis secundis subrigidis 

 basi lanceolatis serrulatis siccitate strictis crassinerviis, seta brevi, capsula oblonga suberecta substrumosa 

 subexserta, operculo longirostri. — Tayl. in Phytologist, 2. p. 1094. Fl. Anlarct. p. 128. t. 58./. 4. 



Var. /3. rigiclum ; foliis rigidioribus minus confertis nigro-viridibas patulis subfalcatis, caule robnstiore. 



Hab. Throughout the Islands, common : Dusky Bay, Menzies. 



Stem densely tomentose, with whitish, fibrous radicles, producing male nidulant flowers. Leaves yellowish-green, 

 silky, crowded, setaceous ; nerve thick and strong, prominent, very conspicuous in a dry state, by which the species 

 is readily distinguished from 1). setosum and its allies. Found also in Lord Auckland's Group. 



11. Dicranum Sieberianum, Hornsch. ; caule ramoso fastigiato, foliis falcatis convoluto-canaliculatis 

 ovato-lanceolatis acuminatis superioribus piliferis tenuissime pellucido-marginatis dorso papillosis calycinis 

 vaginatis piliferis, capsula longe pedunculata ovali cernua parva, operculo longirostri.— Schwcegr. Suppl. 

 t. 252. Leucodon pallidus, Hook. Muse, JExot. 



Var. /3j foliis siccitate appressis vix undulatis dorso subleevibus. 



Hab. Northern Islands : Bay of Islands, Cunningham. Var. /3, in muddy places on rocks, /. I). II. 



Colour yellowish. The var. /3. not unlike a Bartramia.— Leaves entire, not serrated as described by SchwEeg- 

 richen. 



Gen. XII. DICRANODONTIUM, Bryol. Mtrqp. 



Peristommm simplex. Denies 16, lineari-lanceolati, remotius articulati, infra medium vel ad basin usque 

 bifidij crura insequalia, subulata. Capsula in pedicello arcuato demissa, sequalis, vix striata. Operculum 

 oblique subulatum, annulo angusto persistente. Calyptra cucullata, Levis, haud basi fimbriata.— Habitus 

 Bicranoideus. Folia basi vaginantia, dilalata; nemo lato dorso Icevi preedominante. 



This group partakes much of the habit and character of Campylopus, differing in the absence of fringe to the 

 calyptra, and in the want of lamelliform ridges on the nerve at the back of the leaf. 



1. Dicranodontium proscriptum, Hornsch.; caule gracili simplici, foliis secundis remotiusculis e basi 

 dilatata vagmante capillaceis rigidis crassinerviis integerrimis, seta arcuata, capsula elliptica siccitate sub- 

 striata, operculo rostrato.— Cynodon proscriptus, Hornsch. in Ilor. Ber. Didymodon proscriptus, Bridel, 

 Bryol. Univ. Dicranum rostratum, Arnott in Herb. Hook. Campylopus capillaceus, Hook. fil. el Wils. in 

 Bond. Journ. Bol. 



Var. /3 ; elatior, folds distantibus squarroso-patulis flexuosis basi vaginante subrotundis magis dilatatis 

 vaginantibus, nervo solido excurrcnte semitereti, capsula insequali substrumosa siccitate striata. 



Var. 7 ; caule humili, foliis confertis falcato-secundis, capsula ut in var. /3. — Dicranum flexifolium, 

 Schwcegr. Suppl. I. 185 ? (non Hook. Muse. Exot.) 



Hab. Northern Island : Bay of Islands, /. I). II. 



This Moss, abundant in St. Helena, is very variable, and it is only after attentive examination that the above 

 varieties, different as they are in aspect, are here treated as forms of one species. They agree especially in the teeth 

 being marked with fine longitudinal strise, as in Trematodon. — Anmdus large and distinct. Capsule faintly striated 

 when dry. Seta curved when moist, straight when dry. Calyptra quite destitute of fringe. Inflorescence dioicous 

 Campylopus humilis, Mont. (Cent. 5. 39), from Brazil, must be different from the above, which seems to occur also 

 on the Neilgherrie Mountains in the Peninsula of India.
