cernua, oblonga, insequalis. Operculum longirostre, rostro obliquo. Calyptra cucullata.— Folia Umbo e cellu- 

 larum strato unico conflato, nervata. Caules erecti {non repentes), perennes, caspitosi. 



1. Dicranum Tasmanicum, Hook, fil.; dioicum, caule elongato erecto, foliis laxiusculis patentibus 

 lanceolato-oblongis obtusis canaliculatis integerrimis apice concavis evanidinerviis siccitate incurvis crispulis, 

 capsula erecta tarbinata macrostoma, operculo longirostri. — Hook. Io. Plant, t. 248. 



Var. 2 ; foliis laxioribus latioribus, apice cymbiformibus. 



Var. 3 ; foliis angustatis subulatis crassinerviis (apice recto) baud concavis.

 Coast, wet cliffs, etc., Colenso. 



Closely allied to D. virens, D. pellucidum, and D. squamosum, growing like the two latter in wet places, and 

 subject to considerable variation.— Learns very concave at the apex, which is sometimes slightly reflexed ; colour 

 variable from pale green to lurid, often reddish-brown, as in the original specimen from Tasmania. Teeth frequently 

 trifid, but by no means constantly so (as occurs in D. cerviculatum and in other species), large, erect, or spreading 

 when dry. Male flowers on separate plants. Stem 1 inch long or more. Capsule of firm texture, on a stout pedicel, 

 i inch long. Operculum, with a slender inclined beak larger than the capsule, annulus absent.— Var. 3 is a curious 

 form, probably growing near running water, and may be compared with an analogous form of Hypnum hispidum. 



2. Dicranum vaginatum, Hook.; caule elongato ramoso gracili, foliis remote imbricatis e basi lata 

 quadrata vaginante lineari-subulatis rigidis crassinerviis subintegris, capsula ovata erectiuscula, operculo 

 Longirostri,— Hook. Muse. Exot. t. 141, non Fl. Antarct. 



Var. /3. clathralum; foliis luridis, peristomii dentibus perforatis subtrifidis, capsula turbinata.

 Our specimens agree well with the original in all essential points.— Leaves distant, scarcely altered when dry 

 suddenly narrowed from the broad sheathing base into a long, subulate-setaceous, widely patent prolongation, the 

 squarrose portion of the leaf consisting of the thick predominant nerve, which is slightly toothed at the apex. Teeth 

 of the peristome longer than in allied species, rough with prominent papilla,, variously perforated, the articulations 

 distant and often connecting the divisions. Annulus none. Capsule more or less erect, ovate or turbinate. Stems 

 1-2 inches long, slender. Inflorescence dioicous.— Found also in the Andes of Columbia and Colchagua. 



D. vaginatum of Fl. Antarct. p. 407, from Hermite Island, proves different, having leaves gradually tapering 

 from the dilated base, channelled above; apex acute, entire; nerve not predominant. 



3. Dicranum campy lophylkim, Tayl. ? "caule csespitoso, surculis subsimplicibus erectis, foliis sub- 

 distantibus, ex oblonga arete vaginante basi elongate subulatis integerrimis, nervo tenui percursis, apice 

 flexuoso incurvis; capsula ovata, erecta, subasquali; operculo rostrato."— Lond. Joum. Bot. v. 7. p. 281. 

 Hab. Northern Island, Colenso. 



Of this Moss little can be determined, belonging as it does to an intricate series of forms closely allied to D. 

 Schreberi. The description agrees with some examples from the Andes of Quito, in Dr. Jameson's collection, whence 

 D. campylophyllum and D. Jamesoni, Taylor, were derived. D. Gayanum, Montague, is another form of the series, 

 resembling D.filiforme (vuleanicum, Bridel), and to these must be added B. Guilleminianum, and B. aulacocarpum, 

 Mont. Our Moss has leaves longer, more rigid than Z>. Schreberi, less suddenly dilated below, with a stronger 

 nerve, and the capsule, though more or less oblique, is without any appearance of struma. Operculum longer 

 Inflorescence dioicous. 



4. Dicranum Schreberi, Hedw.; caule breviusculo subsimplici, foliis e basi dilatata vaginante lan- 

 ceolato-subulatis patentibus siccitate flexuosis canaliculatis subintegris nervo debili percursis, capsula ovato 

 oblonga cernua, operculo brevirostri capsula; subtequali. — Hedw. Spec. Muse. t. 33. Bridel Br. Vn
