below the apex, which is more or less crenulate; areolae roundish, more opaque than in the preceding. Capsule 

 remarkably small for the size of the plant, subcernuous, pale, on a slender pedicel. Male flowers axillary, scattered 

 here and there along the stem, terminal with the seta in var. 0.— Plate LXXXIII. Fig. 8 :— 1, plant, natural 

 size ; 2, capsule ; 3, leaves ; 4, apex of leaf, magnified.

Somewhat taller and more robust than the last, from which it is readily distinguished when dry by the distant 

 involute crisped foliage.— Leaves more obtuse and more truly ligulate, the dorsal wing ceasing considerably above 

 the base. Seta strong, flexuose, rather short. Male flower terminal on separate stems, growing often apart from 

 the fertile plant.— Plate LXXXIV. Pig. 1 :-l, plant, natural size; 2, capsule; 3, part of peristome; 4 and 5,

11. Fissidens dealbatus, Hook. fil. et Wils.j dioicum, tenellum, foliis 3-jugis oblongis acuminatis 

 lamina apicali folium excedente anguste marginatis enervibus cellulis magnis hyalinis rhomboideis, capsula 

 suberecta ampullacea sub ore constricta, operculo rostrato capsula longiore. (Tab. LXXXIV. Fig. 2.)

Somewhat larger than the allied American species F. hyalinm, Hook, et Wils., and distinguished by the 

 bordered leaves, larger areote, and longer operculum.— Peristome longer, the teeth when dried paired. Annulus 

 none. Calijptra reddish-brown, conico-subulate.— It differs from F. retieulosus, Schimp., in the complete absence 

 of a nerve.— Plate LXXXIV. Fig. 2:— 1, plants, natural size; 2, a plant, magnified; 3, immature capsule; 4, 

 calyptra; 5, mature capsule; 6, immature, and 7, mature opercula; 8, leaf:— all magnified.

Peristomium simplex. Denies 16, bifidi, ut in Fissidente, sed linea media nulla, plerumque truncati, 

 irregulares. Calyptra conica, basi subintegra. Capsula minuta, brevi-pedicellata, erecta, asqualis, pediceUo 

 sensim in capsulam dilatato, collumque spurium sistente.— Folia Fissidentis remote, lamina dorsali longiore. 

 Plantse fluilantes, tenera, filiformes, ramosce. 



1. Conomitrium Dillenii, Montagne; caule frondiformi fluitante ramoso, foliis alternis distichis 

 oblongo-lanceolatis subscalpclliformibus erectis evanidinerviis, pedunculis solitariis (rarius gemellis) axilla- 

 ribus cauligenis, capsula ovata, operculo cuspidato incurvo. '—Montagne in Ann. des So. Nat. 1837, et

Hab. Northern Island : East Coast, in watercourses, Colenso. 



In our specimens the male and female flowers are contiguous, and the teeth of the peristome regular. 



Tribe IV. Dicrane/e. 

 Gen. IX. DICNEMON, Sehwmgr. 

 Peristomium simplex. Denies 16, ultra medium bipartiti, cruribus nodosis incurvis. Calyptra 

 magna, cucullata. Capsula elongata, insequalis, periehsetio elongato vaginante fere immersa.— Caulis rep- 

 tans, surculis erectis ramosis. Habitus sciuroideus Leucodontis. Vita arborea, perennis.
