Gen. LYII. HYMENODGN, Ilook.fil. et Wils. 



Peristomivm simplex. Denies 16, membranacei, sequidistantes, lineari-subulati, planiuseuli, fugaces, 

 apicibus cohasrentes, membrana basilari angusta connexi. Calyptra dimidiata. Capsula suberecta. Oper- 

 culum rostratum. Morescentia dioica. — Folia distiche imhricata, elliptica, plana, pilifera, papillosa, areolis 

 subrotundis, minutis. Habitus BMzogonii. Yita arborea, prasertim ad truncos Filicum arbor escentiurn. 



According to C. Miiller (Bot. Zeit. Nov. 1847), the peristome is internal, but its origin from the sporular sac 

 seems to us to be very questionable. Better specimens are wanted for further examination.

 bncatis patentibus elliptico-oblongis planis longe piliferis evanidinerviis papillosis margine crenulatis peri- 

 chsetialibus lanceolato-acuminatis erectis, seta elongata basilari gracili, capsula inclinata ovali ore coarctata.

Hab. Northern Island : Bay of Islands, Sinclair, Colenso ; common on the trunks of Oyathea deal- 

 bata, but not observed elsewhere, J. B. II. 



Also found in Tasmania.— Surculi | inch long. Leaves light verdigris or subglaucous green, not at all glossy, 

 moistened in water with difficulty • the piliform apex nearly as long as the rest of the leaf; nerve vanishing below it ; 

 reticulation almost granular, brittle; the areola? roundish, prominent and papillose on both sides. Seta nearly 1 inch 

 long, reddish. Capsule slightly contracted at the mouth. ■ Teeth of the peristome long, white, fugacious, longitudi- 

 nally striated, and transversely but faintly articulate. Young calyptra white, small. — The Brazilian E. ceruginosus 

 has narrower leaves and the nerve excurrent. II sericeus, C. Miiller, from Java, is described with glossy leaves and 

 excurrent nerve. — Plate XCII. Fig. 3 ; — 1, plant, natural size; 2, capsule; 3, part of peristome; 4, calyptra; 5, 

 portion of stem ; 6, 7, leaves : — all but fig. 1 magnified. 



. Tribe XXII. Hypopteiiygiejs. 

 Gen. LVIII. HYPOPTEBYGIUM, Bridel. 



Peristomium Hypni. Calyptra conico-subulata, plerumque latere fissa. Capsula sequalis, longe pe- 

 dunculata, cernua vel pendula. Operculum e basi convexa rostratum. — Caulis repens. Surculi dendroidei, 

 pinnatim ramosi, complanati. Folia tristicha, lateralia pterygoidea, obliqua, verlicalia, dorsalia (tegmina 

 dicta) minora aliterque conformata, subappressa. 



The fructification in this and in the two following genera is lateral, underneath the proper leaves, not (as Bridel 

 supposed) in the axillae of the accessory or dorsal leaves.
