    Elateres tenues dispiri, oniiies decidui, alii autem in capsulte fundo lougius persistentes. Sporce majuscuhe muriculatae. Andrcecia in spica brcvi tcrminali; bracteae paucijugse foliis subconformes diandrse. Hab. Iu regionibus montosis ad saxa umbrosa arboresque. Distr. Per orbem terrarum disperse, nullibi copiosoe, in Andibus autem sylvaticis, alt. 1200—3500ra, sat frequentes et ex arborum truncis ramisque csespitibus magnis dependentes, ad saxa rariores; in planitie fluminis Amazonum nullibi visas fuerunt. E speciebus paucis hodie cognitis 4, 2 novas, legi. Herherta, e foliis praslongis, dicrauis, decurvo-secundis, a casteris fere omnibus hepaticis distat, et Hypnum uncinatum, H. commu- tatum, &c., vel Dicrannm scopcirium primo visu valde refert. Obs. In Herherta acanthelia and some other species of which I have been able to examine ripe fruit, the innermost membrane of the capsule is con- tinued over the apex of the pedicel, where it consists of lineari-fusiform, usually pointed cells, lined with semiannular fibre or sometimes with an unbroken spiral. I saw one case of a cell containing a double spiral. It was easily distinguished from the elaters by its much greater width, and the stouter laxer helix; besides by its being laterally connected with other similar cells into a continuous membrane. A few of the basal leaf- cells of some of the species are also lined by a spiral fibre, as was first poined out by Gottsclie for H. juniperina. A good many elaters remain attached to the base of the capsule for a short time after it bursts, but arc soon liberated ; they are of the ordinary size and structure. A. Folia 4plo fere longiora quam lata. 1. H. pensilis. Albido-viridis subsimplex, nisi pro innovatione sub- florali subindeque stolone uno alterove basali.
