    turgida ct pro more angulata ; ore vel consfcricto, vel ab initio lato, hiante, integerrimo vel denticulato, ciliato, &c., persaepe lobulato. [In plurimis generibus perianthii anguli primarii ad carinam mediam anthopkyllorum respondent (Hypogonianthew); in aliis sutura marginali anthophylJorum constant (Ejrigonianthecv). In Epigoniantheis solis invenimus frequenter perianthia ad angnlos alata.] In paucis Jungermanieis perianthia omnino deficientia, in aliis vel cum involucro colligatum. et confusum, vel incomplete evolutum, anthophylla 2 vel 3'parva sublibera sistens. Alia pauca genera (.Marsupiocarpece) involucrum cum perianthio in sacculum carnosum pensilem concretum kabent. Calyptra in plerisque obovata vel pyriformis, in aliis longa et angusta, in aliis globosa mvenitur; nunc substantia pertenui nunc carnosa; aut perfecte libera aut (in paucis generibus) cum perianthio, vel cum recepta- culo, vel cum utroque, plus minus alte connata. Pedicellus ut- plurimum sat longus, ad maturitatem ultra perianthium alte exsertus, interdum brevis ; apice vix vel parum diiatatus, nunquam autem (ad Jubulearum instar) in apophysin tarn latam et altam diiatatus ut capsula globosa solum ad longitudinis fissa adpareat; cellulis alternis conflatus, in astate flaceidus vel collapsus, neque (ac in Lejeunea) ad speciem articulatus. Capsula longitudine varia, sphaerica, ovalis, vel subcylindrica, bi-piuristrata, rarissime pro majore parte solum unistrata, cellulis strati intimi frequenter fibris semiannularibus fulcitis ; ad basin usque 4-valvis, valvulae integrae, rarius fissae, rarissime irregulariter ruptae, suturis autem basin versus aliquando inter se incomplete solutis; in plurimis generibus recta3, in perpaucis spiraliter tortse. Elateres valde numerosi, tota facie capsuke interna primum insidentes, capsula dekiscente omnes decidui; vel pauci apicales basalesve, casteris conformes vel diversi, paulo longius* persistentes; angusti, utroque fine tenuiores, tortiles, plerumque dispiri, interdum 3-4-spiri, casu rarissimo alii niono- spiri. Sporce numerosissimae, utplurimum praeminutae, in paucis sat magnae, semper fere globosae, lagves vel scaberulae. The Jubulrn seem to me equivalent to nearly all the rest of the sub- order Jungermanictcecc. The structure of the capsule, and especially of the elaters, is unique among hepaticae. So great is their abundance and variety in aequatorial forests, that they constitute fully half the species of the entire hepatic vegetation. Jungermaniece are essentially distinct from Julrnlm by the following characters. Female flowers polygynous. Pedicel not at all, or scarcely, dilated at the apex—never into a segment of a sphere constituting a solid apophysis, nearly half the height of the cavity of the capsule, as in Jubulece
