obliteratis), in paucissimis compresso-planum ; apice in mucronem 
tubularem abiens, demum valvatim fissum. Calyptra libera, in 
Lejunea tenuis, in Frullania carnosa, obovata pyriformisve, apice 
subregulariter bi-trivalvatim rupta. Pedicellus perbrevis, perian- 
thium 2-3plo (interdum vix) superans, apice in capsulam abrupte 
dilatatus. Capsula globosa, pro more tenuis, a media basi ad 4 
semicircumferentiz# usque integra, intus pallida, deinde 4-valvis, 
valvulis ovali-lanceolatis acutis, alternis subangustioribus, facie

reliquiis?) reticulate. Hlateres haud numerosi (16-200), capsule

CoNSPECTUS GENERUM J UBULEARUM. 
A. Lobulus foliorum a caule plus minus dissitus, plerumque saccatus yal- 
ealusve, interdum evolutus et recurvo-canaliculatus. 
I. FrutiuanrA.—Rami intra-axillares, folii caulini basi imterna con- 
tigui, ab eodem liberi. Folia subtransversa, valida, pro m. integerrima ; 
cellule pariete incrassato, trigonis angularibus sat magnis. Foliola con- 
stanter preesentia. Innovatio subfloralis nulla. Flores 9? 2-4-gyni, 
bracteis plurijugis. Pedicellus cellulis 4-stratis concentricis (8 ¢. in 
sectionis diametro, 32 ¢. in circumferentia) subequalibus alternis con- 
flatus. Capsula facie interna papilloso-spongiosa. 
Il. Jusuta.—Rami laterales, folio unilobo, antico, ex p. in caule, ex 
p- in ipso ramo insidente, suffulti. Folia super caulem_ incurrentia, 
tenella, ciliata, cellulis subleptodermibus conflata. Foliola preesentia. 
Flores 9 1-4-gyni. Innovationes subflorales duz, opposite, altera
