A foliis involucralibus cum perianthio altius concretis diagnosin desumpsi, sed forsan liaec forma species sui juris inter Jungermanniam hyalinam et obovatam quasi inter- jecta est, quod observationibus futuris dijudicandum erit.] 111. - ISOTACHIS Mitten (reformat.). Perianthium terminale crassius (e 3-7 cellularum stratis com- positum) cylindrico-conicum, apice plerumque dealbato dentato squamulis dentatis purpurascentibus vel decoloribus obvelatum. Involucri folia (ad speciem) intima minutissima 3 quasi abortiva perianthio adulto disperse accreta eique arcte adpressa. Calyptra inclusa libera, membranacea, pistillis abortivis basi et altius stipata. Capsula oblonga, firma ad basin usque quadrivalvis, valvulis aut rectis aut tortilibus dehiscens, interne fibris semicir- cularibus depicta. Elateres valvulis ubique insidentes, caduci, bispiri. Semina fusca, laevia. Inflorescentia mascula in planta diversa; perigoniorum spica vel in apice vel in medio ramo foliis majoribus composita, vel amentacea in ramis microphyllis, in axillis unicum antheridium continentibus. Caules erecti, arrhizi; folia conduplicata cuticula tam laxe vestita ut cellulae singulae rugulosae appareant; amphigastria magna foliis subcon- formia. Plantae mediocres aut grandiusculae, saepe roseae vel purpureae, in caespitibus densis crescentes. Ex Jungermdnnia madida, serrvlata, uncinata et congeneribus cl. Mitten novum genus, Isotachidem suam, condidit, quod in Flora Novae Zelan- diae, p. 1/i9, liisce verbis definivit: « Perianthium terminale, tubulosum, ore contracto dentato. Caulis » erectus, innovationibus ramosus. Folia incuba, amphigastria fere con- » formia, conduplicata, saepe serrulata. » Quibus adjecit: « The above appears to be ali that may be safely affir- » med ot’ this genus. It is readily recognized by its evenly arranged leaves » and stipules, which last so nearly resemble the leaves in size and form, » that the foliage might almost be called trifarious. The perfect capsule » has been seen only in two species, in one of which it is spirally twisted, » and in the other perfectly even and straight. This Genus is distinguished
