Lembidiuin— Odontochisma / 59 



Cephatozia heteromorpha (Lehm. Hep. Cap. sub Jung. a. 1829; Syn. Hep. 131) 

 foliis subrotundis concavis laxe textis, aliis subemarginatis, aliis integris, G. Boschii 

 certe proxima, differt caule eflagellari et foliolis vel subulatis integris vel ovatis 

 bidentatis.— [^Mw^. rhizantha Mont, in Crypt. Cub. G. hetermorpha vicina dicitur, 

 foliis autem ad J usque bilobis, lobis (idem ac bractearum) obtusis, exemplum G. 

 Jiuitantis extenuatum simulare mihi videretur.]

 Lindenb. et G. Spec. Hepat. 20, t. 22, mihi nonnisi sterile visum. Species autem sine 

 dubio Ceph. Boschii congener est, caule crasso diametro 8 cellulas lato, cell, corticis 

 24-seriatis, internis conformibus;* foliis latis concavis, etc.; difteri^orescentia dioica ; 

 caule basi magis ramoso et flagella validissima demittente ; foliis confertissimis 

 fragillimis transversis, subincubis, (antice sese paulo latius quam postice imbric- 

 antibus) apice bifidulis ; foliolis majoribus, apice bidentellis vel paucidenticulatis. 

 Cellules in folii medio basique magnae oblongo-4 — 6-gonae pellucidae, superiores et 

 submarginales triplo minores hexagonae aequilaterales opacae (chlorophyllo in cellulse 

 angulis concervatoj facillime disruptse. — Altera species est Lembidium ventrosum

 apice rotundatis retusulisve concavissimis, cellulis minoribus ; foliolis triangularibus 

 subemarginatis ; ramulo fcem. Insigniter incrassato, &c. — Omnes haec, Ceph. 

 rhizantha excepta, sine dubio arete affines sunt, hinc cum Eucephalozlfs subluridis, 

 illinc cum Odontochismatibus osculantes ; caracteribus suis (primo visu genericis) 

 omnibus in aliis CephalozicB subgeneribus vel constanter vel casu obviis ; sc. bracteis 

 perianthiisque carnosis in C. crassiflora, perianthiis solis in C. Francisci ; ramis 

 nutantibus et foliis pro more integris in C. ( Alobiella) lancifolia ; foliis transversis in 

 pluribus, &c. &c.; ideoque genus proprium vix sistentes.

* Mitten, in Hooker's 'Handbook' 1. c. attributes "a loosely cellular coat" to the stem. There is 

 however none such, and the "looseness" exists solely in the author's perceptions.
