Jungermannia frondibus suborbiculatis palmatis dicho-

Caudex horizontaliter repens, nigro-fuscus, radicibus tomentosis 
hic illic obsitus. Stipes biuncialis, erectus, flexuosus, sub- 
compressus, fuscus. Fons fusco-viridis, membranacea, pul- 
cherrime reticulata, palmata, segmentis linearibus, dichotomis, 
dichotomiarum angulis patentibus, radiato-expansis, ita ut 
frondis totius ambitus sit subrotundus, margine integerrimis, 
apice obtusis, nervo fusco, validiusculo percursis. Fructificatio 
in dichotomiarum axillis, Calya duplex, ext. perbrevis, bi- 
labiatus, labiis patentibus: iz, oblongo-cylindraceus, carnoso- 
membranaceus, ore aperto, brevi-laciniato, laciniis denticula- 
tis. Seta subsesquiuncialis, Capsula 4-valvis, valvis linea- 
ribus, apice filamenta spiralia, longa, ex helice duplice constan- 
tia, gerentibus. 
There can be, I think, no doubt of this being the J. flabellata 
of Labillardiére, although I cannot find that the exterior calyx 
in my specimens accords with what he has represented. With 
respect to the shortness of the interior calyx, as described by 
M. Labillardiére, that is in consequence of its being in a young 
state, for he was not acquainted with the perfect fructification. 
As in J. Lyellit and hibernica (with which this plant has many 
points in common), this part increases in size as.the fructifieation 
advances,
