Caud,ex horizontaliter repens, nigro-fuscus, radicibus tomentosis
hic illic obsitus. Stipes biuncialis, erectus, ilexuosus, sub-
compressus, fuscus. Frons 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. Fructijicatio
in dichotomiarum axillis. Calyx duplex, ext. perbrevis, bi-
labiatus, labiis patentibus: ¿raL oblongo-cylindraceus, carnoso-
membranaceus, ore aperto, brevi-laciniato, laciniis dentieula-
tis. Seta subsesquiuncialis. Capsula 4-valvis, valvis linearibus,
apice iilarnenta spiraha, longa, ex helice duplice constantia,
gerentibus.
There can be, I think, no doubt of this being the J .fla h e lla ta
of Labillardiere, 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. Labillardiere, that is in consequence of its being in a young
state, for he was not acquainted with the perfect fructification.
As in J . L y e llii and hilernica (with which this plant has many
points in common), this part increases in size as the fructification
advances.
