sight of some of Dumortier’s originals, but in vain. Having
convinced myself of the distinctness of C. multiflora (nob.) from
C. connivens, I sought for some notice of the former in the works
of previous authors, and it seemed to me possibly identical with
C. lunulæfolia Dum. The name suited well enough—not so well
the meagre diagnosis. The first question I asked M. Delogne
was about this plant, and he has been good enough to send for
my inspection two specimens from the herbarium, the one marked
hy Dumortier (in the earlier part of his career) Jg. lunulata Dum.,
the other Ceph. lunulæfolia Dum. The latter from the classic
exsiocata of Moue, and Nestler is conclusive.C5 I am Og lad of this,’
as it gets rid of two names, mulfiflora and media, which were likely
to lead to a fight.”

Monoicous, cæspitose, flagelliferous, small to medium in size,
pale gi'een, dull white or rose coloured. Stem prostrate, or
ascending, irregularly ramose, branches few, postical ; flagella
radiculose ; rootlets few, more frequent on the fertile branches ;
cortical cells about 10, large, pellucid, inner about 6 in diam., smaller
subopaque. Lower leaves smaller and distant, upper larger and
subimbricate, diagonal at base or where closer, almost transversely
inserted, ovate-orbicular, bilobed to about the middle, concave,
sometimes complicate, segments connivent or patent, ovate-
lanoeolate or subtriangular, postical acute, antical a little
narrower, sub-acuminate, sometimes shortly apioulate ; cells rather
large, 4-, 5- and 6-sided, pellucid, no trigones or thickened angles.
Stipules wanting, except rarely on the female flowers. Inflorescence
clado-acrooarpous ; branohes ¥ very short, rarely more or
less elongate. Bracts about 3 pairs, innermost almost 3 times
longer than the leaves, partly free, to the middle bilobed, segments
lanceolate acuminate, entire or towards the base 1-2 spinose,
rarely sublaciniate; bracteole similar; sub-bracts smaller, roundish ;
sub-bracteoles also smaller, lanceolate, spinulose, rarely bifid,
sometimes obsolete. Perianth 4 times longer than the leaves,
linear, prismatic, or subfusiform, mouth constricted or rarely
open, denticulate, setulose or ciliolate ; at first trioarinate at
the base, when older suhterete, above trigonous, areolation lax,
pale green or white, sometimes below of a beautiful purple colour,
apex canescent, the whole length (except at the very base, which
is 2, 3 cells thick) composed of a single layer of cells, about 60
cells round. Calyptra small, delicate. Pistillidia about 12,
small. Capsule oylindrical-oblong. Spores purple. Androeoia
spicate, perigonial bracts situated at the apex or middle of the
branches, or occupying the whole length, very rarely immediately
below the ? flowers, closely imbricate, ascending, similar to the
leaves, but broader at the base, which is swollen, sometimes v/ith
a third, small, antical tooth. Antheridia oval, single.
