H a b . Georgetown, rare. Archer, R . Gunn.
Three to four inches high, divided from the base into numerous brancbes. Branches as thick as hog’s-bristle,
pellucidly articulate, often naked near the base, closely pinnated and feather-like beyond the middle. Some of the
larger branches divide, and each division is then pinnate. Pinnæ inch long, distichous, pateut, abont a line
apart, each subtended by a ramellus, wbich is pectinate on its inner face. RamelU mostly in pairs alternately,
robust, patent or strongly reflexed, pectinate, the teeth of the comb horizontal, little tapering, but suddenly mucronate
at the apex. Colour rosy-red.—This looks almost like a small specimen of B. Muelleri, but differs iu the
nature of the ramelli. the greater transpai-ency of the branches, the subtending ramellus to the pinnæ, etc. We
have only seen three specimeus.

We know notliing of tliis plant, which is said closely to resemble Crouania attenuata. Can it be a Crouania,

Fi-onil 2 feet long or more, very soft and flaccid, twice as thick as hog’s-bristle, excessively branched in an
alternate manner, the main branches long and virgate, the rest successively shorter. AU parts are more or less
flexuous, or gracefully bending. The cilia are longer, more filiform, more distant, and less regularly placed than in
B. elegans, and in the lesser division a cilium is frequently lengthened to twice or thrice the ordiiiaiy length, and
then pectinated on its imicr face, The whole plaut has more the aspect of a Hypnea thau of a Belisea, but the
fructification is exactly that of B. elegans.
