De s c r . Boot discoid. Eronds 6-12 inches high, cylindrical, filiform, much
branched Main stem from half a line to a line m diameter below, gradually
attenuated upwards, undivided, or variously cleft, or subdichotomous, beset
witb very numerous, quadrifai'ious, lateral branches. Branches^ alternate, or
issnino- irregularly, very various in length, simple, or slightly divided, bearmg
a second or tlmd set of similar but shorter and more slender branclilets ;
which, including all the younger parts of the frond, are beset on all sides
with minute, slender ramuli, tapering to each end, and 1 -2 lines in length.
The stem and branches are soHd, composed internaUy of very large, hyaline,
polyo-onal, ceUs, surrounded by others of smaU size, and a periphery composed
of minute cellules. The large interior ceUs, seen thi-ough the coat of
the frond give the sm-face, under a low power of the microscope, a reticulated
appearance. The ramuli consist of whorls of horizontal, radiating,
diohotomous, jointed filaments, closely packed together, and issmng from a
slender, cellular axis. When in fructification, the ramifii become wider m
the middle, taking a spindle shape, aud spores of an oblong, pyriform shape,
are formed at the bases of the whorled filaments. The colour is a brilliant,
rose-red, the substance gelatinoso-membranaceous, aud the plant adheres to
paper in drying.
This chaTmiiig plant, as rare as it is beautiful, was discovered
