Colvend, Dumfries-shire, Dr. Richardson. © . Spring — Fronds gregarious,
4—9 inches long, and scarcely half a line in diameter, attenuated
at both ends, regularly compressed, of a firm substantial texture and
deep chestnut colour. No fructification has been detected on it.—
have no doubt that this is a distinct species from A.fistulosus, with which
alone there is any chance of its being confounded. Besides being compressed,
its texture is much firmer and more substantial, and its colour
deeper. Carm. MSS.
3. A. ? pusillus, (least Asperococcus); frond rounded capillary
spuriously articulated brown. Carm. 31SS. cum Ic.
On Chorda Filum, Appin, abundantly, Captain Carmichael. Meadfoot,
Devonshire, Mrs, GriJJi/hs. ©. Autumn.— The fronds of this
diminutive species are so closely aggregated as to give to a section of the
plant on which they grow, the appearance of a bottle-bru.sh. They are
from 1 to 2 inches long, simple, the thickness of horse-hair, attenuated
at both ends, transversely striated in imitation of joints andclo.-ely beset
with pellucid fibres. Carm. MSS.
4. A. Tumbrii (Tumerian Asptrococeus); frond oblong cylindrical

©. Summer.— Mrs. Griffith* remarks of this plant, that it is nol ren
conspicuous when growing in the water. The cavitj being filled with
thai fluid and the substance thin and transparent, it appear-, to be ot
the colour of the water itself, and then tore not easily M * D, unless the
light he catl upon it in a particular manner.
