ALGJE OF TASMANIA. 433 
another series is probably borne. All the divisions are alter- 
nate, and generally a considerable space intervenes between 
both branches and branchlets. The branches like the stem 
are naked ; the branchlets alone, which diminish in size from 
the base to the apex of the branches, are furnished with the 
filamentous articulate ramelli characteristic of the genus. 
These ramelli are very minute, scarcely 1 of a line long, hori- 
zontally patent, whorled, rising from broad bases or slightly 
foliaceous expansions, many times dichotomous, with patent 
axils; their lower part thick, with short joints, the upper 
gradually attenuated, with long joints. Stichidia borne on 
the ramelli, sessile, oblong, subobtuse or slightly mucronate, 
containing a double row of 3-parted tetraspores. Colour 
of the frond pale red, of the ramuli rosy.—The habit of 
this plant is something like that of Naccaria Wigghii, es- 
pecially in the clubshaped branchlets; but it is a true species 
of Dasya.

—BStem 12-14 inches long, excessively branched and bushy, 
the lower branches often as long as the stem, many times 
divided in an alternate, but not distichous manner. Branches 
crowded; they, and all parts of the frond except the older 
portions of the stem densely clothed with exceedingly slender 
quadrifariously inserted, scattered, articulated filaments or 
rTamelli, These are neither whorled nor pencilled at their 
. insertion, but, though crowded, are scattered irregularly over 
the surface, erecto-patent, 2-3 lines long, repeatedly, but 
rather distantly dichotomous, with joints about 4 times as 
long as broad. Colour a dark vinous red, becoming brown-
