great, to the naked eye it appears nearly bare, but by higher 
magnifying powers small tufts, like those terminating the 
subramuli, appear at about every ten cells; some larger, and 
approaching somewhat the subramuli, while the others are 
very simple. The larger terminal and lateral tufts have 
a pyramidal form, and from all their divisions proceeding at 
right angles, it appears much like a fir tree. 
All the ultimate tufts bear cilia, as in the other Drapai - - 
naldiae, but of extreme length and tenuity in this species. 
From the 1 — 3 basal cells of the ramuli, often roots, spring, 
coiling themselves round the main filament, and even 
spreading away from it, and sometimes the free point becomes 
converted into a tuft, like those on the main filament. 
The smaller tufts at times possess them. When the plant is 
mature the ramuli disengage themselves and can be seen 
floating about with their roots probably ready to attach 
themselves to any suitable object, and so become separate 
plants. 
This, as the other Draparnaldia?, produces zoospores which 
are not so large as in D. glomerata, being oval and about -g-pro 
inch long diam., and about 3 .^ -o inch of short diam., with a 
cilia. A whole tuft undergoes the process simultaneously. 
This species is found in the small streams rising from the 
bogs in the New Forest. It was found in June in 1853, and 
in July in 1855, associated with a Batrachospermum, which it 
much resembled at first glance. It attaches itself to sticks, 
stones, &c. 
It can ^easily be distinguished from D. plumosa, glomer., 
and rep., by the divisions diverging at right angles, and in 
whorls of chiefly four (giving the cruciate appearance), the 
perceptible mucous sheath (bringing it near to Chsetophora) , 
the exceeding delicacy of the cilia ; extreme tendency 
to give out radicles ; the nearly equal of width of the 
main cells, as also their greater length. The fir-tree-like 
form of the tufts are so unlike the flexible shape of the 
other species.
