aspect, and ramification, 3-6 in. long, pinnately-decompound, woolly, cau-

Frond slender, several inches long, filiform, sparingly branched, inarticulate, 
bearing dense spherical tufts of fertile filaments or branchlets throughout its 
whole length and on all sides ; branchlets of the tufts incurved, dichotomous, 
bearing lateral sessile spores. 
East coast and Cook’s Straits, Lyall. — Harvey suspects that this curious plant, of which 
we have imperfect specimens only, may prove a state of S. paniculata.

Fronds forming dense hemispherical or globular brown or olive-green patches 
■Jj- -i in. diameter ; filaments rigid, arcuate, simple or sparingly branched, 
brown at the tips; branchlets erect, often secund; articulations of about 3 
cells. Spores secund, rarely opposite, pedicelled, ellipsoid-oblong. 
Parasitic on Carpophyllum Maschalocarpus, Colenso. 
31. ECTOCARPUS, Lyngbye. 
Frond flaccid, olive or brown, capillary, jointed ; joints of a single cell, not 
striated. Spores spherical or elliptic, external or imbedded. Lanceolate 
linear or conical bodies (silicules) also occur, and granular masses formed in 
connective cells of the branches. 
A very large genus in the northern hemisphere, of small annual Algce.
