1. N. ramulosum, Harv. in FI. N. Z. ii. 245. Frond 6 in. long, 
in. broad, compressed, once or twice forked, irregularly densely set with 
spreading branches and branchlets ; branches unequal, 1-2 in. long, hori- 
zontal, obtuse, simple, or again set with lateral often forked branchlets. 
Fructification unknown. 
Otea, Lyall. 
68. SCINAIA, Bivona. 
Frond red, terete or compressed, dichotomous, between gelatinous and 
membranous, filled with fluid gelatine, traversed by a fibrous axis, from which 
slender branched filaments radiate to the periphery, which is formed of a thin 
stratum of small angular cells. Spore-masses globular, of jointed spore- 
threads, enclosed in a membrane, suspended on the inner wall of the frond, 
bearing pyriform spores. 
A genus of only one known species. 
1. S. furcellata, Bivona; — FI. N. Z. ii. 245. Frond tender, rose or 
lake-red, 2-4 in. long, cylindric, diameter from a sparrow’s to a swan’s quill, 
branched, with a semicircular outline ; tips and axils obtuse. — J. Ag. Sp. Alg.

East coast, Cunningham ? (Europe, N. America, Chili, Pacific, Tasmania, S. Africa.) 
69. WRANGELIA, Agardh. 
Frond rose-red or purplish, filiform, articulate, branched, of a single tube, 
sometimes coated with minute cells ; branchlets minute, opposite or whorled 
round the nodes. Spore-masses usually involucrate, containing several clusters 
of spores in the uppermost whorls of the branchlets. Tetraspores 3-parted, 
scattered on the branchlets. 
A beautiful small genus, native of both temperate zones. 
1. W. Lyalin, Haro, in FI. N. Z. ii. 236. Frond flaccid, carmine-red, 
setaceous, 4-5 in. long, pinnate or 2-pinnate, pellucid above, veined near the 
base ; branchlets elongate, articulate, simple, with whorled or opposite branch- 
lets at the nodes ; branchlets pinnate ; articulations not coaled writh cells ; 
walls thick, of the branches many times longer than broad. Tetraspores 
sessile on the inner faces of the branchlets, 1-2 at each node. Spore-masses 
minute, terminal, hardly involucrate. 
Ruapuke and Preservation Harbours, Lyall. 
2. W. (?) squarrulosa, Harv. in Fl. N. Z. ii. 236. Frond rigid, seta- 
ceous, articulate throughout, distichouslv branched ; branches opposite and 
alternate, very compound, loosely divided or closely pinnate or 2-pinnate ; 
pinnse usually opposite ; branchlets minute, squarrose, whorled, clothing the 
nodes, dichotomously multifid, spinescent ; articulations 2-3 times longer 
than broad, not coated with cells. Tetraspores sessile on lateral branchlets. 
Preservation Harbour, Lyall. — Dr. Harvey describes two varieties, both gaihered on the 
same spot, one pinnate with the pinnae opposite aud very close ; the other vaguely branched, 
scarcely pinnate. The genus is doubtful, the spore-masses being unknown.
