in outline, flabellate, 2-edged, in. broad, decompoundly pinnate ; pinnae 
alternate ; pinnules pinnatifid, ultimate serrate or pectinate. Spore-masses 
sessile, with 4 pectinate involucral branchlets. Tetraspores marginal, pedi- 
celled, globose. — ¥1. Autarct .190. t. 77 ; J. Ag. Sp. Alg. ii. 102. Euptilota, 
Kuetzing. 
Throughout the islands, and in Iiord Auckland’s group, abundant. 
2. P. pellucida, Harv. in FI. N. Z. ii. 257. Frond bright rosy-red, 
2-3 in. long, ovate in outline, filiform, distichously decompound, primary 
branches 2-3-pinnate, not coated with cells above ; pinnae articulate, opposite, 
unequal, one undivided, the other pinnate or pectinate on one side ; ultimate 
branchlets filiform, constricted at the base, subacute ; articulations 1|— 2 
times as long as broad. 
Otago and Stewart’s Island, Lyall. — Harvey suggests the possibility of this being the 
same as the Callothamnion Ptilota, 3)1. Antarct. t. 189, found off the Crozet Islands. 
94. GRIFFITHSIA, Agardh. 
Frond rose-red, filiform, dichotomously branched, articulate, of one tube ; 
branchlets often whorled; nodes transparent. Spore-masses involucrate, en- 
closing numerous angular spores. Tetraspores globose, 3-parted, involucrate. 
A considerable genus, found in both temperate zones. 
1. G. setacea, Agardh; — FI. N. Z. ii. 258. Frond 3-6 in. long, se- 
taceous, rather rigid, straight, irregularly dichotomous, crimson ; axils acute ; 
branchlets sometimes opposite ; articulations cylindric, 5-6 times longer than 
broad; involucres lateral, pedicelled. — Harv. Phyc. Brit. t. 184 ; J. Ag. Sp. 
Alg. ii. 84. 
East coast, Colenso ; Foveaux Straits, Lyall. — A state with more slender branches and 
longer articulations has been found at Bluff Harbour and Port Cooper, Lyall. (N. and S. 
temperate oceans.) — A beautiful plant, stains paper crimson; when put in fresh water the 
articulations burst with a crackling noise, and discharge the red colour. 
2. G. antarctica, UooJc. f. and Harv. FI. Antarct. ii. 488 ; — FI. A. 
Z. ii. 258. Frond tufted, flaccid, stout, dichotomous; branches elongate, 
erect, and branchlets often secund, naked, constricted at the nodes ; articula- 
tions of the branches 4-6 times, of the branchlets about 3 times longer than 
broad ; fruiting branchlets lateral, short, crowned with an umbellate invo- 
lucre. — J. Ag. Sp. Alg. ii. 87. 
East coast, Colenso ; Foveaux Straits and Stewart’s Island, Lyall. (Tasmania.) 
95. BALLIA, Harvey. 
Frond bright or rose-red, fading to green or dirty brown, filiform, rigid, 
dendroid ; stem and branches covered with short capillary fibres ; branchlets 
pellucid, pinnately decompound, or pectinately pinnate. Spore-masses en- 
closed in an involucre of many incurved filiform branchlets, containing nume- 
rous angular spores. Tetraspores on the short capillary fibres of the branches. 
A small genus of beautiful plants.
