East coast, Colenso ; Paroah Bay and Port Cooper, Lyall . — Very similar to, and easily 
mistaken for Callophyllis Hombroniana. 
46. ASPABAGQPSIS, Montagne. 
Frond filiform, red, inarticulate, panicled ; branches thyrsoid, penicillate, 
pinnately decompound ; branchlets setaceous, cellular. Conceptacles ovoid, 
enclosing a dense tuft of pyriform spores covered with a membrane. Tetra-

1. A. armata, Harv. — A. Delilei, FI. N. Z. ii. 233. Rhizome branched, 
setaceous. Fronds pale or bright rose-red, tufted, 6-12 in. long, much 
branched ; branches linear-lanceolate in outline, virgate, clothed to the base 
with short setaceous branchlets, and having also at the base a few long, naked, 
retrorselv spinous, stiff, spreading branches. Conceptacles globose, on cylin- 
dric stalks. — Harv. Phyc. Austr. iv. t. 122. A. Delilei, Harv. Ner. Austr.

In deep water, Cook’s Straits, Lyall. (Australia and Tasmania.) 
47. DELISEA, Lamouroux. 
Frond bright red, cartilaginous, narrow, compressed, 2-edged, much 
branched alternately; branches distichous, pectinate or coarsely serrate; 
midrib evident, immersed ; structure an axis of roundish-angular, colourless, 
close-packed cells, surrounded by several series of coloured, minute, cortical 
cells. Conceptacles ovoid, sessile on the midrib towards the tips of the 
branchlets, and enclosing a tuft of pyriform spores. Tetraspores immersed 
in wart-like swellings, spread over the tips of the branches. 
A southern genus, found hitherto only in Australia, New Zealand, South Africa, and Ker- 
guelen’s Land. 
1. D. elegans, Lamour. ; — FI. N. Z. ii. 233. Frond bright red, 6-12

pinnately decompound, all the branches and their divisions bordered with 
distichous, subulate, acute, alternate branchlets. Conceptacles solitary or 2 
together, sessile in the axils of the subulate branchlets, opening by a pore. —
