IX. ALGA?. 
[ Callophyllis . 
cate, 4-6 in. long, bright red, 2-3-chotomous or multifid ; segments narrow, 
linear, in. broad, pinnate on the margins ; pinnae like the segments, 
outer entire on the inner side above the sinus. Conceptacles immersed in the 
disk of the frond. — J. Ag. Sp. Alg. ii. 301. Sphcerococcus, Harv. Chondro- 
coccus, Kuetzing.

5. C. erosa, Hook. f. and Harv. FI. N. Z. ii. 250. t. 118. Frond 
crimson-purple, 6-12 in. long, sublinear, pinnately dichotomously decom- 
pound, densely or laxly branched ; principal laciniae in. wide, erect or 
erecto-patent, elongate, more or less compound ; margins with toothed or 
laciniate lobules or proliferous ; axils all rounded. Conceptacles sessile, mar- 
ginal, spherical.

6. C, asperata, Harv. in FI. N. Z. ii. 250. Frond rosy-crimson, 4-5 
in. long, delicately membranous, sessile, flabelliform, dichotomously palmate 
or decompound ; segments |-1 in. broad, broader upwards, crenate and 
multifid at the fastigiate tip ; margin flat or curved, fimbriate or often bear- 
ing cilia ; surface generally rough, with minute subulate processes. Concep- 
tacles immersed, scattered over the surface, convex. 
Port Nicholson, Lyall. 
77- KALLYMENIA, J. Agardh. 
Frond bright rose-red, broad, flat, ribless, between membranous and 
fleshy ; structure of 3 strata of cells, innermost of matted anastomosing fila- 
ments ; intermediate of large globular colourless cells ; cortical of minute 
vertically-placed coloured cells. Conceptacles immersed often prominent, en- 
closing compound masses of spores. Tetraspores eruciately parted, scattered 
amongst the cortical cells. 
Beautiful Algal, natives of both cold zones. 
1. K. Harveyana, J. Ag. Sp. Alg. ii. 288 ; — FI. N. Z. ii. 251. Frond 
membranous, 6 in. long, bright red, with a very short stipes, broadly obovate 
or orbicular-cordate ; margin entire, undulate. Conceptacles scattered over 
the whole frond, immersed, not prominent. — Euhymenia , Kuetzing. 
Blind Bay, Cook’s Straits, Lyall. (Cape of Good Hope.) 
78. GIGARTINA, Lamouroux. 
Frond dull purple or red, between cartilaginous and fleshy, flat or cylin- 
dric, simple or branched ; structure of 2 series of cells ; central, a lax net- 
work of cylindrical articulate filaments ; cortical of moniliform vertical dicho- 
tomous filaments imbedded in firm gelatine. Conceptacles globose, opening 
by a pore, enclosing several dense clusters of spores held together by a net- 
work of filaments. Tetraspores cruciatelv-partite, collected in sori amongst 
the filaments of the surface. 
A large genus, found abundantly in both cold, temperate, and tropical zones.
