2. E. siliculosus, Lyngbye ; — FI. N. Z. ii. 222. Fronds ^ in- long, 
olive-yellow, soft, decompound ; branches and branchlets alternate, ultimate 
elongate, distant, often secund. Silicules stalked, subulate, or conical and 
very acute, subsecund. — J. Ag. Sp. Alg. i. 22 ; Harv. Phyc. Brit. t. 162.

3. E. confervoid.es, Harv. in FI. N. Z. ii. 222. Fronds tufted, 2-4 
in. high, rather coarse, dense, not adhering to paper ; stems rigid, distantly 
branched ; branchlets few, simple, scattered, erect or patent, axils all acute. 
Silicules elongate, terminal, or imbedded in the branches. 
Cook’s Straits and Otago, Lyall. 
4. E. ? pusillus, Griffiths; — FI. N. Z. ii. 222. Fronds parasitic, 
tufted, pale brown, capillary, matted ; stems slender, long, simple or slightly 
branched ; branches distant, naked, horizontal ; articulations twice as long as 
broad in European specimens, much shorter in N. Z. ones. Spores (not seen 
in N. Z. plants) abundant, sessile, oblong. — Harv. Phyc. Brit. t. 153.

SUBORDER H. RHODOSPERMEA. 
32. LEN ORMANDIA, Sonder. 
Frond dull red, leaf-like, proliferous. Leaf-like branches flat, membranous, 
simple ; midrib evident, surface striated obliquely ; substance honeycombed 
with rhomboidal cavities ; surface-cells minute. Conceptacles scattered, 
stalked, enclosing pyriform spores. Stichidia lanceolate, containing 3-partite 
tetraspores. 
A small Australian and New Zealand genus. 
1. L. Chauvinii, Harv. in FI. N. Z. ii. 222. Leaves 1|— 3 in. long; 
-p-g — §■ in. wide, dark purple when fresh, thickish, rigid, and semi-opaque 
when dry, shortly stalked, broad, linear-oblong, obtuse, quite entire; nerve 
slender, evanescent, proliferous. Stichidia thickly fringing the margin or on 
the nerve, lanceolate, simple or multifid. 
East coast, Colenso ; Otago, Lyall. — Harvey says of this, that he first received it from 
New Holland, but I do not find it in his enumeration appended to the ‘ Phycologia 
Australis.’ 
33. EPINEURON, Harvey. 
Frond dark red, flat, linear, toothed or ciliated, membranous or horny ; 
midrib evidently distichously branched, transversely striate ; interior of large 
angular colourless cells ; cortical of many series of minute coloured cells. 
Stichidia lanceolate, incurved or circinate, placed on the costa, containing 2 
rows of tetraspores. 
A small genus, of medium-sized southern Alga. 
1. E. Colensoi, Hook. f. and Harv. FI. N. Z. ii. 223. Frond red-
