J\. ALGjE. 
103. ENTEROMOEPHA, Link. 
Frond green, tubular, hollow, cylindric or compressed, usually branched ; 
. structure reticulated. Fructification of roundish spores in threes or fours, 
clustered in the reticulations. 
An excessively common genus of annual Alga, found in all seas, and in brackish water 
also. The two first species appear to pass into one another, and often to he difficult to dis- 
tinguish from TJlva. 
1. E. compressa, Grev. FI. N. Z. ii. 264. Frond very variable, 
6-12 in. long, elongate ; branches cylindrical or compressed, firm, capillary 
2-j in. diameter ; branches simple or nearly so, attenuated at the base, ob- 
tuse.— Harv. Phyc. Brit. t. 335. 
Abundant on the seashores. (Common in all seas.) 
2. E. intestinalis, Grev. ; — FI. N. Z. ii. 264. Frond 2 feet and more 
long, T \-3 in. diameter, simple, tapering downwards, inflated, often floating, 
often waved and curled, full of green-coloured fluid, fading to yellow and 
white. — Harv. Phyc. Brit. t. 154. 
Abnndant on seashores, with E. compressa. (Common to all seas.) 
3. E. clathrata, Grev. — Var. ramulosa, FI. N. Z. ii. 265. Frond 5 in. 
to 2 feet long, very slender, much branched, highly reticulated, curled and 
twisted, forming a dense interwoven mat, beset on all sides with short spine- 
like branchlets, hence harsh to the touch. — E. ramulosa. Smith ; Harv. Phyc. 
Brit. t. 245. 
Var. erecta. Branches all attenuated to a fine point. — E. erecta, Harv. Phyc. Brit. t. 43. 
Zignoa, Trevis ; Mont, in Voy. au Pole Slid, t. 30. 
Var. ramulosa, Otago Harbour, Lyall. Var. erecta, Lord Auckland's group, D'Urville. 
(Europe, etc.) 
104. BANGIA, Lyngbye. 
Frond generally pink or purple, capillary, tubular, simple or branched, of 
numerous radiating cells in transverse rows, enclosed in a hyaline sheath. 
Fructification of purple or green spores, one in each cell of the frond. 
A considerable genus of very small fresh- and salt-water Alga, often forming a scum or 
stratum on rocks, walls, etc. 
1. B. ciliaris, Carmichael ; — FI. N. Z. ii. 264. Filaments minute, 
simple, straight, J in. long, variable in breadth, compressed, purple, some- 
times expanding and leafy in the middle ; cells in 2 rows except where ex- 
panded, globular.— Harv. Phyc. Brit. t. 322. 
Parasitic on leaves of Zostera, Cook’s Straits, Lyall. (Europe, also on Zostera.) 
2. B. lanuginosa, Harv. in FI. N. Z. ii. 264. Filaments curved, 
cylindric, bright purple, soft, gelatinous, of one series of lenticular cells, 
which are shorter than broad. 
Parasitic ou Chordaria, Colenso.
