105. BATRACHOSPERMUM, Roth. 
Frond immersed in gelatine, filiform, branched, usually moniliform and 
nodose, longitudinally striate, composed of colourless jointed filaments agglu- 
tinated together, beset with distant whorls of moniliform branchlets. Spores 
in globular masses seated on the whorls. 
Delicate filamentous freshwater Algae, growing in subalpine lakes and running streams. 
1. B. moniliforme, Roth; — FI. _ZV. Z. ii. 261. Vaguely branched, 
variously coloured (green purple violet brown or blackish) ; nodes monili-

106. CLADOPHORA, Kuetzing. 
Frond green, filiform, dichotomously branched, articulate, uniform through- 
out ; articulations of single long or short tubes, filled with granular endo- 
chrome, that at maturity developes antherozoids. 
A large and widely-diffused genus. 
§ 1. Filaments forming dense intricately-matted masses. 
1. C. herpestica, Kuetzing ; — FI. N. Z. ii. 262. Filaments tufted, 
creeping, ultra-setaceous, bladder-like, rigid, irregularly branched ; upper-

2. C. Lyallii, Harv. in FI. N. Z. ii. 262. t. 121 G. Filaments pale 
yellow-green, forming dense wide-spreading matted tufts, stout, rigid, de- 
cumbent below, then erect, f— | in. long, very irregularly branched ; branches 
spreading, secund or opposite or alternate ; branchlets few, 3-4 articulations, 
which are constricted at the nodes, and If times as long as broad.

below, forming an intricate spongy compact mass, capillary, rigid, excessively 
branched ; branches erect, lower simple, upper dichotomous ; branchlets sub- 
secund, acute, spiniform, straight or hooked ; articulations as long or twice 
as long as broad.
