out bracts. — Atl. Fl. Par. 39 (not good). — Slender, diaphanous, 
resembling C.Jlexilis. Nucules with 5 striae and scarcely any 
crown.— Stagnant water. A. V. E. S. I. 
** Branchlets usually repeatedly diviaea, termvnal segtnents of 2 
joints, last joint tisiially like a mucro. BranchleU 6 — 8 in a 
whorl, similar. 
3. C. transhicens (Pers.) ; monoecious, st. thick equal flexible 
transparent, sterile hranchlets simple not jointed, vpper ones 
ending in 2 or 3 short points, fertile whorls of small trifid branch- 
lets very small and closely placed, nucules small oblong usually 
in threes just below the prongs of the branchlet which sun-ound 
the terminal globule.— jE. B. 1855. Atl Fl. Par. 40 B.— Strong.

with 7 striae. — Beep stagnant pools. A. VII. E. S. I. 
4. C. mucrmwta (A. Br.) ; monoecious, st. slender equal flex- 
ible transparent, hranchlets strongly mucronate neai'ly equally 
forked or trifid, tmcules and globules together at the forks of the 
hranchlets without bracts. — Atl. Fl. Par. 40 D. — Rather thick. 
Secondary hranchlets once or twice forked, teiminal subdivisions 
rather shorter than the others. " Nucules with 4 or 5 striae." —
