Monoecious. Bright green or olive. Stem slender or moderately 

 stout, flexible, translucent or rarely opaque from being encrusted with 

 carbonate of lime, without cortical cells or spine-cells ; stipule-cells in 

 one whorl, of the same number as there are branchlets in a whorl, 

 and alternating with them, very short, spreading, acute. Branchlets 

 7 to 11 in a whorl, ascending, or slightly incurved, without cortical 

 cells, 3- to 5-jointed ; their joints of nearly equal length, the terminal 

 joint tipped with from 2 to 5 minute acute cells. Bracts 3 to 10 in a 

 whorl, those on the inner side of the branchlet usually shorter than 

 the nucules, but sometimes as long or longer ; those on the outside of 

 the branchlet shorter than the inner ones, rudimentary, or altogether 

 deficient, especially at the sterile nodes of the branchlet. Nucules in 

 the axils of the bracts at the 2 or 3 lowest nodes of the branchlets, 

 solitary, or in pairs, or at the lowest node sometimes 3 together, ovoid, 

 9- to 11-striate, with a short erect, somewhat spreading, or connivent 

 crown, when ripe of a brownish-yellow colour with a blackish nucleus. 

 Globules solitary or in pairs placed immediately beneath the nucules.
