Green. Branchlets of the female plant simple, those of the axil- 

 lary branches less large, and often collected into small glomerules. 

 Nucules covered with mucilage, placed about the middle of the simple 

 branchlets, with 6 to 8 striae, and with the spiral ridges on the central 

 cell scarcely prominent. Globules covered with mucus, solitary in 

 the forks of the rays, generally on the axillary branches, crowded 

 into compact glomerules, from the branchlets being extremely short.
