the branches arise variously from the mid axil of a leaf, or from 

 its postical angle, and the female flowers are borne on the apex of 

 the stem or of long leafy branches ; there are no stipules at all, 

 except very rarely a small subfloral one ; the bracts are distichous, 

 conformable to the leaves, and usually remote from the perianth 

 (whence the species becomes the type of Dumortier's spurious 

 genus Gymuocoleci) \ and the perianth itself is pyriform, inflated, 

 and obscurely 4-5-plicate, only at the very apex ; it is besides 

 composed of 2 strata of cells up to \ of its height."

Dioicous, depresso-ca?spitose, flagelliferous, from a reddish- 

 brown to a dull brown or green, sometimes orange colour, fragile. 

 Stems intricately flexuose, radiculose, rootlets produced the whole 

 length of the stem, white ; simple or twice dichotomously branched, 

 with the young apex almost always bifurcate, sometimes, not 

 always, producing radiculose, stoloniferous, postical branches 

 partly leafy, rarely altogether leafless. Cells of the stem 7 or 8 

 in diameter, cortical 20-22, subquadrate, subopaque, inner some- 

 what smaller, more pellucid. Leaves diagonally inserted at the
