Summer. Duddingston Loch, near Edinburgh, abundant.
Frond globose, mostly about the size o f a small pea, b u t sometimes nearly
as large as a hazel-nut, solid, more or less of a green colour. Filaments
dense, numerous, radiating from the centre to the circumference, dichotomous,
fastigiate, th e joints about twice as long as they are broad,
green in the centre, diaphanous at the articulations. Substance firm,
(except in old large plants), and gelatinous. (Large, dark-coloured, somewhat
irregular granules are scattered here and there among the filaments,
to which they seem to be attached).
A pretty little plant, certainly the same as that described
