This species bears a very close resemblance to the ws ' 
It is calcareous, jointed, erect and about one inch in heigh > 
it grows in small and elegant tufts which are united 
each other by hollow, calcareous, black jointed tcndr' 
The root, immediately below the first internode is stra'g 
and narrow, but above is large and globular and > r ° 
its inferior surface numerous slender jointed tendrils P r ° 
ceed, embracing the surface on which it grows and fir' 11 > 
root it to the spot. It is dichotomously branched, and 
young specimens, the branches all arch inwards. The ce 
are biserial, semi-alternate, tubular, adnate, frequently r ° a »j 
or frozen, and speckled. The apertures are oblique, » 
slightly uneven. The joints are black, which give the p ol * s 
pidorn a speckled appearance ; the internodes are of van 0 
lengths and bear an unequal number of cells; below, 111 ' 
are narrow and gradually dilate into the two lower ce .* e 
Beside the hollow tendrils which form the roots, others 
from various parts of the polv pidorn near the joints, wb‘ 
are also hollow, jointed, and assist the rooting the p 01 - 1 
pidom to the spot. 
This is a more robust species than the last, and has ^ 
joints always black. The cells are sometimes promin e 
and the apertures divergent, as in the Crista eburnea, D 
as it is always black jointed and much stouter it cannot 
mistaken.
