This Plant* grows in rather densely-matted patches of various, but generally considerable, extent. 
Roots simple whitish fibres, which descend here and there from nearly the whole length ot 
the under surface of the plant. 
Stems from an inch to nearly three-quarters of an inch in length, filiform, somewhat 
flexuose, rarely simple, mostly once or twice irregularly divided, with rather slender and 
simple branches, which gradually lessen towards the extremity. Innovations also 
resembling these, but still more slender, are frequently produced. The texture of all of 
* Fertile specimens seem to be the most crowded in their mode of growth, and 1 possess, from Mr. Lyell, a tuft, 
which forms almost an entire mass of calyces.
