RHIZOMORPHA Stokesii.
Found in the Challc at the Sand-pits at Blackheath Hill, by Charles Stokes, Esq. in 1811. It is in flat reticulated entangled masses, the main stems compressed, forming various angles, and the shoots and branches nearly at right angles, rounded, and bluntly ended. The Chalk sometimes adhere* to the roughish or more wrinkled surface of the main branches. The whole plant is of a dull foxy brown colour.

RHIZOMORPHA Martini
Consists of very fine rounded threads, branching in all directions, mostly serpentine, extremely attenuated and hair-like, matted so as to resemble wool or cotton, or tufted hair; brown in texture, brittle, and woody, bark-like. Mr. Martin found this in large masses in some of the deepest Mines in Derbyshire, and sent it from Buxton. I name it in respectful commemoration of the assiduous Author of " Outlines of the Extraneous Fossils," &c.
