This remarkable Plant grows either in loosely entangled patches of some inches in diameter, or 
more straggling, when attached to the stems of Sphagnum. 
Roots of two kinds (f. 4) : small radicles, such as are common to almost all the species of 
the genus, consisting of minute, whitish, simple, and pellucid fibres, proceed tolerably 
abundantly from nearly the whole length of the plant : but, among these, at uncertain 
distances, descend radicles of a much larger size, and from two to three lines long, 
. of a whitish color, rather opaque, though I cannot perceive that they have any of the 
cellular texture ; sometimes simple, but more frequently divided by three or four small 
< 
lateral and descending shoots. 
Stems from two to four inches in length, procumbent upon the substance that affords them 
nourishment, and consequently erect with regard to the horizon, when they are attached 
to the upright plants of Sphagnum (f. f. 2. 3), filiform, flexuose, simple, or only 
producing here and there short innovations, which resemble the main stems, and are 
of a yellowish-green color, while that of the principal stems is pale yellow-brown.
