Hab. In most shady woods. Mr. Dickson. — On Holt and Edgefield Heaths, in wet places, 
plentiful. Rev. R. B. Francis. — Abundant upon Moushold Heath, near Norwich, and on 
hedge-banks and heathy places, near Yarmouth. — On the highland mountains of Scot- 
land. — /3 is not uncommon in similar situations with a. 
This minute Plant is found in scattered patches, sometimes covering several inches of surface, 
firmly adhering to the soil by means of the numerous, simple, pellucid, fibrous radicles. 
The Stems, which are usually dark green, though sometimes inclining to deep brown 
or black, vary considerably in their extent, from half a line to five or six times that 
length, and are about the tenth of a line in diameter, throughout cylindrical, simple, 
or here and there producing a lateral shoot. 
Leaves (f. 4, 5) a quarter of a line long, rather closely placed, patent or horizontal, 
(erect in var. /3.) subquadrate, approaching to orbicular, slightly concave, semi- 
amplexicaul at the base, at the extremity deeply emarginate, with an obtuse sinus, 
the segments acute, strait, and equal in size : the color is rather a Jeep green \ the 
reticulation small, and formed by cellules of a roundish figure. 
The perichcetial leaves (f. 6) differ from the rest only in being most frequently tridentate. 
Male Fructification I have not been able to discover. 
Female Fructification terminal, most abundant upon such plants as are going into a state 
of decay.
