Gen. Cuar. Frond filiform, solid, much branched, inarticulate, reticulated ; 
the axis composed of concentric layers of oblong, hyaline cells; the 
periphery of several rows of minute, irregular, coloured cellules. 
Fructification of two kinds, on distinct individuals; 1, ovate capsules 
(ceramidia) contaiming a tuft of pear-shaped spores; 2, ¢etraspores 
immersed in swollen ramuli, in a single row. Ruopomea (Ay.)— 
from podeos, red, and pédas, black; because the species usually become 
darker in drying. 
Ruopometa /ycopodioides ; frond divided near the base into several long, 
simple branches, which are densely beset with slender, finely-divided 
branchlets, mixed with the short, rigid, bristle-lke remains of a former

Descr. Root asmall disc. Fronds from four inches to two feet in length, 
about half a line in diameter at base, attenuated upwards, cylindrical, fili- 
form, tufted, either simple, or divided at a short distance from the base 
into several long simple branches, clothed in its winter state with short, rigid, 
simple, or slightly branched, imbricated ramuli, from half an inch to an 
inch in length; in summer throwing out from these and from the main 
stems, numerous, capillary, multifid ramuli, usually from one to two inches in 
length, but occasionally lengthened into branches from six to fourteen inches 
in length, and bearing, at short distances, broad tufts of multifid ramuli 
resembling those usually borne by the main stem. Capsules abundant on 
the summer ramuli, ovate, containing a tuft of pear-shaped seeds. Tetra- 
spores tripartite or cruciate, contained in clustered or racemose, stichidiform
