Leaves growing in alternate clusters, each at a small distance from the other, so that 
the surculus is eveiy where visible : these clusters * are composed of two or more, 
frequently three, but occasionally of five, and proceed from every side of the plant, 
particularly near the apices, where they form tufts or pencils (f. 3) ; but, when the 
plant is closely attached to the ground, the under side is bare of leaves, and, in such 
case, those which originate from the other parts of the surculus have a secund appear- 
ance : the whole are erecto-patent, setaceous, straight, scarcely the eighth of a line 
long, of a yellowish-green + color , paler when dry, generally simple, but occasionally 
forked, or even branched (f. f. 5. 5), which is more particularly the case with those 
which form the terminal tufts : all of them are divided throughout their whole 
length with transverse dissepiments, forming joints, which are a little longer than 
they are broad, and perfectly cylindrical ; when diy they are frequently alternately 
contracted, in the same manner as the joints of Conferva capillaris of Roth and 
Conf. diffusa, and the coloring matter either contracts into a dark green globule, in 
the centre of the joint, or is confined to the borders of the dissepiments, at the 
same time that the other parts of the leaf are quite pellucid. 
Of the perichatial leaves (f. 6), the external are similar to those just described, the 
internal nearly ovate, entire at the base and for about a third of their length, thence 
cut into many branched capillary segments of various lengths. 
Male Fructification situated in the axillae of those leaves which are collected into a tuft at 
the extremities of the ramuli (f. 3). 
Anthers (f. 7) exceedingly minute, spherical, of an olive-green color, externally marked 
with reticulations ; within containing a fine powdery mass, which gives the color to 
the otherwise transparent pellicle ; they are supported upon a white, extremely 
delicate and pellucid, cylindrical filament, of nearly the length of the globule. 
Female Fructification terminal. 
Calyx (t. 8) elliptical, inclining to obovate, about a half a line long, plicated, con- 
tracted at the mouth, where it is fringed with short cilia, which are sometimes 
bifid : its color is paler than that of the leaves, and more inclining to yellow ; it is 
somewhat transparent, and its whole substance a tissue of small, oblong, compact 
cellules. 
Calyptra ovate, very thin and delicate, reticulated, nearly white, tipped with a short 
style. Abortive pistilla lineari-lanceolate. 
1 eduncle about a quarter of an inch ' nig, pellucid, white, cellulose. 
Capsule at first ovate, in maturity tting into four equal, lanceolate segments, of a 
dark reddish-brown color, longitupL.lly and transversely furrowed. 
Schmidel says that the leaves are not always regularly clustered, for that an intermediate single one is 
.. ^ t0 ^ ounc * ’ anc * Roth goes farther, and observes of the plant, that, “ variat foliis, licet rarissim^, 
soli tarns. Of these I have seen no instances. 
"h Roth describes 
a variety sent him by Trentepohl of a dark-green color.
