Plant growing in rather small, loosely entangled patches of small extent, and of a brownish- 
green color. 
Stems nearly erect, filiform, flexuose, from half an inch to an inch and a half in length, 
simple, or only once or twice dichotomous, with long undivided branches, upon which 
a short lateral innovation is occasionally here and there produced: they are of a close 
texture, of a brownish color, rigid and brittle when dry. 
Leaves (f. f. 3. 4) about one-fourth of a line long, rather distantly placed, more apart at 
the base of the plant, at the extremity collected into a little cluster, hilarious, horizontal, 
subquadrate,' having the sides inclining to conduplicate, but not strictly so, and so ap- 
pressed in their lower part to the stem, that it is almost entirely concealed; the 
upper ones are divided into two equal, rather acute lobes,- but, in proportion as they 
recede from the apex, they become more unequal and acute, and the lower ones of 
all (f. 4), bear no small resemblance to the leaves of that family to which J. nemorosa 
and its congeners belong : here and there a leaf may be found having three lobes or 
segments (f. 5), but such is probably the effect of accident. Upon the innovations.
