Horn. 
Stems nearly two inches long, very slender; shoots pale 
olive-green, sometimes reddish-brown, bending. Leaves 
closely imbricated and adpressed to the stem, tumid, hence 
the shoots to the naked eye resemble those of certain Ptero- 
gonia ; with two, three or four erect branches issuing often 
from the same point, the tegument of the stem has large 
whitish cellules. Leaves with entire segments, which 
have an irregular outline. No stipules present. This 
species has an affinity to Jung. concinnata, (Lightf.) It is, 
however, by no means tufted, the shoots are more slender 
and flexible, the leaves have lanceolate segments and the 
stems are cellulose in a peculiar manner. |
