the stem. It is difficult by characters to separate this from 
Jung. complanata, L. although it differs widely in habit. 
The present is smaller in all its parts, while the stem itself 
is thicker in proportion to the entire width of the shoots, the 
leaves are more round, the lower lobe, lying parallel with the — 
stem, is longer, and by a round process embraces the stem, 
the cells of theleaves are more minute.

Creeping, scattered, pale olive-brown. Stems arcs 
half an inch long, branches very slender, their leaves minute: 
Leaves cup-shaped, with an obtuse angle at the point most 
distant from the stem. The lobule has a tumid base, whilst 
its top lies flat on the inner part of the leaf and has a single 
angle pointing outwards. ‘The perigonia occur in the course - 
of the shoots, and are remarkably long and large in propor- - 
tion to the size of the stems. The present is the minutest 
of the Radule of Nees yet observed, and is readily distin- - 
guished by its peculiar perigonia.
