cylindrical appearance, when moistened, however, they be- 
come patent with their tops recurved. The stipules are 
imbricated, thin, round, broader than long. Calyces flattened 
and compressed beneath, and have two ridges on the upper 
and convex surface besides the lateral wings. 
The present differs from Thysananthus comosus, Lind., 
from Guyana by its smaller size, by the more rounded tops 
of the leaves, by the absence of a decurrent tooth at each 
side to the stipules, which too are broader than long and their 
margins are plane not recurved.

Patches several inches in diameter, olive-coloured as in 
Parmelia olivacea, Ach. Stems about half an inch long; 
branches short, thick, much clustered in the patch. Leaves 
appearing wrinkled when dry from the turning in of the 
anterior margin, their tops discharging colour and becoming 
white and skinny by old age; the lesser lobe tumid, having 
a single tooth near its junction with the upper lobe out- 
wards. Stipules large, widely elliptical, entire, but the 
margin liable to be corroded by insects or by time. 
This is allied to Jung. conferta, Meissner, which, however 
is a smaller plant, with less opaque leaves and whose inferior 
lobe wants the single tooth conspicuous in the present.
