SURCULI of various lengths, from one to two inches 
flat, irregularly branched, creeping on the 
bark of the trees in large patches. 
LEAVES of a pale yellow-green colour, clofely imbri- 
cated, alternate, round, fomewhat tranfparent 
flat, above entirely covering the mid- rib of the 
furculus, beneath fmall round fcales adhere to 
the mid-nb, the whole plant, when frelh, is 
foft to the touch, moiftened with water it 
grows flaccid. At the extremities, and here 
and there at the origin of the branches, pro- 
ceed flat Jheaths appearing truncated or cut off 
at top, from whence proceed fhort feta; or pe- 
duncles about a line in length, very {lender 
and terminated by fmall black heads fplittinsr
