This is a shrubby creeping plant, but net properly parasitical ; at first it is radicant, 

 Kke some ferns, whence Sloane has given a figure of -a young pia:it among his ferns.

 some tree, to the top of which it frequently runs,, at length dividing.into several sub- 

 divided, loose^ pendulous, branches, commonly terminated by Howering umbels - 

 The leaves of a young-rooting plant are roundish, sub-sessile, slightly emarginate, 

 with an eniire margin and giaiiJular dots. Leaves of the branches distich, alternate, 

 on sh(jrt petioles, ovate-lanceolate, of a thick consistence, d ci luou<, smooth Um-
