cal Items, which twine round any neighbouring fup- 
port, and reach fometirnes to the height of thir- 
ty feet or more, fending off many long twining 
branches. The leaves are large, entire, and heart- 
fhaped, of eight inches or more in length, and as 
much in breadth, (landing upon thick ftrong foot- 
ftalks. The flowers come out fmgly, or fometirnes 
two together upon pretty long foot-flalks, which are 
either terminal, or arife beneath the divifions of the 
branches, each having a bra&ea or floral leaf em- 
bracing it near its bafe ; they confifl of a long tube 
which is very crooked and bellied towards the bafe, 
but narrower towards the extremity, and furnifhed 
with a border which at firfi appears three lobed and 
triangular (in form of a cock'd hat,) but after be- 
comes fpreading, plain and roundifh, and together 
with the interior extremity of the tube, is finely va- 
riegated with fpots or flreaks. The Capfules or 
Seed-veffels are cylindrical fix-fided, of three or 
four inches in length and near one in diameter, 
opening with fix Mures, and having fix cells, filled 
with heart-fhaped compreffed feeds, with a falfe one 
between each. This from its twining flems and 
large leaves affords a fine fhady covering for an ar- 
bour. 
The roots have an aromatic penetrating favour, 
and are fuppofed to be equal in medical virtues to 
the finall Virginian Snake-root.
