cal ftems, which twine round any neighbouring fup- 

 port, and reach fometimes to the height of thir- 

 ty feet or more, fending off many long twining 

 branches. The leaves are large, entire, and heart- 

 Ihaped, of eight inches or more in length, and as 

 much in breadth, ftanding upon thick ftrong foot- 

 llalks. The flowers come out fingly, or fometimes 

 two together upon pretty long foot-ftalks, v/hich are 

 cither terminal, or arife beneath the divifions of the 

 branches, each having a bradea or floral leaf em- 

 bracing it near its bafe ; they confift 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 firft appears three lobed and 

 triangular (in form of a cockM hat,) but after be- 

 comes fpreading, plain and roundifli, and together 

 with the interior extremity of the tube, is finely va- 

 riegated with fpots or ftreaks. The Capfules or 

 Seed-veffels are cylindrical fix-fided, of three or 

 four inches in length and near one in diameter, 

 opening with fix fiffures, and having fix cells, filled 

 with heart-ftiaped comprefled feeds, with a falfe one 

 between each. This from its twining fl:ems and 

 large leaves affords a fine ftiady covering for an ar- 

 bour. 



The roots have an aromatic penetrating favour, 

 and are fuppofed to be equal in medical virtues to 

 the fmall Virginian Snakc-root.
