This grows parasitic on trees in the form of a large irregular 

 tuber, fastening itself to them by fibrous roots, and throw- 

 ing out several branches above. The tuber is generally 

 inhabited by ants, and hollowed by them into numerous 

 winding passages, which frequently extend a good way along 

 the branches also, giving them the appearance of being fis- 

 tular. Leaves opposite, short-petioled, elliptic-obovate, 

 nearly obtuse, acute at the base, very entire, very smooth, 

 thick, with the midrib flattened, and a few inconspicuous 

 nerves. Stipules interpetiolar, linear. Flowers axillary, ses- 

 sile, generally aggregated on a double gemmaceous knob. 

 Calyx superior, very short, entire. Corolla white, tubular ; 

 limb four-cleft ; faux villous. Stamens alternate with the seg- 

 ments of the corolla; filaments scarce any. Ovary crowned 

 with a prominent umbilicate disk, disporous. Style longer 

 than the tube. Stigma of two re volute linear thick lobes. 

 Berry of a semipellucid reddish-yellow colour, ovate-oblong, 

 two- seeded. Seeds oblong, contained in a tough integument, 

 with the embryo in the axis of the albumen.
