SCHOMBURGk's GUIANA PLANTS. 243 



rium suhaquantes.—Oi this handsome plant I have but one 

 fruit, which is above five inches long, and an inch and a half 

 thick, tapering a little towards the extremity. The seeds 

 are very numerous (above a hundred), an inch and a quarter 

 long, of a brown colour, but apparently in my specimen not 

 quite ripe, as I have not succeeded in finding a single per- 

 fect embryo in above a dozen that I have opened.

 corollsB tubo inflato apice constricto limbi laciniis vix longi- 

 ore. — Folia 6 — 10-pollicaria. Cymae bis dichotoniie. Flores 

 albi, cymae in quoque ramo 6 — 8, vel interdum numerosiores. 

 Corollge tubus 7 — 8 lin. longus. — AfBnis T. undulaCcB et forte

 flowers according to Schoniburo;k are white and odoriferous.
