Strychnos toxifera.

Botanical name:

This is another species of the Strychnos, and the one which yields the basis of the celebrated poison of Guyana, known as Woorari, Ourari, or Urari, which is said to "produce paralysis with convulsive movements, and death from apparently suspended respiration."—Pereira.

There are sundry other species of the Strychnos named by systematic writers, most of which are poisonous, but as none of these are used for medicinal purposes, it is unnecessary to devote more space to their consideration.
