Loganiaceæ

Loganiaceæ, a natural order of corollifloral exogens, consisting of trees, shrubs, and herbaceous plants, with opposite entire leaves, and usually with stipules, which adhere to the footstalks, or form sheaths. A few species of this order occur in Australia and in the temperate parts of North America; the rest are all tropical or subtropical. No natural order of plants is more strongly characterised by poisonous properties. It includes the genus Strychnos (q.v.; and see NUX VOMICA) and the Curari Poison (q.v.). See also SPIGELIA.
