Order Lii
SIMARUBACEÆ.
Thirteen plants, found in equinoctial America, constitute this order. They are trees or shrubs, with an intensely bitter bark, a milky juice, and pinnated pinnated leaves. The Quassia is well known as the most pure and intense bitter hitherto discovered ; the same property exists, in a milder degree, in the rest of the order. Quássia amára is a very ornamental plant, but rare, at present, in collections. 1002 Quássia W.
