THE Psoralea pinnata is a very ornamental plant for the conservatory, and certainly deserves a coloured
representation. At present there are only two uncoloured engravings of it extant: one in the Flora
tetrapetala of Rivinus, No.-5.; the other in Hermann's Hortus Lugdunensis, tab. 273. The Psoraleas
are a well marked natural genus, and appear much more characteristic of each other than many of
the Papilonaceous genera.
Our drawing was made from a fine specimen received from the collection of the Hon. W. Irby.
