of the nearly sessile leaves, gives it the appearance of
a trifoliate plant, the lower pair representing stipulæ.
Though Michaux's description answers very well in
any other respect, I was led to doubt by his not men-

most striking characters. 3. T. gracilis, humifusa, pubescens ; foliolis (13—15) ob- hispidula.

Nole.-In addition to the observations under Psoralea

esculenta, p. 475. it may be interesting to state, that A. B. Lambert, Esq. raised in the summer of 1812 a number of plants, the seeds of which were taken out of a specimen collected in the year 1805 by M. Lewis, Esq. Also, that this highly interesting plant is now growing at Messrs. Frasers, Sloane Square.
