Cassia lanceolata.

Characters. - Lanceolate or obovate leaflets, about an inch long, unequally oblique at the base, brittle, greyish-green, of a faint peculiar odour, and mucilaginous sweetish taste.

Parts employed. - The leaves, as imported from Alexandria.

Preparation. - Tincture (proof spirit).
