Micrampelis. Micrampelis fabacea (Naud.) Greene. (Megarrhiza californica Torr., Echinocystis fabacea Naud.) Man Foot. Big Root. Gerba marra. (Fam. Cucurbitaceae.)—J. P. Heaney has obtained a substance from. this root of resinous character which he calls megarrhizitin, and another which he believes to be a glucoside and calls megarrhizin. It is said to be actively cathartic. (A. J. P., 1876, 451.) A second glucoside was obtained by W. M. Young (A. J. P., 1883, 195), to which the name of megarrhin was given. It resembles saponin, and possesses the property of dilating the pupil. Young also found two resins, one soluble in alcohol and the other soluble in ether.
