ramerous, octandrous. Hard clayey soil. April, June. — We 
have this plant in cultivation. The foliage is nearly as sensi-

June, and frequently flowering again in September. 
51. Acacta Farnesiana, Willd.; Benth. Nearly the only 
shrub on Galveston Island, where it attains the height of 6 or 
7 feet, and forms considerable thickets. Its odorous flowers 
are produced in April or May. Certainly indigenous to Texas,
