KEY TO THE GENERA. 



A. Carpels 5-2 (or 12-1) verticillate, either on a special receptacle or immersed in the persisting 



axis, each with 2-00 seeds. Filaments from a broad basis, smaller upwards. Sepals often

Az. Carpels 5-2, connate with the inner wall of the hollow, floral axis, and with each other, 



becoming in fruit a fleshy pome. 



b. Carpels several seeded, the seeds in two series. 2. Cydonia, p. 468.
