^*Length of the leaf primordium when the apex was placed in culture; the P0 to P-6 primordia were invisible at this time. 

^† Number of leaves with the indicated identity. n = 19, except in the case of leaves 8 and 9, where some leaves became necrotic before they could be scored. Rejuv., rejuvenated adult leaf, with juvenile tissue at the base of the leaf blade and adult tissue at the tip of the blade; Juvenile, completely juvenile leaf; 2nd trans., juvenile tissue at the tip of the leaf blade, adult tissue at the base; Adult, completely adult leaf; Tassel, tassel produced at the indicated position.
