Buds and leaves | verticillate by 2 or 3, slightly brought forward * | opposite* |
Leaves | 30-40 cm | 40-50 cm |

* a mnemonic device to remember the difference: in "catalpa", there is 3 " a ", and it makes think of leaves of whorled by 3, while in "Paulownia", there is only 2 " a ", and its leaves are by 2 (opposite)!
