The embryogeny of Paeonia tenuifolia (Paeoniaceae)
The embryogeny of Paeonia tenuifolia is described. It is essentially similar to that found in other species of the genus. Following division of the zygotic nucleus, a massive coenocytic proembryo is produced. The endosperm is of the nuclear type in its early stage. The new data do not suppor! the contention that in P. _albiflora, P. delavayi, and P. suffruticosa the coenocyte is a suspensor.
