A, young proembryo; B, later stage, showing differentiation into embryo (» and suspensor (s); x 104.—After ' spherical embryo of hundreds of cells and with no suspen- sor ; while in Nymphaea Conard 81 finds the same type, but associated with it is a suspensor consisting of a row of three to five cells. In Hecheria (Piperaceae) Johnson86 has described the early stage of the embryo as a globular mass composed of several hundred cells undifferentiated except for a rudimentary suspensor; and in Cynomorium (Balanophora- ceae) Juel03 describes the embryo as a small spherical mass of cells with no suspensor and no differentiation into body regions. In Barringtonia Vriesei, one of the Myrtaceae, Treub2T has described a broad mass of tissue almost filling the micropy- lar end of the embryo-sac. At first the mass is homogeneous,.
