Studies in the embryology of the Leguminosae

II. Embryo development inAeschynomene aspera Linn.

  • Published:
Proceedings / Indian Academy of Sciences

Summary

Fertilization is porogamous. The embryogeny falls under Group 1 of Series A of Grand Period I according Souèges’ system but the organization of quadrant fromca differs from that ofCoronilla minima which is described as the type under this category. The embryo development follows the Onagrad type but does not conform to any of the known variations under this type in the system of Johansen. Therefore, a new variation to be called as Aeschynomene variation under the Onagrad type, is proposed to accommodate the present species.

The endosperm is first nuclear and then cellular. Ultimately, it is completely absorbed by the developing embryo. The mature seed is thus non-endospermous. The mature testa consists of all the layers of the outer integument and one or two layers of the inner integument.
