A Contribution to the embryology ofAlangium Lamarckii Thw. with a discussion of the systematic position of the family alangiaceæ

  • Published:
Proceedings / Indian Academy of Sciences

Summary

The embryology ofAlangium Lamarckii Thw. has been studied. A cross-section of the anther shows an epidermis, the endothecium, a single middle layer and the tapetum. The haploid number of chromosomes is eight. There is a single anatropous ovule with one integument. The development of the embryo-sac conforms to the Normal type and an epithelial layer is formed from the inner epidermis of the integument. Fertilization is porogamous and the endosperm nuclear. It is concluded that the genusAlangium should be placed in a separate family, the Alangiaceæ, under the order Umbellifloræ.
