Larch species have been induced to form embryoids both from both haploid and diploid expiants. The developmental steps in embryogenesis of diploid expiants of Larix leptolepis, L. decidua, L. occidentalis and L. x eurolepis are outlined and compared with the embryogeny of zygotic embryos. The various terms commonly found in the classical embryological descriptions are discussed in terms of their usefulness in describing events in vivo. A number of tissue culture terms, such as proembryo(id), embryonal suspensor mass, and callus are discussed as well. This comparative embryological study is extended to haploid embryoid development, which is initially different from both somatic and zygotic embryogenesis.
