(Structural aspects of the zygotic embryogenesis of Acca sellowiana (O. Berg) Burret (Myrtaceae)). Acca sellowiana has anatropous, bitegmic and crassinucellate ovules. The outer and inner integuments are double-layered ...

This is the first embryological report of the Grewioideae subfamily, which is meant to contribute to the characterisation of the genera Corchorus, Luehea and Triumfetta. Ovule and female gametophyte development in C. ...

Ovule and female gametophyte development in C. argutus, L. divaricata and T. semitriloba was analyzed. The ovules of all species are anatropous, bitegmic and crassinucellate mixed type. The micropyle of the studied species ...
