Endosperm with Micropylar and Chalazal Haustoria
Some plants develop haustoria from both micropylar and chalazal ends of endosperm. In Nemophila aggressive haustoria arise from micropylar and chalazal ends. The chalazal haustorium sometimes gives out a prominent lateral branch which grows towards the funiculus so as to come in direct contact with the starchy tissue of the placenta.
In Melampyrum lineare, the micropylar haustorium comprises a single cell with many tubular processes which enlarge considerably and invade the tissue of the integument and funiculus. The chalazal haustorium is short and confined to the nucellar tissue only. In Klugia notoniana the chalazal haustorium grows laterally and terminally, consuming the sub-epidermal cells of the integument. The micropylar haustorium starts functioning after the activity of- the chalazal haustorium declines.
