Helobial type of endosperm:
→ It is an intermediate between nuclear and cellular type of endosperm.
→ First division of primary endosperm nucleus is followed by (division of cytoplasm) wall formation.
→ The wall formation results in the central cell being divided into a large micropylar and a small chalazal chamber.
→ In both the chambers the development occurs as seen in nuclear type.
→ This type is generally seen in Helobiae series of monocots, hence the name ‘Helobial Endosperm’.
