Only the outer integument forms the seed coat. The inner integument disintegrates during seed development. The epidermis of outer integument differentiates into the macrosclereid layer and the hypodermis into the osteosclereid layer. The tracheid-bar is present below the well defined and complex hilar region. The seed coat surface shows deposition of cutin in the form of rope-like upwellings which make it impermeable to water. The macrosclereid cells are packed very tightly and this compactness may also be responsible for the impermeability.
