Studies on samh seeds (Mesembryanthemum forsskalei Hochst) growing in Saudi Arabia, 1: Anatomy of Samh seed.

The seeds of Samh (Mesembryanthemum forsskalei) are 'Ostensibly Campylatropous' as they seem externally anatropous but internally they have a curved embryo and both the seed body and the funicle exchange shapes. The embryo occupies a cylindrical seed body and is surrounded by a thin layer of endosperm; the major part of the endosperm occupies an ovoid bulge resembling a seed body.
