Diagnosis
Fruits/fruitlets indehiscent, with a thin wall and up to about six seeds per carpel, rarely only a single seed. Style lacking. Seeds small, arranged in two rows along the ventral margin, strongly appressed and permanently coherent. Seeds anatropous, bitegmic, and mesotestal-endotestal with thick outer integument (testa) and thin inner integument (tegmen). Exotesta thin. Mesotesta one or two cell layers thick, composed of larger sclerenchyma cells. Endotesta several cell layers thick, composed of small, polygonal, and equiaxial cells with endoreticulate infillings. Seed surface smooth to faintly reticulate or rugulate. Hilum and micropyle close together. Micropyle formed from the inner integument. Micropylar opening in testa wide, transversely oriented. Hilar-micropylar area of adjacent seeds alternating and forming two rows where multiple seeds are present. Ovular vascular bundle continuing beyond the chalaza on the antiraphal side of the seed to the micropyle. Embryo tiny. Endosperm cellular, not-ruminate.
