If no rank is listed, the taxon is considered an unranked clade in modern classifications. Ranks may be repeated or presented in the wrong order because authors working on different parts of the classification may disagree about how to rank taxa.

S. R. Manchester and W. J. Kress 1993Seed anatropous, subfusiform-ellipsoidal, circular to subangular in transverse section, base rounded, apex truncate; length of complete seed 10.0-12.0, X=10.8 mm (SD=0.96, N=4), width 5.3-7.2, X=5.8 mm (SD=0.43, N=15), with a wide hilar depression, and an operculum (micropylar plug) about 1.2 mm diameter; hilar rim ca. 1 mm high; outer surface of seed smooth to finely striate longitudinally; seed coat of two layers, each 200-250 micrometers thick and composed of longitudinal fibers, the inner layer diverging from the outer seed coat near the base and apex of the seed, delimiting a chalazal mass at one end, a micropylar collar at the other, and a central barrel-shaped embryo/endosperm chamber; embryo small, 2.5 mm long, straight and bulbous, ascending from the channel delimited by the micropylar collar into the central chamber. Length of central chamber (from specimens missing chalazal mass and hilar rim) 4.3-8.5, X=6.0 mm (SD=0.84, N=47), width 5.3-7.2, X=5.8 mm (SD=0.43, N=15).
