Description:Description - Leaves 1.5-7.0 cm long, 1.0-3.0 cm wide, villous-strigose to lanate. Inflorescences terminal panicles, 4.0-8.0 cm long. Flowers in 3-florate cymes (sometimes 1-florate). Fruit 0.8-1.5 cm long.
Discussion:This subspecies is one of the most collected taxa in the genus. Because of the high variability of characters, it has been treated as several species, or at best, as several varieties. I agree with Fromm & Santos (1971) in considering it as only one taxon; it is impossible to separate morphologically the taxa delimited by other authors.The affinities of the species as a whole indicate close relationships with both Trigonia laevis and T. paniculata.Trigonia eriosperma subspecies eriosperma can be separated from T. paniculata by its shorter panicles, the panicles being terminal (vs terminal and axillary in T. paniculata), by its more glabrous stems and flowering branches, by the lack of a white “border” on the margins of the leaves, and by the sparser pubescence of the leaves in general.
