The main difference between the species is that the former is heterostylous and the latter homostylous.
In all species, flowers have whitish tubular corollas and are typically heterostylous. The fruits are fleshy two-seeded drupes, whose shape varies among species between ovoid and spherical.
Buckwheat flowers are incomplete (lacking a corolla), perfect, and heterostylous (Stevens, 1912b; Mahony, 1935; Morris, 1952).
These mating system studies usually endeavor to estimate frequencies of selfing and outcrossing (reviewed in Schemske and Lande 1985, Barrett and Eckert 1990, Brown, 1990), but can also include other categories (e.g., intermorph mating in heterostylous species - Barrett et al.
First, from observations in other heterostylous groups, it has been postulated that the breakdown of distyly to homostyly has a simple genetic basis, being brought about by recombination in the distyly locus or by changes at modifier loci (Lewis and Jones 1992).
