Rhynchosia acuminatifolia, a
perennial vine, occurs in fields and mountains. It resembles another
species, R.
volubillis, but
there are some morphological differences between them. With Rhynchosia
acuminatifolia, leaflets
are large and thin, and tips abruptly become narrow to get pointed.
Also, the width of the leaflet's lower halves is broadest, while in R.
volubillis, the
upper halves are widest. Bloom time: July-September.
