Impatiens eramosa Tutcher

This species has very short pedunculate inflorescences, pedicels bracteate at the base, and distal lobes of lateral united petals connate or adnate into a lamella. These characters seem to indicate a group in the genus including also Impatiens hainanensis, I. morsei, I. musyana, and I. polyneura.
