The genus Kaisupeea is established for Boea herbacea, a species long recognised as being out of place in Boea, and two new species closely allied to it. These plants produce annual flowering stems whose basal leaves may be represented by broad foliaceous cataphylls. Kaisupeea herbacea and K. cyanea have spirally twisted fruit-valves, but those of K. orthocarpa are straight. Kaisupeea ranges from Moulmein in Burma [Mawlamyne in Myanmnar] eastwards across Thailand to Bassac on the Mekong river in lower Laos and south to the neighbourhood of Satun on the south coast of Thailand just north of the Malaysian border.
