Wilmot-Dear, C.M. (2009). Notes on Mucuna (Leguminosae: Phaseoleae) in Thailand. Kew Bulletin 64: 579. https://doi.org/10.1007/s12225-009-9130-6

Note
Eight new collections of Mucuna thailandica (previously known from only two, flowering specimens) provided three fruiting specimens and clarified flowering and vegetative differences between this species and M. macrocarpa Wall. M. thailandica is easily distinguished in flower but it is almost identical to M. macrocarpa in fruit and not always distinct vegetatively.
Conservation
Apparently rare, known so far only from the type locality, but its habitat (montane forest 1000 – 2400 m.) is not currently endangered. Therefore Least Concern (LC).
Ecology
Montane forest 1000 – 2400 m.
Morphology Reproductive morphology Flowers Corolla
All petals greenish white without ciliate apex; wings 7 – 7.5 cm long, keel 7.5 – 8.5 cm long
Morphology Leaves Leaflets
Leaflets always soon glabrescent, terminal leaflet relatively wider, laterals less markedly asymmetrical, length/width ratio of terminal leaflet and ratio of abaxial to adaxial halves of laterals 1.5 – 1.75:1; fruit (but note that only 3 collections seen) longer, 45 – 60 cm, not or only slightly constricted between seeds
