Description and Ethnobotany

Growth Form Evergreen leguminous vine with bushy growth and slender woody stems at base, able to reach 10m with support.
Foliage Leaves odd-pinnately compound, with opposite oblong leaflets. Leaflets elliptical (6.5cm by 2.5 cm), soft, densely pubescent on both surfaces and along margins, appearing silvery-green on top and pale green below. Young leaflets densely furry, appearing silver-white before unfolding, produced on tomentose twining stems.
Flowers Papilionoid (pea-like), with 5 furry-pubescent pink-white petals -- 1 light pink and white upper-petal ("standard") with pink-yellow nectar guide, 2 dark to purplish-pink lateral-petals ("wings") that form a cap over 2 white lower-petals ("keel"), which in turn enclose the reproductive parts within a boat-like structure. Inflorescences raceme, long and many floreted, upper portion pink, typically produced near top of plant. Florets open gradually from base to tip of inforescence over some 2 months. Each floret opens and becomes receptive from 4am, but lasts only for 24 hours. Flowering occurs from mid-May to end October during rainy season in native range, but plant blooms almost year-round outside of natural habitat, as observed in urban Bangkok and Singapore. Florets pollinated by bees, chiefly Megachile velutina (Leafcutter Bee), which visit the plant for nectar, pollen and leaves (used as nesting material). Species is thought to be cross-pollinating and self-incompatible.
Fruits Pubescent seedpods, produced in clustered infructescences, ripening to brown with beige hairs. Species rarely sets fruits (< 0.2% at native sites). Fruiting not observed in Singapore.
Habitat Climbing on trees near edges of lowland and hill dry dipterocarp forests. Discovered in northeast Thailand in 1928 and thought to be endemic to Thailand, until it was also collected from Vietnam in 2000. Species considered relatively rare, currently threatened by habitat fragmentation, low population densities and very limited fruit production.
Similar Resembles the closely-allied species Afgekia mahidoliae (Kan Phai Mahidol), whose natural range of limestone deciduous forests in western Thailand lies 320km away and across the breath of the Chao Phraya River. Differentiated by its inflorescences of purple-white florets, as well as its larger broad-oval leaflets (7..5cm by 4.3 cm) that are pale green and less hirsute below.
Cultivation Fuss-free plant. Provide regular moisture. Can be trained as a potted plant by twining the stems around stakes. Propagate by seeds (if available). Cuttings reported to be difficult to strike.
Etymology Genus epithet "Afgekia" derived from the name initials of Irish medical doctor and plant-collector Arthur Francis George Kerr (1877-1942), who worked from 1925-1931 as a distinguished taxonomist for the Flora of Thailand Project. Species epithet “sericea” means "silky", a reference to the pubescent nature of the plant. Vernacular name "Kan Phai" means "protecting from threat" in Thai, and is represented as a captivating benovelent vine in Thai religious sacraments.
Ethnobotanical Uses Food (Herb and Spice)
[Others]: Roots used to treat chicken pox and throat problems like follicular pharyngitis.
