Afgekia is a small genus of large perennial climbing shrubs native to Thailand in Asia, belonging to the family Fabaceae. [2] They are reminiscent of the related genus Wisteria . [3]
The two species of Afgekia are scrambling climbers, reaching 10–20 m (33–66 ft) high. The mature stems are brown. The leaves are evergreen and generally have 8–16 paired leaflets plus a terminal leaflet. The leaflets are 3–14 cm (1.2–5.5 in) long by 1–7 cm (0.4–2.8 in) wide. The erect inflorescence is a leafy raceme, 30–70 cm (12–28 in) long. The individual flowers are 23–25 mm (0.9–1.0 in) long and have the general shape of members of the subfamily Faboideae. The standard petal is 15–28 mm (0.6–1.1 in) long by 20–25 mm (0.8–1.0 in) wide, cream in colour with pale pink to purple markings and a pale or dark yellow or greenish nectar guide. The deep pink or purple wing petals are more or less equal in length to the keel at 20–25 mm (0.8–1.0 in) long by 5–7 mm (0.2–0.3 in) wide, with short basal claws. The white keel petals are 23–26 mm (0.9–1.0 in) long by 7–15 mm (0.3–0.6 in) wide. Nine of the stamens are fused together, the other is free; all curve upwards at the apex. The inflated seed pods are 6–15 cm (2.4–5.9 in) long by 3–4 cm (1.2–1.6 in) wide, splitting when ripe to release the 2 or 3 seeds. [4]
The genus Afgekia was established by William Grant Craib in 1927, [1] initially with one species, Afgekia sericea . [5] The genus name commemorates Arthur Francis George Kerr, [1] being formed from his initials. Kerr was an Irish physician and pioneering botanist in Thailand in the early twentieth century. [6] The type specimen of Afgekia sericea was collected by Kerr's Thai associate Anuwat. [4]
A 2019 molecular phylogenetic study showed that one of the species then placed in Afgekia (A. filipes, now Padbruggea filipes ) did not belong in the genus, but that the remaining two species formed a well separated clade, sister to Kanburia , in turn forming a larger clade with Callerya , Serawaia and Whitfordiodendron . Morphological characters that distinguish Afgekia from other genera include two rather than one pair of callosities on the standard petal and the longest stipules and floral bracts in the tribe Wisterieae.

As of January 2023 [update] , Plants of the World Online accepted two species: [2]
Callerya is a genus of flowering plants in the legume family, Fabaceae. It belongs to the subfamily Faboideae, tribe Wisterieae. It includes 12 species native to the eastern Himalayas, Indochina, southern China and Taiwan, and Peninsular Malaysia. Its species are climbers, generally reaching up to about 1 m (3 ft) tall. The genus has a somewhat complicated taxonomic history; its circumscription was substantially revised in 2019.
Endosamara is a monotypic genus of flowering plants in the legume family Fabaceae, tribe Wisterieae. Its only species is Endosamara racemosa, a liana found from South India through Indo-China to the Philippines.
Sarcodum is a genus of flowering plants in the legume family, Fabaceae. It belongs to the subfamily Faboideae, tribe Wisterieae. Its three species are twining vines growing over shrubs, and are native from southeast mainland China to the Solomon Islands.
Austrocallerya megasperma, one of several species commonly known as native wisteria, is a species of flowering plant in the family Fabaceae and is endemic to eastern Australia. It is a woody climber with pinnate leaves and racemes of purple, pea-like flowers.
Padbruggea is a genus of flowering plants in the family Fabaceae. Its native range stretches from southern China to western Malesia.
Whitfordiodendron is a genus of flowering plants in the legume family, of Fabaceae. It belongs to the subfamily Faboideae.
Adinobotrys is a genus of flowering plant in the family Fabaceae, native to from Indo-China to western Malesia. The genus was first described in 1911.
Wisteriopsis is a genus of flowering plants belonging to the family Fabaceae. Its native range is China to Indo-China and Temperate Eastern Asia. Wisteriopsis species are twining woody vines, generally resembling species of Wisteria. The genus was established in 2019 as a result of a molecular phylogenetic study, and includes species formerly placed in Millettia or Callerya.
Austrocallerya is a genus of flowering plants belonging to the subfamily Faboideae in the family Fabaceae. They are robust, twining woody vines.
Nanhaia is a genus of flowering plants belonging to the family Fabaceae. Its native range is Southern China to Northern Vietnam.
Wisterieae is a tribe of flowering plants in the bean family Fabaceae. The tribe was first described in 1994 for the sole genus Wisteria, but was greatly expanded in 2019 to include 13 genera, six of which were new. Five had previously been placed in the tribe Millettieae. Members of the tribe are climbers of various kinds. Some, like Wisteria, are cultivated for their flowers.
Sigmoidala is a monotypic genus of flowering plants in the family Fabaceae, first established in 2019. Its only species is Sigmoidala kityana, native to Myanmar, northern Thailand and Laos. It was first described by William Grant Craib in 1927 as Millettia kityana.
Kanburia is a genus of flowering plant in the family Fabaceae, native to Thailand. The genus was established in 2019. Kanburia species are twining woody vines.
Serawaia is a monotypic genus of flowering plants in the family Fabaceae, first established in 2019. Its only species is Serawaia strobilifera, endemic to Borneo. The species was first described in 1994 as Callerya strobilifera.
Wisteriopsis japonica is a species of flowering plant in the family Fabaceae, native to Japan, Korea, and the Ryukyu Islands. It was first described in 1839 as Wisteria japonica.
Villosocallerya bonatiana is a species of flowering plant in the family Fabaceae, native to south-central and southeastern mainland China, Laos and Vietnam. It is the sole species in genus Villosocallerya. The species was first described in 1910 as Millettia bonatiana.
Austrocallerya pilipes, synonym Callerya pilipes, is a species of flowering plant in the family Fabaceae, endemic to Queensland, Australia. It is a robust twining vine, climbing up trees and shrubs. It is known as the northern wistaria.
Austrocallerya australis, commonly known as native wisteria, blunt wisteria or Samson's sinew in Australia, is a species of flowering plant in the family Fabaceae, native to north-eastern Australia, New Guinea and some Pacific Islands. It is a tall, woody climber with pinnate leaves, the leaflets oblong, elliptic or egg-shaped, and panicles of purple, pea-like flowers.
Swainsona sericea commonly known as silky Swainson-pea or silky pea, is a flowering plant in the family Fabaceae. It is a small perennial with greyish-green leaves, purple flowers and grows in New South Wales, Victoria and South Australia.
Senna sericea is a species of flowering plant in the family Fabaceae and is endemic to inland north-western Australia. It is an erect shrub with pinnate leaves, with one or two pairs of egg-shaped leaflets, and yellow flowers arranged in groups of four to twelve, with ten fertile stamens in each flower.
