Description and Ethnobotany

Growth Form A liana, woody twining vine, climbing up to around 10 m height, with 1.8 m spread. 
Foliage Leaves compound, each composed of 7-13 leathery leaflets; blades ovate-elliptical, oblong, sometimes narrowly lanceolate, base rounded or cuneate, apex acuminate or retuse; each leaftlet measures at about 3 x 1 cm to 6 x 4 cm; texture smooth papery.
Stems Stem thick, many branched; young woody stems have rather attractive, reddish brown bark, pubescent then glabrescent at maturity. 
Flowers Flowers pea-like, bluish-purple petals with bright yellow in the centre, weakly scented like camphor or cedar, with reproductive parts enclosed within the lower petal and visited by ants; large panicles or racemes, 15-20cm across, usually hidden amongst the dense foliage, pendulous, panicles axillary or terminal near the branchlets apex.
Fruits Fruits are velvety, elongated explosive pods, blacken when dry; contain black oblong seeds.
Similar Very similar-looking to Callerya taiwanensis (syn. Millettia taiwanensis), which has a more shrubby habit and is less heat-tolerant.
Taxonomy Despite its common name, plant is not related to the Chinese Wisteria (Wisteria sinensis), a larger and more aggressive climber found in temperate climates. 
Cultivation Ideal as a neat, fine-textured cover for trellises, arbors and fences, where ornamental flowers provide an added surprise of mothball-like scent when closely sniffed. Also occasionally cutlivated as bonsai. Prefers fertile, loose, well-drained soils. Avoid using nitrogen-rich fertilizers to promote better flowering. Remove spent flowers to encourage faster re-blooming.
Etymology Genus epithet 'Callerya' named in honour of 19th century French missionary Joseph Callery, who travelled and collected botanical specimens in China.  Species epithet 'reticulata' means 'netted', a reference to the plant's pinnate leaf venation.
Ethnobotanical Uses Food (Herb and Spice)
[Others]: Commonly known as 鸡血藤 (Ji Xue Teng, literally 'Chicken Blood Stem') in Chinese folk medicine, due to the reddish resin contained within the woody stems. Traditionally used in herbal decoctions to treat blood, menstrual and circulation-related disorders. Also has anti-inflammatory properties, and used to relieve autoimmune diseases like rheumatoid arthritis.
