Gen info
- Dendrolobium is a genus of flowering plants in the legume family, Fabaceae. It includes 21 species of mostly trees and shrub, and rarely, herbs.
- Etymology: The genus name Dendrolobium derives from Greek words Dendron, meaning tree or wood, and lobos, meaning pods, together "woody pods". The specific epithet umbellatum derives from Latin for umbels, referring to the flower cluster arrangement in which stalks of nearly equal length spring from a common center and form a flat or curved surface.

Botany
Dwarf shrubs to shrubs or small trees, to 3 m tall. Young shoots terete, densely appressed sericeous. Leaves 3-foliolate; petiole 2-5 cm; terminal leaflet blade elliptic or ovate to orbic­ular or broadly ovate, 5-14(-17) × 3-7(-8.5) cm, lateral leaflets slightly smaller, abaxially appressed long hairy, adaxially gla­brescent, lateral veins 7-12 on each side of midvein, reaching margin. Umbels often 10-20-flowered. Pedicel 3-7 mm at an­thesis, 5-12 mm in fruit. Calyx 4-5 mm, upper lobe 2-toothed at apex. Corolla white; standard broadly obovate or elliptic, 1-1.3 cm × 6-10 mm, clawed; wings narrowly elliptic, 1.1-1.2 cm × 1-2 mm, clawed; keel broader than wings, 1.1-1.2 cm × 3-5 mm, clawed. Stamens ca. 1 cm. Pistil to 1.5 cm; ovary seri­ceous; style ca. 1.2 cm, glabrous. Legume narrowly oblong, 2-3.5 × 0.4-0.6 cm, (3-)8-jointed; articles broadly elliptic or ob­long. Seed elliptic or broadly elliptic, ca. 4 × 3 mm.
(Flora of China)

Growth form: A tree up to 6 m tall. Foliage: Pinnate, stalked leaves have leaflets that are elliptic to broadly egg-shaped, the underside of which are covered with fine hairs. The terminal leaflet is 5–17 by 2.5–8.5 cm, and the lateral leaflets 3–11 by 1.5–6 cm. Flowers: Flowering cluster consists of 10–20, 13 mm-long, white flowers. Fruit: Thick, elongated, leathery fruit pods consist of 3–8 segments that are 1-seeded, broadly elliptical-oblong to oblong, and 5–10 by 3.5–5 mm. (Flora & Fauna Web)

• A shrub or small tree up to 3(-6) m tall, branches terete, lenticellate, glabrescent, young parts (4-)6-7-gonous. Leaves 3-foliolate, petiole (1-)2-5(-6) cm long, stipules early caducous, leaflets elliptical to broadly ovate, base obtuse to acute, apex obtuse to acute, continuously appressed-sericeous when young, upper surface glabrescent, lower surface remaining covered with appressed fine hairs, terminal leaflet 5-14(-17) cm × (2.5-)3.5-7(-8.5) cm, lateral leaflets 3-11 cm × 1.5-6 cm. Axillary inflorescence shortly peduncled or long racemose, 10-20-flowered, primary bracts 2-2.5 mm × 1-1.5 mm, early caducous. Calyx 4-5 mm long, corolla white, standard obovate or elliptical, wings narrowly elliptical, keel petals much broader than the wings, androecium 8.5-10 mm long, gynoecium 14-15 mm long, ovary densely appressed-sericeous. Pod sessile or slightly stalked, narrowly oblongoid, 3-5(-8)-jointed, rarely 1-seeded by abortion, glabrescent, both sutures not thickened, upper suture slightly undulate, lower suture undulate and constricted between the seeds, articles in outline broadly elliptical-oblong to oblong, (5-)7-8(-10) mm × 3.5-5 mm.

Constituents
- Proximate analysis of leaves of D. umbellatum revealed dry matter nutrient content of 29.66%, organic matter 92.62%, crude fiber 13.37%, and crude protein 17.98%. Comparatively, dry matter and organic matter content are low, 60.06% and 59.13% respectively; crude protein and fiber content are lower 17.93% to 19.44%. (Comparatively lower crude protein and fiber content may be attributable to growing in a coastal area with low nutrient content.)

Properties
- Studies have suggested antibacterial properties.

Parts used
Leaves, shoots, flowers.

Uses

Edibility
- Leaves are edible: young leaves eaten as vegetable or used as seasoning; sometimes eaten raw in the Moluccas and Malaysia.
Folkloric
- No reported folkloric medicinal use in the Philippines.
- In Papua New Guinea, crushed leaves and shoots use to massage an enlarged spleen caused by malaria. Decoction of leaves drunk as a general tonic. Solution used to bathe the body to prevent a slight chill developing into a fever. (3)
- In the Moluccas, plant used as an astringent; young leaves used as ingredient of post-partum medicine used after childbirth. (3)
- In Fiji, leaves used for treatment of scaly skin. (3)
- In Taiwan, decoction of flowers used for treatment of gonorrhea and irregular menstruation. (3)
- In
Bangladesh, used for treatment of enlarged spleen, fever, headache and malaria. (5)
- In India, fresh tubers taken orally as childbirth medicine, treatment of gonorrhea, scaly skin, irregular menses, and scaly skin.
Others

- Fodder: In India, plant used as fodder; particularly favored by horses. (3)
- Wood: Used as fuel. In construction, used for posts and small posts.
- Agroforestry: Suitable for protection of planting and erosion control on beaches and sand dunes. (4)

Studies
Antibacterial / Leaves:
Study evaluated fresh, aqueous and methanol extracts of leaves of D. umbellatum (horse bush) and Psophocarpus tetragonolobus (winged beans),and Cassia alata (candle bush) for individual and synergistic activities against Gram-positive Staphylococcus aureus (ATCC 25923) and Gram-negative E. coli (ATCC 25922) using agar well diffusion method. The ME of horse bush showed 12.0 mm zone of inhibition against S. aureus. In synergistic studies, all combinations showed inhibition of S. aureus. None of the extracts showed inhibition of E. coli, which may be due to the presence of harder cell wall structure in E. coli compared to S. aureus. (7)

The compilation now numbers over 1,750 medicinal plants. While I believe there are hundreds more that can be added to the collection, they are becoming more difficult to find. If you have a plant to suggest for inclusion, native or introduced, please email the info: scientific name (most helpful), local plant name (if known), any known folkloric medicinal use, and, if possible, a photo. Your help will be greatly appreciated.
