Origin and geographic distribution
Sarcophrynium brachystachyum is distributed from Senegal to the Central African Republic and DR Congo.
The leaves are widely used for thatching and for wrapping food products, such as cassava. They are used for covering pots in which bananas, yams or taro are cooked, and for baking meat and fish during field camps. In Cameroon they are used as cushion under sleeping mats and made into articles such as instant containers, plates, pots, cups, funnels, fans and parasols. Split petioles, with the central pith scraped out, are used for tying; they are also plaited into mats and baskets. The stems are recorded to be used for making cords, fish traps and baskets.
In Côte d’Ivoire the seeds are credited with expectorant and emetic activity and they are used against pulmonary problems such as cough and bronchitis. For this purpose, they are ground, mixed with water or palm-wine and drunk, or they are taken as small pills. A paste made of pounded seeds and water is applied on abscesses. In Gabon the rhizome is an ingredient of a decoction taken for the treatment of pulmonary problems.
In Nigeria the dried leaves are stored with kola nuts to preserve the nuts.
Production and international trade
Information on local trade is not available.
The fruit pulp is said to be edible in Ghana, but in Gabon the fruits are recorded not to be edible.
Adulterations and substitutes
A range of other Marantaceae species are similarly used for thatching, packing, wrapping, tying and weaving.
Perennial, erect herb with rhizome and tufts of c. 10 imbricate leaves around a central stem terminated with a single leaf and a lateral inflorescence. Leaves distichous; petiole up to 1.5 m long, sheathing at the base, sheath pubescent, the uncalloused and calloused parts of the petiole not separated by a joint, apical calloused part up to 6 cm long, transition of the petiole into the midvein marked by a V-shaped beak on the upper surface, but continuous on the under surface; blade elliptical to linear-elliptical, 20–40 cm × 10–20 cm, base attenuate. Inflorescence of 1 or more racemes; raceme up to 7 cm long, sessile or with peduncle up to 6 cm, condensed, internodes c. 5 mm long; abaxial bracts overlapping, 10–20 mm × 8–10 mm, persistent, each with 4–5 cymules; cymule 2-flowered, backed by a an adaxial bract. Flowers bisexual, zygomorphic; pedicel c. 1 mm long; bracteole c. 1.5 mm long, acuminate, fleshy, smooth; sepals free, equal; corolla c. 10 mm long, tubular below, with 3 lobes, pinkish white to purplish or yellowish; staminodes and stamen in 2 cycles, at the base forming a tube fused to the corolla tube, outer cycle consisting of 2 petaloid staminodes, inner cycle consisting of 1 stamen and 2 staminodes, of which 1 hooded with a sword-like appendage; ovary inferior, glabrous, 3-locular. Fruit almost globose, 12–15 mm in diameter, with inconspicuous sutures, indehiscent, fleshy, orange-red, wrinkled when dry, 3-seeded. Seeds subpyramidal, oblique, without aril.
Other botanical information
Sarcophrynium comprises 4–7 species, distributed in the forest regions of tropical Africa.
Within Sarcophrynium brachystachyum 2 varieties are distinguished: var. brachystachyum, with glabrous leaf blade except for the midvein on the upper surface, and var. puberulifolium Koechlin, with fine pubescence on the undersurface of the leaf blade.
Growth and development
Flowers open early in the morning and start wilting at around 11.00 in the morning. Pollination is by bees.
Sarcophrynium brachystachyum occurs in forest understorey, particularly in humid locations or along streams. It is also recorded to occur as a weed in oil palm plantations.
Propagation and planting
Natural reproduction is rapid.
In view of its wide distribution and rapid natural reproduction Sarcophrynium brachystachyum is not threatened with genetic erosion.
Sarcophrynium brachystachyum yields many useful products, but little information is available on the species. Studies on its market value and trade routes, its properties, its germination characteristics, and its phenology seem worthwhile.
