Paropsia perrieri Claverie

Protologue
Ann. Mus. Colon. Marseille 7: 59 (1909).
Family
Passifloraceae
Origin and geographic distribution
Paropsia perrieri is endemic to the northern-most part of Madagascar.
Uses
Fibres from Paropsia perrieri are used in textile fabrics, although they are not very durable.
Botany
Shrub or small tree up to 15 m tall; bole up to 25 cm in diameter; branches ferruginous-tomentose, lateral ones always longer than terminal one, hairy when young. Leaves alternate, distichous, short-lived; petiole thin, 5–8 mm long; blade broadly oblong, (3.5–)5–10 cm × (2–)2.5–4(–6) cm, base rounded, apex tapering, margin entire or somewhat toothed, papery to thin-leathery, both surfaces shortly ferruginous-tomentose, lateral veins in 8–10 pairs. Inflorescence an axillary cyme 2–10 mm long, on specialized branches bearing leaves, long-pedunculate, (1–)2–4-flowered; bracts linear, 4–5 mm long; flowers bisexual, fragrant; pedicel 10–25 mm long; sepals 5, oblong, 10–12 mm × 4–5 mm, shortly connate at base, apex obtuse, reddish tomentose outside, white to greyish velvety inside; petals 5, narrowly oblong, 8–10 mm × 3.5–4.5 mm, thinner than sepals, white, velvety on both surfaces; corona laciniate, 2.5 mm long, in bundles in front of the petals; stamens 5, filaments 5–6 mm long, anthers c. 2.5 mm long; ovary on a 12 mm long reddish hairy gynophore, obovoid, 1-celled, styles c. 3, 1.5–2 mm long, free, with thick stigmas. Fruit a nearly globose 3-valved capsule 12–15 mm in diameter, tomentose. Seed compressed ovoid, 5–7 mm × 1–2 mm, with thin, entire, fleshy aril. Seedling with epigeal germination.
Paropsia perrieri flowers in October–November.
Paropsia comprises 12 species, of which 5 occur in mainland tropical Africa, 6 in Madagascar and 1 in South-East Asia.
Ecology
Paropsia perrieri is rather rare in dry deciduous forest, at low altitudes.
Management
Paropsia perrieri only occurs wild.
Genetic resources and breeding
Paropsia perrieri occurs only in a small part of Madagascar. It is also rare and therefore at risk of genetic erosion.
Prospects
It is unlikely that Paropsia perrieri will become an important source of fibre.
