Gnidia daphnifolia L.f.

Suppl. pl.: 225 (1782).
Dais madagascariensis Lam. (1786), Lasiosiphon pubescens (Lam.) Decne (1841), Lasiosiphon baroni Baker (1890).
Origin and geographic distribution
Gnidia daphnifolia is endemic to Madagascar.
The bast fibre is used for cordage. Like that of many other species in Madagascar, the bark was formerly beaten on a mallet to obtain a kind of felt used for cloth. As technology evolved, fibres were extracted by crushing the bark, after which they were combed or scutched, making them suitable for spinning and weaving. Gnidia daphnifolia is also one of the species of which the bark fibre is locally made into ‘Antaimoro paper’, a paper of excellent quality made into articles such as stationary, envelopes, cards, notebooks, photo albums, lampshades and gift bags.
The bast fibre is fine and silky.
Shrub up to 2 m tall; branches glabrescent, outer bark reddish brown, striate. Leaves with petiole up to 5 mm long; stipules absent; blade obovate-lanceolate to oblong, 20–70 mm × 8–20 mm, base attenuate or slightly cuneate, apex obtuse, sparsely hairy or glabrous. Inflorescence an axillary or terminal head 1.5–2 cm in diameter, 15–20-flowered; peduncle 1–5 cm long, hairy, greyish green; involucral bracts often fused at the base, acuminate, hairy. Flowers bisexual, regular, 5-merous, red, orange or yellow; calyx tube cylindrical, 12–18 mm long, lobes ovate to oblong or obtuse, 2–3 mm long; petals inserted in the throat of the calyx tube, alternate with calyx lobes, scale-like, ovate-oblong, up to 2 mm long, membranous; stamens 10, in 2 whorls of unequal length, the upper whorl inserted in the throat of the calyx tube, the other one inserted lower; ovary superior, 1-locular, hairy or glabrous, style filiform. Fruit oblong, 4–5 mm long, enclosed by the persistent base of the calyx tube, covered with long stiff whitish hairs.
Gnidia comprises about 140 species, mainly distributed in tropical Africa, with 20 species endemic to Madagascar, but it also extends into Arabia, western India and Sri Lanka. The bast fibre of Gnidia danguyana Leandri, a shrub endemic to Madagascar, is used for the same purposes as that of Gnidia daphnifolia.
Gnidia daphnifolia occurs in sandy and rocky locations.
Genetic resources and breeding
It is unclear whether Gnidia daphnifolia is threatened by genetic erosion.
Little information is available on Gnidia daphnifolia and its fibre properties. Its use in the niche market for high-quality ‘Antaimoro paper’ may increase with increasing tourism to Madagascar.
