Description

Author : Tom Croat

Description: Robust rosulate epiphyte, rarely on rocks; stems short with mass of thick roots; cataphylls thick, fist-like, cucullate, rounded at apex, drying brown, remaining intact, ultimately becoming fibrous at base. Leaves erect; petioles flattened or sulcate adaxially, rounded abaxially, 5-23 cm long, 1-2 cm diam.; geniculum 1.6-2 cm long; blades obovate to oblanceolate, moderately thick, acuminate at apex, attenuate, sometimes cuneate (rarely rounded or subcordate) at base, (32-) 40-180 cm long, (9-)13-50 cm wide; both surfaces semiglossy; the midrib acutely raised above and below; primary lateral veins 9-14 per side, raised above and below; lesser veins less conspicuous. Inflorescence usually pendent, shorter than leaves; peduncle 16-80 cm long; spathe lanceolate-linear, moderately thin, purple or green sometimes tinged purple, 4-45(-50) cm long, 1-5 cm wide; gradually cuspidate-acuminate at apex, rounded to truncate at base; spadix dull green soon tinged throughout with lavender (B 6 K Purple 6/5), 6-34(-47) cm long, 0.6-1.5 cm diam. at base, 2-7 mm diam. at apex; flowers rhombic, 2.4÷2.5 mm in both directions, the sides straight to sigmoid; 6-7 flowers visible in the principal spiral, 8-12 flowers visible in the alternate spiral; tepals matte, lateral tepals 1.2-1.3 mm wide, the inner margins broadly rounded; pistils green, emergent but not raised; stigma linear, ca. 0.9 mm long; stamens emerging in a slow progression from the base; anthers pale yellow, held at edge of tepals and laying over pistil; thecae ellipsoid; pollen pale yellow-orange, fading to white. Infructescence with spadix to 60 cm long; berries red, oblong-elliptic, rounded at apex, 1-1.5 cm long; seeds 2, oblong, flattened, 3.3 mm long.

Taxonomic notes: Anthurium salvinii has long been called A. tetragonum but that name is a synonym of A. schlechtendalii, a species ranging from Mexico to Honduras or Nicaragua on the Atlantic slope. Although leaves of the two species are very similar, A. salvinii is a member of section Pachyneurium and can be distinguished by its long-tapered, pale lavender spadix, long-tapered spreading spathe, and fist-shaped, cucullate cataphylls. In addition the leaves of A. salviniae usually dry darker and thinner. Anthurium schlechtendalii usually has a shorter, blunter spadix and a short, thick spathe that is usually reflexed and often twisted. The spadix is darker violet-purple and is not at all glaucous at anthesis.

Uses: This species sometimes is cultivated as an ornamental.

Etymology: The epithet honours Osbert Salvin, an english naturalist co-author of Biologia Centrali-Americanum (1879-1915), who collected the type.
