    Ecology

    Anthurium cremersii is endemic to French Guiana (Cayenne) and is found only in the northwestern mountains at an elevation of 550-750 m in a Premontane wet forest life zone.

    General Description

    Epiphyte, 30-40 cm high; stems short; internodes 5 10 mm long, drying 4-8 mm diam., scurfy, irregularly and closely fissured, dark brown to brown, frequently covered with debris and pieces of intact cataphylls and pale cataphyll fibres; cataphylls c. 5.5 cm long, moderately coriaceous, acute at apex, mostly breaking off, promptly weathering and mostly deciduous, sometimes with fragments of epidermis and a few pale fibres. Leaves with petiole subterete, 10.4-16.3 cm long (averaging 12.7 cm long), 1.1-1.6 longer than blade, 3-4 mm diam., sheathed 1.5-3 cm; geniculum weakly sulcate, c. 1.5 cm long, scarcely distinguished from the rest of the petiole; blade ± elliptic, 8.7-13.4 cm long, 5.9-9.2 cm wide (averaging 16.6 x 7.1 cm), 1.8-2.3 longer than wide, (averaging 2.2 x), abruptly acuminate at apex, acute at base, subcoriaceous, drying dark brown above, brown below; midrib slightly raised, thicker and more prominent at the base, flattening out and narrowing towards the apex, somewhat convex and drying concolorous with the blade on the up per surface, somewhat flattened and slightly darker on the lower surface; primary lateral veins 8-12 per side, drying less conspicuous than the collective veins and scarcely more conspicuous than the interprimary veins, arising at a 40-55o angle; interprimary veins frequently branched; collective veins arising from one of the lowermost primary lateral veins, (3-)5-11 mm from the margins midway, sometimes loop-collecting the primary lateral veins; the upper surface minutely granular or areolate upon magnification with a sparse array of pale short lineations, a dense array of pale globular excrescences and a dense array of circular-raised gland-like structures, the latter also on the lower surface but much denser there. Inflorescence erect; peduncle 21.5-34.8 cm long (averaging 25.6 cm); spathe 2.8-3.4 cm long, 0.5-1.2 cm wide (averaging 3.3x 0.85 cm), oblong-lanceolate, green, cuspidate-acuminate at apex, reflexed, drying dark brown, peduncle 6.6-10.2 longer than the spathe (averaging 7.9 longer); spadix greenish yellow, 4.6-12.8 cm long (averaging 8.3 cm) (reported to 20 cm in de Granville & al. 7598 but not seen), drying 2.3-3 mm diam. Flowers 3.3 mm long, 4.4 mm wide, 2-3 visible per spiral; lateral tepals 2.2 mm long, 0.8-1 mm wide, the margins broadly rounded and drying paler; stamens held just above the tepals, anthers 0.4 mm long, thecae broadly ovate, moderately divaricate. Infructescence to 10 cm long; berries orange to orange-red, c. 5 mm diam.
