Anthurium chucantiense

The genus Anthurium has a particularly high level of endemism and this species adds to the list. Due to its restricted range and nearby threats in the form of agriculture and logging, the authors that described this species suggested it should be considered Critically Endangered [CR].

Identification

This species has short stems (around 10 cm long). The areas between the nodes (where the leaves attach to the stems) are longer lower down the plant and shorter near the apex (1 - 1.5 cm long).

Growth form: Epiphytic herb.

Foliage: Petioles (leaf stems) 2 - 3 mm wide and quite long (8 - 23 cm). Leave are large and narrowly oblong (24.5 - 45.5 com long / 3.5 - 8 cm wide; 5.5 - 7.4 times longer than wide), 2-3 times longer than the petioles, dark green and semiglossy above, paler and matte below.

Flowering structure: Erect. Stem quite long (26.5 - 54 cm), 2 mm wide. Spathe green/medium-green, bending backwards towards the stem 0.2 - 2cm below the spadix, 3 - 8 cm long / 1 - 1.9 cm wide. Spadix rounded, erect, 5.7 - 12.5 cm long / 2 - 4 mm wide, yellowish-green turning pale orange lower down. Flowers 4 visible in the main spiral, 3 - 6 in the alternate spiral, slightly protruding stamens, translucent filaments, yellowish anthers.
