Anthurium salvinii

Anthurium salvinii

Anthurium salvinii or Birdnest Anthurium is a spectacular plant with leaves up to 2 m long.

Although it comes from the tropical rainforest, it seems possible to grown it as a houseplant.

All parts of plant contain calcium oxalate crystals, an irritant to the mouth and esophagus. Toxic to cats and dogs.

Description:

Anthurium salvinii is epiphytic, sometimes lithophytic. The trunk is up to 6 cm in diameter. The roots are dense, usually ascending, sometimes descending, greenish to white, hairy, quite short and tapered, 3-6 mm in diameter. They wear thick cataphylls with a hat, rounded top, which are brown but remain on the plant and eventually become fibrous at the base.

The leaves are spread to upright. The petiole measures 5-23 cm in length, 10-20 mm in diameter, D-shaped to terete, flattened or with deep grooves, margins not prominent. The petiole has a typical geniculum (knee) which is paler and thicker than the petiole, 0.7-2 cm long. The leaf blade is moderately coriaceous, obovate to broad elliptical, acuminate to obtuse at the top, rounded and sometimes heart-shaped at the base, 40-180 cm long, 13-50 cm wide, the margin is slightly wavy, both surfaces slightly shiny, medium green on top, slightly paler below.

The inflorescence is spreading to hanging, shorter than the leaves. The flower stalk is 16-80 cm long, 2-5 mm in diameter, almost cylindrical. The spathe is spread or recurled, tough, purple or sometimes green tinged with red or purple, lanceolate-linear, 10-40 cm long, 1-2.5 cm wide, gradually acuminate at the top, rounded or acute at the base. The spadix is light green when immature, then changes to a dull lavender or violet-purple, slightly curved, 10-34 cm long, 4-15 mm in diameter near the base, 2-7 mm in diameter towards the top. The flowers are diamond-shaped, 2.5 mm in both directions.

The infrutescence is a spadix of up to 60 cm long with red berries, oblong-ellipsoid, apex rounded, 10-15 mm long. The mesocarp is transparent and gelatinous. There are 2 seeds per berry, oblong, oblate, 3-5 mm in length.
