Inserat erstellen →Alocasia portei is a massive, thick-stemmed plant with a base that thickens even more with age. It can reach a height of 6 metres (20 feet) and sometimes 10 m (33 ft) in ideal environments. It is an evergreen that grows best in tropical forests. Mature plants have a leathery texture.[citation needed] Foliage The leaves of Alocasia portei typically grow only one on each stem. They can be 1.5 m (5 ft) or longer. Leaves are dark green, and the veins are lighter and stand out. The petioles are dark brown.[citation needed] Flowers Inflorescences grow from the center of the crown of leaves, on stalks up to 30 centimetres (12 inches) in length. The spaths are longer than the spadixes and measure up to 40 cm (16 in) long and are green or dark brownish-green. Spadixes are put into two groups – the male zone and the female zone. Male zone spadixes are about 8 cm (3.1 in) long and are white-ish, while female zone spadixes are about 4 cm (1.6 in) long and white. Fruit The fruits of Alocasia portei are oval and grow all over a stalk of about 10 cm (4 in) long. There is limited information about the colour of the fruit of Alocasia portei.[according to whom?]

Endemic to the Philippines; Luzon. However, A. portei is anecdotally reported to be common and widespread in the Philippines, although botanical collections have been made on only very few occasions, probably on account of its enormous size.
Secondary forest at low to medium elevations.
