Alocasia sanderiana, commonly known as the kris plant or Sander's alocasia, is a plant in the family

critically endangered in the wild by the International Union for Conservation of Nature
.

Etymology

The species is named after the botanist Henry Frederick Conrad Sander.

Description

Alocasia sanderiana is also known as the kris plant because of the resemblance of its leaf edges to the wavy blade of the kalis sword (also known as kris or keris). It is a tropical perennial, with upright leaves, usually growing to a height of 2 ft (60 cm) long.[2]

It usually has a single to a few leaves, interspersed with papery

pinnatifid.[2][3]

It has creamy-white

spathe that covers the tiny flowers. Female flowers are grouped at the lower part of the inflorescence
, whereas the male flowers are at the top. The rhizome of A. sanderiana is vertically placed and is known as root stock. The fruits, orange-red berries, are not edible.

A. sanderiana can be distinguished from similar

peltate - the petiole is attached to the lower surface of the leaves, and the inner leaf margins of the lobes are fused at a width of 5 mm (0.20 in) or more. It can be distinguished from Alocasia micholitziana (which is also peltate and also endemic to the Philippines), in that the latter has leaves with a velvety (not glossy) texture that do not have cataphylls at the base.[4][2][3]

Uses

A. sanderiana is cultivated as an

house plant. It is also used in making nanomaterials to fight bacteria in vitro.[5]

Cultivation

Alocasia plants are cultivated in pots as indoor plants in a substrate of sod, peat, humus and sand (2:2:3:2) with moss or pieces of charcoal added. In spring and summer give a liquid compound fertiliser 2 times a month. Alocasia needs extra light in winter; it grows better with high air humidity. Ambient air humidity is maintained at 80-85%.[6] In spring and summer, the Alocasia needs regular watering and frequent spraying. Multiply by grafting, dividing rhizomes or sowing seeds in spring in a warm place.[7] In winter the temperature needs to be relatively high - not lower than 17 °C for all the species described, in summer the optimum temperature is 21 °C. In domestic conditions, water abundantly during the growing season as soon as the soil surface in the pot dries out,[8] from autumn watering is reduced, and in winter moisten the soil only after a day or two after the top layer of substrate dries out. The soil should not be allowed to dry out, but excessive moisture is also extremely harmful. Any water that has leaked into the tray should be poured out a quarter of an hour after watering.[9]

Conservation

Alocasia sanderiana is

₱1,000,000.[10]
