Drosera indica

Drosera indica is an insectivorous plant, a sundew native to tropical countries throughout the world, from Australia and Asia to Africa, but absent from the neotropics.[1] Together with D. hartmeyerorum it makes up the section Arachnopus.

Description[edit]

Drosera indica with trapped insects, Kumbla, Kerala

D. indica is an unbranched, annual herbaceous plant, supported by a fibrous root system and reaching a height of 5–50 cm (2–20 in). Leaves are narrowly linear, up to 10 cm [4 in] long with 1-1.5 cm [0.4-0.6 in] pedicels.[2] Young plants stand upright, while older ones form scrambling stems with only the newest growth exhibiting an upright habit. The plant can be yellow-green to maroon in color. Flower petals can be white, pink, orange, or purple.[2] Its chromosome count is 2n=28.[3]
