Hydnophytum formicarum (Hydnophytum formicarum)

Description

Hydnophytum formicarum is a species in the genus Hydnophytum, thus making it an epiphyte and a myrmecophyte. It is native to Southeast Asia and is considered critically endangered in Singapore. This epiphyte grows a tuber also known as a caudex, that is spineless and contains chambers; many of which are connected to one another. These tubers may grow 10–55 cm in diameter with two to four stems that reach about 60 cm long. The leaves, which grow 4–15 cm long and 2–7 cm wide, are opposite, elliptical and have a leathery texture. Flowers are four-merous, white, and occur in groups of 3-10, which then yield orange, fleshy fruits 6–7 mm in diameter.
