Dischidia
Tropical climbing plants with unusual leaf forms that host ants
Dischidia is a genus of tropical epiphytic plants in the dogbane family. Native across South and Southeast Asia to the Pacific, some species grow on trees and form hollow or overlapping leaves that shelter ants in exchange for nutrients.
- Grows as an epiphyte in tropical forests without soil
- Forms hollow or tile-like leaves that house ants
- Found from India and China through Southeast Asia to the Pacific
- Leaves adapt by stopping edge growth while the centre expands
- Over 120 accepted species as of early 2025
What does Dischidia look like?
Dischidia plants climb trees in warm forests. Their leaves come in two special types: some are hollow and bulb-like, forming tiny chambers; others lie flat and overlap like roof tiles against bark or rock. Normal heart-shaped leaves also grow alongside these modified ones. The flowers are small, but details about their colour or scent are not given in the sources.
Where does Dischidia come from?
These plants grow wild across a wide tropical belt, from India and southern Bhutan through mainland Southeast Asia to parts of Indonesia, Malaysia, Singapore, Papua New Guinea, and even northeastern Australia and Pacific islands like the Marianas. They thrive wherever frost does not occur and are often found in forest canopies.
When and how Dischidia blooms
Dischidia species grow as epiphytes, meaning they live on other plants without harming them. Many develop unique leaf structures: bullate leaves form when the leaf edges stop growing but the centre keeps expanding, eventually curling into a sealed pouch. Others produce imbricate leaves that cling tightly to surfaces, with roots filling the space underneath, used by ants for nesting.
Kinds of Dischidia
Over 120 species are recognised, including Dischidia major, D. vidalii, and D. complex with bullate leaves, and D. imbricata, D. platyphylla, and D. astephana with shingling growth. A few, like D. ovata, D. nummularia, and D. oiantha, became popular in the houseplant trade between 2015 and 2020.
What Dischidia means
Dischidia shares its range with the better-known genus Hoya but remains less studied. Its most notable feature is mutualism with ants: the plants offer shelter in modified leaves, and the ants may aid in pollination or nutrient supply. This relationship has shaped the evolution of its unusual leaf forms.
Questions people ask about Dischidia
Where does Dischidia come from?
It is native to tropical regions including India, China, Bhutan, mainland Southeast Asia, Indonesia, Malaysia, Singapore, Papua New Guinea, northeastern Australia, and Pacific islands.
What makes Dischidia leaves unusual?
Some species have hollow, bulbous leaves that form chambers, while others have flat, overlapping leaves that cling to surfaces like shingles, both used by ants for nesting.
How do Dischidia and ants interact?
The plants provide shelter in modified leaves, and in return, ants may help with pollination or supply nutrients, a symbiotic relationship seen in several species.
Is Dischidia grown as a houseplant?
Yes, a few species like D. ovata and D. nummularia entered the houseplant trade between 2015 and 2020 and are cultivated in temperate areas under protection.
