Anecdotes on plants

Origins South China, including Guangdong, Guangxi, Yunnan, Hainan and Fujian. It is also distributed throughout Japan and Southeast Asia, Australia and the Pacific Islands.
Meanings of name When observing the Common Red-stem Fig, people often impress that it is worthy of its Chinese name “Green Fruit Fig (青果榕)”. They are shocked by the large number of densely packed figs in green colour, which are arranged like an army of green soldiers protecting their fortress. Interestingly, these “green fruits” only grow from old branches and the trunk of the tree, in a growing pattern known as “cauliflory”.
However, the figs of the Common Red-stem Fig are not limited to being green in colour. At maturity, the figs turn yellow or red, hence its other Chinese name “Variegated Fig (雜色榕)”. The species epithet “variegata” in its scientific name exactly refers to the “variegated” fruits in Latin.
Ecology The Common Red-stem Fig not only provides shelters for fig wasps, but also acts as the host plant of Indian lac insect (Kerria lacca (Kerr, 1782)) and Common Mapwing (Cyrestis thyodamas (Doyere, 1840)). Additionally, the Short-nosed Fruit Bat (Cynopterus sphinx (Vahl, 1797)) consumes the fruits of the Common Red-stem Fig for nourishment and helps spreading its seeds.
