Ficus maclellandii is a strangling fig native to  N E India, S China, Thailand and N Malaya. The southernmost distribution of F. maclellandi in N. Malaya overlaps with the northernmost distribution of F. binnendijkii which extends from Java, Borneo, and Sumatra north up the Malay Peninsular to S Thailand.

These two fig species are obviously  closely related  and share a common characteristic unique in Section Conosycea figs. Both species share a juvenile phase  in which the leaves are long and narrow (lanceolate)  and look quite different  from the shorter and wider adult leaves. 

The juvenile leaves  of both species stay true to type if a juvenile branch is planted as a cutting. As a result cloned branches of both species are frequently  grown as house plants throughout the world.

Ficus maclellandii  is not found wild in Borneo but is widely grown for landscaping . However F. maclellandii fig fruit in Borneo are always sterile (no seeds) because  there are no partner fig wasps of Ficus maclellandii  in Borneo to pollinate the tiny flowers inside the fig fruit. Birds and mammals do not eat sterile figs.

The adult  leaves of Ficus maclellandii are easy to distinguish  from the adult leaves of F. binnendijkii as F. maclellandi have only faint side veins of the  underside of the leaf whilst F. binnendijkii  fig leaves have a very strong pair of basal veins which surround the edge of the leaf blade and which are very obvious both on the upper and under side of the leaves. For a comparison see this link to F. binnendijkii
