Drawing of Ficus retusa L. A: leaf; B: fruit-bearing shoot; C: stipules; D: syconium; E: male flower; F: female flower; G: fruit (achene); H: habit. In their 1918 publication of the Atlas der Baumarten von Java, Koorders & Valeton labelled this drawing as Ficus truncata Miq., a name which is now considered illegitimate and a synonym of Ficus retusa L. The confusion was later disentangled by E. J. H. Corner (Taxonomic Notes on Ficus Linn., Asia and Australasia, The Gardens' bulletin, Singapore vol. XVII, 1959). See also: C. C. Berg & E.J.H. Corner, Flora Malesiana, Ser. I, Vol. 17 / Part 2 - Moraceae: Ficeae, 2005. L. B. Chaudhary et al., Synopsis of the Genus Ficus L. (Moraceae) in India, Taiwania, 57(2): 193-216, 2012.
