Mohapatra, Abhipsa & Janarthanam, M. K., 2020, Cystolith micromorphology in selected taxa of Ficus L. (Moraceae) in India and its taxonomic implications, Phytotaxa 436 (2), pp. 167-181 : 178

Sections- Sycomorus and Sycocarpus

In F. racemosa , F. auriculata Lour. (section- Sycomorus ) and F. hispida L. f. (section- Sycocarpus ) cystoliths are present only on the abaxial side and spherical shaped ( Figure 3 D-F). This is in agreement with the observations of Ummu-Hani & Noraini (2013) on F. hispida . The sculpture pattern in F. racemosa and F. hispida is tuberculate whereas moderate aculeate in F. auriculata .
