Notes
1. This cultivar is accepted here follow the Flora Fauna Web (https://www.nparks.gov.sg/florafaunaweb/flora/2/9/2901). It differs from Ficus benghalensis L. by having cup-forming leaves, petioles with 1–2 leafy appendages, and aerial roots with a few and not forming accessory trunks. Some botanists accepted as a distinct species F. krishnae C.DC. (Vaid, 1963 as cv trifoliata; Tiwari et al., 2015; Mahima et al., 2021), as F. benghalensis var. krishnae (C.DC.) Corner (Chaudhary et al., 2012), and as a synonym of F. benghalensis (Govaerts, 2001; Berg & Corner, 2005).

2. The common names, Krishna cup or Krishna’s butter cup, refer to the myth that Lord Krishna rolled the leaf of this tree to hide the butter after he was caught by his mother, since then, the leaves have retained this shape.
