 Historically , there has been some confusion between Ficus obliqua and the related F. rubiginosa . F. obliqua can be distinguished by its smaller fruit on shorter stalks and its glabrous ( hairless ) leaves ; in addition , the petioles have ascending hyaline hairs . Some forms of F. rubiginosa have both leaves and petioles glabrous while others have both covered in fine fur . The syconia of F. obliqua are smaller , measuring 4 @.@ 3 – 11 @.@ 9 mm long and 4 @.@ 4 – 11 @.@ 0 mm in diameter , compared with 7 @.@ 4 – 17 @.@ 3 mm long and 7 @.@ 6 – 17 @.@ 3 mm diameter for F. rubiginosa . Ficus brachypoda is a lithophytic plant from arid northern and western Australia , with a short petiole and leaf shape aligning it with Ficus platypoda .
