There are many small side-branches on a Wiborgia leptoptera shrublet. They are straight and rigidly woody, appearing spiny. These branchlets usually bore the flowers during their first season when they were soft with silky hair coverings.
The trifoliolate leaf has no petiolules on its three leaflets, but does have a petiole for the whole leaf that varies in length, from less than 0,5 mm to over 5 mm long. The narrowly obovate leaflets are silky grey, with tiny mucros at their rounded or notched tips (Bond and Goldblatt, 1984; iNaturalist; www.worldfloraonline.org).
