Wiborgia leptoptera is a fairly erect shrub or shrublet reaching heights from 30 cm to 1,2 m. Its flowers are pale yellow, appearing in short racemes on side-branchlets, from before midwinter to early spring.
The species distribution is in the west of the Western Cape, northwards from Malmesbury to the Cederberg and southern Namaqualand, slightly into the Northern Cape. The photo was taken in the Biedouw Valley.
The habitat is clayey slopes among scrub and fynbos. Neither of the two subspecies, viz. subsp. leptoptera and subsp. cedarbergensis is considered to be threatened in its habitat early in the twenty first century (Bond and Goldblatt, 1984; iNaturalist; www.worldfloraonline.org; http://redlist.sanbi.org).
