Pelargonium greytonense

Pelargonium greytonense is a much-branched, erect shrub growing to about 1 m in height. It is sometimes aromatic although not always. Older stems become woody, younger ones covered in fine hairs, some of these hairs glandular.

The three rounded leaf-lobes form a triangular, sometimes rounded leaf-shape with roughly dentate (toothed) margins. The fresh green to slightly yellow-green blade surfaces are uneven, slightly folded in along the veining.

The flowers appear in umbel-shaped groups of two to nine. They are white to pale pink. The upper two petals have dark red markings, the lower three are unmarked and much narrower.

The species has much unevenness of characteristics as may be common in young species. There has been a thought mooted that the plant originated as a natural hybrid between P. hermanniifolium and P. papilionaceum. The species is, however, recognised by SANBI. 

The distribution is limited in the Western Cape to the Riviersonderend Mountains, common near the town of Greyton. 

The habitat is sheltered fynbos ravines and sandstone slopes covered in fynbos or renosterveld. The habitat population is deemed vulnerable early in the twenty first century, due to alien vegetation invasion and possibly still timber plantations (Lalli, 2005, Witwatersrand University, wiredspace.wits.ac.za; Van der Walt, 1984; irapl.altervista.org; http://redlist.sanbi.org).
