Pelargonium torulosum E.M. Marais is a tuberous species from the Cape Province in South Africa, Klipplaat, and Sutherland where it grows in sandy soil under bushes. Note the small tubers, which spread at ground level. (Section Ligularia). Photos David Victor.
Pelargonium triandrumE.M. Marais is a tuberous species from the Cape Province, in South Africa, along the Olifants River from Clanwilliam to Algeria. It grows on sandstone in broken succulent veld or dry fynbos. This species has four petaled flowers, which may be cream to pale yellow, with wine red feathering on the upper two. Note the prominent stamens, presumably for a particular pollinator (see also Pelargonium oblongatum, which is not closely related). It flowers from October to December. The name is derived from the fact that it has only three, very long fertile stamens. (Section Hoarea, punctatum group). Under cultivation conditions this species requires a treatment similar to others in the Hoarea Section. In dry winter conditions it requires additional water to maintain the large leaves in full growth and avoid desiccation or premature dormancy. In bloom, usually in May and June in southern California, it provides a striking, delicate appearance in bloom. The first three photos from David Victor. The last photo from Andrew Wilson.
Pelargonium trifoliolatum E.M. Marais is a tuberous species from the Southwestern Cape of South Africa, on the western escarpment, from Piketberg to Groot Drakenstein. It grows on clay soils in renosterveld and sand in fynbos. Flowers can be cream, yellow or pink, with wine red blotches on the "knees" of the petals. It flowers from October to January. The name refers to the incision of the leaves. (Section Hoarea, Heterophyllum Group). Photos David Victor.
Pelargonium triste (L.) L'Hér. is a geophyte growing to about 50 cm high with a large subterranean tuber and tuberous roots with carrot like leaves (finely divided into numerous hairy segments) and flowers that are dull yellowish green to brownish purple edged with a lighter margin. Flowers are scented of cloves at night. It grows on sandy flats and lower slopes in Namaqualand and over a broad region of the Western Cape and also can be found in flower over a long period (August to February). The first two photos were taken in the Tulbagh/Worchester area in different years by Bob Rutemoeller. The next two photos were taken by Mary Sue Ittner and Cameron McMaster in different years in September near Darling. The fifth and sixth photos were taken at Lion's Head by Bob Rutemoeller.
The first three photos below showing variation in flowers were taken on the same day near Bainskloof by Bob Rutemoeller and Mary Sue Ittner. The next two photos were taken August 2001 in Namaqualand by Mary Sue Ittner. The last photo was taken in Namaqualand by Cameron McMaster.
Pelargonium undulatum Pers. is a tuberous species from the Southwestern Cape area of South Africa, in the vicinity of Worcester, Karoo Poort, the Hex River Valley and further East. It grows in sandy soil or on shale in low karroid vegetation. Flowers are white, cream, yellow or pale pink, the upper two having a wine red blotch and the lower three a wine red stripe down the centre. The petal edge is undulate, giving the plant its name. It flowers from September to October. (Section Hoarea, Attenuatum Group). Photos David Victor.
Pelargonium vinaceum E.M. Marais is a tuberous species from Southern Namibia, Rosh Pinah, in the Richtersveld to South of Steinkopf, in South Africa. It grows in karroid vegetation in granites, shale or sand. Flowers may be cream to pale yellow, with wine red blotches in the centre of the upper two. It flowers from October to November.

The name refers to the flowers looking like English violets. (Section Hoarea, Pinnatum Group). Photos David Victor.
