This species is the only one in its genus and is endemic to the western part of the Little Karoo. The plants may occur in great numbers in clayey soils, usually with some quartz. Older leaves are often covered in an unsightly black fungus. The flowers appear in late winter and early spring.
The flowering plants were photographed near the Garcia Pass 13 Sept. 2011, the other three yesterday, at the southwestern border of the Anysberg Nature Reserve.
This species is sometimes regarded as a subspecies of D. microspermus. It occurs in the Kenhardt district of Namaqualand. The pictures were taken in early Sept. 2010.
One can encounter this species from southern Namibia to the Little Karoo. It is often locally abundant on gravelly flats and lower slopes. In spite of their lack of “rarity appeal”, it is always a joy to meet these plants in the field, because they are not only beautiful, but also show a great variation in size, shape and colour. The flowers may be white, cream or light pink and appear in October and November.
Unfortunately it is rather difficult to keep the plants neat and compact in cultivation.
More pictures to come.
These plants are endemic to the northwest corner of the Richtersveld, where they often grow half-hidden in the ground. The yellow flowers are up to 2.5 cm across and appear in late Winter and early Spring.
The photos were taken on 8 Sept. 2010.
This is the most common and widespread species in the genus, which occurs on the Knersvlakte in the southern part of Namaqualand. It will form mats of up to 30 cm in diameter over time. The flowers are up to 4.5 cm across and may be yellow, purple, or sometimes bright red.
The first picture was taken 15 July 2011, the others 9 Sept. 2009.
The last plant looks much greener and lusher, because it grows amongst Salsola and Drosanthemum bushes.
Many of the more interesting Pelargoniums are geophytes*. The fact that they are hidden part of the year somehow adds to their appeal. The species shown here is very variable as to the shape and size of its leaves, which can be undivided or finely dissected and smooth or hairy. The beautiful flowers may be white, pale yellow or pink and appear from October to December.
The photos were taken last Saturday directly behind my house, where the plants grow in open or lightly vegetated sandy patches as well as on rocky outcrops. Actually the first ones I noticed were growing in an open Eucalytus coppice there.
* Plants which store water and/or food in underground storage organs and die down each year, regenerating at the start of the new growing season from buds that are hidden below soil-level.
