Crassula barklyi (“Bandaged finger”)

Plants of this species are sparingly to densely branched (usually from the base) and form clusters up to 9 cm in diameter.
The columnar plant bodies are usually erect (rarely more or less flat on the ground);  20-90 mm long and 6-15 mm thick.
Flowering occurs from May to October;  the flask-shaped flowers have cream, 9-11 mm long petals.
The species is found in the western part of Namaqualand from near Port Nolloth to the Vanrhynsdorp area, on exposed quartz gravel flats and gentle slopes, rarely on rocky outcrops and in shallow pans on rocks.


Conophytum calculus ssp. calculus

The Latin word calculus means pebble and in this case probably refers to both the roundness and the firmness of the plant bodies.
These bodies are to 30 mm diameter, ball- to barrel-shaped, very firm, whitish-green to pale yellowish-green, without any markings; they form a hemisphere with age.
The flowers are open at night (sometimes staying open during cool mornings) and are said to smell strongly like cloves or carnations; they are golden yellow to deep reddish orange and appear in April-June.
The plants occur in full sun on salty quartz flats and gentle slopes in the Knersvlakte.

Crassula brevifolia ssp. brevifolia

This very variable taxon occurs from southern Namibia to the Cederberg in South Africa, but mainly in the mountainous area of Namaqualand near Vanrhynsdorp, in rock crevices or between boulders, often in very exposed positions.

The plants form much-branched shrublets up to 0,5 m tall. The leaves are green, sometimes turning yellowish green or purplish red; they are almost triangular in section, usually 20-35 mm long (sometimes as short as 10 mm or as long as 50 mm) and 2-4 (sometimes 6) mm wide, about as thick as they are wide.
In autumn/early winter (March-June) the flowers appear, which as a rule are yellow-green, rarely white with a pink tinge.



Argyroderma delaetii (part 1 of 2)

No less than 25 synoniems have been recorded for this species, so it will come as no surprise that it is quite variable.
As a rule, the plants consist of only one pair of leaves, rarely 2 or 3. These leaf-pairs are 20-50 mm long and 15-30 mm wide, 
sunken into the ground. Old leaves stay on the plants for 1 or 2 years.
The flowers appear in April – June; they are 20-50 mm in diameter and may be white, pink, red , magenta, or yellow (see part 2). Even within one population one can come across all these colours.
The plants are locally abundant on flats or slopes rich in quartz pebbles in the Vanrhynsdorp area.

Trip to Namaqualand

Earlier this month I was on an 8-day trip to Namaqualand with a couple of friends, hoping to see Argyrodermas and Conophytums in flower.
In spite of the drought  we saw a lot of interesting plants, a few of which are pictured below.
Many other pictures should find their way into posts on succulents from the area.

Malephora mollis

It is usually easy to identify a plant as a Malephora.  Beyond that however, things are rather muddled up. So it is with some trepidation that I attach a species name to the pictures shown here.
M.  mollis is described as a profusely branched shrub up to 50 cm tall, with leaves three-angled to round in cross-section and to 20 mm long and about 3 mm thick.
The distribution area is given as Laingsburg and both the flowering time and the habitat as unknown.
The photos were taken on stony flats northwest of Laingsburg, between early August and mid-October.

Kewa (Hypertelis) salsoloides

Sometimes, writing a post for this blog involves quite a bit of detective work, which may at times be a bit tedious, but often also gives interesting new insights.
For many years, I have known the subject of this post as Hypertelis salsoloides. When I started collecting info on it, I found out that neither the List of southern African succulent plants (1997), nor the Illustrated handbook  of succulent plants (2002) mentioned it. This in spite of the fact that both publications take a rather liberal view on what is a succulent.
So was this plant, which I had known for over sixty years as a succulent, really a succulent?
Older literature such as Jacobsen’s  A handbook of succulent plants (1960) and Das Sukkulenten Lexikon (1981) did not mention the name either, but they did cite Pharnaceum salsaloides, as a synonym of Hypertelis verrucosa.
On the other hand,  the 2 volumes of  “Plants of the Greater Cape Floristic Region”, published in 2012/2013, both mention Hypertelis salsoloides as a current name.
Shortly after they appeared  (2014), a new genus (Kewa) was established in the Molluginaceae, the family Hypertelis belongs to. The type of the genus is Kewa salsoloides and it is stated that  “The genus differs from Hypertelis sensu stricto in having succulent, alternate, terete leaves…..”
What a relief to find out that this dainty little plant was indeed a succulent all along :-).

The species is widespread and often abundant across the interior of southern Africa, from Namibia and Zimbabwe to the Little Karoo, on dry sandy and loamy lowland  flats.The plants are often much-grazed and form dwarf, short-lived shrublets up to 30 cm tall with leaves up to 3 cm long and 0.5 cm wide.
The flowers are white to pink and about 1 cm in diameter; they appear mainly from September to March. The flower stalks bear relatively big warts, which sets the species apart from its siblings.
