Anacampseros telephiastrum (Gemsboksuring)

This could well be the most common Anacampseros, both in the wild and in cultivation. In nature it occurs wide-spread from the Worcester to the Grahamstown area on rocky flats and slopes.
It is a robust species compared to its siblings, forming clumps up to 5 cm tall from a thick, fleshy root-stock.

The leaves are to 3 x 1.8 cm, arranged in rather lax rosettes. They are triangular in cross-section and range from egg-shaped to almost circular when seen from above, with an acute tip and short hairs (shorter than the leaves) at the base.
The relatively stout inflorescence is 5 – 15 cm tall, with 1 – 4 flowers.

After good rains the plants will resemble the one in the first picture.  

Under more stressful conditions the plants turn yellowish/brownish/reddish, so that they are often difficult to find (especially when they grow in crevices like the next three ones).

The dark pink flowers are 3 – 3.5 cm in diameter and open for 1.5 – 3 hours in the late afternoon and only when the sun shines. In dull weather they stay closed and pollinate themselves. Most flowers appear in November-December.

The basket-like fruits have a charm all of their own.sized_anactele2011_11_30#003_lzn

 

Avonia papyracea (part 1 of 2)

Even if one has no knowledge of Latin, it is probably easy to understand that papyracea means papery. This refers to the thin, white scales that cover the stems.
These scales are in fact modified stipules: outgrowths of the base of the leaf stalk. By reflecting and diffusing light, they act as sunshades. This effect, combined with controlled aeration*, reduces evaporation. The scales are also able to trap dew.
*It has been noted that in hot, dry conditions the scales tightly overlap each other like roof tiles, whereas in cooler and therefore damper weather they can open out to some extent so that the leaves are more exposed.
As Gordon Rowley in “Anacampseros, Avonia, Grahamia” (1995) remarks, it seems surprising that such an efficient adaptation has, apparently, evolved only once.

The scales are about 5 mm long and wide and hide the minute leaves.
The stems are usually about 5-8 cm long and 0.7-1 cm thick, arising from a thickened tuber. As in other Avonia species, the stems that carry flower buds grow more or less horizontal, but become erect on the day of flowering and stay that way until the seeds have been dispersed.
The scented flowers are creamy white and appear in late spring and early summer.
There are two subspecies: subsp. papyracea occurs throughout the Little Karoo and is also found in the Great Karoo, whereas subsp. namaensis occurs in southern Namibia, the Richtersveld and Bushmanland. Both subspecies seem to feel most at home amongst white quartz pebbles.
According to the literature the main difference between the two is that in the first one, the edges of the scales are entire (without any teeth or other incisions) and in the second one saw-edged to toothed.
The following pictures show plants of subsp. papyracea.

Anacampseros comptonii (1)

When you have a first look at the kind of habitat this species is found in, it looks bare and desolate.
The photo below was made in the beginning of April after good rains,  so one would expect a lot of activity going on.  And there is, but the plants growing here are so small, that you have to look properly to see them. Accidentally, the other interesting dwarf succulent growing in this spot near Nieuwoudtville is a Conophytum named after the same person  (Prof R.H. Compton, the second director of the National Botanical Gardens in South Africa). More about that at a later stage.

The plants grow in very shallow depressions in flat sandstone rocks. After rains, the depressions are filled with water and the little plants are often completely submerged for some time. The following picture was taken in September.

In the dry period the plants are often almost invisible (the picture below was taken in November). Can you see the little caudexes?

The last picture gives a better idea of how charming these miniatures are when in flower  (the caudexes are only 1-2 cm in diameter and 1-1.5 cm tall) .

Anacampseros albidiflora (1)

Plants of this species are found widespread in the Great and Little Karoo on stony slopes, usually sheltered by rocks or bushes. They are columnar and relatively thick, up to 4 cm tall (when not in flower).
The flowers are white to pale pink and appear mainly from October to January.

Avonia albissima

Even if the name implies otherwise, this is far from the whitest Avonia, as many plants of this species look brownish, rather than bright white (see first picture).
Whatever the colouration, it is a nice little plant which does not get taller than about 4 cm. Sometimes a little caudex is visible (see bottom picture)
The species occurs in Namibia and northwestern South Africa.

Anacampseros arachnoides


It is easy to take this species for granted, even in spite of the cobwebby hairs it is decorated with.
The following is a quote from Gordon Rowley’s booklet ” Anacampseros, Avonia, Grahamia. A grower’s Handbook” :
“This attractive and distinctive species seeds itself freely around the glasshouse and has long been cherished or tolerated in collections of succulents. The abrupt tapering of the leaf to a spiny tip is its most distinctive feature”
This sounds to me like a nice example of damning with faint praise.

When one inspects the plants a bit closer, the beautiful, almost reptile-like surface texture of the leaves is revealed. I must confess that since I have discovered this characteristic, I look at these plants with renewed respect.
