Drosanthemum delicatulum

It would be difficult to come up with a more apt name for this plant, which grows into a shrublet up to about 20 cm tall and to 25 cm in diameter with small leaves (2-4 mm long and 2-2.5 mm thick) covered in globose papillae (longer at the base).
The white or pale pink flowers are only 8-10 mm in diameter, without or with very short stalks, and are present in October-November.

Growing on sand and shale slopes -with or without quartz- in the Montagu, Ladismith, Swellendam area.

Cleretum (papulosum ssp.) schlechteri

These small annual plants have up to 6 cm long, strap to racket-shaped leaves which are covered with glistening bladder cells.
The yellow flowers have long stalks and are relatively large (about 4 cm in diameter); they appear in July-October.

Usually found in disturbed, sandy places from Springbok to Kamieskroon en Nieuwoudtville. Photos taken 8 August 2018 just north of Gifberg.

Glottiphyllum regium (part 1 of 2)

This is the largest species of the genus (regium = royal), forming robust compact clumps up to 15 cm across.
The leaves are decussate  (arranged in a cross), longer than 6.5 cm (up to 13 cm) and 2 cm wide, three-angled in cross-section to more or less cylindrical. They have a sharp upright point and are slightly unequal, narrowed below and ranging in colour from bright green and grey-green to ochre.
The flowers have long stalks (longer than 3 cm), are up to 3.5 cm across and appear from June to December. After flowering, the fruits remain on the plants.

Although the species is locally abundant, it only occurs in a handful of sites near Calitzdorp, on sandstone slopes and sandy-loamy soils. It is therefore categorized as endangered.

In G.  surrectum the leaves are similar in shape, but shorter than 6 cm.
G. cruciatum is similar in general appearance, but has leaves with an expanded base.

Stayneria neilii

Oddly enough, even though this species belongs to the giants in the family, it is easy to overlook the plants when not in flower, because they usually occur among other plants that are about as tall or even taller.

They form stout erect shrubs up to 1.5 m tall, with light to dark green leaves, which are to 8 cm long and 8 mm wide, three-sided with a sharp edge at the bottom.
The flowers have white or pink petals and appear in winter and early spring (July-September), usually in groups of three to seven on a short stalk; they are to 4 cm in diameter and often look untidy.
The fruits have 6-9 compartments (usually 8); once opened they do not completely close anymore.

This is the only one species in the genus and has not been recorded from outside the Breede River Valley in the Western Cape, where it occurs on clay slopes and acid sandstone soil between Worcester and McGregor. The rainfall here is 300-400 mm per year, mainly in winter.

Delosperma crassum

Both the current name and its synonym D. robustum refer to the unusually sturdy appearance of this species compared to other Delospermas.

The plants form erect shrubs up to 30 cm tall, with a basal stem up to 4.5 cm in diameter. They have yellowish brown branches, which are covered in small papillae when young.
The leaves are erect to spreading, more or less round in cross-section, 1.5-2.5 cm long and up to 3 mm thick, bright green and velvety.
In July-August the mainly straw-coloured flowers appear; they are solitary and up to 2.5 cm in diameter, with a few staminodes (yellow with a white base) .

The distribution area is from Kamieskroon to Vredenburg and the plants are found on stony ground.
Pictures were taken earlier this month on the Knersvlakte.

 

Gibbaeum pilosulum

Although in  several species of Gibbaeums the leaves have a velvety  cover, G. pilosulum is the only one with long, erect hairs. Apart from this, the species is very similar to G. nuciforme, which sometimes grows  less than a kilometre away.

The plants form compact mats to 13 cm in diameter, embedded in the ground. There are up to 10 leaf pairs, which are united and form egg-shaped, green to yellowish green bodies 0.5- 2 cm across with a short fissure at the tip.
The flowers are 1.2 – 1.6 cm in diameter and bright pink to purple; they appear in July-August.

Found in the western Little Karoo (Ladismith-Barrydale area), usually in quartz patches together with G. heathii.

 

 

Delosperma peersii

Plants of this species form small shrubs up to 50 cm tall with bright green leaves which are triangular in cross section and  about 1.5 cm long, spreading with a reddish, recurved tip.
The flowers are 1.5-2 cm in diameter, white to pink, often with 3 together; they appear from spring to summer.

The species does not occur in many places,  but is sometimes abundant in loamy soils from just west of Oudtshoorn to Willowmore.
The last picture was taken on the back road from Montagu and Anysberg. It seems to me that the plants in this population have all the typical characteristics of D. peersii, so the species may be more widely distributed than is recorded.

Brianhuntleya purpureostyla

These plants are either tufted or forming long runners.
The trigonous leaves are 3-6.5 cm long and their margins and keel have tiny teeth near the tip.
In June-July the flowers appear; they are solitary, about 3 cm in diameter, on 2-4 cm long stalks; the petals are pink to white with pinkish-purple central vein and sides.
As in the other two species in the genus (see also B. intrusa), the flowers turn into almost globular tumble fruits, lying on the ground and facing upwards.
The plants occur on stony slopes in the area between McGregor, Swellendam and Montagu.

Since its description as a Mesembryanthemum in 1920, the species has been placed in Erepsia, Ruschia, Acrodon and Cerochlamys.
If you are interested in the vagaries of its taxonomic history, search the Web for “A Gordion knot in Ruschioideae (Aizoaceae): Acrodon and Brianhuntleya in an attempt to disentangle the confusion” by Heidrun Hartmann and Ingeborg Niesler in Bradleya 30/2012, p. 33-60.

Antimima solida

The first name that comes to mind on seeing a plant of this species is probably Argyroderma fissum (unless you are a real expert of course).
The two species share the same growth form as well as size and shape of the leaves; often they also grow near to each other. Fortunately the fruits are rather different and stay on the plants for a long time. (The Antimima has fruits with 5 locules, whereas in Argyroderma fruits there are at least 10 compartments).
The finger-shaped leaves are up to 3 cm long. The flowers come mostly in threes and appear in May-July; they are pinkish-purple and 1.8-2.5 cm in diameter.

In some places the species forms large mats on flats or gentle loamy slopes with an open cover of quartz pebbles. According to the literature, it occurs in the Vredendal-Vanrhynsdorp area, but last year I also found plants in the northern half of the Knersvlakte.


Glottiphyllum suave

These compact plants rarely have more than 3 branches, each usually with two leaf-pairs.
The leaves are opposite and have sharp margins; they are thickened below, but without a hump.
Suavis means fragrant, referring to the nicely scented flowers, which are about 3 cm in diameter and appear in April-May.
Occurring on quartz and/or shaly sandstone in the western Little Karoo and the Laingsburg area.
The plants are similar to G. linguiforme, but with thicker leaves.
