Ceropegia occulta R. A. Dyer

Diese Art wurde im Jahr 1958 beschrieben, sie bewohnt ein sehr kleines Areal in der Westkapprovinz, wo man sie gelegentlich zusammen mit der sehr viel weiter verbreiteten Ceropegia africana R. Br. antrifft. [1][3]

~~~

Ceropegia occulta scheint, oberflächlich betrachtet, sehr nah mit dem Ceropegia africana / linearis-Komplex verwandt zu sein, meiner Meinung nach ist sie dies aber nicht. [3][4]

~~~

In freier Wildbahn ist die Art in den heißesten Gegenden zu finden, wo sie zusammen mit Crassula rupestris Thunb. und Stapeliopsis saxatilis (N. E. Br.) Bruyns wächst. [3]

Die Art formt Teppiche aus dem Boden anliegenden Trieben mit unzähligen unterirdischen Knollen. Die Triebe haben eine gräuliche Färbung. Sie richten sich willkürlich vom Boden auf, erreichen aber selten mehr als 8 cm Länge.

Die Blätter sind klein, dick, lanzettförmig und spitz zulaufend.

Die Blüten erscheinen in einblütigen Cymen an sehr langen Pedunkeln, sie sind innen weißlich, außen rosabraun gefärbt und etwas dunkler gestreift. Die olivgrünen bis schokoladenbraun gefärbten Petalen formen eine Art Pagodendach. Sie riechen, im Gegensatz zu den Blüten der Arten des Ceropegia africana / linearis-Komplexes, wie Wachsmalstifte. [3][4]

Ceropegia occulta R. A. Dyer

This species was described in the year 1958, it inhabits a very small area in the Western Cape Province, where it sometimes can be found growing together with the much more widespread Ceropegia africana R. Br.. [1][3]

~~~

Ceropegia occulta, at first appearance, seems to be very closely related to the Ceropegia africana / linearis complex, but in my opinion, it isn’t. [3][4]

~~~

In the wild, the species is frequently found in the hottest places, growing together with Crassula rupestris Thunb. and Stapeliopsis saxatilis (N. E. Br.) Bruyns. [3]

The species forms carpets of stems, clung to the ground, with lots of small underground tubers. The stems have a greyish brown color. They randomly protrude from the ground whereby they seldom exceed 8 cm in length.

The leaves are small, thick, lancet-shaped and apically pointed.

The flowers appear in one-flowered cymes on very long peduncles, they are whitish colored inside, brownish pink outside, somewhat darker striped. The olive green to chocolate-brown colored petals form a kind of pagoda roof. They small, unlike the flowers of the species from the Ceropegia africana / linearis complex, like wax pencils. [3][4]

Landscaping with Ceropegia occulta

Landscaping with Ceropegia occulta

In the wild, Ceropegia occulata grows amongst so called Witteberg quartzite, which led to the plant being named locally as the “rock-hugging Ceropegia”.

I do not have an idea what exactly Witteberg quartzite are, but they obviously look quite like the stones that I have found around someone’s house.

Here is the supposed ‘landscape’, and one of the Ceropegia occulta next to it.

Here is the final ‘landscape’, well it’s just a planted pot with three stones after all ….   

The tubers and some cuttings, just stuck into the soil, I hope they will root.

Spring

Spring

Bit by bit the first flowers open now.

The first one (it actually didn’t really stop flowering over the winter) is Ceropegia occulta, whose small flowers amazingly smell more or less exactly like wax crayons.

The second one is Ceropegia inornata, also here I do not count the flowers, that appeared during the last two or three months. Therefore this flower from today is the first one for 2011.
