Ceropegia convolvuloides A. Rich.

Diese nahezu unbekannte und kaum erforschte Art, die im Jahr 1851 beschrieben wurde, ist offenbar in der Region des ‘Horns von Afrika’ endemisch, wo man sie aus Äthiopien und dem Nachbarland Eritrea kennt.

Einige der lokalen Namen in Äthiopien lauten Merokoua oder Merokua bzw. Shabina (in Aari), Teile der Pflanze werden gegessen. [1][2]

~~~

Die Triebe der wüchsigen, windenden Kletterpflanze sind behaart.

Die Blätter ähneln denen von Winden (daher auch der Artname) und ebenfalls behaart. [3]

~~~

Die Art gehört sehr wahrscheinlich zum Verwandtschaftskreis vom Ceropegia abyssinica Decne. und Ceropegia nigra N. E. Br., hat aber auch einiges mit den arabischen Arten Ceropegia foliosa Bruyns und Ceropegia sepium Deflers gemein. [3]

Ceropegia convolvuloides A. Rich.

This almost unknown and rather un-researched species, which was described in the year 1851, is obvioulsy endemic to the ‘Horn of Africa’ region, where it is known from Ethiopia and from the neighboring Eritrea.

Some of the local names in Ethiopia are Merokoua or Merokua resp. Shabina (in Aari), various parts of the plant are consumed. [1][2]

~~~

The stems of this fast-growing, twining climber are hirsute.

The leaves resemble those of bindweed (thus its species epithet) and are likewise hirsute. [3]

~~~

This species very probably belongs to the species group amongst Ceropegia abyssinica Decne. and Ceropegia nigra N. E. Br., however, it also has some affinities to the Arabian Ceropegia foliosa Bruyns and Ceropegia sepium Deflers. [3]

What will happen in 2017?

Well, not much … however, the species descriptions will appear two times within a month, one at the first, the other one at the 15th or so, so there will be 24 species descriptions altogether in the next year.

I’m still very busy with my schooling, but have my exams this year, and hopefully I may find more time then to do some drawings etc..

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.
