Ceropegia aristolochioides Decne.

Ceropegia aristolochioides Decne.

Diese wundervolle Art wurde im Jahr 1838 beschrieben, sie ist vermutlich ein Artenkomplex. [3][12]

~~~

Verschiedene Formen, die ehemals als eigene Arten oder Unterarten galten, werden heute, auf Grund von DNA-Untersuchungen, in die Art eingegliedert (zum Beispiel: Ceropegia albertina S. Moore, Ceropegia beccariana Martelli, Ceropegia maasaiorum Halda & Prokes und Ceropegia seticorona E. A. Bruce). [11]

~~~

In ihrer Heimat findet man diese Art vor allem im Buschland, dort klettert sie zwischen der umgebenden Vegetation und erreicht dabei einige Meter an Höhe.

Die Blätter sind gewöhnlich hübsch herzförmig und frischgrün, die Blüten, die nach verrottendem Obst riechen, sind rot, rotbraun oder gelb (je nach Herkunft der Pflanze) und heben sich vom Laub wunderbar ab.

~~~

In Westafrika findet die Art auch als Arzneipflanze Verwendung.

Verschiedene afrikanische Namen sind unter anderem Uluku mbiré, Ulu n’dioloko miyé, Ulu ndĭolond missé oder Ulundoloko missé (bei den Bambara, unter anderem in Mali und im Senegal); Waski (bei den Hausa im Niger); Galétar, Labtar (bei den Ndoute oder Ndut); Dagga filoré, Tudil, Todi (bei den Peuhl im Niger); Agga (bei den Tamacheck im Niger) oder Kubudighi (bei den Zarma im Niger). [5][13]

Im Tschad wird die Art Shader Tén genannt, in Äthiopien Mororo (in Somali) bzw. Schamígge (in Tigre). [1]

~~~

Ceropegia aristolochioides  ssp. deflersiana Bruyns

Diese Unterart kommt ausschließlich auf der arabischen Halbinsel vor, sie unterscheidet sich von der Nominatform vor allem durch ihr behaartes Karpell (Fruchtblatt). [11][12]

Die Pflanzen erreichen Größen von mehr als 5 m, ihre Blätter sind oft kleiner als die der Nominatform.

Die Form und auch die Färbung der Blüten variiert enorm, je nachdem aus welcher Gegend die Pflanze stammt, können die Blüten rot, rotweiß, weiß aber auch gelb oder grün gefärbt sein. [6][9][11][12]

~~~

Im Jemen findet man die Pflanze an vegetationsreichen Hängen, die mit zahlreichen anderen sukkulenten Pflanzenarten bewachsen sind, darunter auch viele Arten, die man in Europa in den Sammlungen der Sukkulentenliebhaber finden kann, z.B. Adenium obesum (Forssk.) Roem. & Schult., Aloe sabaea Schweinf., Cissus quadrangularis L., Dorstenia foetida (Forssk.) Schweinf., Euphorbia inarticulata Schweinf., Euphorbia schimperi C. Presl und Sanseviera ehrenbergii Schweinf. ex Baker. [7]

~~~

In Saudi Arabien wird die Pflanze Ghashwa genannt, ein Name, den sie mit weiteren Vertretern der Gattung teilt.

Eine Form, die im Wadi Jowah Amra gefunden wurde, trägt Blüten, die denen der Ceropegia arabica var. abbreviata Bruyns täuschend ähnlich sehen, eine weitere, besonders prächtig blühende Form kommt im Wadi Sakhara vor, als eine der am weitesten nördlich verbreiteten Ceropegia-Formen überhaupt. [6][9]

~~~

Diese Form ist durchaus in Kultur, aufgrund ihrer Variabilität aber sicher meist unerkannt.

~~~~~~~~~~~~~~~~~~~~~

Ceropegia aristolochioides Decne.

This beautiful species was decribed in the year 1838, it may in fact be a species complex. [3][12]

~~~

Several forms, which were originally described as distinct species or subspecies, are now, based on DNA studies, included in this very variable species (for example: Ceropegia albertina S. Moore, Ceropegia beccariana Martelli, Ceropegia maasaiorum Halda & Prokes, and Ceropegia seticorona E. A. Bruce). [11]

~~~

In the wild this species is commonly found in bushland, where it climbs among the surrounding vegetation and sometimes reaches several metres in length.

The leaves are usually pretty heart-shaped and bright green, the flowers, which smell like rotting fruits, are red, reddish brown or yellow (depending on the origin of the plant) and are a very nice contrast to the leaves.

~~~

In West Africa this species is also used as a medical plant.

Some african names, among others, are Uluku mbiré, Ulu n’dioloko miyé, Ulu ndĭolond missé or Ulundoloko missé (by the Bambara, incl. those in Mali and in the Senegal); Waski (by the Hausa in Niger); Galétar, Labtar (by the Ndoute or Ndut); Dagga filoré, Tudil, Todi (by the Peuhl in Niger), Agga (by the Tamacheck in Niger) or Kubudighi (by the Zarma in Niger). [5][13]

In Chad the species is named as Shader Tén, in Ethiopia as Mororo (in Somali) resp. Schamígge (in Tigre). [1]

~~~

Ceropegia aristolochioides  ssp. deflersiana Bruyns

This subspecies is strictly restricted the Arabian Peninsula, it can be distinguished from the nominate race particularly by its hairy carpel (female reproductive unit). [11][12]

The plants reach sizes of more than 5 m, the leaves are often smaller than those of the nominate form.

The form and colouration of the flowers is highly variable, depending on the origin of the plant the flowers can be coloured in red, red and white, white, as well as yellow or green. [6][9][11][12]

~~~

In the Yemen this plant can be found at vegetation-rich slopes, that are covered by numerous other succulent plant species, among them also many species, which can be found in Europe in the collections of succulent lovers, for example Adenium obesum (Forssk.) Roem. & Schult., Aloe sabaea Schweinf., Cissus quadrangularis L., Dorstenia foetida (Forssk.) Schweinf., Euphorbia inarticulata Schweinf., Euphorbia schimperi C. Presl and Sanseviera ehrenbergii Schweinf. ex Baker. [7]

~~~

In Saudi Arabia the plant is named as Ghashwa, a name that it shares with other members of the genus.

A form, that was found in the Wadi Jowah Amra, has flowers, which are deceptively similar to that of Ceropegia arabica var. abbreviata Bruyns, another form with exceptionally gorgeous flowers occurs in the Wadi Sakhara, as one of the furthest northerly occurring Ceropegia forms at all. [6][9]

~~~

This form is very well in cultivation, due to ist variability probably often undetected.

Two for the price of one ….

Two for the price of one ….

Well I was wondering about the flowers of my Ceropegia aristolochioides ssp. deflersiana, which suddenly looked quite different from the first one, yet I just recognized that I obviously have at least two different clones of that plant – bought all together.

See.:

The two grow together, and because of the mass of stems I have no idea who is who.   😦

already flowering …

already flowering …

… here’s the first flower of what I bought as Ceropegia aristolochioides ssp. deflersiana

… we’ll see what it turns out to be 🙂

c.a.deflersiana.291115.1

*********************

add.: The flower dropped today – and indeed, the carpellum is haired, there’s a very, very fine kind of fur covering the carpellum! This can be seen with the naked eye when holding the plant against the light.

So, this is in fact the Arabian subspecies. 🙂

Ceropegia aristolochioides ssp. deflersiana x rupicola

Ceropegia aristolochioides ssp. deflersiana x rupicola

Diese schöne Form wurde im Jahr 1980 anhand von Pflanzen als neue Varietät beschrieben, die nahe der Stadt Al Qa’idah und einem benachbarten Ort im Gouvernement Ibb im Jemen gefunden wurden.

Sie unterscheidet sich von der Normalform durch ihre Blüten, die größere Öffnungen haben und eine behaarte Innenseite (ein Merkmal, das bei der gewöhnlichen Form unbekannt ist). [1]

~~~

Diese Form ist entweder tatsächlich eine Varietät oder ein Naturhybrid mit Ceropegia aristolochioides ssp. deflersiana Bruyns. Solche Hybriden finden sich auch in Kultur, allerdings ist oft unklar ob es sich hierbei um Pflanzen der selben Herkunft handelt oder um Hybriden mit der afrikanischen Nominatform der Ceropegia aristolochioides Decne., die spontan in Kultur entstanden sind. [2]

~~~

Das Foto zeigt eine kultivierte Pflanze, sehr wahrscheinlich der echten jemenitischen Form.

~~~~~~~~~~~~~~~~~~~~~

Ceropegia aristolochioides ssp. deflersiana x rupicola

This beautiful form was described as a new variety in the year 1980 on the basis of plants that were found near the city of Al Qa’idah and in another nearby locality in the Ibb Governorate of the Yemen.

It differs from the common form in its flowers, which have larger openings and which are covered with hairs on the inner surface (a feature that is not known in the common form). [1]

~~~

This form is now either a variety or rather a naturally occurring hybrid with Ceropegia aristolochioides ssp. deflersiana Bruyns. Such hybrids are in fact known in cultivation too, however, it seems not to be known if they are of the same origin, or if they rather represent hybrids with the African nominate race of Ceropegia aristolochioides Decne., appeared spontaneously in cultivation. [2]

~~~

The photograph shows a cultivated plant that may very well be the actual Yemenite form.

The Wadi Al-Uss enigma

The Wadi Al-Uss enigma

There are so many forms of both subspecies of Ceropegia aristolochioides, that it seems almost impossible to say to which subspecies the particular forms belong.

I’d like to find out if the plants, filed as Ceropegia aristolochioides ssp. deflersiana, are in fact what they are supposed to be.

It is not possible to recognize the affiliation to one of the subspecies from any external part of the plant beside the carpel of the flower, this is glabrous in the nominate subspecies, but hirsute in the ssp. deflersiana. The form of the flower may be somewhat narrower in the arabian subspecies, but this is by far not always the case, the same can be said about the colouration, the colour of the flower doesn’t mean a thing.

There is a clone in trade, which is named Wadi Al-Uss (in variant forms of spelling), the sad thing is, there are two completely different plants to be found by that name (you can see both of them pictured below).

One has narrow, yellowish flowers and belongs indeed most probably to the ssp. deflersiana, as it is almost identical to a clone from a place named Al-Qaidah in the Yemen (Miroslav Řičánek; Pavel Hanáček: Some notes on the succulent Asclepiadaceae of Yemen. Asklepios 74: 7-12, 1998).

The other one is more like a typical plant from the nominate ssp., but may in fact also belong to the arabian subspecies. It can, however, – oh no, please kill me – also be found labeled as Ceropegia aristolochioides, the nominate race.

As I mentioned before, both clones can be found under the name ‘Wadi Al-Uss’ – so who is who?
