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 …

… 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. 🙂

The last new plants for 2015 …

… are three cuttings of Ceropegia aristolochioides from Isiolo / Kenya and seven rooted cuttings of what I hope will be Ceropegia aristolochioides ssp. deflersiana.

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

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?
