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.   😦

Better late than never …

My Ceropegia aristolochioides from Isiolo / Kenya has now (!!!) started to grow, almost 9 months after I bought the cutting, unbelievable.

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 🙂

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

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.

Natural enemies

Most, if not all species of the genus Ceropegia contain larger or smaller amounts of the alkaloid Ceropegin, and thus are probably not specifically taken by mammals as food, however, giraffes have been observed in the Niger to occasionally eat shoots of Ceropegia aristolochioides. [5]

~~~

On the other hand, however, several species of Ceropegia are very important food plants for the caterpillars of some butterfly species from the Brush-footed Butterfly family (Nymphalidae).

The caterpillars of the Common Tiger (Danaus genutia (Cramer)) from India feed on Ceropegia elegans, Ceropegia intermedia, Ceropegia lawii, Ceropegia manoharii, Ceropegia oculata, and Ceropegia thwaitesii. [1][6][9]

The caterpillars of the Glassy Tiger (Parantica aglea (Stoll)) have been recorded from the Andaman Islands to feed on Ceropegia andamanica, and from India on Ceropegia bulbosa, Ceropegia hirsuta, Ceropegia lawii, and Ceropegia oculata. [2][6][9][10]

The caterpillars of the Ceylon Tiger (Parantica taprobana (Felder & Felder)) from Sri Lanka are thought to feed on Ceropegia thwaitesii, however, this is still to be proven. [8]

The caterpillars of the African Monarch (Danaus chrysippus L.), a species that is distributed over Africa and parts of Asia, are known to feed on several species of Ceropegia in Africa, and at least on Ceropegia bulbosa in India. [2]

The same species was formerly a straggler to the Canary Islands but is now a resident, its larvae were recorded on the islands first on the introduced asclepioid species Orbea variegata (L.) Haw. in 2010. [7]

This species is now known to feed on the endemic Ceropegia species as well (see photograph, which, by the way, was taken in 2008 (!)).

Ceropegia aristolochioides

This is one of many flowers, that appeared this year on one of my two plants for the first time – similar flowers can be seen on several pictures in the internet, named as Ceropegia aristolochioides, or Ceropegia aristolochioides ssp. deflersiana.

As far as I can see (using my weak eyes) the carpel is glabrous, thus this particular plant should be of the nominate race.
