I forgot to …

… take photos from the unboxing, but here is the plant, however.:

It’s a Ceropegia linearis ssp. woodii of course, but it is one with a known locality; it comes from Soutpansberg in South Africa.

I may already own the smae clone, but … one can never have to many Ceropegias.

Ceropegia kituloensis Masinde & F. Albers

Diese Art, die ausschließlich auf dem Kitulo-Plateau in Tansania wächst, wurde im Jahr 2000 beschrieben. [1][2]

~~~

Die Pflanze wächst aufrecht, der Trieb, der eine ca. 1 cm großen Knolle entspringt, wird 7 bis 18 cm hoch.

Die Blätter, 0,1 bis 0,2 cm lang gestielt, sind ei-lanzettförmig bis schmal elliptisch, etwa 1,2 bis 3 cm lang, 0,3 bis 0,9 cm breit und mehr oder weniger flaumig behaart.

Die Blüten sind bis zu 3,8 cm lang und vornehmlich grünlich gefärbt. [2]

~~~

Die Art ist angeblich sehr nah mit Ceropegia achtenii De Wild verwandt. [2]

Ceropegia kituloensis Masinde & F. Albers

This species, which exclusively grows on the Kitulo Plateau in Tansania, was described in the year 2000. [1][2]

~~~

The plant grows upright, the stem, which is born from an about 1 cm large tuber, is 7 to 18 cm tall.

The leaves, with a 0,1 to 0,2 cm long petiole, are egg-lancet-shaped to narrowly elliptic, about 1,2 to 3 cm long, 0,3 to 0,9 cm wide and more or less tomentosely haired.

The flowers are up to 3,8 cm long and primarily greenish in colour. [2]

~~~

The species is reportedly very closely related to Ceropegia achtenii De Wild. [2]

Unboxing …

This time I ordered plants from the Röhner-Versand, for the first time.

Here we go.:

the packet … quite big

lots of styrofoam flakes and a leaf looking out … in fact I’m very happy with these flakes, cause I really need them for draining the plant pots   🙂

the plants, each wrapped in paper and wrapped up again in a paper bag, fine …   🙂

here they are: Ceropegia ballyana (my very first one), Ceropegia radicans, and Ceropegia variegata, the plants are very healthy and quite large, this is indeed a good bargain

What a fine day!   😛

Interactions with animals

It is well known that Ceropegia spp. are pollinated by small to very small flies from several families, so it is not really a surprise to find predatory invertebrates like spiders at the flowers or near the flowers.

One such example can be found on page 14 in P. G. Archer’s ‘Kenya Ceropegia Scrapbook’ from 1992, where a crab spider is photographed sitting very prominently close to a flower of a Ceropegia abyssinica Decne. ready for action.

~~~

When Prof. J. Ollerton, who investigates pollinators and pollinator-plant-interactions in great detail, dissected flowers of ca. 50 years old herbarium specimens of Ceropegia nilotica Kotschy, he did not only found dried flies on occasion but discovered in one of the flowers two (unidentified) ants – caught in the act; one of them still had a part of a fly wing in its mouth parts, meaning it has been collected and preserved in the act of eating one of the probable pollinators!

Well, this is obviously still the only known case of ants eating flies inside a Ceropegia flower so far, I personally do not know of any other one.

But of course it leads to several questions:

Does that occur more often?
Does that occur all over Ceropegia’s range?
Which ant species are involved?

… and so on ….

~~~

BTW: According to a very recent study, Ceropegia nilotica mostly attracts flies from the genus Desmometopa, so-called freeloader flies (family Milichiidae), and from the genus Forcipomyia, biting midges (family Ceratopogonidae). [2]

… more of that is coming soon ….

Ceropegia speciosa H. Huber

Diese Art ist eine bis zu 2 m groß werdende Kletterpflanze mit relativ großen Blättern.

Die Blüten sind ebenfalls recht groß und ähneln in ihrer Form ein wenig den Blüten von Ceropegia haygarthii Schltr. oder Ceropegia rhynchantha Schltr..

~~~

In Malawi ist die Art vom Mount Mchese bekannt, in Tansania findet man sie in den Kiboriani-Mountains. In Sambia wächst die Art in Galeriewäldern, die von Arten wie Brachystegia spiciformis Benth., Craterispermum schweinfurthii Hiern, Englerophyton magalismontanum (Sond.) Heine & J. H. Hemsl., Thunbergia petersiana Lindau, Uapaca lissopyrena Radcl.-Sm. und Uapaca sansibarica Pax dominiert werden.

Ceropegia speciosa H. Huber

This species is an up to 2 m tall climbing plant with relatively large leaves.

The flowers are quite large too and are somewhat similar in shape to the flowers of Ceropegia haygarthii Schltr. or Ceropegia rhynchantha Schltr..

~~~

In Malawi the species is known from Mount Mchese, in Tanzania it is found in the Kiboriani Mountains. In Zambia, the species grows within gallery forests dominated by species like Brachystegia spiciformis Benth., Craterispermum schweinfurthii Hiern, Englerophyton magalismontanum (Sond.) Heine & J. H. Hemsl., Thunbergia petersiana Lindau, Uapaca lissopyrena Radcl.-Sm. and Uapaca sansibarica Pax.
