Today …

… was a good day – I found a strinking clone of Ceropegia sandersonii; very large, yellowish flowers with brown markings on the tube.

A new locality for Ceropegia cochleata?

This plant, which in my opinion is Ceropegia cochleata Kidyoo, was photographed in the Phou Khao Khouay National Park in Laos.

This species was so far known only from Thailand, which makes these photos new locality records.

Unwrapping …

… a packet got via ebay, it is supposed to contain a Ceropegia linearis from Malawi (the actual species doesn’t occur there, nor does any of its subspecies …), the picture accompanying the offer showed a Ceropegia linearis ssp. woodii (of the debilis form).

So let’s see what we got there.:

a very small packet …

something from inside … 🙂

Oh see, its neither Ceropegia linearis, nor the plant from the photograph, its just another Ceropegia linearis ssp. woodii clone, but it seems to be one without marbled leaves, that would be nice, let’s see ….

Rediscovery of Ceropegia cycniflora

Ceropegia cycniflora R. A. Dyer – this species was described in the year 1978, however, it was described from old photographies and dried material alone, since the species is known from only three specimens, all collected by the same collector and in the same place, the first in 1936, the other two some years later.

The species was since missing, and some believed it to be extinct (well, at least I did).

~~~

But now, in September 2015, Mr. Alcock discovered a plant that very much resembles what is known as Ceropegia cycniflora … I would call that a rediscovery!

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

see the plant here:

Ceropegia hirsuta Wight & Arnott

Diese Art wurde im Jahr 1834 wissenschaftlich beschrieben, sie ist auf dem Indischen Subkontinent recht weit verbreitet, kommt aber nur in den wärmeren Tieflandregionen vor.

Ceropegia hirsuta gehört zu den Arten mit einer unterirdischen Knolle, sie wächst aufrecht oder kletternd.

Die Blätter sitzen an einem ca. 2 cm langen, kräftig behaarten Stiel, sie sind 4 bis 7 cm lang und 2 bis 3,5 cm breit, elliptisch bis eiförmig, sehr dünn und beiderseits behaart.

Die Blüten entspringen wenig- bis vielblütigen Cymen, sie sind 2,8 bis 5,8 cm lang und sehr auffällig, der untere Teil ist leicht geschwollen, die Blütenröhre hell beige gefärbt und nach oben zu olivbraun oder purpurn gefleckt, die Zipfel sind sehr breit und je nachdem gelblich bis apfelgrün gefärbt. [1][3]

~~~

In Indien ist die Art unter verschiedenen Namen bekannt, Khaloola (in Hindi und in Urdu), Hamana oder Haamana (in Marathi), Khilora (in Rajasthani) und Earragadda (in Telugu), die Knollen werden als Gemüse gegessen. [1]

Bei einigen der Ureinwohner Andhra Pradeshs wird die Pflanze Paamu tiga genannt, auch hier werden die gekochten Knollen gegessen. [6]

Das Volk der Bhilla wiederum, das in einigen Regionen Gujarats, Maharashtras und Rajasthans siedelt, nennt die Art Khutti (in Bhili) und verwendet die Pflanze gegen Magenverstimmungen, wofür vier bis fünf Tage lang einmal täglich frische Knollen gegessen werden. [7][8]

~~~

Im Jahr 2001 wurde Ceropegia hirsuta auch im Nordosten Thailands entdeckt, und zwar im Pha Taem-Nationalpark nahe der Stadt Ubon Ratchthani in der gleichnamigen Provinz, wo die Art in einer Höhe von 250 bis 300 m in laubabwerfenden Dipterocarpaceen-Wäldern auf sandigen Böden wächst. Den Einwohnern dieser Gegend ist die Pflanze schon seit langem bekannt, sie nennen sie Khreua i thao bzw. Kluea li tam und verwenden sämtliche Pflanzenteile als Schmerzmittel. [4][5]

~~~

In Thailand gibt es noch eine zwergwüchsige Form dieser Art, die nur wenige Zentimeter hoch wird und deren Blüten kräftiger weinrot gemustert sind und dadurch fast einheitlich rot wirken – es ist möglich, dass sich hinter dem Namen Ceropegia hirsuta, zumindest in Thailand, verschiedene Arten verbergen.

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

Ceropegia hirsuta Wight & Arnott

This species was scientifically described in the year 1834, it is quite widely distributed on the Indian subcontinent, where it occurs only in the warmer low land regions.

Ceropegia hirsuta is one of the species with an subterranean tuber, it grows upright or climbing.

The leaves sit on a about 2 cm long, heavily hirsute petiole, they are 4 to 7 cm long and 2 to 3,5 cm broad, elliptic to egg-shaped, very thin and hirsute on both sides.

The flowers appear from few- to many-flowered cymes, they are 2,8 to 5,8 cm long and very conspicuous, the lower part is slightly swollen, the flower tube is light beige coloured and speckled olive brown or purple upwardly, the petals are very broad and either yellowish or apple green coloured. [1][3]

~~~

In India the species is known by several names, Khaloola (in Hindi and in Urdu), Hamana or Haamana (in Marathi), Khilora (in Rajasthani), and Erragadda (in Telugu), its tubers are eaten as a vegetable. [1]

Some of the native tribes of Andhra Pradesh call the plant Paamu tiga, also here the boiled tubers are eaten. [6]

The Bhilla tribe again, which settles in some regions of Gujarat, Maharashtra and Rajasthan, calls the species Khutti (in Bhili) and uses the plant as a remedy for stomach upsets, for this purpose fresh tubers are eaten once a day for four or five days. [7][8]

~~~

In the year 2001 Ceropegia hirsuta was also discovered in the north east of Thailand, namely in the Pha Taem National Park near the city of Ubon Ratchathani in the province of the same name, where the species grows at an elevation of 250 to 300 m in deciduous dipterocarp forests on sandy soils. The people in this region of course know the plant for a long time, they call it Khreua i thao resp. Kluea li tam and use all parts of it as an analgesic. [4][5]

~~~

In Thailand exists also a dwarf form of this species, which is only a few centimetres tall and whose flowers are more brightly vinaceous patterned, and which thus appear to be completely red – it is thus quite possible, that behind the name Ceropegia hirsuta, at least in Thailand, distinct species are hidden.
