Another (definitely) new Ceropegia from Thailand = Ceropegia cochleata Kidyoo

Another very strinking plant was found and photographed by Rapeepattadha Chamwong in the Phu Kradueng National Park in the Loei Province of Thailand.

At first glance I thought it to be identical with the plant tag-named by me as Ceropegia sp. ‘Sai Thong’ posted here at 25. January 2011:

But I recognized some differences, which may more or less important.:

The shape of the leaves isn’t the same in both plants, but this may not be of taxonomic interest. The flower differs in it’s shape and colouration, again this may not be of great taxonomic importance.

But, the plant photographed in the Phu Kradueng National Park seems to have only a very short peduncle or even no peduncle at all (Ceropegia sp. ‘Sai Thong’ has a quite large one, as can be seen in the photograph), furthermore the flowers seem to appear singly (whereas they appear in small groups in Ceropegia sp. ‘Sai Thong’), and I’m quite sure that these two facts may indeed be of some interest for an taxonomist!

Anyway, this one also seems to be a distinct and up to now undescribed species!

See a photograph of this very attractive plant here:

Ceropegia bhatii S. R. Yadav & Shendage

This species was first discovered in the year 2008 and has been described in 2010.

It is a twining species, which is in some aspects somewhat similar to both Ceropegia attenuata Hook. as well as to Ceropegia noorjahaniae M. A. Ansari.

The stem reaches only 0,1 to 0,2 in diameter and grows out of an small subterranean tuber, which has a size of 2 to 2,5 cm in diameter. It grows twining and reaches a length of about 1 m.

The leaves are narrow lancet-shaped, 4,5 to 9 cm long and 0,4 to 1,5 cm wide, they sit on an 0,5 to 0,8 cm long petiole.

The about 4 cm long flowers of this species resemble those of Ceropegia noorjahaniae, but are narrower and have proportionally longer corolla lobes. They appear in two-flowered cymes, which are born between the leaf axills on the upper part of the stem. The flowers are completely yellowish green on the outside, on the inside they are speckled with purplish red spots.

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

The species’ range of distribution is, as known up to now, limited to an only 5 km² large area, which harbours a population of only thirty-five individuals. Ceropegia bhatii is therefore one of those species which are acutely threatened with extinction, a fate that it shares with many other indian members of its genus.

The first new addition to my collection in 2011

And this is Ceropegia albisepta, bought today as Ceropegia succulenta.

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

This is a clone from Kenya, as far as I know.

I wonder how this plant will look in, let’s say, two months or so. 😛

This plant actually turned out to be a misnamed Ceropegia sandersonii x something clone.
