I can't see anywhere for the flies to get in so I am assuming another couple of days to open up. I would expect it to be a lot more open and bigger when it does open.

I assume this is what was Ceropegia smithii, now called Ceropegia radicans subsp. smithii? Presumably "smidtii" occurred after it passed though the hands of an Afrikaans or Dutch speaker.

The dried, pressed flowers on the type specimen are about 4½ cm long.

There appear to be some who think it is a natural hybrid between Ceropegia sandersonii and Ceropegia radicans.

The two species don't seem to share a location, as far as I can see. Ceropegia sandersonii is to the north and Ceropegia radicans to the south. Ceropegia radicans subsp. smithii is even further south, not between the other two populations as you might expect from a natural hybrid.

Lovely.

That does not look at all like your own photos of a definite Ceropegia radicans subsp. smithii. viewtopic.php?f=1&t=161514&p=227090&hil ... ns#p227091

So, I would assume that some grower decided that the assumption that Ceropegia radicans subsp. smithii is a hybrid between Ceropegia sandersonii and Ceropegia radicans was true and that conversely, knowing that this plant is one of the many hybrids between Ceropegia sandersonii and Ceropegia radicans made since at least 1908*†, they could call it Ceropegia smidtii.

It looks quite similar to the hybrid Chris Moore had as Ceropegia sandersonii hybrid "Mars". Presumably, they didn't have the peppermint Aero when it was named.
https://www.asclepiad-exhibition.org/Ceropegia_r-s.htm
http://www.flores-reinecke.de/Pflanzens ... a_o-z.html

These hybrids are also in collections as Ceropegia x rothii. Ralph noted the similarity in that other thread. Named after Dr P. Roth who made that first artificial cross in 1908.

"Bowl with Ceropegia radicans, behind it two pots with C. Sandersoni X radicans. Original recording for the "Garden World"." Not a close-up picture, unfortunately.
An artificial cross, C. Sandersoni, fertilized with pollen from C. radicans, however, had success. This is the first successful intended cross in the case of Ceropegia (illustration opposite).

The seedlings that are more of the mother plant, so C. Sandersoni, who were similar, evolved in the in the first year and bloomed in the second.

As is often the case with hybrids, the plants are comes, harder, more vigorous and more willing to flower than the parents. They were potted in the greenhouse for a year several meters long and bloomed profusely. Already in May, in planted in a sheltered, sunny location outdoors, bloomed they developed here almost richer than the potted plants but much fewer leaves, or threw them off again and also remained considerably shorter in growth. The strong winds thin stems bear about 3 cm long, 1.5 cm wide, thick-fleshy, oval-lanceolate leaves, the flowers are mostly closed 3 and 4 on a short handle. The flower is about 5 to 6 cm long, the tube light green, striped a little darker, the funnel-shaped extension also light green with olive-colored spots; the tips that are connected at the top are at the top folded up, yellow-green with shiny emerald-green spots mackerel, the outer corona is yellow with five flat, loaded eyelashed tips, the five croissants white, dark at the bottom red. This hybrid has met with a wide range of interest was published by Prof. Gurke in the "Monthly for Cactus Kind ", No. 1, 1911, and baptized C. Rothii Gurke.

I have this interesting bastard on several Germans and some foreign botanical gardens given, too Haage & Schmidt in Erfurt, and believe that the hard, fast-growing and flowering plant will soon find friends.

A few years ago it was in the botanical garden in Leiden as a chance product a hybrid of C Sandersoni as mother and C similis emerged as the father, which was developed by N. E. Brown in "Gard. Chron. "Described in 1906 as C. hybrida N. E. Br and was named by W. Herter C. Meyeri-Arthuri.

If C. Rothii and C. Meyeri-Arthuri also have the same mother, so they are quite different in shape and appearance, while the flowers are more similar in shape have, but are also different in color.
† The original description as Ceropegia Rothii:
https://www.biodiversitylibrary.org/ite ... 0/mode/1up
The plant was created by Dr. P. ROTH in Bernburg, a very eager and successful breeder of Cacti and other succulents. He had Ceropegia in 1908 Sandersoni J.D. Hook, with the pollen from C. radicans Schlechter fertilized with success and bred a number of seedlings. The Plants are extremely vigorous and develop outdoors planted out very well in full sun. Dr. ROTH has it already to several botanical gardens in Germany and England and also sent to commercial nurseries, and certainly will pretty, fast-growing and very blooming plant soon to be friends find.
