Re: What's happening to this Gymnocalycium?
This behavior is not uncommon in Gymnocalycium ansitisii. Especially the plants known as G. anisitsii var. multiproliferum sprout very profusely and develop flowers already at young lateral shoots.

Re: 2nd Chinese International Cactus and Succulent Conference
Now I want to read the "Naked thistle and spider cactus - The genus Gymnocalycium", what a fitting title! :mrgreen: That is just a translation of the German title "Nacktdistel und Spinnenkaktus - Die Gattung Gymnocalycium", using two German vernacular names. Mittler, when publis...

Re: 2nd Chinese International Cactus and Succulent Conference
I am still rather surprised that such an "international" event doesn't have a proper website. A website of the conference is here: https://www.23h8.com/25182.html . Many interesting presentations, including the one by Ralph Martin on the Latin names of cacti and succulents. For those of y...

Re: ID for these plants please,would be greatly appreciated
With young plants from large nurseries that you can buy in flower shops or garden centres, it is sometimes difficult to determine the species with certainty: The body and spination are often not yet typically developed and for a sure identification you usually need the flower. In addition, they can ...

Re: ID ideas, please
Dear Ralph,
you are right, Notocactus acutus is classified as a synonym of P. oxycostata. JanD's plant is still young and "well fed", the angular ribs will certainly become more obvious later.

Re: ID ideas, please
The first picture definitely does not show a Gymnocalycium, but a plant from the relationship of Parodia ottonis (Notoactus ottonis). Parodia ottonis sensu lato is a very variable species and many forms have been described as separate species. The plant shown corresponds to Parodia oxycostata (but w...

Re: Ritter's colour descriptions Solved
This already looks good, but here is a scan from the printed copy.There is also this colour wheel. Though it has been blown up from a tiny pic, and I don't think is a reliable guide to the colours! Imagine it brighter.

Re: Ritter's colour descriptions Solved
Ritter used the colour chart of E. Biesalski: "Pflanzenfarben-Atlas", which was published in 1957. The colour chart is based on the German standard DIN 6164. Unfortunately it is no longer available. I got my copy many years ago from an old cactus friend. Once it was offered by Schwarz, but...
