Rebutia/Aylostera talk.

[DaveW]

Will not affect those in the UK, but the notice of Ralph's talk says GMT. We have put our clocks forward an hour to British Summer Time = BST so evidently the notice was written before then. Just checked with Nigel in charge of talks and it should be 7.30pm BST for those abroad calculating the time for their time zones.

Ralph in his talk had a guess at what the Rebutia archibuiningiana name meant. The botanical definition is:-

"In biology and anatomy, it usually means "primitive", "original", or "ancestral"1. For example, archipterygium means "primitive fin or wing".

From Wikipedia

"The name R. buiningiana was gradually used to designate two completely different plants. At first, this name was proposed by F. Ritter for his find from the vicinity of Padcaya (Bolivia, department of Tarija), but the name was not validly published. Therefore, after W. Rausch validly described his plant under the same name, F. Ritter changed the name of his find to R. archibuiningiana (in the sense of old, original buiningiana)."

Rausch published R. buiningiana in Kakteen Sukkulentum in 1972 and Ritter validly published his R. archibuiningiana in Ashingtonia in 1978.

Ralph jokingly mentioned archbishops and pronounced it archie-buiningiana, but as the name means the old form I presume it should be pronounced arki-buiningiana, as in the name archaeologist also meaning old?

Thanks Dave. That meanining would have been clearer if spelled as archaebuiningiana....

[DaveW]

My interest Ralph was because years ago I was given a "Rebutia buiningiana" which when I searched the Web did not match the pictures for that name. I later found out it was the old "R. buiningiana" nomen nudum, evidently still going round in cultivation with the original name of Ritter's which he later published as R archibuiningiana. No doubt there are probably still a few plants going round under this old name?

Must see if I can find the old Ashingtonia article, but got a wardrobe full of hundreds of cactus books and journals to wade through to find it.

Enjoyed the talk Ralph.

Thanks Phil it saves me looking. I had forgotten Ritter (= John Donald as editor on his behalf) had published some more Rebutia's in Ashingtonia. A few blank pages in the reproduction to skip through though.

The Ashingtonia journal was only published for a few years. It went downhill in later volumes as detailed here.
