Re: BCSS Website - have your say
It is indeed Pedalo Phil and no its not a minor upgrade, some website content plus forum and gallery content is about the only thing that is guaranteed to survive. The whole platform will probably be Wordpress based, easy to use, easy to update and very configurable. ...and rife with security issue...

Re: Seed Quality - Inbred Cacti?
At last we have got to the point of this thread! IanW has subjected the reader to a lot of grumbling about authority, but finally writes about the central issue here. Whilst we are (inevitably) inbreeding many of our c&s, inbreeding depression is not much in evidence. I'm not sure why you're in...

Re: Seed Quality - Inbred Cacti?
IanW, from your last two paragraphs, you appear to be doubting the existence of inbreeding depression, re-interpreting the results as evolution - a very different set of processes. The example with maize that I quoted, Jones (1924), is from a modern botany textbook (Briggs and Walters, Plant Variat...

Re: Seed Quality - Inbred Cacti?
Another important issue is the conservation implications of genetic 'drift' for taxa in cultivation (or in captivity for animals). As few as five generations or crossing cutuivated plants (or captive animals) from original wild origins has been shown to produce such genetic change as to render stoc...

Re: CactiGuide
Quite possibly, but either way it's pretty clear that the spelling excentric of eccentric is all but dead in modern usage.

Re: CactiGuide
Yes, but meaning something completely different to "eccentric", which would seem to be a rather important thing to check:Ali Baba wrote:Sorry Ian but you are quite incorrect, both spellings appear in Chambers and the OED

Regarding excentric see the link below. "Alternative form of eccentric." https://en.wiktionary.org/wiki/excentric A Wiki that can be edited by anyone and that cites it's source as a single 1913 dictionary, vs. every other modern dictionary in the world (including the more modern version o...

Re: Astrophytums caput med. Advice please
I agree with Tina, I've tried and failed growing this species from seed a number of times (though am now succeeding) and find that the biggest problem with them when young is simply that they don't have the water retention of other species - their long thin spindly arms dry out easily, and their tap...
