Evil Genius Posted February 7, 2012 (edited) Hi Barnard, welcome around here! Dont think it will stay like this. Bridgesii´s of that size tend to grow another rib. bye Eg Edited February 7, 2012 by Evil Genius Share this post Link to post Share on other sites
watertrade Posted February 7, 2012 Hi Bernard I was given some 4 ribbed bridgesii after searching for ages. then within weeks after I got my hands on them they grew another rib. good luck with yours though. Share this post Link to post Share on other sites

CβL Posted February 8, 2012 (edited) Yeah, the number of ribs is not genetically fixed (but the bounds are approximately fixed, through dependence on other variables), but is a function of current number of ribs, light levels, nutrient flux and water flux. In other words, a plant can usually drop or gain quite a few ribs, and they're not "locked" into a certain number. Another interesting meta-stable cacti phenomenon is the phase of the areoles. On a standard 6-rib Pachanoi, usually there are two phase groups, with three in each. In the more interesting ones, there are 3 phase groups, with two in each. On 7-ribbers it becomes a bit more complex and a lot less clear-cut, but you can still see phase patterns. And on 8-ribbers, usually 2 phase groups of 4 and 4. As an engineer and musician, I find this very interesting. ^^ Edited February 8, 2012 by βluntmuffin Share this post Link to post Share on other sites
