Re: What is wrong with this Eulychnia?
This particular browning looks like it might be scale insects to me. I think it's perhaps not as widely known as it should be, but some armoured scale will cause brown patches that superficially resemble browning from other causes. Looking at the rightmost patch in the photo here, i think that is th...

Re: When is a stenocactus an echinfossulocactus?
You're certainly free to use any classification you want, but to say that there's no correct one isn't true - the plants did evolve in a particular way, it's just that we don't have enough information usually to resolve how that happened. We can point to Linnaeus's classification for instance, and s...

Re: New growth even though it's winter?
Thinning at the base sounds odd, might be an idea to see if it's alright, could be rot. The brown patches could be sunscorch, but probably not if you're growing them inside. Spider mite is a more likely possibility - are there tiny webbing strands on the plants?

Re: Winter disaster
Has the snow melted? If it stays there a while then the plants inside might not be too badly affected, since plenty of cacti have snow cover them in habitat, and you could retrieve them when it looks like warming up. Though it does depend on what you had growing in there - most other succulents won'...

Re: Rooting Obregonia denegrii
Hi! Ray, Thanks for the reply. I will bring it indoors to dry out and harden. In was told I wasn't watering my plants often enough and to water them every 3 weeks which I did now I have this problem. I have another Obregonia denegrii about the same size so I think I had better check that one out as...

Re: Carpobrotus edulis
They're naturalised here as well, and have hybridized with the native Disphyma, though no one seems quite sure if they're actually displacing it, since Disphyma seems to favor rockier areas of the coast.

Re: Caudex plants (for starters) and other caudex questions.
Pachycaul normally means plants with a thickened trunk(like baobabs) whereas caudiciform means an enlarged caudex at the base(sometimes undergound) that the stems grow out of. There's quite a few species that don't clearly fit into one or the other category though.

Re: How long can cacti live for?
...meaning some cacti, if their offsets survive, and their offsets' offsets survive, and so on, could genetically be 1000s of years old? I presume this will be the same for all plants that can propagate themselves vegetetively (sp) There's quite a few known clonal colonies of plants that date back ...

Re: Euphorbia identification
Just fyi, rib number isn't generally a good way of identifying species, because many will grow additional ribs over time.phyllonemus wrote:
