Re: Need help about storing cacti!

Different genera vary since it depends where they normally grow. Even genera growing in the same habitat area with a mile or so of each other can prefer different conditions because it often depends on the altitude they inhabit. In S. America you can get genera that live in the deep hot valleys that...

Re: New plant

As Ian has already explained regarding the genera concerned they have now been sunk into Eriosyce. Your plant looks like Eriosyce tuberisulcata (syn. horridus). The flower colour varies from yellow to red in different plants. Here is a habitat picture from my friend Roger Ferryman.

Re: Two cacti to id

I agree with Ian and tacrolimus , I also picked up one of those yellow spined Denmoza's in Spain last year which fooled me for a while since the common form is red spined. There seems a few spine colour forms "flavispina" being a nomen nudum as it is unpublished. If you click on the differ...

Re: cacti for ID

Hard to tell what it is from the photo, but it looks as if it certainly has gone "blind" (growing point in crown has died) and so is producing offsets from the side and near the crown. Best wait until you get an offset large enough then cut it off and re-root it to get a normal plant again.

Re: New edtions ID please

I agree with vlani, the second is what used to be called a Pseudolobivia before being lumped into Echinopsis and is one of the red flowered forms of the obrepanda types. It is simply a case of how many names you lump into synonymy whether you consider flower colour alone defines a species.

Re: A Rebutia of some sort??

It's a Sulcorebutia, but I would need to look up the species as there are so many.

Re: 50+ years.

I remember Hob from some time back too Rod. Thanks hoteidoc, nice to meet anybody with an interest in cacti. I am afraid though I am a dyed in the wool cactophile since I do not grow any Other Succulents. You in the US and warmer countries have a longer growing season than we do, which is why our pl...

Re: Echinocereus rigidissimus

My rubispinus has had a bit of a sulk since flowering, but seems to have picked up a bit this year, so hopefully it has now re-rooted since being re-potted. E. rigidissimus rubispinus was discovered by Alfred Lau and is an unusual Echinocereus in that it's stigma lobes are not green, which is one of...

Re: newbie question, why there is no trichocereus

"It is quite confusing as most people still use Trichocereus even though the correct name now is Echinopsis." Classification is simply a matter of opinion. As long as a name is validly published according to the "rules" you are allowed to use it. There never has been only one cla...

Re: Camera advice?

Unless it has a continuous autofocus mode the autofocus stops as soon as you partially depress the shutter button on most digital cameras to hold that focus. Not a problem in normal photography, but in macro photography with often depths of field of a few millimeters you can sway out of focus before...
