As Daiv says current thinking is that only the text volume will be reprinted, but the new text volume would contain pictures of species described since the original work was published. However until anything is printed nobody really knows what form it will take, or if the old pictures volume would b...

In botany the first name validly published, be it for a genus or species, always takes priority. However with some early names it was not always clear what plants of a present genus the original author was referring to, so if this becomes clear later the generic name may be altered to a later one th...

Have to wait until the spring in the UK then to see if it grows, unless it collapses to a heap of jelly in the winter before then and answers your question Steve.

Gives them character Ian, thats why you grew them in the first place, who wants boring symmetrical plants!

Good luck with the Pyrrhocactus umadeave Ian, I have been sent a lot of seed of it in the past and only managed to germinate a couple of seeds once that did not survive their first winter.

What no Digitostigma or Yavia, are you already growing these?

Hi Kelly you may be able to find a proper cactus dealer in your area, or maybe a cactus club. Here are the Cactus & Succulent Society of America's affiliated clubs:- http://affiliates.cssainc.org/" onclick="window.open(this.href);return false; Our British Cactus Mall links to cactus de...

Yes a Stenocactus, formally known as Echinofossulocactus at one time since it was thought that name took priority. Luckily it seems that proved unfounded and we are now back with Stenocactus again thank goodness. However you will find the plants listed under either generic name in books or articles.

Hi Tony and Jens. No never been on this Forum before Jens, but I sometimes linked to some Cactiguide articles on the British Cactus & Succulent Society Forum. Yes both greenhouses are unheated, though some of the more tender plants are brought in to the house to overwinter. The greenhouse is now...

The only things I use in addition to Hob's set-up are a remote cable release to avoid shaking the camera (even on a tripod) when making the exposure and I also tend to use a diffuser between the light source and subject to cut contrast, particularly on the bright sunny days our plants need to flower...

If you use the term "macro" you will need to define what you mean? Strictly speaking the term macro, which is often misused in photography even by professionals and photo journal editors, means an image of 1:1 (x1 or life sized on the sensor) or larger. Anything less than this is strictly ...

It's the humidity that makes both heat and cold feel greater than it is Maja, both for humans and plants. In no place in the UK it is said you are you more than 72 miles from the sea. So this does influence our atmospheric humidity, both summer and winter. The American troops came to the UK in WW II...

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...

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.

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...

Gymnocalycium denudatum? or something from that group of Gymno's
