I've been labelling my white-flowered D. capensis this name ("Alba") since I started growing them, but looking at the CP database, it says that it is a cultivar called D. 'Albino', published in 1989. I'm assuming this is the correct name, since "alba" hasn't been published. What does everyone name their plants then eg. "Alba", D. 'Albino', "White flower" ?

I call mine var alba, but then I'm a bit of a luddite...

What does everyone name their plants then eg. "Alba", D. 'Albino', "White flower" ? Naming conventions. D. 'Albino' is a named cultivar. If you are sure to have the named cultivar and nothing but the named cultivar for sure, you give it the name of the named cultivar. And you are not sure if it is the named cultivar or you received the plant with another name, you cannot use the name of the named cultivar for it without knowing if the plant has its origin in the named cultivar. |

mostly, yes, but it depends on the cultivar

I'm not wholly convinced that the cultivar actually exists anyway... I have grown and grow plenty of white flowered D. capensis. Not one of them meets the description -
"...lack of red colouration in the leaves and tentacles under various lighting conditions, including strong sun".

That's what I thought when I read the description. In full sun, my mature plants have a pinkish tint to them. Its only under lower light or in young plants that they appear pigment free. Below is some more text from the CP database:
In my opinion, the plant doesns't lack anthocyanins.

I think, and i'm just partially remembering some info, that there is a white flowered D. capensis which is otherwise like the "Typical" variety which they call D. 'Albino' because of the white flowers. then you have D. capensis "Alba" which is a plant completely lacking any red pigmentation both in the traps and the flower, even in full sun. none of my D. capensis "Alba" have flowered just yet so i'm not sure about flower colour, but i'm expecting white. the plant however remains completely green in full sun.

All the plants I have seen, or grow, have a faint touch of pink in the glands. I've always called my "alba," but i agree with this. There is a slight touch of pink, however faint, in the glands of all my "alba". I read once that the Drosera 'Albino' was a naturally occurring mutation, and was not cultivated specifically by humans. Therefore, could it really be called a cultivar if it occurred in nature? |

This is the best I have. My other white flowering D. capensis show pink in the glands. What do you think Stephen?  ;D |

That plant has direct sun, it's next to "normal" and all red plants.
I had noticed before this post came up just how pink the glands were on the other white flowered plants, most of which are self set
This potful shows a distinct lack of pink.
Your thoughts now? ;D

Send it further south for a year or two and you might get some believers.

you might get some believers. I made no claim, I requested a comment. However I take it from your reaction that the photo shows what you would expect to see in the elusive cultivar. I can take a photo of the same glands showing pink, all I need is my wife's arm close to the pot, she did that while I was looking at them with a X10 magnifier.  I have also noted the glands 'pinking' with the reflection from terracotta coloured pots or saucers. |
