I will be giving a lecture at the upcoming ICPS conference on Sarracenia and part of my lecture is discussing the definition of a species and how much variation is allowed within a species before a plant needs to be split into a new species. Too often people get the idea that a species, subspecies, variety, and even form must look like a particular picture they have in their head or perhaps saw on the internet. For example: Nepenthes robcantleyi and this dare I say it, infamous photo
So to challenge this idea that a species, subspecies, variety, or form MUST look like the picture in your head I have created these handy posters which I hope will be available to buy in the near future. As I create more I will post previews of them here.
The rows are as follows for the S. purpurea complex poster from top to bottom: Row 1 S. purpurea ssp. venosa, Row 2: S. purpurea ssp. montana, Row 3: S. purpurea ssp. venosa, Row 4: S. purpurea ssp. burkii, Row 5: S. purpurea ssp. venosa
And yes I meant the names as I said them above. I am of the opinion that there are no varieties of S. purpurea only subspecies and that includes S. rosea.
