doubts on ID
Posted 10 June 2012 - 14:45 PM
1) obtained as S. purpurea subsp. venosa, but could it be a S. rosea, due to the pinkish colouration of the petals?
2) obtained as S. x rehderi = S. rubra x minor), but it has little white spots, in low number, on only some of the pitchers (possibly you can see them on the 2 smaller pitchers below)... can it still be a rehderi? is it a more complex hybrid (introgressed?)? is it a pure S. rubra (and which subspecies?)?

I wouldn't say that it has few minor traits, compare it to a pure rubra and you will see that it has quite a bit of minor influence. Colouration, veining, overhanging hood, slight fenestration etc.

I would go with burkeii myself.

And this is the flower of my S. purpurea subsp. purpurea... the difference in colour is remarkable:

- Sarracenia rubra subsp. gulfensis
- Sarracenia rubra subsp. gulfensis f. luteoviridis
Are they right?

Many growers simply deleted the last part of the name under the impression it was superflous. The name is Sarracenia purpurea venosa burkii. Since books keep being published that state these two are the same taxon, many people are under the impression all "burkii" refers to is a pink flowered variation of venosa, not an entirely different taxon. They have been bred together for years and years now. Its really quite sad that these hybrids are being distributed as good examples of S. purpurea venosa. The photos do appear to depict a plant with intermediate characteristics, but looks generally more like S. rosea...
The flower odors are different for each species and the hybrid too... So might help you ID it better...

I'll let also my presumed S. p. venosa var. venosa flower, to do a comparison.
