In my last post I mentioned that Sarracenia flowers turn up as the petals fall. As William Shatner might say… “is that weird? or What?”
According to the literature, there was speculation that the flowers tilted upward to allow the pollen to fall down onto a stigma to self pollinate the flower just in case it didn’t get cross pollinated. Don Schnell states that is very unlikely. However, after taking a look at a couple of Sarracenia flava flowers… I think it’s possible, but clearly, not always. It really depends on the individual flower.
Take a look at the photo below. I’ve added red dots to show where the stigmas located.
The flower on the left shows that one of the stigmas is positioned at the bottom of the umbrella when the umbrella faces forward. In this case, I think it might be possible for the pollen to fall on the stigma. The flower on the right shows a different configuration. In this case, the stigmas are to the left and right of vertical. The pollen would like fall down between them.
However… after thinking about this I came to the realization that all this speculation may be for not! At this point, its likely that pollen is not viable anyway!
