Natural Variation in the Parodia rutilans
Here are pictures of 5 different individuals, all the same species, in full bloom. So much variation! They are all Parodia rutilans. Here I blogged another Parodia that had significant variation as well.
And finally what we have here is what we have identified as Notocactus roseiflorus, which my copy of Anderson insists is also Parodia rutilans.
That sure is a lot of natural variation for today! And to be clear, those really were all in bloom and fully open yesterday all at the same time. Nice!
