This Mexican Pinguicula species gets its Latin name from the fact that it shows two different leaf types, at separate stages of its growth cycle, once it emerges from its underground dormancy.
The first leaves to emerge after dormancy are shorter, wider and triangular in shape, and lay pressed flat to the ground.
Just before the second type of leaves get started, there occurs an intermediate leaf or two that is decumbent in nature, still triangular in shape, slightly more elongated than the first leaves, but with upturned leaf tips.
Then the long and narrow filiform leaves take over, unfurling from tightly rolled up, cork-screwed leaf tips.
Propagation of this species can be done with leaf pulls, as well as from seed and occasionally the underground bulbs will divide, sending up two separate growth points, side by side.
Here is a swollen seed capsule, which resulted from a recent manual pollination.
And, though it is hard to capture with camera, the plant on the left, has sent up two growth points from its underground bulb, during this growing season.
