Abstract
I RECENTLY had an opportunity of examining living specimens of a very rare British plant, the intermediate bladderwort (Utriculana intermedia), and found that the leaf-bearing stems ended in a solitary terminal knob or nodule, the largest being the size of a small peppercorn. What are these knobs? Are they autumn plant-buds that will ultimately grow into plants? This seems to me a possible solution; but (my edition of) Bentham does not mention that the plant propagates itself in this way, nor are the knobs figured in the companion volume of illustrations by Fitch and Smith.
