Early botanists admired ferns but found their life cycle perplexing. In the 1700s, they learned to propagate ferns by sowing what appeared to be tiny dust like “seeds” that they collected from the undersides of fronds. Despite many attempts, the botanists could not locate the pollen source, which they assumed must stimulate these “seeds” to develop. Imagine you could write to these botanists. Compose a note that explains the fern life cycle and clears up their confusion.
