The correct term for the 'dots' on the underside of the fern is sori, singular sorus. In each sorus are many sporangia. In each sporangia are 64 spores, mostly. There can be a million spores from one fern plant.

A trait of ferns is no flowers, thus no pollen.

Ferns evolved before flowering plants.

Fern stems reveal secrets of evolution – how constraints in development can lead to new forms Is an organism a sum of its parts, or should they be considered as a whole? New research on ferns shows how the way scientists understand evolution affects how they study life.

Why aren’t there square trees or mammals with wheels?

A new study of fern stems shows how linked traits β€” developmental constraints β€” shape the limits and possibilities of evolution.

It is an interesting study. The article does not state the relative weight ratio and extrapolate to the number of hectares to extract a kilo of REEs, as well as compare to the amount of REEs found per ton of ore.

The description of Sensitive fern, Onocela sensibilis is correct.

It is a once-cut fern with a triangular frond. Sporangia appear on separate fertile stalks.

The picture shows what looks like Royal Fern, Osmunda spectabilis.

Royal fern is twice-cut, sporangia appearing at the tips of the frond.
