Answer:
The structure involved in the reproduction of Rattlesnake fern is the spores.
Step-by-step explanation:
Botrychium virginianum is spread by spores. It is a difficult plant to grow. The division occurs during spring. Spores are difficult to germinate, require total darkness, and have a mycorrhizal relationship. You must have the fungus on the ground for the gametophyte to support. It is a slow growing plant. They produce only one pair of frond per year.
