Horsetails, ferns, club-moss, and whisk fern are all types of plants that belong to the group known as primitive or lower vascular plants.

Horsetail plants belong to the division Equisetum. They are usually found growing in damp areas and along riverbanks. Horsetails are also known as scouring rushes due to their rough texture, which was historically used for scrubbing pots and pans. Horsetails have a distinctive jointed stem and produce spores for reproduction.

Ferns belong to the division Pteridophyta. They are a diverse group of plants that vary in size from tiny epiphytes to large tree ferns. Ferns are known for their distinctive fronds or leaves which are called fronds. The fronds grow from underground rhizomes (a horizontal stem that grows underground) and have spores on their undersides, which allow them to reproduce.

Club-moss plants belong to the division Lycopodiophyta. They are small, evergreen plants that are similar in appearance to moss. Club-moss plants produce spores for reproduction and can be found in damp, shaded areas. Some species of club-moss are used for medicinal purposes.

Whisk ferns belong to the division Psilophyta. They are a small group of primitive vascular plants that are found in tropical and subtropical regions. Whisk ferns lack true roots, stems, and leaves but have specialized structures that allow them to absorb nutrients and water. They also produce spores for reproduction.

In summary, horsetails, ferns, club-moss, and whisk fern are all types of primitive vascular plants that have different physical characteristics and adaptations to their environment. Learning about these plants helps us to understand the diversity of plant life on our planet.
