Hot springs

Stems with sporangia and are stem group tracheophytes

Simple shoots that grow from an axis and has simple branched stems. They lacked leaves, seeds and flowers with horizontal stems and roots.

No as they lacked true leaves

Consists of stems that is covered with small spines and has a vascular column

No

Xylem exarch

Consists of sporangium

Dichotomous or monopodial branching

Trimerophyta

Tropical habita
