If you see a vascular plant that is growing low to the ground with branching stems covered by small leaves and that produced leaves with a single vein, you are most likely observing a(n):

Equisetum (sphenophyta) plant

Explanation:

Equisetum plants are also termed "scouring rushes" because the epidermal cells have silica. This plant occurs in most tropics.

The Equisetum possess *branched stem* the form of whorls of leaves fused along most of the their own length to form ahead sheath joined at the node..Each *leaf contains a singular vascular bundle or *vein(single vein)* to the vascular tissue of the stem. The aerial and underground portion of the stems have epidermal cells with scattered stomata on them.

A cross section of the stem shows that inside the epidermal cells are thick-walled, which protect and support the plant. The cortex has a set of thin walled photosynthetic cells, which aid small leaves in photosynthesis.
