Horsetail Morphology and Botanical Overview
Horsetail (genus Equisetum) is a distinctive, non-flowering vascular plant that has been admired for millennia. Often referred to as a “living fossil,” horsetail is one of the oldest plant genera on Earth, with fossils dating back over 100 million years. Unlike most modern plants, it reproduces via spores rather than seeds, and its structure is characterized by jointed, hollow stems and a high content of silica. These stems, which rise in graceful, segmented whorls, give the plant its striking, reed-like appearance.
Botanical Characteristics
Horsetail’s anatomy is remarkably unique. The plant lacks conventional leaves; instead, it has reduced, scale-like structures along its stems. These stems are typically green, though some species exhibit a yellowish or even brownish hue as they mature. At each node, tiny branchlets—called “ribs”—extend outward, providing additional support and increasing the surface area for photosynthesis. The plant produces small, inconspicuous spore-bearing cones (strobili) that cluster at the tips of the stems. These cones release spores into the air for reproduction, enabling horsetail to colonize a variety of habitats.
