What is unique about Equisetum?

The stems are usually green and photosynthetic, and are distinctive in being hollow, jointed and ridged (with sometimes 3 but usually 6–40 ridges). There may or may not be whorls of branches at the nodes.

What are the adaptations of a horsetail plant?

As the fertile stems wither, the sterile, chlorophyll-producing secondary stems appear, covered with whorls of feathery green branches. The energy they gather through photosynthesis goes to underground tubers for storage, allowing horsetail to survive harsh winters and periods of drought.

Which are characteristics of horsetails?

Horsetail has several distinguishing characteristics. One such characteristic is horsetail’s hollow stems (Figures 1 and 3). Its stems also are jointed, can easily be separated into sections, and have siliceous ridges that make it rough to the touch.

Why is Equisetum called scouring rush?

Because the stems are rough and durable (due to their high silica content) they were called “scouring rushes” because early pioneers used them to scrub pots and pans. Both scouring rush and horsetail prefer moist soil, but either will tolerate fairly dry soil after they become established.

How does Equisetum help the environment?

The stems of equisetum contain high concentrations of silica and were once used to scour and clean various surfaces – hence the name scouring rush. Horsetail and scouring rush are most commonly found in poorly drained areas, such as roadsides, wetlands and drainage ditches.

What is economic importance of Equisetum?

Uses: Equisetum is of economic importance to the stock farmer as it is poisonous when consumed in large quantities, the toxic principle probably being the enzyme thiaminase that destroys vitamin B1. This causes livestock to appear drunk and they may harm themselves.

What type of spores does Equisetum produce?

Equisetum plants (horsetails) reproduce by producing tiny spherical spores that are typically 50 µm in diameter. The spores have four elaters, which are flexible ribbon-like appendages that are initially wrapped around the main spore body and that deploy upon drying or fold back in humid air.

What characteristics would you use to distinguish a fern from a horsetail?

what characteristics would you use to distinguish a fern from a horsetail? horsetails are found in moist areas. ferns can be woodland plants; aquatic, or in desert forms. ferns have more vascularzation than other seedless vascular plants.

What makes Equisetum rough?

The stems themselves have conspicuous ridges, which are impregnated with silica. This makes the ridges feel rough and harsh. The tiny leaves are joined together around the stem, forming a narrow black-green band or sheath at each joint.

What is horsetail plant used for?

Horsetail is a plant. The above ground parts are used to make medicine. Horsetail is used for “fluid retention” (edema), kidney and bladder stones, urinary tract infections, the inability to control urination (incontinence), and general disturbances of the kidney and bladder.
