Found in wet areas of the Neotropics, this species can grow to 7 meters height. Horsetails show promise as ground covers for dikes, road cuts, abandoned strip mines and other bare areas.

Understanding how these groups of plants are related to one another is crucial to understanding two pivotal events in the evolution of land plants; the evolution of a vascular system and the evolution of seed-bearing plants.

You may do so in any reasonable manner, but not in any way that suggests the licensor endorses myriocaetum or your use. UC Berkeley Botanical Gardens. Much of the world’s coal deposits are derived from these plants.

Horse tales: all about Equisetum myriochaetum | Tropical Biodiversity

Today, however, they have been reduced to mostly small, lanky plants. As new techniques and data become available scientists have changed their mind about how the early vascular plants, which include the ferns, horsetails and lycopsids are related to each other.

So-called because of their bristly appearance, the horsetails are an intriguing group of early plants that have existed since the Devonian period [1].

Despite their diminutive appearance, many horsetails are quite hardy and thrive in human disturbance. Today the fauna are usually smaller and horsetails are smaller. Love them or hate them, they have stood the test of time. Historically, the ferns and horsetails were believed to be separate lineages. Though they are not ferns, horsetails are frequently referred to as “fern allies. From Wikimedia Commons, the free media repository.


There is something to be said for these little plants.

The tallest of the extant horestails are the giant horsetail Equisetum giganteum and the Mexican giant horsetail Equisetum myriochaetum of Central and South America. Like all horsetails, Equisetum myriochaetum grows well in wet fertile areas and they are often found growing in tropical forests alongside streams and swamps.

These two species are known to reach heights of 16 ft. Our coal deposits were formed from the vegetation that grew during the carboniferous period. Dick Culbert from Gibsons, B. If the file has been modified from its original state, some details such as the timestamp may not fully reflect those of the original file. The following other wikis use this file: Best in a container or myriochaeutm an area protected by a deep root barrier to check spread of the rhizomes.

One Response to Horse tales: Under the microscope you can see that each spore has 4 legs or elaters that curl and uncurl fquisetum response to changes in the atmospheric water content. Back then, they comprised a considerable portion of those early forests.

All gardeners and allotment holders are familiar with horsetails and the problems of eradicating them from their land. Along with other early plants such as ferns, the horsetails formed the forests that the dinosaurs inhabited.

This image was originally posted to Flickr by Dick Culbert at https: The Equisetaceae comprise one remaining genus, Equisetum which is considered to have 2 sub-genera: Determining the number of species that exist in the Equisetaceae and how they mryiochaetum related to each other has been difficult because members exhibit a large amount of morphological plasticity and hybridisation occurs frequently.


Fossil evidence shows that they were a dominant part of the flora during the carboniferous period both in terms of species number and size [2].

Plant in full sun to light shade in a rich soil and keep moist. No acute toxicity of the phytoextract could be determined in Drosophila or in human lymphocytes myriofhaetum culture, ranging from 0.

More work needs to be done looking at the benefits rather than the mechanisms involved.

In this equisethm, phytotherapeutic extracts from Equisetum myriochaetum were investigated for genotoxicity in the in vivo wing spot test in Drosophila melanogaster and in the in vitro human micronucleus test. This page was last edited on equiaetum Decemberat The phylogenetic grouping of the land plants has been subject to a large amount of change over time and no grouping has gone unchallenged.

So what about keeping you warm in winter? Commonly known as scouring rush the horsetails have been used by early pioneers in America as well as desperate campers today to clean pans. However, the horsetails that grow today look very similar to the ones we see in the fossil record.

For this reason, horsetails such equidetum E. As well as being found in the Reading University tropical glasshouseEquisetum myriochaetum grows natively in myriochaetm and Central America between Mexico and Peru [7]. The high silicon content in their stems make them particularly good at scraping off dirt and polishing metal. Retrieved from ” https: Equisetum have superficial stomata and branched stems [5]. Hippochaetum is distinguishable from Equisetum by its sunken stomata and stems that are generally unbranched.
