Equisetum is commonly known as horsetail. It belongs to the Equisetaceae family which is commonly referred to as the horsetail family. Horsetail is the only living genus Read more…
The sporangia are borne on the underside of peltate sporangiophores. The sporangiophores are arranged quite close to each other in terminal strobili or cone-like structures. Do horsetails have sporangia? In ferns and horsetails the dominant life phase is also diploid, and called the sporophyte which produces abundant haploid spores in Read more…
Equisetum gametophytes are small, uncommon produce archegonia, that produce eggs, and antheridia, that release haploid, flagellated sperm that are chemically attracted to the archegonia and fertilize the eggs, forming a zygote that grows into a diploid sporophyte that soon overgrows the gametophyte. Which are characteristics of horsetails? Horsetail has several Read more…
Horsetail (Equisetum arvense) can be a problem in perennial crops, where it is not readily controlled. How do horsetails photosynthesize? With horsetails, photosynthesis occurs in the plant’s stem. The stem is hollow and articulated, and several species produce whorled side branches that make the plant look like a small Christmas Read more…
Field horsetail (Equisetum arvense) and scouringrush (E. hyemale) are common perennial weeds found in wet soils (Figure 7). While these are just a few of the cone-bearing plants, there are many others. So no matter what time of year, you can find plants that bear fascinating cones! What is an Read more…
Extant lycophytes (clubmosses and quillworts) and monilophytes (ferns and horsetails) develop both free-living gametophytes and free-living sporophytes. These gametophytes and sporophytes grow in close contact with the soil and develop rhizoids and sporophytes, respectively. What type of plants have rhizoids? Rhizoids develop on the gametophytes of some land plants (liverworts, Read more…
In early spring it has a brown stem with spore-containing cones on the top. Once the cones have released their spores this weed gives way to a different appearance by turning green. Horsetails have jointed stems with a ring of long, slender, tube-like pointed leaves with branchlets at each joint. Read more…
One thing you will notice about horsetail is that it does not appear to have leaves. Leaves are present but they are reduced to small scales. Where are the leaves on a horsetail? Horsetails have segmented stems with extremely reduced leaves typically appearing non-existent. When present, the leaves grow in Read more…
Horsetail gametophytes are reduced and thalloid. Bisexual gametophytes grow from homospores and produce both antheridia and archegonia. What is unique about 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 Read more…
every four to six weeks. For horses wearing shoes, the RSPCA recommends: “shod horses need to re-shod every four to six weeks irrespective of whether they have worn the shoes out or not. Hooves grow continuously and when shod, the hoof cannot wear down as it can with an unshod Read more…
