Why is isoetes called Quillwort?
Isoetes is commonly called ‘Quill wort’ due to the quill (a large feather)-like structure of the leaves. The plant body consists of a condensed, lobed corm or axis that bears a tuft of roots at the base and long feathery leaves on the top.

Where are Quillwort found?
Evergreen quillwort can be found most commonly in shallow, running water in creeks, sloughs, and along densely shaded river shores in deciduous and mixed swamp forests. Cool, slightly acidic to circumneutral water is typical of these habitats.
What is a Quillwort plant?
Quillwort, (family Isoetaceae), family of about 250 species of seedless vascular plants of the order Isoetales. The plants are aquatic or semi-aquatic, and most are native to swampy, cooler parts of North America and Eurasia. See also lycophyte and lower vascular plant.
Are isoetes trees?
Overview. Like all land plants, Isoetes undergoes an alternation of generations between a diploid sporophyte stage and a sexual haploid gametophyte stage. However, Isoetes are small heterosporous semi-aquatic plants, with different reproductive needs and challenges than large tree-like land plants.
Do Quillworts have stems?
Isoetes plants also have unusual stems. They are short and swollen and grow underground. The unique stem is known as a ‘corm’; it contains two or three lobes that give the corm an overall appearance of a small onion. The outer layers of the corm are shed as the plant grows.
Why Lycopodium is called clubmoss?
Why Lycopodium is called clubmoss? The club-shaped appearance of these fertile stems gives the clubmosses their common name. Lycopods reproduce asexually by spores. The plants have an underground sexual phase that produces gametes, and this alternates in the lifecycle with the spore-producing plant.

Do Quillworts have Microphylls?
Isoetes species are typically small plants with long, narrow leaves that grow from the base of the plant. It is the presence of a single veined leaf, known as a ‘microphyll’, that distinguishes the quillworts and other lycophytes from all other vascular plants.
