Hydrilla ( waterthyme) is a genus of aquatic plant, usually treated as containing just one species, Hydrilla verticillata, though some botanists divide it into several species. It is native to the cool and warm waters of the Old World in Asia, Africa and Australia, with a sparse, scattered distribution; in Australia from Northern Territory ...
Aquatic plants are plants that have adapted to living in aquatic environments ( saltwater or freshwater ). They are also referred to as hydrophytes or macrophytes to distinguish them from algae and other microphytes. A macrophyte is a plant that grows in or near water and is either emergent, submergent, or floating.
Epiphyte. Tillandsia bourgaei growing on an oak tree in Mexico. An epiphyte is a plant or plant-like organism that grows on the surface of another plant and derives its moisture and nutrients from the air, rain, water (in marine environments) or from debris accumulating around it. The plants on which epiphytes grow are called phorophytes.
Plants are considered carnivorous if they have these five traits:[18] capture prey in traps. kill the captured prey. digest the captured prey. absorb nutrients from the killed and digested prey. use those nutrients to grow and develop. Other traits may include the attraction and retention of prey.
The ferns ( Polypodiopsida or Polypodiophyta) are a group of vascular plants (plants with xylem and phloem) that reproduce via spores and have neither seeds nor flowers. They differ from mosses by being vascular, i.e., having specialized tissues that conduct water and nutrients, and in having life cycles in which the branched sporophyte is the ...
The Rhamnaceae are a large family of flowering plants, mostly trees, shrubs, and some vines, commonly called the buckthorn family. [2] Rhamnaceae is included in the order Rosales. [3] The family contains about 55 genera and 950 species. [4] The Rhamnaceae have a worldwide distribution, but are more common in the subtropical and tropical regions.
Description. Sagittaria sagittifolia is a herbaceous perennial plant, growing in water from 10–50 centimetres (4– 19⁄ inches) deep. The leaves above water are arrowhead-shaped, the leaf blade 15–25 cm (6–10 in) long and 10–22 cm (4– 8⁄ in) broad, on a long petiole holding the leaf up to 45 cm ( 17⁄ in) above water level.
The Alismatales comprise herbaceous flowering plants of often aquatic and marshy habitats, and the only monocots known to have green embryos other than the Amaryllidaceae. They also include the only marine angiosperms growing completely submerged, the seagrasses. [2] The flowers are usually arranged in inflorescences, and the mature seeds lack ...
