Scientific definition of Oblong Wolffia
Scientifically known as Wolffia Oblong, the Oblong Wolffia belongs to the Araceae family (also known as the Arum family), which majorly includes duckweeds, and is part of the Wolffia genus that consists of eleven known species. It is a flowering aquatic plant, considered one of the smallest and simplest flowering plants in the world.
Common names and synonyms for Oblong Wolffia
Classified as “Wolffia oblonga” scientifically, Oblong Wolffia is also commonly referred to as “watermeal” due to its appearance resembling fine meal or grain. The term “Wolffia” is named after the German botanist, Johann Friedrich Wolff, who extensively studied these tiny plants.
Brief natural history of Oblong Wolffia
The natural history of Oblong Wolffia is indeed as interesting as the plant itself. Being part of the first plants to evolve the ability to flower, it thrived in aquatic environments, adapting creatively to survive and reproduce.
Physical Characteristics of Oblong Wolffia
Size and appearance of Oblong Wolffia
One of the incredibly noticeable characteristics of Oblong Wolffia is its size. An adult plant is barely larger than a grain of rice and generally measures less than a millimeter long. Its appearance is akin to a green seed, oval-shaped, and floating on water bodies.
Unique microscopic features of Oblong Wolffia
Under the microscope, unique characteristics of the Oblong Wolffia come to light. It lacks stems, roots, or true leaves. This highly simplified morphology is a result of millions of years of evolutionary adaptation to their aquatic lifestyle.
Fruit and seed structure and identification
As with other duckweeds, oblanceolate to oblong Wolffia reproduces primarily through a type of asexual reproduction where a new plant grows out of the parent plant. However, it also bears minute flowers that rarely fruit and form seeds. Due to their tiny size, the identification process is considerably challenging and often requires microscopic analysis.
Habitat of Oblong Wolffia
Common water bodies where Oblong Wolffia are found
Oblong Wolffia finds its home in stagnant or slow-moving water bodies. They are often found in abundance in ponds, lakes, marshes, and slow-moving streams where they form dense, green blankets on the water surface.
Climatic conditions favorable for Oblong Wolffia
Warm, temperate climatic conditions are optimal for the growth of Oblong Wolffia. They also show a high level of tolerance to different pH levels and nutrient variations.
Geographical distribution of Oblong Wolffia
Geographically, Oblong Wolffia has a wide distribution range, occurring in parts of Asia, Australia, North America, and Central America.
Growth and Reproduction of Oblong Wolffia
Life cycle of Oblong Wolffia
The typical life cycle of the Oblong Wolffia usually begins from a budding flower. With sunlight and nutrients, it grows into a mature plant within a short period, and soon, new buds start to form, thus completing the cycle.
Factors affecting the growth of Oblong Wolffia
Water temperature, light intensity, nutrient availability, and pH levels are a few crucial factors affecting the growth of Oblong Wolffia. Change in these factors may lead to changes in the growth rate or abundance.
How Oblong Wolffia reproduces
Reproduction in Oblong Wolffia is predominantly through vegetative means, where new plants grow from the ‘mother’ plant. The minute flowers are rarely formed and even rarely fertilized due to their enclosed position within the plant.
Ecological Role of Oblong Wolffia
