Lemna bistrosa Charit.

• Genus: Lemna
• Botanical Background: Described by botanist Charit, In the early 20th century, Lemna bistrosa has been an object of study mainly in aquatic ecology and water quality research, contributing to our understanding of clonal propagation in simple plants.

• Geographical Range: Native to temperate regions of Europe and parts of Asia, where freshwater ponds, lakes, and slow-moving streams provide ideal habitats.
• Environment: Thrives in environments with calm, nutrient-rich water; commonly found in eutrophic conditions where high humidity and stable water temperatures.

Leaves

• Small, oval, green fronds with a smooth texture
• Adapted to float on the water surface, often displaying a slight translucence

Inflorescence (Spadix & Spathe)

• Flowering structures are rarely observed, with reproduction occurring mainly through vegetative means

Growth Habit

• Aquatic, free-floating plant that reproduces primarily by budding
• Does not develop extensive rhizomes or tubers, relying instead on clonal propagation

Light Requirements

• Grows best in bright, indirect light
• Direct sunlight should be moderated to prevent overheating of the water environment

Watering & Humidity

• Fully aquatic, the plant requires a consistent water environment
• Maintaining moderate humidity and stable water quality

Soil & Potting Mix

• Typically cultivated in water rather than soil
• Benefits from a nutrient-rich aquatic medium
• Containers designed for water plants
  

Temperature & Fertilizer

• Prefers temperatures between 18 and 28°C
• Occasional feeding with a diluted aquatic fertilizer can promote robust growth

Division

• Propagation is achieved mainly through the natural process of budding and division

Seeds

• Seed production is infrequent, and when it occurs, seeds require calm water conditions to germinate effectively

Typical Issues

• Algal overgrowth and occasional infestations by waterborne pests
• Root rot can occur if overwatered or kept in poorly draining soil

Treatment Recommendations

• Organic treatments and improved water circulation are advisable
• Ensuring a balanced aquatic ecosystem

• Valued for its rapid growth rate, which makes it a useful bioindicator of water nutrient levels
• Ability to absorb excess nutrients contributes to natural water purification processes

• Unique appearance and ease of propagation make it popular in aquascaping and ecological studies
• Minimalistic design offers a distinctive appeal for enthusiasts

Wild Population Status

• Not considered threatened

Market Availability

• Widely available through scientific research collections and specialized aquatic plant suppliers
• Not typically cultivated for ornamental trade but is accessible for ecological and experimental purposes
