Lemna disperma Hegelm.

• Genus: Lemna
• Botanical Background: Described by Hegelm. and has since been a subject of interest for botanists studying aquatic plant adaptations and reproductive strategies

• Geographical Range: Native populations are found in freshwater environments across temperate and tropical regions, including parts of Europe, Asia, and Africa.
• Environment: Thrives in still or slow-moving water bodies with abundant sunlight and moderate temperatures.

Leaves

• Small and oval to round in shape with a light green hue
• Simple structure and a smooth texture

Inflorescence (Spadix & Spathe)

• Flowering is rare
• Inflorescence is reduced with inconspicuous flowers that lack a pronounced spathe

Growth Habit

• Aquatic, free-floating plant that reproduces primarily through vegetative budding
• Forms dense mats on the water surface without the development of significant underground structures

Light Requirements

• Best in bright, indirect light
• Can tolerate moderate levels of direct sunlight as long as the water does not overheat

Watering & Humidity

• Requires a continuous supply of clean water
• Maintaining a balanced nutrient level in the water

Soil & Potting Mix

• Grown in shallow water rather than soil
• Minimal, nutrient-poor medium is recommended

Temperature & Fertilizer

• Optimal temperature range is moderate to warm
• Occasional supplementation with a balanced, water-soluble fertilizer

Division and Cuttings

• Propagation occurs mainly through vegetative division, with new fronds budding off the parent plant

Seeds

• Seed production is uncommon due to its predominant vegetative mode of reproduction

Typical Issues

• Algal overgrowth and waterborne fungal or bacterial infections, especially if water quality declines

Treatment Recommendations

• Maintain clean water, avoid stagnant conditions
• Consider natural treatments that control algae and fungi without harming the plant

• Used in ecological research and studies on water purification.
• Not typically used for ornamental purposes, this species is valued in scientific research and sustainable water management.

Wild Population Status

• Generally abundant, local populations may be sensitive to water pollution and habitat changes

Market Availability

• Widely available for research and in aquatic plant collections
