Lemna landoltii Halder & Venu

• Genus: Lemna
• Botanical Background: Described by botanists Halder and Venu. Their work contributed to the understanding of aquatic aroids and helped highlight the ecological importance of these diminutive plants.

• Geographical Range: Found in freshwater bodies of South Asia
• Environment: Thrives in nutrient-rich, still water with high humidity.  Prefers calm conditions that allow it to float freely on the water surface.

Leaves

• Extremely small, generally oval or obovate in shape
• Smooth texture and a vibrant green coloration

Inflorescence (Spadix & Spathe)

• Flowering is rare and the inflorescence is reduced in size
• Flowers are minute and not the primary feature of the species

Growth Habit

• Aquatic, free-floating plant that reproduces mainly through clonal budding
• Lacks an extensive root system and does not form tubers or traditional rhizomes

Light Requirements

• Bright, indirect light conditions that simulate natural sunlight

Watering & Humidity

• Requires clean, still water and a consistently humid environment
• Regular water changes can help maintain optimum conditions

Soil & Potting Mix

• Ccultivation requires a support medium, a shallow container with a nutrient-rich substrate is adequate

Temperature & Fertilizer

• Ideal water temperatures range from 20°C to 30°C
• Diluted aquatic fertilizer can be used

Division and Cuttings

• Propagation occurs almost exclusively via vegetative budding
• Clonal division of fronds is the simplest and most common method to increase populations

Seeds

• Seed production is infrequent, and germination is not typically used for propagation in this species

Typical Issues

• Can be affected by fungal infections and water pollutants

Treatment Recommendations

• Organic treatments or mild fungicidal application
• Ensuring optimal water conditions

• Used as a bioindicator in water quality studies and plays a role in natural water purification
• Simplicity makes it a favorite model organism for ecological research

• Adds a subtle, tropical charm to indoor gardens and specialized aroid collections
• Unique characteristics and rapid growth make it valuable in scientific studies and sustainable water management practices

Wild Population Status

• No major conservation concerns; localized water pollution and habitat changes can impact natural populations

Market Availability

• Commonly used in research settings and can be sourced from specialized aquatic plant suppliers rather than mainstream horticultural markets
