Lemna tenera Kurz

• Genus: Lemna
• Botanical Background: Described by Kurz, this species has been the subject of ecological and botanical studies, particularly in relation to its rapid propagation and utility in bioremediation research.

• Geographical Range: Primarily found in freshwater bodies across tropical and subtropical regions of Asia.
• Environment: Thrives in nutrient-rich, still or slow-moving waters, often in warm climates with high humidity.

Leaves

• Tiny, oval to heart-shaped fronds
• Smooth texture and a uniform green coloration

Inflorescence (Spadix & Spathe)

• Flowering is rare
• Relies on asexual reproduction, with minimal floral structures observed when they occur

Growth Habit

• Forms dense mats on water bodies
• Reproduces predominantly through budding from a basal rosette, rather than by producing tubers or climbing

Light Requirements

• Prefers bright, indirect light, which supports its photosynthetic efficiency without causing overheating

Watering & Humidity

• Requires a stable water environment that remains clean and well-aerated
• Regular water changes help maintain optimal growth conditions

Soil & Potting Mix

• Typically occurs in shallow ponds or controlled aquatic setups rather than in traditional soil-based containers

Temperature & Fertilizer

• Thrives in warm temperatures
• Periodic supplementation with diluted aquatic fertilizers can boost its growth while preventing nutrient deficiencies

Division and Cuttings

• Propagates mainly through vegetative budding, where new fronds separate naturally from the parent plant to form dense colonies

Seeds

• Seed formation is infrequent and not the primary method of propagation

Typical Issues

• Susceptible to fungal infections and algal overgrowth

Treatment Recommendations

• Ensuring clean water conditions and balanced nutrient levels
• Improving water quality
• If necessary, applying mild organic antifungals

• Rapid clonal growth and efficient nutrient uptake make it an important species for ecological studies and potential applications in wastewater treatment and bioenergy production.
• Unique, minimalistic structure and ease of propagation appeal to aquatic enthusiasts and researchers interested in sustainable water management.

Wild Population Status

• Does not face significant conservation threats; however, local populations may be impacted by water pollution and habitat disruption.

Market Availability

• Readily available for scientific research and environmental applications 
• Though it is less common in the conventional horticultural market
