Lemna valdiviana Phil.

• Genus: Lemna
• Botanical Background: Named by the botanist Rodolfo Amando Philippi, Lemna valdiviana has been studied for its efficient growth and adaptation to aquatic environments, contributing valuable insights into plant ecology.

• Geographical Range: Native to freshwater habitats in South America, particularly in regions with temperate climates such as Chile’s Valdivia area.
• Environment: Thrives in still or slow-moving freshwater bodies with moderate nutrient levels and stable temperatures, often found in ponds, lakes, and sheltered streams.

Leaves

• Tiny, oval to elliptical fronds
• Smooth texture and uniform green coloration
• Lacking complex venation patterns

Inflorescence (Spadix & Spathe)

• Produces minimal inflorescence that is generally inconspicuous
• Reproduction is largely vegetative, with flowering occurring rarely

Growth Habit

• Aquatic, free-floating plant that spreads rapidly by budding
• Reduced root system that anchors loosely in the water column

Light Requirements

• Flourishes in bright, indirect light, making it suitable for outdoor ponds or indoor aquatic setups

Watering & Humidity

• Requires a constant water environment with clean, nutrient-balanced conditions to prevent excessive algae growth

Soil & Potting Mix

• Typically grown in shallow water without traditional soil
• Can be maintained in containers or ponds that support free-floating growth

Temperature & Fertilizer

• Thrives in moderate temperatures ranging from 15 to 30 °C
• Minimal fertilization is needed
• Slight nutrient boost can enhance growth under controlled conditions

Division and Cuttings

• Most common method of propagation is vegetative, where new fronds bud off from the parent plant, quickly expanding the colony

Seeds

• Seed production is uncommon in natural settings, making vegetative reproduction the primary propagation strategy

Typical Issues

• Fungal infections and occasional algal overgrowth if water quality is compromised

Treatment Recommendations

• Improving water circulation, maintaining balanced nutrients, and removing affected fronds
• Organic treatments or mild chemical controls may be used when necessary

• Often used in water purification studies and as a model organism in ecological research due to its rapid growth and sensitivity to environmental changes
• Not typically prized for ornamental display

• Its role in aquaria, research, and bioremediation highlights its practical and ecological significance

Wild Population Status

• No significant conservation concerns

Market Availability

• Widely available through aquatic plant suppliers and research collections
• Accessible for both hobbyists and scientific study
