Wolffiella denticulata (Hegelm.) Hegelm.

• Genus: Wolffiella
• Botanical Background: Described by botanist Christoph Friedrich Hegelmaier in the 19th century, who specialized in aquatic plants. The name "denticulata" refers to tiny teeth along the plant margin, though these are microscopic

• Geographical Range: Native to parts of the United States, Mexico, Central America, and the Caribbean.
• Environment: Grows in stagnant or slow-moving freshwater bodies like ponds, ditches, and marshes; Prefers nutrient-rich, calm environments and tolerates a range of pH and temperature conditions

Leaves

• Flattened, elliptical fronds measuring 0.5 to 2.0 mm in length
• Light green 
• Lack a midrib

Inflorescence (Spadix & Spathe)

• Rarely produced and extremely reduced
• Consisting of a single pistil and one or two stamens without a spathe or typical spadix
• Pollination is poorly understood and infrequent

Growth Habit

• Free-floating aquatic plant without roots
• Reproduces primarily through budding and fragmentation

Light Requirements

• Bright, indirect light or partial sun
• Can tolerate low light but grows more slowly

Watering & Humidity

• It should be kept in shallow, standing water
• No additional humidity is necessary

Soil & Potting Mix

• No additional humidity is necessary
• Grows freely on water surfaces in containers or ponds

Temperature & Fertilizer

• Warm temperatures between 20°C and 30°C
• Occasional dosing with a diluted aquatic plant fertilizer promotes healthy growth

Division and Cuttings

• Propagates rapidly through vegetative budding
• Fronds divide and form new plants, making it easy to cultivate
  

Seeds

• Rare and not a common propagation method
• Seed viability is not well-documented
  

Typical Issues

• Algal overgrowth in nutrient-rich water

Treatment Recommendations

• Ensure good water quality to minimize problems
• Manual thinning of mats
• Maintaining a balanced aquatic ecosystem helps prevent algae and rot
• Avoid over-fertilization
  

• Among the smallest flowering plants on Earth
• Plays an ecological role by providing habitat for microfauna and helping filter water

• Often used in aquaria, water gardens, and ecological research
• Fast growth and minimal care requirements make it appealing for natural filtration systems

Wild Population Status

• Not currently considered threatened
• Wide range and adaptability contribute to stable wild populations

Market Availability

• Available from specialty aquatic plant nurseries
• Often sold as part of duckweed mixes
