Wolffia globosa (Roxb.) Hartog & Plas

• Genus: Wolffia
• Botanical Background: First described by early botanists, Wolffia globosa has been revisited in taxonomic studies as researchers seek to better understand the evolutionary adaptations that lead to its minimalistic form.

• Geographical Range: This species is native to tropical regions of Asia, where it is often found in still or slow-moving freshwater bodies such as ponds, ditches, and paddy fields.
• Environment: Wolffia globosa flourishes in nutrient-rich water with moderate temperatures. It prefers conditions with high humidity and low water turbulence, making it well suited for calm aquatic environments.

Leaves

• Highly reduced, oval-shaped body functioning as both leaf and stem

• Simple, green structure lacking traditional leaf blades

• Adapted for floating and photosynthesis on the water’s surface

Inflorescence (Spadix & Spathe)

• Produces extremely small, inconspicuous flowers

• Lacks ornamental spathe or showy structures

• Pollination occurs via wind or water movement

Growth Habit

• Entirely aquatic and free-floating

• Reproduces primarily through vegetative budding

• Does not form tubers or rhizomes

Light Requirements

• Grows best in bright, indirect light

• Can tolerate ample sun, but harsh direct light may cause overheating

Watering & Humidity

• Requires a consistently moist, aquatic environment

• Perform regular water changes to maintain water quality and nutrient balance

Soil & Potting Mix

• Grown directly in water—no traditional soil needed

• Shallow aquatic setups or pond water with minimal substrate work best in cultivation

Temperature & Fertilizer

• Prefers temperatures between 20–30°C (68–86°F)

• Occasional application of diluted liquid fertilizer supports growth—avoid nutrient buildup

Division

• Propagates efficiently through rapid vegetative budding

• Clumps can be divided in cultivation to produce new individuals

Stem Cuttings (if applicable)

• Not applicable due to lack of stems or nodes for cutting-based propagation

Seeds

• Sexual reproduction is rare in cultivation

• Seed propagation is uncommon and less practical than vegetative methods

Typical Issues

• Algal overgrowth in nutrient-rich or stagnant water

• Occasional fungal infections under poor water conditions

Treatment Recommendations

• Maintain clean water through regular changes and filtration

• Use mild, aquatic-safe fungicides for fungal issues

• Adjust nutrient levels to reduce algae buildup

• Despite its tiny size, it provides habitat and food for microfauna

• Studied for use in wastewater treatment and as a sustainable protein source

• Valued more for ecological and scientific relevance than ornamental use

• Popular among researchers and aquaculture enthusiasts for its unique biology

Wild Population Status

• Wolffia globosa is not currently considered endangered

• Local populations may be impacted by water pollution and habitat modification

Market Availability

• Commonly found in aquatic plant collections and research institutions

• Primarily used for scientific, ecological, and sustainability research—not for ornamental purposes
