Bau tessellata (S.Y.Wong) S.Y.Wong & P.C.Boyce

• Genus: Bau
• Botanical Background: Described by botanists S.Y. Wong and P.C. Boyce, Bau tessellata was noted for its distinctive leaf patterns, which were of particular interest to researchers studying aroids.

• Geographical Range: Native to the tropical rainforests of Southeast Asia, with confirmed occurrences in countries such as Malaysia and Indonesia.
• Environment: Thrives in humid, shaded areas, often in lowland rainforests or on forest floors. Prefers well-draining soils and moderate temperatures, typically ranging between 25–30°C (77–86°F)

Leaves

• Large, with an intricate, tessellated (net-like) pattern
• Ranges in green hues
• Leathery texture and a glossy finish

Inflorescence (Spadix & Spathe)

• Consists of a typical aroid spadix surrounded by a cream or pale green spathe
• The spathe is relatively small, and the spadix can produce a mild odor
• Pollination is often carried out by beetles or flies

Growth Habit

• Typically terrestrial, growing on the forest floor
• Has a rhizomatous root system, allowing it to spread horizontally

Light Requirements

• Thrives in bright, indirect light
• Direct sunlight can scorch its delicate leaves, so it is best grown in a location with filtered light

Watering & Humidity

• Requires consistently moist soil
• High humidity levels
• The plant benefits from misting or placement in a humidity tray to maintain a favorable environment

Soil & Potting Mix

• A well-draining, rich potting mix with good organic matter is ideal
• Mix containing peat, perlite, and orchid bark is often recommended for this species

Temperature & Fertilizer

• Optimal temperature for this plant ranges from 25–30°C (77–86°F)
• Balanced liquid fertilizer applied monthly will support healthy growth during growing season

Division

• Rhizome division

Stem Cuttings (if applicable)

• Cuttings can also be taken from healthy nodes, though care must be taken to ensure they are placed in humid, warm conditions to root properly

Seeds

• Not commonly practiced
• Require moist, warm conditions to germinate, but their viability can be low in cultivation

Typical Issues

• Mealybugs, spider mites, and aphids
• Root rot is a frequent issue

Treatment Recommendations

• Regularly inspect the plant for pests, particularly under the leaves
• Neem oil and insecticidal soap are effective organic treatments
• For root rot, ensure proper drainage and avoid overwatering
  
• Fungicides can be applied for severe fungal infections
  

• The unique leaf pattern of Bau tessellata is highly prized by collectors. In some cultures
• In some cultures, aroids like this are seen as ornamental plants for decorative purposes in gardens

• Valued for its striking foliage, making it an attractive addition to ornamental collections
• A rare find among aroid enthusiasts, sought after for its eye-catching leaves

Wild Population Status

• No major conservation concern
• Habitat loss in its native range could pose future risks if deforestation continues at the current rate

Market Availability

• Relatively rare in the ornamental plant market
• Often only available through specialized aroid growers or collectors
