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

• Genus: Bau
• Botanical Background: Described and named by botanists S.Y. Wong and P.C. Boyce. It was noted for its unique features that differentiated it from other members of the Bau genus.

• Geographical Range: Native to the lowland and montane rainforests of Malaysia and Indonesia, particularly in regions with high humidity and consistent rainfall.
• Environment: Grows in tropical, high-humidity environments with well-drained, slightly acidic soils. Requires moderate to high levels of rainfall and thrives in areas with filtered light under the canopy of larger trees

Leaves

• Large, glossy, and elongated
• Striking veins
• Exhibit a rich green coloration with occasional mottling or variegation

Inflorescence (Spadix & Spathe)

• Spathe is typically green with a yellowish tint at its base
• Spadix is slender and often has a subtle fragrance that aids in pollination by insects
• Pollination mechanisms remain poorly understood but are thought to involve typical insect activity

Growth Habit

• Primarily terrestrial but may exhibit semi-epiphytic tendencies in some environments
• Has a rhizomatic growth habit, producing new shoots from an underground rhizome

Light Requirements

• Prefers bright, indirect light
• Direct sunlight may scorch the leaves

Watering & Humidity

• Requires consistently moist soil but should not be waterlogged
• High humidity (60%+) is ideal
• Regular misting can help maintain optimal conditions

Soil & Potting Mix

• A well-draining, acidic potting mix
• Mixture of peat, perlite, and orchid bark provides an excellent medium
• Containers should have good drainage
  

Temperature & Fertilizer

• Ideal temperature range is 22-28°C (72-82°F)
• Fertilizing every 4-6 weeks during the growing season with a balanced, water-soluble fertilizer ensures healthy growth

Division

• Rhizome division
• Each division should include at least one healthy growth node
  

Stem Cuttings (if applicable)

• Cuttings are less commonly successful

Seeds

• Less common
• Require warm, moist conditions and can take several weeks to germinate

Typical Issues

• Spider mites and mealybugs
• Root rot can occur in overly moist conditions

Treatment Recommendations

• For pest control, use insecticidal soap or neem oil
• Root rot can be prevented by ensuring proper drainage and reducing watering frequency during cooler months

• Does not have widespread cultural or folkloric significance but is of ecological interest as part of the rich biodiversity in Southeast Asia's rainforests
• Prized specimen for collectors of rare aroids due to its striking foliage and unique growth form

• Sought after for decorative purposes in tropical-themed gardens and as a houseplant in appropriate climates

Wild Population Status

• No immediate threat to the species' population, though deforestation in its native regions poses a long-term risk
• Conservation efforts are not as widely documented for this specific species
  

Market Availability

• Considered rare in cultivation
• Not listed as endangered but is not commonly found in mainstream markets
