Bucephalandra sp. Mahakam Ulu

The Mahakam Ulu River Native

What Is Bucephalandra sp. ‘Mahakam Ulu’?

Bucephalandra sp. ‘Mahakam Ulu’ is a locality-based Bucephalandra collected from the Mahakam Ulu region in East Kalimantan, Borneo. The term “sp.” means the exact species has not been formally identified, so it is known by its collection location.

Like all Bucephalandra, it naturally grows attached to rocks and driftwood along fast-flowing jungle streams. It is a true aquatic plant that can grow fully submerged in aquariums or emersed in high-humidity environments.

Depending on the specific form, this variety may display green to darker tones, sometimes with a subtle metallic sheen. Its wild origin makes it especially attractive to collectors who value authentic Borneo river plants.

Natural and regionally distinct, Bucephalandra sp. ‘Mahakam Ulu’ brings a true rainforest stream character into aquascapes.

How It Grows

This plant grows from a creeping rhizome that attaches firmly to rocks or driftwood. It spreads slowly and forms compact clusters over time.

Growth is slow under stable aquarium conditions.

The Leaves

The leaves are firm and slightly structured.

• Color: medium to deep green, sometimes darker under lower light

• Surface: smooth with light natural sheen

• Shape: oval to slightly elongated

Leaf size and tone may vary depending on the specific collected form.

Light Needs

Prefers low to medium light.

• Moderate light supports healthy growth

• Avoid excessive lighting to reduce algae risk

Stable lighting helps maintain consistent foliage.

Water & Aquarium Conditions

• Attach to rock or driftwood

• Do not bury the rhizome

• Thrives in clean, well-circulated water

• CO₂ is optional but can improve growth

• Ideal temperature: 22–28°C

Stable water parameters are important.

Growing Environment

Best suited for:

• Freshwater aquariums

• Nano tanks

• Nature-style aquascapes

• Paludariums (emersed form)

Care Level

Low care.

• Suitable for beginners

• Slow-growing and easy to maintain

• Minimal trimming required

Handling Note

Always keep the rhizome above the substrate to prevent rot. Once attached and stable, Bucephalandra sp. ‘Mahakam Ulu’ will grow steadily and maintain its natural river form.
