Description of Oncocalamus macrospathus Burret
Oncocalamus macrospathus Burret is a plant that belongs to the Arecaceae family.
Origin of Oncocalamus macrospathus Burret
This species is native to the tropical rainforests of Borneo, an island in southeast Asia.
Common Names of Oncocalamus Macrospathus Burret
This plant is also known as Borneo Giant Rattan, and locally it is called "Rotan Jelutong."
General Appearance
Oncocalamus macrospathus Burret can grow up to 50 meters tall, and its stem can reach a diameter of up to 20 cm. The stem of this plant is characterized by a brown color with a rough texture.
Its leaves are pinnate, which means that they are feather-like, and can grow up to 4 meters long. These leaves are dark green and have spiny edges that can cause injuries.
Unlike many other palm species, the flowers of Oncocalamus Macrospathus Burret grow beneath the leaves rather than on a spike. This plant produces a small fruit that is edible, often consumed by monkeys and other forest animals.
Uses
The strong and flexible stems of Oncocalamus macrospathus Burret have been used for many traditional purposes, including the fabrication of baskets, roof thatching, and furniture.
Additionally, extracts from the plant are used in traditional medicine to treat various symptoms such as rheumatism and fever.
In recent years, this plant has also gained popularity among horticulturists as an ornamental plant.

Soil Requirements
Oncocalamus macrospathus Burret is typically found in well-draining soils such as sandy or loamy soil. The plant grows best in soils that have a pH range between 6.0 to 6.5, which is slightly acidic. Additionally, the plant requires a soil that is rich in nutrients, especially nitrogen and phosphorus.
Cultivation methods
Oncocalamus macrospathus Burret, also known as the climbing bamboo or the African climbing bamboo, is a tropical plant that is native to Africa. It is a fast-growing and climbing bamboo species that can reach heights of up to 30 meters. The plant prefers well-drained soil, and it's suitable for growing in tropical and subtropical climates. To cultivate Oncocalamus macrospathus Burret, consider the following:
- Choose a location with well-drained soil and partial shade.
- Plant the bamboo in a hole that is at least twice the size of the root ball, and water it generously after planting.
- Install a sturdy trellis or support system for the plant to climb on.
- Keep the bamboo moist, but not waterlogged, during the growing season.
- Prune the bamboo regularly to promote new growth and maintain its shape.
- Fertilize the plant with a balanced fertilizer every six months.
Watering needs
Oncocalamus macrospathus Burret requires moderate watering, especially during the growing season. The plant does well in moist soil, but it doesn't tolerate standing water. Irrigate the bamboo frequently enough to keep the soil evenly moist, but not waterlogged. Water the plant deeply once a week during the dry season and reduce watering during the rainy season. Be sure to water the plant at the base, rather than from above, to prevent the water from accumulating on the leaves.
Fertilization
Fertilize Oncocalamus macrospathus Burret with a balanced fertilizer every six months. Apply the fertilizer around the base of the plant and water it in thoroughly. Avoid overfertilizing the plant, which can cause leaf scorching and other problems. Nitrogen is essential for the growth of the bamboo, so choose a fertilizer that has a higher nitrogen content. Additionally, consider using organic fertilizers, such as compost or well-rotted manure, which can enrich the soil and improve its texture.
Pruning
Prune Oncocalamus macrospathus Burret regularly to promote new growth and maintain its shape. The best time to prune is during the dry season, when the plant is dormant. Remove any dead, damaged, or diseased canes with pruning shears and cut back any overgrown or stray branches to the desired length. Additionally, trim the plant's foliage to remove any dry or yellow leaves and improve air circulation around the plant. Be sure to sterilize your pruning tools with rubbing alcohol before and after use to prevent the spread of diseases.
Propagation of Oncocalamus macrospathus Burret
Oncocalamus macrospathus Burret can be propagated through several methods such as seed germination, vegetative propagation, and dividing rhizomatous clumps.
Seed Germination
The easiest way to propagate Oncocalamus macrospathus Burret is through seed germination. To do this, collect mature fruits and extract the seeds from them. The seeds must be sown immediately as they lose viability quickly. Plant the seeds in a pot or any suitable container filled with soil mix with good drainage. The seeds need consistent moisture to germinate. Keep the container in a shady spot with temperature around 25-30°C. Germination may occur within the first few weeks, or take up to several months.
Vegetative Propagation
Another way to propagate Oncocalamus macrospathus Burret is through vegetative propagation, which involves the use of a part of the parent plant to grow a new one. The easiest way to do this is through stem cuttings. Select healthy stems about 20-30 cm long, and trim the leaves from the bottom. Dip the cut end in rooting hormone and plant it in a pot with well-draining soil mix. Maintain consistent moisture and keep the pot in a shaded location. Roots will start to develop within a month, and once the new plant establishes itself, it can be repotted in a larger container.
Dividing Rhizomatous Clumps
Oncocalamus macrospathus Burret grows rhizomatous clumps and can be propagated by dividing these clumps. To do this, carefully remove the plant from its container or the ground, and divide the clumps into smaller sections ensuring that each section has both roots and shoots. Repot or replant the sections in a well-draining soil mix, maintaining consistent moisture. Keep the pot in a shaded location until the new plant establishes.
Disease and Pest Management for Oncocalamus macrospathus Burret
Diseases:
Oncocalamus macrospathus Burret is susceptible to several diseases, including:
1. Leaf Spot: This is a fungal disease that causes small, round, yellow spots on the leaves. These spots can merge and form larger patches, which can lead to defoliation. To manage this disease, remove infected leaves and apply a fungicide.
2. Fusarium Wilt: This is a fungal disease that affects the plant's vascular system, causing wilt and dieback. It can be managed by removing infected plants and sterilizing the soil. Avoid replanting in the same location.
3. Powdery Mildew: This is a fungal disease that causes a white, powdery coating on the leaves. To manage this disease, remove infected leaves and apply a fungicide.
Pests:
Oncocalamus macrospathus Burret is susceptible to several pests, including:
1. Mealybugs: These insects are small, soft-bodied, and covered in white, waxy secretions. They can be managed by removing them by hand or applying insecticidal soap.
2. Scale Insects: These insects are small, flat, and usually found on the underside of leaves. They can be managed by removing them by hand or applying horticultural oil.
3. Spider Mites: These pests are tiny and can cause yellowing and stippling of the leaves. They can be managed by applying insecticidal soap or horticultural oil.
