Description of Calpocalyx aubrevillei Pellegr.
Calpocalyx aubrevillei Pellegr. is a tree species that belongs to the family of botanical plants Chrysobalanaceae. It is commonly known as "Okoumé" in Cameroon, where it is originally from. The tree species can grow up to 50 meters high and 2 meters in diameter. It is widely acknowledged for its economic and medicinal values. The Okoumé tree is prevalent in West and Central Africa, particularly in Gabon, Congo, and Cameroon.
General Appearance
The tree features beautiful foliage and has a dense, dome-shaped crown. The bark of the Okoumé tree is gray and has a rough texture. The leaves are shiny, dark green, and range from 4 to 12 centimeters in length. The flowers are small, white, and are grouped in panicles, while the fruit is round, edible and measures between 1 to 2 centimeters in diameter.
Uses
The Okoumé tree has a vast range of uses, making it an essential species. Its timber is often used in the construction of marine and aviation vessels like yachts and airplane models. It is also used in furniture making, interior decoration, and panelling. Additionally, the Okoumé tree is valuable in the production of plywood sheets and veneers due to its uniform texture and strength.
In the medical field, Okoume leaves, and bark extracts are used in wound dressing and the treatment of peripheral arterial disease. The leaves are also incorporated in some traditional practices to treat diseases like malaria.
Furthermore, the tree species plays a crucial role in the environment due to its high carbon fixation, thus reducing global carbon dioxide levels. It is also an essential habitat for a wide range of animal species such as birds, squirrels, and monkeys.
The Okoumé tree, therefore, is a significant economic and ecological asset in the regions in which it grows.
Growth Conditions for Calpocalyx aubrevillei Pellegr.
Calpocalyx aubrevillei Pellegr. is a tropical plant species native to Cameroon and Gabon in Central Africa. It is commonly known as 'Mbola' in the local language. This species thrives well in the natural tropical rainforest ecosystem. To grow the plant successfully, several growth conditions need to be considered. These include light, temperature, and soil requirements.
Light Requirements
The plant prefers moderate to bright light exposure. This means that it should be situated in a location that receives about four to six hours of indirect sunlight in a day. Direct sunlight exposure should be avoided as it may cause scorching of the leaves. Mbola trees grow well both in shade and sun, but it's recommended to plant them in partially shaded areas to reduce light stress and promote healthy growth.
Temperature Requirements
The Calpocalyx aubrevillei Pellegr. grows best in warm tropical conditions. The ideal temperature range for its growth is between 18°C to 28°C (65°F to 82°F). Temperatures outside this range may slow down or halt plant growth. The plant should be protected from frost, wind, and cold drafts as they can cause leaf discoloration, defoliation, and death.
Soil Requirements
The Calpocalyx aubrevillei Pellegr. tree prefers well-drained soils rich in organic matter content. The soil should be slightly acidic, with a pH range of 5.5-7.5. Mbola trees can tolerate damp soil conditions, but they do not do well in waterlogged or poorly-drained soils. Ensure you plant the tree in a deep hole that is wider than the root ball to give it enough space to expand and grow healthy and strong.
In conclusion, successful cultivation of Calpocalyx aubrevillei Pellegr. involves providing the appropriate growth conditions, including moderate to bright light exposure, warm tropical temperature, and well-drained soils rich in organic matter. With proper care and maintenance, you can expect to enjoy its elegant beauty for many years to come.
Cultivation
Calpocalyx aubrevillei, also commonly known as the Aubreville's Calpocalyx, is a plant that requires a warm and humid environment to thrive. It is best grown in tropical or subtropical regions, and it prefers well-draining soil with a pH of 5.5 to 7.2.
The plant can be propagated through the use of seed or by vegetative cuttings. Cuttings can be taken during the growing season, and they should be planted in a well-draining soil mix. The cuttings should be kept moist, but not waterlogged, until they have developed roots.
Watering Needs
Calpocalyx aubrevillei requires consistent moisture in the soil, but it does not tolerate waterlogged conditions. It is best to water the plant deeply once a week or whenever the top inch of soil feels dry to the touch. During the growing season, the plant may require more frequent watering to support its growth and development.
Fertilization
To promote healthy growth, Calpocalyx aubrevillei should be fertilized regularly during the growing season. A balanced fertilizer with a ratio of 10-10-10 or 20-20-20 can be used. Fertilizer should be applied every two weeks, or as instructed on the fertilizer package.
It is important to avoid over-fertilizing, as this can lead to salt build-up in the soil and damage the plant. It is also recommended to reduce fertilization during the winter months, as the plant's growth is typically slower during this time.
Pruning
Calpocalyx aubrevillei does not require extensive pruning, but trimming back any dead or damaged leaves and stems can help promote healthy growth. Pruning can also be done to control the size and shape of the plant.
Pruning should be done in the spring or summer months, and care should be taken to avoid cutting back too much of the plant at once. It is recommended to prune no more than one-third of the plant's foliage at a time.
Propagation of Calpocalyx aubrevillei Pellegr.
Calpocalyx aubrevillei Pellegr. can be propagated through two methods:
1. Seed Propagation
Seeds of Calpocalyx aubrevillei Pellegr. can be used for its propagation. The following steps may be followed for seed propagation:
- Collect the matured seeds from the plant.
- Clean the seeds and soak them in water for 24 hours.
- Sow the seeds in a well-draining potting mix.
- Keep the pot in a warm and moist place, away from direct sunlight.

2. Stem Cutting Propagation
Stem cuttings of Calpocalyx aubrevillei Pellegr. can also be used for its propagation. The following steps may be followed for stem cutting propagation:
- Select a healthy stem from the parent plant, preferably one that is about 4-6 inches long.
- Cut the stem just below a node using a clean and sharp knife.
- Remove the leaves from the bottom half of the stem.
- Apply a rooting hormone to the cut end of the stem.
- Pot the stem in a well-draining potting mix.
- Keep the pot in a warm and moist place, away from direct sunlight.
- Water regularly to keep the soil moist.
- Roots will develop in 2-3 weeks, and new growth will appear.
- Transplant the young plant to an individual pot when it is large enough to handle.
