Centroplacaceae Plant Family

About the Centroplacaceae or Centroplacus Family

Centroplacaceae is a family of flowering plants that consists of a single genus, Centroplacus. These trees are native to tropical regions of Africa and South America, with a few species occurring in Central America and Mexico. The family was first described in 1900 by the German botanist Ignatz Urban, who placed it in the order Celastrales. However, its precise relationship to other families within the order remains unclear.

Centroplacaceae trees are known for their unique wood anatomy, which distinguishes them from all other flowering plants. They have uniseriate rays, which are rows of cells stretching from the center of the tree to the bark, that are oriented vertically rather than horizontally as in most other trees. This gives the wood a distinctive appearance and makes it highly valued for decorative purposes.

Despite their ecological and economic importance, Centroplacaceae trees are not well- and many aspects of their biology and ecology remain poorly understood.

Taxonomy and Classification

Centroplacaceae is a family of flowering plants in the order Celastrales. The family consists of only one genus, Centroplacus, which contains about 30 species of trees.

The order Celastrales includes around 100 genera and approximately 1, species. It is a diverse group of woody plants that are distributed throughout the world, but with the majority found in tropical regions.

Within the family Centroplacaceae, there are no subfamilies or major groups recognized at present. However, Centroplacus is thought to be closely related to other families within Celastrales, such as Lepidobotryaceae, Brexiaceae, and Hippocrateaceae.

Centroplacaceae trees are characterized by their unique wood anatomy, which features uniseriate rays oriented vertically rather than horizontally, distinguishing them from all other flowering plants. They also have opposite leaves and small flowers that are arranged in clusters at the end of branches.

Morphology and Characteristics

Centroplacaceae trees are known for their distinctive morphology, which includes highly valued wood anatomy. These trees are medium- to large, with most species growing to between 10 and 25 meters tall, though some can reach up to 50 meters in height.

The leaves of Centroplacaceae trees are simple and opposite, typically with a short petiole and serrated margins. The venation pattern is pinnate, with prominent veins that run parallel to the midrib. The leaves are deciduous in some species, while others may retain their leaves year-

Centroplacaceae flowers are small and inconspicuous, arranged in clusters at the end of branches. They consist of four or five sepals and petals, with male and female flowers often found on separate trees (i. dioecious).

Centroplacaceae trees are most well- for their unique wood anatomy, which distinguishes them from all other flowering plants. The wood has uniseriate rays that are oriented vertically rather than horizontally, giving it a distinctive appearance. The wood is durable and hard, making it highly valued for decorative purposes and for use in construction and furniture-

Distribution and Habitat

Centroplacaceae trees are found in tropical regions of Africa and South America, with a few species occurring in Central America and Mexico. The majority of the genus Centroplacus is native to tropical rainforests in the Amazon basin, where they play an important role in the ecology of the region.

In Africa, Centroplacaceae species are found primarily in West and Central Africa, ranging from Guinea to Cameroon and Congo. They are often found growing along rivers or in lowland forests, where they can reach impressive heights.

Centroplacaceae trees require warm and humid climates to thrive and are adapted to a wide range of soil types. However, they are most commonly found in soils that are well- and rich in organic matter.

Despite their ecological and economic importance, Centroplacaceae trees remain poorly studied, and many aspects of their distribution, ecology, and biology remain poorly understood.

Economic and Ecological Importance

Centroplacaceae trees are economically and ecologically important in the regions where they occur. They are highly valued for their unique wood anatomy, which makes them desirable for decorative purposes, construction, and furniture-

In Africa, Centroplacaceae trees are used locally for a variety of purposes, including as timber for construction, fuelwood, and medicine. Several species are also used in traditional healing practices to treat a variety of ailments, such as malaria and stomach pains.

Centroplacaceae trees play an important ecological role in tropical rainforests, where they provide habitat for a variety of animals, including birds, primates, and insects. They also contribute to the overall biodiversity of these ecosystems and help to maintain the health and function of the forest ecosystem.

Despite their importance, many Centroplacaceae species are threatened by habitat loss and overexploitation for their valuable wood. Several species are considered endangered or vulnerable, and conservation efforts are needed to protect these important trees from further decline.

Notable Species

Some notable species within the family Centroplacaceae include:

  1. Centroplacus angolensis: This species is native to Angola and is known for its valuable wood, which is used for construction and furniture- It is a medium- tree, reaching up to 20 meters in height.

  2. Centroplacus glaucinus: This species is found in tropical rainforests in Central and South America and is known for its distinctive blue- leaves. It is a large tree, growing up to 50 meters tall.

  3. Centroplacus orbicularis: This species is found in West Africa and is known for its round or oval- leaves that are highly variable in size. It is used locally as timber and for medicinal purposes.

  4. Centroplacus robustus: This species is found in tropical rainforests in South America and is known for its large, edible fruits that are an important food source for local communities. It is a large tree, reaching up to 40 meters in height.

  5. Centroplacus syncephalus: This species is found in the Amazon basin and is known for its unique inflorescence, which consists of multiple flowers fused together into a single structure. It is a small to medium- tree, growing up to 20 meters tall.

Many Centroplacaceae species are threatened by habitat loss and overexploitation, and several are listed as endangered or vulnerable by the International Union for Conservation of Nature (IUCN). Conservation efforts are needed to protect these important trees from further decline and ensure their long- survival.
