Cleomaceae is a family of flowering plants that belongs to the order Brassicales. It is a relatively small family, comprising about 300 species distributed across 10 genera. The most well-known genus within this family is Cleome, which is often referred to as spider flowers due to their distinctive appearance. Cleomaceae has a wide distribution, with species found in tropical, subtropical, and temperate regions worldwide.

Description

Plants in the Cleomaceae family are mostly herbaceous in nature, with a few shrubs and small trees also present. They are characterized by their simple or palmately compound leaves, which are usually arranged alternately along the stem. The flowers of Cleomaceae species are typically arranged in racemes and are known for their radial symmetry. They possess four to six petals, often brightly colored, which makes them attractive to a variety of pollinators. The fruit of Cleomaceae plants is usually a capsule or a pod, containing several seeds.

Taxonomy

The classification of the Cleomaceae family has undergone significant changes over the years. It was previously included in the family Capparaceae, but genetic studies have led to its recognition as a separate family within the Brassicales order. The family is closely related to the Brassicaceae (mustard family) and Capparaceae (caper family), with which it shares several morphological and genetic traits.

Genera

The Cleomaceae family includes the following genera, among others:

• Cleome - The most well-known and widely distributed genus, including the popular garden plant, spider flower (Cleome hassleriana).
• Gynandropsis - Known for the showy Gynandropsis gynandra, also called spider wisp.
• Tarenaya - Includes species formerly classified within Cleome.

Distribution and Habitat

Cleomaceae species are found in a wide range of habitats, from tropical rainforests to arid deserts. They are adaptable to various environmental conditions, which has contributed to their wide distribution. While some species are native to specific regions, others have been introduced and naturalized in different parts of the world.

Uses

Several species within the Cleomaceae family are of economic importance. Some, like Cleome gynandra, are cultivated as leaf vegetables in Africa and Asia. Others are grown as ornamental plants in gardens for their attractive flowers and foliage. Additionally, some species have been used in traditional medicine for their purported health benefits.

Conservation

The conservation status of Cleomaceae species varies widely. While many species are common and not considered at risk, others are rare and face threats from habitat loss, invasive species, and climate change. Conservation efforts are necessary to protect these vulnerable species and their habitats.
