Trahvidaceae

Trahvidaceae is a small family of flowering plants that currently includes two genera, Trahvida and Trahvidella. The group is known from tropical regions in Africa and southern Asia and is represented mainly by woody shrubs and small trees. Members tend to have simple, alternately arranged leaves and flowers that are actinomorphic, with a standing ovary and a five-parted calyx and corolla. The fruit is typically a dry capsule that dehisces to release seeds, which in some species are adapted for wind dispersal.

Genera within the family are distinguished by subtle floral and fruit characters, as well as leaf shape and venation patterns. Trahvida genera species generally show evergreen foliage, while Trahvidella species may occur in more seasonally dry habitats. In both genera, flowers are usually solitary or appear in small inflorescences, and nectar production is modest, suggesting specialized or generalist pollinators depending on the local flora.

Distribution and habitat are primarily tropical forest margins, riverine belts, and semi-deciduous woodlands. The plants often tolerate a range of light conditions, from partial shade to full sun, and some species can cope with modest soil moisture fluctuations. Ecologically, Trahvidaceae species participate in local pollination networks and contribute to the understory plant community structure. Seed dispersal is commonly wind-assisted for some species, while others rely on gravity or brief fruit exposure in disturbed habitats.

Taxonomically, Trahvidaceae has been variably placed in older classifications near other small tropical families, with modern approaches emphasizing molecular data to clarify relations within the broader clade of flowering plants. The name derives from the type genus Trahvida, with the customary suffix -aceae.

References and further reading on Trahvidaceae remain limited, reflecting the family’s relatively sparse representation in herbaria and field studies.
