Fasciaba

Fasciaba is a genus of flowering plants in the family Rubiaceae. The genus was described in 1981 by Jean-François Leroy. Fasciaba species are native to Madagascar. They are shrubs or small trees. The genus is characterized by its inflorescences which are fascicles, meaning they are borne in dense clusters. The flowers are typically small and white.

The genus Fasciaba is closely related to other Madagascan genera within the Rubiaceae family, such as Carinta and Brocchiia. Phylogenetic studies have helped to clarify the relationships between these genera. The exact ecological roles of Fasciaba species are not extensively documented, but like other plants in their habitat, they likely contribute to forest structure and provide resources for local fauna.

There are a few recognized species within the genus Fasciaba. These include Fasciaba ultramontana and Fasciaba orientalis, among others. Each species may have specific distribution patterns within Madagascar. Conservation status for these species can vary, with some potentially facing threats due to habitat loss, which is a common concern for many endemic Malagasy plants. Further research into their specific habitats, reproductive biology, and ecological interactions would provide a more complete understanding of the genus.
