jakajia

Jakajia is a genus of flowering plants in the family Rubiaceae. The genus was described in 1919 by Paul Hermann Wilhelm Taubensee, and the type species is Jakajia calcicola. These plants are native to Madagascar.

Species within the genus Jakajia are typically shrubs or small trees. They are characterized by their opposite leaves, often ovate to elliptical in shape, and their inflorescences which can be terminal or axillary. The flowers are generally small and inconspicuous, with a corolla that is typically white or cream-colored. The fruit is usually a capsule.

Jakajia species are found in various habitats within Madagascar, including dry forests and limestone formations. Their distribution is often localized, making them of interest to botanists studying the island's unique flora. Conservation status varies among species, with some potentially facing threats due to habitat loss. Further research is ongoing to fully understand the taxonomy and ecological roles of the plants within the Jakajia genus.
