''Globulostylis'' is a genus of flowering plants in the family Rubiaceae. It comprises 8 species growing in Central Africa.

Description

The main characters of ''Globulostylis'' are the few-flowered inflorescences with a pair of bracts at the apex of the peduncle and the style with a swelling in the lower half.

Distribution and habitat

''Globulostylis'' has 8 species in Central Africa, all endemic to the

Lower Guinean forests The Lower Guinean forests is region of coastal tropical moist broadleaf forest in West Africa, extending along the eastern coast of the Gulf of Guinea from eastern Benin through Nigeria and Cameroon. The Dahomey Gap, a region of savanna and dry for ...

, except '' G. uncinula'', which also occurs in the Congolian forests. All species are shrubs or small trees of forest understory, never gregarious.

Bacterial leaf symbiosis

Endophytic bacteria are housed in the intercellular space of the leaf mesophyll tissue. The presence of these bacteria can only be microscopically ascertained. The bacteria are identified as '' Burkholderia'', which is a genus that is also found in the leaves of other Rubiaceae species. hypothesis is that these endophytic bacteria provide chemical protection against insect herbivory.

Taxonomy

The genus was described by H.F. Wernham in 1913 to accommodate two species from South Nigeria collected by Mr. and Mrs. P.A. Talbot, viz. '' G. minor'' and '' G. talbotii''. A third species, '' G. cuvieroides'', was added later. ''Globulostylis'' and ''Cuviera'' species are closely related, and therefore at one point ''Globulostylis'' was treated as a subgenus of ''Cuviera''. However, the combined analysis of both morphological and molecular data separates both genera.
