Pavetta is a genus of flowering plants in the family Rubiaceae. It comprises about 360 species of trees, evergreen shrubs and sub-shrubs. It is found in woodlands, grasslands and thickets in sub-tropical and tropical Africa and Asia. The plants are cultivated for their simple but variable leaves, usually opposite but also occur in triple whorls. The leaves are often membranous with dark bacterial nodules. Pavetta has small, white, tubular flowers, sometimes salviform or funnel-shaped with 4 spreading petal lobes. The flowers are carried on terminal corymbs or cymes.[1]

Gousiekte

Two Pavetta species, Pavetta harborii and Pavetta schummaniana, harbor endophytic Burkholderia bacteria in visible leaf nodules and are known to cause gousiekte, a cardiotoxicosis of ruminants characterised by heart failure four to eight weeks after ingestion of certain rubiaceous plants.[2]
