ABSTRACT Bau djinna is described as a new species from Central Sarawak and compared with three species to which it is most similar. Recognition of B. djinna takes the genus to 27 species, 25 of which are endemic to Borneo. A brief note is provided on Schismatoglottis ambigua , a recently published name synonymous with Bau inculta . The paper also introduces the term ‘anthomorph’ for the flowering structure that in general is termed an inflorescence in the Araceae and explains why the term ‘bloom’ that the authors have employed previously is unsatisfactory.
