The influence of geology in the occurrence of localized species diversity and species richness of aroids on Borneo has previously been highlighted by Boyce and Wong (2013a, b, c), Ni Putu Sri Asih et al. (2012), Wong and Boyce (2011, 2012, 2013), and Wong et al (2012). Here we describe three novel species of Homalomena each restricted to one of the richest ecological habitats on the island, lowland forest over shales. Geological confirmation for this and all of our fieldwork is much assisted by Hutchison (1989, 2005) and Tate (2001).
