A diminutive new species of Piptospatha, P. loi P.C. Boyce and S.Y. Wong, is described from waterfalls over basalt in E Sabah. Overall, it is most similar to P. pileata S.Y. Wong and P.C. Boyce (Kalimantan Timur, obligated to shales), but differs in several features of the inflorescences and leaves. The new species is illustrated from living plants.

The most recent review of Piptospatha (Boyce & Wong 2012) recognized ten species. Since then, three additional new species from Kalimantan Timur have been identified (Boyce and Wong in press; Wong and Boyce 2012). While Wong and Boyce (2012) was still in press, a photograph sent from East Sabah alerted us to the possibility of a further undescribed species, or at least an extension to the known range of P. pileata S.Y. Wong and P.C. Boyce, but we were unable to proceed further as detailed images of the inflorescence were lacking. The spathe and spadix have now been studied, revealing that the Sabah plant, known from two localities, both on basalts, represents yet another taxonomic novelty of the genus Piptospatha. It is here described.
