Among the rich collections made in Indonesia by Dr A. Kostermans (Bogor, Java) during the last decennia, there is an interesting species of Convolvulaceae from Borneo. It appears to be closely related to Neuropeltis Wall, but differs by a number of important characters justifying its acceptance as the type of a new genus, Neuropeltopsis. Neuropeltopsis Ooststr., genus nov., a genere Neuropeltide differt inflorescentiis racemosis longioribus minus densis, bracteis magnis albis superne in parte inferiore florem unum gerentibus, marginibus glabris loborum corollae multo latioribus, filamentis paene totiis ad corollam adnatis, stylo uno longo in apice breviter bifurcato.
