The Ericaceous genus Rigiolepis was founded by Sir JOSEPH D. HOOKER (Ic. plant, third ser. II (1876), 54, pl. 1160) on a single species from Borneo, viz. R. borneensis HOOK.F. HOOKER was not quite sure about some of the characteristics, and failed to compare it with Vaccinium to which genus, indeed, several authors have reduced it. In 1914 I have discussed the Rigiolepis question (in Ic. Bog. IV, 68) in the note under Vaccinium uniflorum J. J. S. and was inclined to believe that Rigiolepis should be maintained as a distinct genus, although my material was not sufficient to solve the question definitely. Since I have studied many other species of this affinity and I do not hesitate to accept the genus.
