None of the three collections studied has inflorescences or fruits. The foliar characters of the collection made by Korthals are remarkably similar to R. acuminata. The leaves (including the pul-vini) in the other two collections (made by De Vo-gel and Teijsmann) of R. grandifolia are much thicker than in R. acuminata. According to Radl-kofer, R. grandifolia has sessile fruits, in contrast with R. acuminata whose fruits are distinctly stipi-tate. Also, the pulvini of R. grandifolia are 'bulbously thickened' and not normally thickened as in R. acuminata. This character cannot be observed in the Korthals-collection.
Although I doubt whether R. grandifolia can be separated from R. acuminata, the absence of flowers and fruits in the specimens studied keeps me from concluding that R. grandifolia and R. acuminata are conspecific.
