New material of Knema and Myristica necessitated the description of some new species, subspecies and forms, viz. Knema korthalsii subsp. rimosa, K. kunstleri subsp. pseudostellata. K. latericia subsp. ridleyi forma nana and forma olivacea, K. minima, K. tridactyla subsp. pachydactyla and subsp. salicifolia, and Myristica inaequalis and M. rosselensis subsp. minuliflora. Additional comments to other taxa are given and, where appropriate, insertion in (earlier published) general and regional keys are proposed.
