1 Knema matanensis seems related to species in the group of K. glauca (with, e.g., K cinerea, K glauca, and K. kinabaluensis); it seems particularly related to K kostermansiana, a species also with small globose male buds, and the bracteole apically on the pedicel, but differing in membranous leaves with cordate base, 8-10 anthers, and caducous bracteole. 2 Knema matanensis (and K. stellata subsp. minahassae) was not seen in the area with ultrabasic rock south of Lake Matano, where K. celebica exclusively was found.
