In the group of species with H. obscura and H. subalpina, a number of fruiting specimens could not be assigned satisfactorily to any of the known taxa. More information on their affinities can only be obtained from male flowering specimens which have vegetative characters closely matching those of the fruiting material. These fruiting collections have been discussed under H. obscura by De Wilde (I.e., 1986: 44 & Blumea 32, 1987: 469).
