A new species of Urtica from the Papuan highlands and an emended distinction of Urtica urens and dioica

Among the duplicate specimens collected by Dr. L. J. Brass, recently received, there is a collection of an Urtica which roused the attention of Dr. Van Steenis, because of the facts that it is the first collection of the genus in New Guinea and that it was collected in a completely uninhabited, remote spot at high altitude, which makes it almost certain that it is indigenous. Another argument, pointing in the same direction was, that it did not fit either U. mens L. or U. dioica L. I was delighted to be allowed to try to find the identity of this plant. One should of course in such a case, after careful examination of its characters try to correlate it with species described or recorded from Malesia and adjacent regions. Within Malesia only U. bullata Bl. occurs which is a quite different species. Among the Asian and Japanese species none fits, according to the descriptions.
