Sertulum Papuanum 20 The Boraginaceae of the Alpine Regions of New Guinea

Abstract

In the alpine flora of New Guinea the Boraginaceae occupy a small place with only three genera, Cynoglossum, Myosotis, and Trigonotis, and a problematical fourth one, Crucicaryum, being reported. In the present treatment descriptions of genera and species are given with localities, collectors, and ecological notes. The genus Trigonotis is given in its entity, including all species in New Guinea outside the alpine region. Two new species, T. culminicola and T. vestita, are described.
