Abstract
During the preparation of the Vascular Flora of the Marquesas Islands a new endemic species of Heliotropium L. (Boraginaceae) has come to light and is described herein: Heliotropium perlmanii Lorence & W. L. Wagner. It is known only from the island of Eiao and appears most closely related to Heliotropium marchionicum Decne., also endemic to the Marquesas and known from Nuku Hiva. An amended description of Heliotropium marchionicum and key to separate the Marquesan species are given and their differences discussed.

The Flora of the Marquesas Islands project is a collaborative program primarily between the Smithsonian Institution and the National Tropical Botanical Garden intended to further knowledge of the flora of this remote archipelago
Study of Heliotropium collections for preparation of the Vascular Flora of the Marquesas Islands has revealed that the collections from Eiao differ from H. marchionicum in a number of significant, non-overlapping morphological features including branching of the stems, indument, phyllotaxis, characters of the flowers, including the annular stigma overtopped by a sterile, conically elongated stigmatic column, and fruits
