Iris is a flowering plant genus of 310 accepted species with showy flowers. As well as being the scientific name, iris is also widely used as a common name for all Iris species, as well as some belonging to other closely related genera. A common name for some species is flags, while the plants of the subgenus Scorpiris are widely known as junos, particularly in horticulture. It is a popular garden flower.

Platanthera elegans is a species of orchid known by several common names, including elegant piperia, coast piperia, hillside rein orchid, and hillside bogorchid. This is a showy flowering plant native to western North America. It grows from a caudex tuber and sends up a thick stem just under a meter in maximum height. The stem is topped with a cylindrical spike inflorescence of densely packed flowers with curving white to greenish-yellow petals. Coastal individuals are noticeably thicker and have more flowers than those that grow further inland; it is uncertain if these are variants, subspecies, or even separate species. They are both currently treated as P. elegans. Other species of Plantanthera, notably the endangered species P. yadonii are quite similar in appearance to some populations of this species.

Veronica wormskjoldii is a species of flowering plant in the plantain family known by the common name American alpine speedwell. It is native to much of northern and western North America, including the western United States and northern Canada, from where it grows in moist alpine habitat, such as mountain forest understory.

The expedition was manifestly to collect specimens for the Flora Danica and was financed by Wormskjold's father, though Hornemann sponsored chancery secretary Friedrich Gustav Heiliger (c.1789-) as botanical draftsman, paid for by the royal treasury. He stayed in Nuuk and in the vicinity of Qaqortoq and was helped to collect the plant specimens by the local Greenlandic population, which Wormskiold described.
