In 2016 during a survey for potential fencing of the Ha'akoa unit on windward Mauna Kea, Hawai'i Island (Hawaiian Islands) a single plant of the genus Schiedea was discovered. No species of the genus had ever been known to occur in this area, and only three species of Schiedea were known previously from Hawai'i Island. Two are vining species and the third is a coastal subshrub. The single plant obviously represented an interesting find, and because the plant was vegetative another visit was scheduled to collect a flowering specimen, but by then the plant had died. Soil taken from the site with seeds in the soil produced two plants, one of which flowered in cultivation in 2021. A study of this individual indicated it was a member of Schiedeasect.Mononeura, characterized by erect to ascending habit, quadrangular stems, seeds not persistent on the placenta and readily dispersing from the dehisced capsule, and flowers facultatively autogamous. With the discovery of this new species there are 35 species in this Hawaiian endemic genus.
