Nototrichium divaricatum, also known as Na Pali rockwort or kuluʻī (Hawaiian), is a rare perennial shrub in the pigweed family, Amaranthaceae, that is endemic to the island of Kauaʻi in Hawaiʻi.

[4] Nototrichium divaricatum is mainly found on the north-facing cliffs and ridges of Kaua'i, particularly in the Hanalei District and Na Pali coast.

[4][5] The primary challenges facing Nototrichium divaricatum include damage and habitat loss due to the activities of feral goats, which threaten many endemic species throughout Hawai'i.

[4] Effective conservation strategies aimed at managing feral animal populations and controlling invasive plants are crucial for the survival of this rare species.

Preserving this endemic species contributes to ecological diversity and sustaining the cultural traditions connected to Hawai'i’s native flora.
