Bidens cosmoides, commonly known as the cosmosflower beggarticks,[1] is a species of flowering plant in the sunflower family. It is endemic to mixed mesic forests at elevations of 2,000–3,000 ft (610–910 m) on the island of Kauaʻi in Hawaii.[3] This particular member of the genus Bidens is far larger than its relatives and is pollinated by birds.
Unlike its smaller relatives, collectively called kokoʻolau or koʻokoʻolau in the Hawaiian language, B. cosmoides is so conspicuous and distinct that it was given a distinct name by the locals: poʻola nui ("grand poʻola"). This refers to the fact that the leaves and habitus of B. cosmoides somewhat resemble the poʻola (Claoxylon sandwicense) but unlike that plant, poʻola nui bears spectacular yellow flowers.
This plant is found only along the island's Mohihi Trail.[1] It is threatened by habitat loss due to the spread of invasive weeds and brushfires. It has also been adversely affected by the disappearance of Hawaiian honeycreeper species that pollinate it.”

Solanum sandwicense is a rare species of flowering plant in the nightshade family known by the common names Hawai'i horsenettle[2] and popolo 'aiakeakua. It is endemic to Hawaii, where it occurs today on the islands of Kauai and Oahu. It is threatened by the destruction and degradation of its habitat. It is a federally listed endangered species of the United States.
This plant is a shrub growing up to 5 meters tall with a stem up to 15 centimeters in diameter. It is coated in yellow-brown hairs. The leaves are oval, sometimes lobed, and measure up to 15 centimeters long by 14 wide. The inflorescence is an array of flowers each 2 to 2.5 centimeters in diameter. They are purple-tinged white in color and have yellow anthers. The fruit is a juicy black spherical berry just over a centimeter wide.[1]
The species is extirpated from Hawaii. The last wild individual on Oahu died in the 1990s. Its seeds have been used to propagate more plants which were then outplanted in appropriate habitat. There are no more than 20 individuals remaining on Kauai.[3]
The plant is threatened by feral pigs, feral goats, and mule deer. It is eaten by rats and slugs. The invasion of introduced species of plants such as Kalanchoe pinnata (air plant) and Passiflora tarminiana (banana poka) degrades the habitat.[3]”

“Cultural Uses: There are no known cultural uses for this particular plant. However, there is another more commonly known popolo plant (Solanum americanum) that is highly valued for its medicinal uses. I wouldn’t use this plant in any manner as you would the other popolo, since the translation of popolo’aiakeakua literally means “the popolo eaten by the god,” and that doesn’t sound like a good thing if you’re human.
Distribution: Extremely rare. This native Hawaiian plant is only known to exist in the mesic forests of Oahu and Kauai; however, its natural population on Oahu is now considered to be extinct. Luckily, seeds were harvested before the last plant died, so now there are a few plants left in cultivation and a handful planted back into the wild.”
