Hey there, Hibiscadelphus woodii . How you've been?

The plant, which is known as "Wood's hau kuahiwi" and what is thought to be extinct, is apparently still in its native Hawaii.

Three of the plants were spotted in the footsteps of the National Tropical Botanical Garden on the island of Kauai. The remote region of Kauai is known for its biodiversity, thanks to cliffs that make the region inaccessible to the humans and goats that pose a threat to local plant life.

You can see the NTBG's drone footage below, and see the plant itself (clearly marked) at roughly the halfway point.

The H. woodii plant – a relative of hibiscus – was discovered in 1991 by NTBG in 1995. It has not been seen since 2009,

The NTBG H. woodii as "a shrub or small tree and produces bright yellow flowers which turn purplish-maroon as they age."

By using a drone, NTBG researchers were able to investigate the otherwise unreachable cliffside location in. Researchers' efforts to aid the plant's propagation – which have included "grafting, tip cuttings, and attempts at cross-pollination." the Kalalau Valley.

"Drones are unlocking a treasure trove of unexplored cliff habitat, and while this may be the first discovery of its kind, I am sure it will not be the last, "NTBG's Ben Nyberg said in a statement.
