Hawaii (NNA) American scientists saw a plant with a drone which globally declared extinct. The National Tropical Botanical Garden is locating in a mountainous area of the Kauai(Island in Hawaii). Kauai is famous worldwide for rare trees, plants, herbs, and living creatures. Scientists are trying to protect this island. One of these plants is Hibiscadelphus woodii, which exist in the valley of Kalalau. This area is mountainous and dangerous that’s why scientists got the help of a drone. When the experts oversaw, they identify this plant surprisingly. In 1991, a botanist of the same Institute saw this plant and incorporated in 1995 as a new type of plant. Since then it was not found anywhere in the world by 2009 and experts finally declared this plant as extinct.
