Cyanea stictophylla

Cyanea stictophylla is a rare species of flowering plant in the bellflower family known by the common name Kaiholena cyanea. It is endemic to the island of Hawaii, where it is known only from the rainforests of Mauna Loa. It is a federally listed endangered species of the United States. Like other "Cyanea" it is known as haha in Hawaiian.
This Hawaiian lobelioid is a shrub or tree of the rainforest. It has become rare due to the grazing and trampling damage of cattle. There are perhaps 20 individuals remaining.
