Cyanea grimesiana ssp. obate was collected in 1965 by John K. Obata, but not named until 1978 by Harold St. John. When the species was listed as Federally Endangered in 1994, all known populations (totaling only 18 plants at most) were located on privately owned land. (USFWS 1994)
This member of the bellflower family is generally an unbranched shrub that grows to a height of up to 10.5 feet (3.2 meters). Its stem and deeply lobed leaves are covered with tiny prickles. Flowers up to 3 in (8 cm) long grow in small clusters in leaf axils. Individual flowers range in color from purplish or greenish to yellow-white, often with magenta colored stripes or tinting. Fruits are oval shaped, orange berries slightly over an inch long.
Distribution & Occurrence
Steep, moist, shady slopes in medium to wet forests at elevations between 1,800 to 2,200 ft (550 - 670 m). (USFWS 1994)
Associated plants include both native and introduced species such as Pipturus albidus, Charpentiera sp., Claoxylon sandwicense, Pisonia sp., Acacia koa, Aleurites moluccana, Cyanea membranacea and various ferns. (USFWS 1994)
|Only 5 plants from a single population are known. There may be as many as 13 plants in two other populations; however, these populations have not been seen in the last 15 years. (USFWS 1994)|
Conservation, Ecology & Research

In April, 2002, the U.S. Fish and Wildlife Service determined that a designation of critical habitat was prudent for this species. (USFWS 2002)
