Cyanea grimesiana ssp. obatae


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

State Range
  Hawaii
State Range of  Cyanea grimesiana ssp. obatae
Habitat
  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)

Distribution
  Grows only in the Waianae Mountain Range on the island of Oahu, Hawaii.

Number Left
  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

Ecological Relationships
  None known.

Threats
  As stated by the USFWS in 1994 when the plant was officially listed as Endangered, threat to the species include:
Competition from alien (weedy) plants
Predation of seeds or fruits by introduced slugs
Feral pigs that degrade habitat
Random extinction
Reduced reproductive vigor due to small number of living individuals
Illegal collecting of plants for scientific or horticultural purposes
Excessive visits by individuals interested in seeing rare plants (as a result of increased publicity)

Current Research Summary
  Tissue culture work is being done at the Lyon Arboretum on Oahu. (Sugii 2001)

Current Management Summary
  There are currently no live plants growing at the Honolulu Botanical Gardens.

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

Research Management Needs
  Information on susceptibility to diseases and pests.
Symbiotic relationships, if any.
Soil and water relationship information.

Ex Situ Needs
  Propagation and plant maintenance information.
