General Information
Cyanea acuminata, a member of the bellflower family (Campanulaceae), is an unbranched shrub 0.3 to 2 m (1 to 6.6 ft) tall. The leaves, 11 to 32 cm (4.3 to 12.6 in.) long and 3 to 9 cm (1.2 to 3.5 in.) wide, are inversely lance-shaped to narrowly egg-shaped or elliptic. The upper leaf surface is green, whereas the lower surface is whitish green. The slightly hardened leaf edges contain small, spreading, pointed teeth. The leaf stalks are 2 to 10 cm (0.8 to 4 in.) long. Six to 20 flowers are arranged on a flowering stalk 15 to 60 mm (0.6 to 2.4 in.) long. The calyx lobes, 2 to 5 mm (0.08 to 0.2 in.) long, are narrowly triangular. The corolla is white and sometimes tinged purplish, 30 to 35 mm (1.2 to 1.4 in.) long and 3 to 4 mm (0.1 to 0.2 in.) wide. The tubular portion of the flower is almost erect to slightly curved, while the lobes are one-fourth to one-third as long as the tube and spreading. The yellow to yellowish orange, round berries are approximately 5 mm (0.2 in.) long.» Range Information

Habitat Requirements
Cyanea acuminata typically grows on slopes, ridges, or stream banks from 305 to 1,219 m (1,000 to 4,000 ft) elevation. The plants occur in mesic to wet Metrosideros sp. (ohia)-Dicranopteris sp. (uluhe), Acacia koa (koa)-Metrosideros sp., or Diospyros sandwicensis (lama)-Metrosideros sp. forest in lowland mesic, lowland wet, montane wet, and wet cliff ecosystems in the Koolau and Waianae mountains of Oahu.
Movement / Home Range
Historically, Cyanea acuminata was known from populations in the Koolau mountains of Oahu; however, in 2009, populations were also found in the Waianae mountains.
Reproductive Strategy
Cyanea acuminata has been observed flowering in September through March, and fruiting in March and April.
Other
Cyanea acuminata is distinguished from others in this endemic Hawaiian genus by the color of the petals and fruit and length of the calyx lobes, flowering stalk, and leaf stalks.
