Plants of Hawaii Volcanoes National Park

Scientific Name Vaccinium calycinum Sm.
Family Ericaceae (Heath family)

Other Names Tree `ohelo, Hawaiian: `ohelo, `ohelo kau la`au (transl. "`ohelo placed on trees")
Status Endemic
Distribution & Habitat 500 - 1,800 m; all the main islands except Ni`ihau and Kaho`olawe.

Terrestrial or sometimes epiphytic, in wet forests and bogs (Wagner, et al. 1990: 593)

Locations in this Guide Thurston Lava Tube
General Appearance
These are stiffly erect shrubs that are 1 to 5 m tall (Wagner et al. 1990: 593) that are found most often in the wet forests (Stone and Pratt 1994: 195).

This is a common understory shrub where it is found as scattered individuals (Stone and Pratt 1994: 195).

Unlike the related V. reticulatum, this species is not recognized as easily by its bright fruit since they tend to occur in smaller numbers on much larger plants.

Leaves
The leaves are quite variable in shape.  One distinguishing character that will separate this from the other red-berried species in the same wet-forest habitat (Coprosma ochracea) are the teeth along the edge of the leaf.

The leaves are bright green and quite large (5 to 8 cm long and 2 to 4 cm wide) (Wagner et al. 1990: 593).

The leaves are deciduous, with young plants retaining their leaves for several years (Wagner et al. 1990: 593).

Flowers & Fruits
The flowers are distinctive by having ovate calyx lobes longer than the tube at anthesis (Wagner, et al. 1990: 593).

The flowers are relatively inconspicuous and their color varies from greenish to red (Stone and Pratt 1994: 195).  They range from 9 to 12 mm long (Wagner, et al. 1990: 593).

The berries are bright red.  They resemble their well-known relatives, the blueberries and cranberries.  They range in size from about 9 to 15 mm in diameter.  They have small but numerous seeds (Wagner, et al. 1990: 593).

These berries are edible but are more tart tasting than the more often eaten V. reticulatum (Stone and Pratt 1994: 195).
