Scientific classification
Genus:
Archeria (plant)
Species:
traversii

Archeria traversii is a species of shrub in the family Ericaceae.

Distribution

Archeria traversii is scattered locally across southern New Zealand (the South Island and Stewart Island), where it is endemic. It is notably absent from Marlborough and much of the eastern South Island.

Ecology

It is largely found in shrublands and conifer-broadleaf forests, at lowland to montane altitudes. Flowering takes place from December to February, and fruiting from February to April.

Morphology

Leaves
Narrow lanceolate leaves, becoming glabrous and leathery. Dark green on the adaxial side, while abaxially they tend to be much paler. The leaf apices are acute to subacute, and sometimes reddish in colour. The base of the leaf is rigid and nearly sessile, attached to the stem with a short and flat petiole. Dimensions are roughly 7–12 mm long and 2–4 mm wide. Leaf margins are entire, minutely ciliolate, and flat to slightly recurved. Prominent venation can often be seen on the abaxial sides of the leaves (3- to 5-veined).
Inflorescence
A solitary terminal raceme, with 8–16 flowers, ranging from 10–30 mm in length. The axis and short curved pedicels are both pubescent. The bracts are oblong and caducous.
Flowers & fruits
The flowers are perfect, 4–5 mm long, urn shaped, with a corolla that is white to pink to deep red in colour (often lighter at the base and darkening towards the lobes). The sepals are oblong and ciliolate, frequently light green but turning to red towards the tips. Capsules are 2–3 mm in diameter, with 3–5 locules.

Evolutionary history

The phylogeny of the genus remains unknown, but morphologically A. traversii appears to most closely resemble A. racemosa, the only other New Zealand species in the genus.

Conservation status

Archeria traversii is currently regarded as non-threatened.

Etymology

Archeria was named by Joseph Dalton Hooker in 1844 after the nineteenth-century Tasmanian botanist W. Archer. The specific epithet traversii comes from William Travers, a 19th-century New Zealand naturalist and politician, after whom the plant species was named.
