Species

Veronica benthamii

Etymology

Veronica: Named after Saint Veronica, who gave Jesus her veil to wipe his brow as he carried the cross through Jerusalem, perhaps because the common name of this plant is 'speedwell'. The name Veronica is often believed to derive from the Latin vera 'truth' and iconica 'image', but it is actually derived from the Macedonian name Berenice which means 'bearer of victory'.
benthamii: Named in honour of George Bentham (1800 - 1884), considered the most prolific botanist of the nineteenth century.

Common Name(s)

Benthams Hebe

Conservation status of New Zealand indigenous vascular plants, 2012
The conservation status of all known New Zealand vascular plant taxa at the rank of species and below were reassessed in 2012 using the New Zealand Threat Classification System (NZTCS). This report includes a statistical summary and brief notes on changes since 2009 and replaces all previous NZTCS lists for vascular plants. Authors: Peter J. de Lange, Jeremy R. Rolfe, Paul D.

Distribution

Endemic. New Zealand: Auckland and Campbell Islands

Habitat

Coastal to montane. Usually on peat amongst Chionochloa antarctica tussocks and shield fern (Polystichum vestitium). Sometimes grows around boulder and rock outcrops.

Features

Bushy or spreading shrub up to 1 × 1 m. branches decumbent or ascending; branchlets pubescent or glabrous, if hairy then hairs white, bifarious or occasionally uniform; internodes 1.0-13.0-15.6 mm; leaves abscising at nodes. Leaf bid obscured by surrounding leaves, leaves usually overtopping bud. Leaves connate, erecto-patent to reflexed; lamina elliptic or obovate, coriaceous, flat, 10.0-33.0 × 3.5-14.5 mm; apex obtuse or truncate; midrib thickened below and depressed above; margin conspicuously puberulent, shallowly to deeply toothed; upper surface green, glabrous to hairy along midrib or hairy toward base. Inflorescences 11-30-flowered, mostly terminal, unbranched or with 3 or more branches (up to 4 lateral branches but never compound branching); peduncle 8-19 mm; rachis 16-93 mm. Bracts opposite and decussate, mostly free rarely connate, usually obovate sometimes elliptic, apex surmounted with a prominent gland, obtuse or subacute, occasionally emarginate. Flowers blue on pedicels 1-4 mm long, these hairy or glabrous. Calyx 3.0-8.5 mm, 4-6-lobed; lobes oblong or obovate, obtuse or subacute with a prominent apical gland, eglandular ciliate (hairs white, long and tangled), glabrous externally, hairy inside. Corolla tube 2.0-3.2 × 3.5-3.9 mm, cylindric, somewhat dorso-ventrally compressed, glabrous, < calyx; lobes 4-6, sky-blue or violet at anthesis, darkening to blue with age, obovate to circular, obtuse (posterior occasionally emarginate), erect to patent, > corolla tube; corolla throat blue or white. Stamen filaments blue, erect, 1.0-1.5 mm; anthers blue, 1.2-1.6 mm. Ovary 1.8-2.3 mm, 2-3-locular; style 2.1-3.2 mm. Capsules latiseptate (2-locular) or turgid (3-locular), subacute, 4.5-6.0 mm, hairy, septicidal splits sometimes extending only ¾-way to base, loculicidal split extending ¼-¾-way to base (usually < ½-way). Seeds 1.2-1.9 × 1.3-1.6 mm, straw-yellow or dark brown, strongly flattened, broad ellipsoid to discoid, winged.

Similar Taxa
