Species

Veronica macrantha var. macrantha

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'.
macrantha: big flowered

Common Name(s)

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.

Synonyms

Hebe macrantha (Hook.f.) Cockayne et Allan var. macrantha, Parahebe macrantha (Hook.f.) Heads

Distribution

Mountains of South Island, chiefly on or west of the Main Divide, from near Lake Tennyson, to the Franklin Mountains. The varieties overlap in distribution at Lake Tennyson, southern Nelson, and possibly also (not verified by specimens) at localities between there and Lewis Pass.

Habitat

It grows in penalpine grassland or low shrubland.

Features

Spreading low shrub to 0.3 (-0.5) m tall. Branches erect or spreading or decumbent, old stems mottled grey; branchlets green or red-brown or brown, glabrous or puberulent (usually only on very youngest branchlets), hairs uniform or bifarious; internodes 1-14 mm; leaf decurrencies obscure to swollen. Leaf bud indistinct and tightly surrounded by recently diverged leaves. Leaves narrowly elliptic or oblanceolate, or spathulate or sub-circular, coriaceous, slightly concave or flat, 5.5-30.2 x 2.5-13.5 mm, ratio of lamina length/width 1.2-3.3 (-3.8), distance from leaf base (including petiole) to widest point (5.1-) 10-20 (-23.2) mm,; apex subacute or obtuse; midrib not thickened, or depressed to grooved above and thickened below, sometimes evident in fresh leaves; margin glabrous or sparsely ciliolate, sometimes tinged red, deeply toothed, number of teeth on one side of leaf (2-) 3-7 (-11); upper surface green (sometimes tinged red near base), dull, with many stomata, glabrous or hairy along midrib; lower surface green, hairy along midrib (usually) or glabrous; petiole 0.5-5.4 mm. Inflorescences with 2-7 flowers, lateral, unbranched, 0.8-5.7 cm, with all flowers (including those near the apex) generally developing to maturity (but inflorescence usually terminated by a pair of empty bracts); peduncle (6-) 7-30.7 mm long; rachis 0.2-2.7 cm. Lowermost bracts on inflorescences (4-) 5-9.1 mm long, lowermost pair opposite, then subopposite or alternate above, narrowly deltoid or linear, obtuse (with a more or less squarish tip, often with a sunken apical gland). Flowers hermaphrodite. Pedicels shorter than bracts, (0.5-) 1-6 (-14.7) mm. Calyx 4.7-10.2 mm; lobes ovate or lanceolate, acuminate (with a more or less squarish tip, often with a sunken apical gland), glabrous outside (but hairy inside). Corolla tube glabrous, 4.5-5.3 x 2.5-4.5 mm (longer on anterior side), funnelform, shorter than calyx; lobes white at anthesis, ovate (often broadly), obtuse, patent to recurved, longer than corolla tube; corolla throat white or yellow. Stamen filaments thick and white, diverging slightly with age or remaining erect (and usually slightly incurved at the apex), 8-9.5 mm (varying from very shortly fused to the base of the corolla tube, to fused to the corolla lube for up to 2/3 its length); anthers creamy white or yellow, 2.6-3.5 mm. Ovary 1.6-2.5 mm; ovules 15-28 per locule, scattered on a hemispherical placenta; style 5.5-9.3 mm. Capsules angustiseptate, acute, 6.5-12.4 mm long, 4.5-6.5 mm thick, loculicidal split extending ¼-all way to base. Seeds flattened (sometimes strongly), discoid, winged, pale brown, 1.5-2.7 x 1.2-2.2 mm, micropylar rim 0.6-1 mm.

Similar Taxa

A distinctive species distinguished from other Veronica’s by its large flowers, toothed leaves, indistinct leaf bud and laterally compressed capsules. Compared to V. var. brachyphylla, V. var. macrantha has leaves narrowly elliptic or oblanceolate (not broadly elliptic); a greater distance from leaf base (including petiole) to widest point; generally a greater number of teeth on one side of leaf; longer lowermost bract on inflorescence (see each variants feature for exact measures).
