Zone: New Zealand
Description
This species is from New Zealand, from the South Island: Nelson (common in western Nelson from Mount Burnett southwards and west of the Motueka River), Westland (Glasgow Range), Sounds Nelson (one population at Roding River, Bryant Range). It grows in rocky places on riverbanks and gorges to rock outcrops and open places in grassland and forest margins, from lowland to sub-alpine and penalpine altitudes. It grows often on calcareous rocks. Recorded elevations range from 40 to 1538m. The epithet albicans means becoming white, as a reference to the glaucous leaves.

Botanical Description
This is a low or bushy shrub to 1m tall. The stems are decumbent to erect, or sometimes pendent, eglandular-puberulent to pubescent, hairs bifarious to uniform, or sometimes tufted between leaf bases and in axils, glabrous with age.
The leaf bud is distinct, its leaves are appressed at margins until they are fully grown. The sinus is absent. The leaves are opposite-decussate, erect-patent to recurved. The lamina is coriaceous, linear-lanceolate to lanceolate or ovate to elliptic or oblong, 11-42mm long, 3-17mm wide, dull and glaucous above and beneath. The midrib is evident. The 2 lateral veins are visible at least when fresh. The surfaces are glabrous, or sometimes eglandular hairs along midrib above especially near base. The margin is glabrous, entire. The apex is obtuse to acute or weakly plicate-acuminate; base cuneate to truncate or cordate and amplexicaul. The petiole is absent.
The inflorescence is a lateral raceme, 17-55mm long. The flowers are crowded, 15-45, all bisexual. The bracts are alternate or in irregular whorls, lanceolate, elliptic, or ovate, smaller or larger than the pedicels. The pedicels are erect-patent to spreading, 0.5-3.5mm, rarely to 6.0mm long, eglandular-pubescent or -puberulent all around. It has 4 calyx lobes, rounded to acute, 1.8-3.0mm long, equal, mixed eglandular- and glandular-ciliolate, sometimes with longer eglandular hairs as well. The corolla is 4.5-8.0mm diameter. The tube is white, 2.5-6.0mm long, much larger than the calyx, eglandular hairy inside or rarely glabrous. It has 4 lobes, white, erect-patent to spreading, unequal, elliptic to ovate, 2.0-3.5mm long, rounded. The nectar guides are absent. The stamen filaments are white, 3.0-5.5mm long. The anthers are magenta. The style is glabrous, 4.5-9.0mm long.
The capsules are latiseptate, obtuse to sub-acute or slightly emarginate, glabrous, 2.5-4.5mm long, 2.0-3.2mm at widest point. The seeds are ellipsoid to discoid, flattened, smooth, brown, 1.0-1.8mm (rarely to 2.0mm) long.
