SUBTAXA PRESENT IN BC
Abronia umbellata var. breviflora
Introduction
Pink sand verbena is an annual (sometimes perennial) species of maritime beach habitats, including disturbed sandy areas, coastal scrub, and lees of sand dunes (Spellenberg 2004). It is endemic to the central Pacific Coast of North America where it is found within the driftwood zone. Only one population of the species is known in Canada, from Pacific Rim National Park in British Columbia, although plants have not been seen in several years (Fairbarns et al. 2007). Recovery efforts are underway to reintroduce it within its historical range (Fairbarns et al. 2007). This is a prostrate species with a deep tap-root and trailing stems (Hickman 1993; Spellenberg 2004). Flowering occurs year-round.

expanded illustration for this species.
General: Annual, sometimes perennial herb from a thick, deep taproot, densely glandular-hairy throughout; stems trailing, to 1.5 m long; branches short, forming mats.
Leaves: Opposite, thick and fleshy, lanceolate to narrowly egg-shaped, 2-6 cm long, 0.8-3.5 cm wide; stalks 2.5-7 cm long.
Flowers: Inflorescence of many-flowered, rounded heads on stout flower stalks 2-4 cm long, involucral bracts 5 (4), in a whorl, narrowly lanceolate, 5-6 mm long; perianth tube greenish to pinkish, 6-8 mm long, widely flaring into a pink, 5-lobed limb 5-6 mm wide.
Fruits: Achenes, 10-12 mm long, prominently 3- or 4-winged, the wings of the fruits wider than the fruit bodies.
Notes: This regional endemic was considered extinct in BC and WA until recently (Douglas et al. 1998a, Washington Natural Heritage Program 1994). Two plants of this species were rediscovered in 2000 and subsequently destroyed by a winter storm that year (Douglas 2001). In May 2001 three plants reappeared at the same site.
Coastal sandy beaches below the driftwood zone in the lowland zone; rare on the W coast of Vancouver Island, known only from Ahousat and Pachena Bay (in 1915 and 1927, respectively) and more recently from Clo-oose Beach, Pacific Rim National Park; S to WA.
