Habitat / Range
Introduced; infrequent in sw BC (s Vancouver I., Gulf Is., Lower Fraser Valley). Widespread cosmopolitan weed, native to Eurasia; established widely throughout North America (north to s Canada).

Additional Notes
This species can be a troublesome garden weed in some areas of the south coast. Most populations in B.C. have reddish or salmon-coloured flowers, but plants with dark blue flowers occur occasionally. These blue-flowered plants have been called A. arvensis var. caerulea or A. caerulea in the past, but are not generally afforded taxonomic status by most current authors. The flowers of A. arvensis tend to close on cloudy days.

Family Information
Annual or perennial herbs from fibrous roots, a taproot, a horizontal rhizome, or a small tuber (or a greatly enlarged tuber in Cyclamen); plants often with secretory resin canals that appear as dark dots or streaks. Stems trailing to erect, solitary to several, branched or simple. Leaves generally cauline (all basal in Cyclamen), alternate or opposite (sometimes whorled or pseudowhorled). Inflorescences variable, ranging from solitary axillary flowers or axillary whorls to stalked axillary racemes, terminal or axillary panicles, or erect terminal racemes. Flowers bisexual, usually stalked; corollas usually radially symmetric (sometimes lacking), rotate or campanulate to funneliform, (4-) 5- to 9-lobed; calyces (4-) 5- to 9-lobed; stamens (4-) 5-9; filaments distinct or connate; ovary superior; styles 1. Fruit a capsule, valvate or circumcissile; seeds usually brown or reddish-brown to black. Genera ~50, species ~1400 (5 genera, 12 species in B.C.). Nearly worldwide, except absent from many deserts and polar regions.
The genera here were all formerly included within a broadly-defined Primulaceae, but have since been moved to the closely related Myrsinaceae following recent molecular-genetic studies that have shown strong support for their inclusion in the latter family (Källersjö et al. 2000, Trift et al. 2002, Cholewa et al. 2009). All genera in B.C., with the exception of the genus Cyclamen, are apparently derived from within the large, highly paraphyletic genus Lysimachia (Hao et al. 2004, Anderberg et al. 2007), at least in its broadest sense, and some authors prefer to treat some or all of these genera as members of that genus so as to preserve its monophyly; however, most published phylogenies of the group (e.g., Hao et al. 2004, Manns and Anderberg 2005, Anderberg et al. 2007) suggest that it consists of a number of well-supported individual clades that might be better recognized as genera. Although such an approach would result in the redistribution of some Lysimachia species into new genera, it seems to best represent the systematics of the group and, as a result, it is the approach that is followed in this treatment (i.e., recognition of Steironema, Anagallis, and Trientalis as separate from Lysimachia). Several species of Cyclamen and Lysimachia are grown as ornamentals in southern British Columbia, including the naturalized species Cyclamen hederifolium, Lysimachia punctata, L. nummularia, and L. vulgaris.

Genus Information
Perennial, rhizomatous herbs, sometimes succulent. Stems ascending to erect or sometimes decumbent, simple or branched. Leaves all cauline, opposite or whorled (sometimes becoming alternate above), entire, simple, sessile to petiolate, ovate or oblong to linear-lanceolate. Inflorescences terminal and/or axillary racemes, or flowers axillary (solitary to several per axil); often bracteate. Flowers sessile to pedicellate; corollas usually present (absent in L. maritima), yellow, deeply 5- (9-) lobed, yellow (often with reddish speckling or markings), lobes linear-lanceolate to ovate; calyces green to pinkish or whitish, deeply 5- (9-) lobed, lobes exceeding the tube; stamens 5, included or exserted; filaments distinct or connate at the base. Fruits globose capsules, 5-valvate; seeds 1-20. About 150 spp. (6 spp. in B.C.). Nearly worldwide.
Lysimachia is a large, virtually cosmopolitan genus that reaches its greatest diversity in temperate Eurasia (especially eastern Asia). The circumscription of the genus presented here differs from most recent treatments in that it includes the formerly monotypic genus Glaux [= Lysimachia maritima], which has repeatedly been shown to be an apetalous member of Lysimachia (Anderberg et al. 2007, Cholewa 2009c) and is now generally included within that genus. This treatment of Lysimachia also excludes Steironema ciliatum [= Lysimachia ciliata], as that species is now known to be relatively distantly related to the species here (Hao et al. 2004, Manns and Anderberg 2005, Anderberg et al. 2007); see Steironema for more information. Some species are popular horticultural subjects, including several that have escaped and become established in the province.
