Concept Reference: Kartesz, J.T. 1994. A synonymized checklist of the vascular flora of the United States, Canada, and Greenland. 2nd edition. 2 vols. Timber Press, Portland, OR.
Concept Reference Code: B94KAR01HQUS
Name Used in Concept Reference: Anagallis minima
Taxonomic Comments: This species is accepted in the genus Anagallis by Kartesz (1994, 1999) and FNA (vol. 8, 2009). Phylogenetic analysis by Manns and Anderberg (2009) concluded that merging Anagallis, Pelletiera, Trientalis, Glaux, and Asterolinon into Lysimachia is a better alternative and created the combination Lysimachia minima.

General Description: Chaffweed is a low, annual herb with prostrate or erect stems, 2-10 cm long, that root at the nodes. The alternate leaves, 5-10 mm long, are egg to spoon-shaped with entire margins. Foliage is glabrous. Solitary, inconspicuous flowers on short stalks occur in the leaf axils. Each flower has a deeply 4-lobed calyx, 2-3 mm long, and a small, pink, 4-lobed, tubular corolla, ca. 1 mm long, that withers on the maturing ovary. There are 4-5 stamens, and the fruit is a globose capsule that is ca. 2 mm long.
Diagnostic Characteristics: GLAUX MARITIMA is similar but has lower leaves that are opposite each other.
