Key to families | Table of families and genera This text currently parallels The Jepson Manual: Vascular Plants of California, Second Edition that is now available at the University of California Press. Text appearing in blue on this page will not appear in the printed book; it will be displayed only on the Web. Specimen numbers are hyperlinked to records in the Consortium of California Herbaria data view where possible. Taxa are hyperlinked to entries in the Jepson Interchange via the "[Online Interchange]" link. |
Plant ± erect to spreading.
Stem: simple to diffusely branched.
Leaf: cauline, alternate, opposite or whorled, ± sessile, generally entire.
Inflorescence: flowers 1 in axils of upper leaves, generally pedicelled.
Flower: calyx persistent; filaments free or fused at base.
Fruit: circumscissile, spheric.
20 species: generally Eurasia. (Greek: pimpernel) [Manns & Anderberg 2005 Int J Plant Sci 166:1019–1028] Inclusion of Anagallis minima, Centunculus minimus in TJM (1993), controversial, based primarily on morphology; reports of Anagallis foemina from CA based on blue-flowered forms of Anagallis arvensis.
Unabridged note: Placement of Anagallis minima (Centunculus minimus) is problematic. Martins et al. (2003) have nuclear DNA evidence to indicate Centunculus is closely allied to the Lysimachia clade and not Anagallis, but the morphology coincides more with Anagallis (see Kubitzki, K. et al., eds. 2004. Fam Generally Vasc Plant, 6+ vols. Berlin, Springer) and placement has gone back and forth with inclusion being the current concept.
1. Perennial; calyx 4–6 mm ..... [A. monelli]
1' Annual; calyx < 5 mm
2. Calyx <= corolla; flower distinctly pedicelled ..... A. arvensis
2' Calyx > corolla; flower sessile or nearly so ..... A. minima
