Habit: Perennial herb or subshrub, from rhizome, stolon, or caudex, glabrous or glandular-hairy. Leaf: blade entire or toothed. Flower: erect to spreading or nodding; generally homostylous; sepals erect or reflexed in flower, erect in fruit, persistent; corolla salverform or funnel-shaped with well-developed tube, including anthers, and erect to spreading, notched lobes, or rotate with very short tube, prominently exerted anthers, and reflexed, entire lobes, proximally white and/or yellow and/or dark purple, distally white, lavender, pink, or purple; filaments generally very short, including anthers free, oblong, exerted anthers on generally wide, often fused filaments, erect, generally +- lanceolate, generally +- adherent into a cone around style; ovary superior, style slender, +- exserted beyond anthers, stigma head- or dot-like. Fruit: +- 5-valved or circumscissile, ovoid or oblong-ovoid to cylindric.
Species In Genus: +- 470 species: generally northern temperate. Etymology: (Latin: diminutive of first, from early flower) Note: Dodecatheon, a monophyletic taxon closest to Primula subg. Auriculastrum, recently treated in that subg. as sect. Dodecatheon (Mast & Reveal 2007); taxa treated in Dodecatheon in TJM2 treated in Primula here. Polyploid group; species often intergrade; "anther connective" refers to tissue between pollen sacs, especially near base; dehiscence must be determined on fruit that has aged and dried naturally, because e.g., green fruit of circumscissile taxa (e.g., Primula clevelandii) sometimes split longitudinally as a result of pressing and thereby may appear valved.
