Genus: AbroniaView DescriptionDichotomous Key

Habit: Annual, perennial herb, generally glandular. Stem: prostrate to ascending, generally +- red. Leaf: generally fleshy, petioled. Inflorescence: head or umbel; flowers maturing outer before inner or +- simultaneously; receptacle conic, +- smooth; bracts 5--10. Flower: perianth salverform to trumpet-shaped, generally fragrant, lobes 4--5; stamens 4--5, included; stigma linear, included.

Species In Genus: 25 species: western North America. Etymology: (Greek: graceful) Note: Closely related to Tripterocalyx; relationships among species Abronia gracilis Benth. (Mexico), Abronia maritima, Abronia umbellata, and Abronia villosa need study; hybrids involve Abronia latifolia, Abronia maritima, Abronia umbellata; Abronia gracilis included in TJM (1993) based on misidentifications.
