Revision as of 22:25, 16 December 2019
Staminate inflorescences of solitary, terminal, subglobose glomerules. Fruiting bracteole 3-veined, 2.5–3.5 × 2.4–3.7 mm.
Phenology: Flowering spring–fall.
Habitat: Bluffs, alkaline sinks and drainages
Elevation: 10-500 m
Discussion
L. Abrams and R. S. Ferris (1923–1960, vol. 2) maintained this taxon at the specific level; however, apart from the more apparently veined fruiting bracteoles and reduced staminate inflorescence, var. davidsonii is otherwise identical to var. serenana. It is often found growing with seepweed, samphire, numerous salt-tolerant annuals, other saltbush species.
