Cauline leaves mostly in 5–8 pairs, blade ± ascending throughout, 0.8–1.2 mm wide. Inflorescences: branches erect to ascending. Flowers: sepals 4.5–7.2 mm, to 8 mm in fruit, ± glabrous; nectaries thickened, molarlike, apically 2-lobed, 1–1.5 mm.
Phenology: Flowering spring–summer.
Habitat: Open woodlands, sagebrush flats, dry, rocky slopes, alluvial deposits, often on carbonates
Elevation: 600-2200 m
Distribution
Ariz., Calif., Nev., Utah.
Discussion
Plants with petals equaling or barely exceeding the sepals and with cauline leaves fewer than five pairs have been recognized as Arenaria macradenia var. parishiorum; those features intergrade completely with var. macradenia. See M. F. Baad (1969) for his reasons for accepting var. parishiorum as a species.
B. Maguire (1947) included “Lower California” in his distribution statement for var. macradenia, implying Baja California; we have not seen any collections from that area.
Selected References
None.
