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.
