Duration: Perennial Nativity: Native Lifeform: Subshrub General: Ephemeral to short lived perennial 20-80 cm tall with ashy-strigose, glandular glandular branches, the stipules 1-2 mm long. Leaves: Pinnate 3.5-6 cm long with 15-35 leaflets, these suborbicular to obovate, emarginate and strigose and glandular on both sides, 2-6 mm long. Flowers: On racemes 2-10 cm long with many flowers, the calyx strigose with a top-shaped tube, 1.5-2 mm long, the calyx lobes deltoid with upper four lobes half as long as the tube, the corolla violet to purple, the banner reniform, 1.5 mm long, 2-2.5 mm wide, with a 1 mm long claw, the blades of wing petals 3 mm long, paler to nearly white along the lower margin. Fruits: Pods puberulent between rows of glands, 2-2.5 mm long. Ecology: Found on rocky slopes and in washes below 4,000 ft (1219 m), flowers March-June. Distribution: Across the Sonoran and Mojave deserts south into southern Sonoran and Baja California. Notes: Distinguished by the racemose flowers, with stout stems, but an ephemeral species at that. Flowers are white and purple, stems are somewhat suffretescent, and the herbage and calyces are strigose-canescent. Look also at the seed pods which are furry, with rows of long hairs alternating with rows of glands. Ethnobotany: Unknown Etymology: Marina refers to marine, or of the sea, while parryi is named for Dr. Charles Christopher Parry (1823-1890), an English-born American botanist and collector.
