Erodium dimorphum Wendelbo
Erodium dimorphum is perennial, dioecious; with stems tufted; plant covered in persistent stipules & leaf bases; root rhizomatous.
Leaves: Leaves silvery green, dissected, hairy, leathery; intercalary leaflets – only 1 or 2 lobules below one of the pinnae of the second pair!
Inflorescence: male plants with long-peduncled many-bracted umbels of 5-6 flowers with small sepals 4-5mm; the female plants either reduced to a 1-flowered umbel with 2 bracts on a peduncle up to 40mm , or the bracts absent so the flowers appear single axillary basal, with sepals 7mm long; petals white, upper two barely marked rounded broad; sepals hairy on the outside only, not to small mucronate, ovate, acute.
Distribution: endemic to Iran; Eastern Elburz mountains, crevices of cliffs of the Nezva Kuh at 3300m.
Notes: El-Oqlah says very like E. salmonium in leaf shape and dissection, but differs in hairiness and in the stem and peduncles morphology
