The large, doubly dissected leaf of Pelargonium myrrhifolium var. coriandrifolium in picture is young, soft and hairy. Older leaves lose their hairiness, become darker and may develop some glossiness on some parts. Leaf scent, notable when crushed, is said to resemble that of fresh myrrh.
Myrrh is a natural aromatic gum or resin extracted from several Commiphora tree species of the Arabian Peninsula and northeast Africa.
Myrrh resin has been used throughout history as a perfume, incense, and medicine, including the biblical balm of Gilead. Myrrh featured in embalming in the past. It is used in flavouring wine and food.
Coriandrum sativum is an annual herb in the Apiaceae family that grows widespread in western Asia and southern Europe, planted worldwide. All the plant parts are edible, while fresh leaves and dried seeds are most used in cooking (Coates Palgrave, 2002; JSTOR; Wikipedia; http://blog.scentedleaf.com; www.webmd.com).
