Aromatic and medicinal plants (MAPs) are not just good business in Morocco, which is ranked 12th globally in export volume and 2nd in diversity. They are also keystone elements of everyday connection between plants and humans in Morocco. Early in my project to understand Moroccans’ communicative ideologies about plant-human relations, I was regularly struck by their descriptions and our intersubjective embodied participation in the touch of smell, the synesthesia of olfactic haptics. The way volatile organic compounds touched, in many senses of the word, nasal smell receptors and created or evoked social interactions; or the ways my Moroccan interlocutors connected smell and the feel of healing heat. In this paper I will explore olfactic haptics as the touch of smell receptors (in a biological idiom) operating in ethnographic fieldwork, and how we might think about touch synthesia and forms of knowing.
