relationships between people and plants
Ethnobotonists study the relationships that exist between people and plants.
I think that would be human geography?
The best way to explain an Ethnobotanist's studies is to break down what the word actually means. Ethno being the study of ethics, and botan, (or botany) as the study of plants, so the best description for an ethnobotanist would be someone who studies the ethicical uses of plants in different cultures across the world. some examples would be an anthropologist who studies different societies that use Ayauaska for spiritual experiences.
'This question has no bearing on his qualifications and expertise as an ethnobotanist.' That wasn't the question.
