Brittlebush (Encelia farinosa) is another desert spectacular that grows on rocky hills and sandy arroyos. If you look closely at the leaves you will see tiny insulating white hairs, known as pubescens. If you look closer still you may even see a difference between the degree of pubescens from brittlebush that grow on the rocky hills and those that live in the sandy washes. The ones in the sandy washes have a lesser degree of pubescens. Why do you think this is so?
