The topic of this article can be described as memory-based studies of plant diversity or botanically-focused oral histories; and the method is ethnographic. Attending to the everyday practices constituting botanical memory, the article posits a material-affective framework to foreground the dynamics between plants, people, objects, and remembrance. The writings of Henry David Thoreau and C. Nadia Seremetakis, in conjunction with affect and materiality theory, offer conceptual anchor points for this exploration of human recollection and flora. The interviews indicate that plant-based objects and living plants deepen human memory, particularly through their appeal to touch, taste, smell, and sensation.展开更多

In the context of enslavement and the cultural dislocation that accompanied it, memory became critical in the recreation of tradition. Individual memory contributed to the practices that created new traditions to be carried forward by subsequent generations. Archaeological evidence from Clifton Plantation, Bahamas, illustrates how memory and tradition shaped the identities of both enslaver and enslaved, and influenced the construction of an African Bahamian identity in the early nineteenth-century. In their consumer selections, the enslaved people of Clifton were constructing artifact assemblages that reflected their memories of their traditional cultural background. In the process they were creating an Afro-Bahamian aesthetic that would become a tradition for future generations of Bahamians. While the goods were not of their own manufacture, the choices were theirs from the selection available to them. At the same time, those of British heritage were signaling their British identity through their consumer choices. However, Clifton was unusual in being owned by a reformer who sought to ameliorate the conditions of slavery. The paper also briefly discusses whether these concepts are useful in understanding the material culture of enslaved Africans at other sites.展开更多
