Mutamba is a thirteenth-century settlement located on the Soutpansberg Mountains in northern South Africa with links to the regionally important Mapungubwe polity. This paper provides a detailed report of the range and utilisation of archaeobotanical taxa found at Mutamba. This research provides base-line evidence on the little understood, but significant role of plants in southern African Iron Age society. The analysis of 100 randomly selected samples from domestic features yielded 11 identifiable species and two genera. The results provide evidence for a potential crop package made up of finger millet (Eleusine coracana), sorghum (Sorghum bicolor), pearl millet (Pennisetum glaucum), cowpeas (Vigna unguiculata) and mung beans (Vigna radiata). Mutamba also contains the first documented example of Vigna radiata as a crop component in South Africa, the first tangible indication for the occurrence of malted grains used in beer brewing and the first archaeological links between Gossypium herbaceum and cotton spinning, previously based only on ethnographic data.

Archaeological excavations in Florence (Italy) offered the opportunity of collecting archaeobotanical data along stratigraphic sequences and pits from late Roman to Middle Ages; until now, no archaeobotanical data of this range of time were available for Florence. To achieve a more comprehensive reconstruction of the antique landscape and of the plant uses in the city, the results of plant micro- and macro-remain analyses were compared. During the late Roman Period, mixed oak forests covered the surrounding hills, while only scattered riverine thickets grew in the Arno river plain, which was mostly open. In the city, the increase in richness of cultivated plants, weeds and ruderals follows the advancement of urbanization from the late Roman to the Middle Ages when the abundance of remains of cereals, figs, grapevines and other fruits showed that cultivation and/or food processing were performed close to and even within the town wall. Peaks of heather (Ericaspp.) pollen suggested that its flowering branches were introduced in the site and possibly used as building material or for the maintenance of the Arno river bank. Thus, this integrated archaeobotanical approach provided new insights into the environmental and ethnobotanical history of Florence, highlighting the occurrence of horticulture within the city wall.

This article is based on a study that was carried out in Nhema communal area in Midlands Province, Zimbabwe, with the main objective of documenting local plant use and traditional conservation practices. Data collected through household semi-structured and open interviews showed that 46 plant species in 40 genera and 24 families were mainly used for firewood, construction wood, food and traditional medicine. Other minor uses included using plant species for making mats, rope and shading. Firewood and construction wood ranked as the most important tree products used. The preferred plant species included: Julbernardia globiflora (Mutondo); Brachystegia spiciformis (Musasa); Terminalia sericea (Mususu); Brachystegia boehmii (Mupfuti); Combretum imberbe (Mutsviri); Combretum molle (Mubondo) and Burkea africana (Mukarati). Some of the highly preferred species, considered to be declining in the local environment, included Adenium obesum (Chisvosve); Azanza garckeana (Mutohwe); Brachystegia boehmii (Mupfuti); Brachystegia spiciformis (Musasa); Burkea africana (Mukarati); Combretum imberbe (Mutsviri); Combretum molle (Mubondo); Dalbergia melanoxylon (Mukonashanhu); Diospyros mespiliformis (Musuma); Elephantorrhiza goetzei (Ntorani); Julbernardia globiflora (Mutondo); Phragmites australis (Shanga; Poulzozia hypoleuca (Munanzwa); Pterocarpus angolensis (Mubvamaropa); Terminalia sericea (Mususu) and Uapaca kirkiana (Muzhanje). Highly preferred and declining species were characteristically large trees and shrubs. Local people are aware of the need to conserve plant resources in order to protect the environment and avoid the extinction of these rare species.Traditional conservation practices have substantially contributed to the conservation of plant species in Nhema communal area. The protection of indigenous timber, fruit trees, trees with social and cultural significance, the use of deadwood for firewood, the use of eucalyptus trees as construction wood and the occurrence of sacred woodland areas represented some of the traditional conservation techniques employed in Nhema communal area. These local practices demonstrate the dynamism and significance of African indigenous knowledge systems. [ABSTRACT FROM AUTHOR]

Cannabis is grown and processed for a wide variety of uses. Many plant parts are used as medicine for humans and livestock; whole seeds and seed oil are eaten by humans; seeds and leaves are fed to animals, seed oil and stalks are burned for fuel. Whole plants, leaves and wood have environmental uses and bark, fiber and seeds are also of ritual importance. This paper introduces an interview schedule and questionnaire for investigating Cannabis use. [ABSTRACT FROM PUBLISHER]
