Ethnobotanical studies often assume plant knowledge is shared by all members of an arbitrarily bounded human group. By describing the uses and local categorization of plants in one village in rural Panama in a heteroglossic approach, the different knowledges within a village are presented in one article. Plants used in the daily work of women and men, and the work of village specialists are described. Villagers negotiate changing realities by adapting plant use and knowledge; this is reflected in local categorization of plant names into antes and hoy día. Unlike the established ethnobotanical assumption that bounded units of plant knowledge are dying, the younger generations of villagers, who work both within and outside the village, know more plants useful to their changing economic opportunities. Subsistence agriculturalists possess the adaptive plant knowledge skills to be stewards of the environment.

Twenty breadfruit cultivars growing in a field genebank at Kahanu Garden, National Tropical Botanical Garden, Hana, Maui, Hawaii, were evaluated for sensory attributes and nutrient composition. A taste panel scored eight flavor/aroma attributes, five textural attributes, and color. There were significant differences (P ≤0.01) in aroma, visual texture, flavor intensity, sweetness, starchiness, moistness, stringiness, firmness, and color. The greatest differences were in color and texture. Nutrient analyses showed significant differences (P ≤0.05) for energy, carbohydrates, ash, crude protein, potassium, magnesium, sodium, iron, copper, and zinc. Considering the versatility of breadfruit as a food, its ease of production, and its nutritional value, the numerous good quality flavorful cultivars available should be more widely grown for sustainable agriculture and food security.

This is the first time aspects of the ethnobotany of East Timor have been reported. The medicinal plant traditions of two distinct East Timorese cultures, the Laklei and Idate, were studied and compared using quantitative ethnobotanical methods. A total of 86 medicinal plant species were identified. The medicinal plant traditions of the Laklei and Idate cultures were compared using Trotter and Logan's (1986) quantitative “informant agreement ratio.” On average, informant consensus was greater in Laklei, suggesting a medicinal plant tradition that is more defined than in Idate, where informants are more likely to use the same medicinal plants when treating the same usage categories. Furthermore, only 11 of the 86 medicinal plant species documented were used by both cultures, of which only six had similar mentions. These findings have important implications for the understanding of ethnobotany as they demonstrate how relatively closely situated cultural groups can have significantly different traditional knowledge systems.

The indigenous people of Australia have a long and well-documented history of using native plants as an essential component of their customary economy. However, few have engaged successfully in commerce based on native plant use. Recently there has been an increasing interest in exploring options for use of native plants for food, food additives, botanical medicines, and related purposes. In this paper, we determine the issues important to Aboriginal people in enterprise development utilizing plant products, and we define some of the factors affecting progress in realizing opportunities. The Aboriginal people with whom we have worked appear to prefer small-scale enterprises where they have community ownership of ideas and control of the rate and direction of development. Government could play a larger and more active role through supporting additional research and marketing information, providing training, and better matching policy and legislation to support indigenous development and reduce dependence of welfare.

In the present study we analyzed medicinal and edible plant utilization in Cuyin Manzano, a small rural population located near the Andean forests of Argentina. We also studied where and when plant knowledge was learned, who the principal transmitters were, and how people were taught. The participants were interviewed individually and at random, by means of a semi-structured questionnaire. Interviews were carried out in 16 families in order to examine the present use of wild plants. The inhabitants of Cuyin Manzano cited 87 plants: 63 medicinal and 24 edible species. They mentioned on average 31 ± 10 species per person. Similar patterns of plant use were found in young and old people alike, irrespective of gender. Learning about useful plants took place at an early age as a result of family tradition. This local knowledge is acquired and taught “by doing,” and is mostly transmitted vertically through family dissemination. Wild plant learning implies the acquisition of plants' physical and functional features as well as their environmental characteristics.
