An ethnobotanical field study focusing on traditional wild food botanical taxa was carried out in Kaniguram, South Waziristan, Pakistan, among Ormur (or Burki or Baraki) peoples, which represent a diasporic minority group, as well as among the surrounding Pashtuns. Through sixty semi-structured interviews, fifty-two wild food plants (taxa) were recorded, and they were primarily used raw as snacks and cooked as vegetables. Comparative analysis found a remarkable overlap of the quoted plant uses between the two studied groups, which may reflect complex socio-cultural adaptations Ormur speakers faced. Ormur people retain a rich knowledge of anthropogenic weeds and the phytonyms reveal important commonalities with Persian and Kurdish phytonyms, which may indicate their possible horticultural-driven human ecological origin from the Middle East. Some novel or rare food uses of Cirsiumarvense, Nannorrhops ritchiana, Periploca aphylla, Perovskia atriplicifolia, Viscum album,Oxalis corniculata and Withania coagulans were documented. Since the Ormuri language represents a moribund language, still spoken by only a few thousand speakers in NW Pakistan and Afghanistan, it is recommended that the traditional bio-cultural and gastronomical heritage of this minority group be appropriately protected and bolstered in future rural development programs.

Background: The local wild edible plants (WEPs) are still used traditionally in the rural communities in Yemen, but this traditional knowledge is still undocumented and has been never reported before. Therefore, this study is the first ethnobotanical survey on WEPs conducted in Yemen. Methods: The study is based on two field surveys made in two periods 1988–1992 and 2014–2016 to document the wild plants used as edible by local indigenous peoples in 23 districts belonged to five governorates, in southern Yemen. Information data were collected by oral face-to-face interviews from 250 informants. Citations numbers were calculated for each species. Results: A total of 58 plant species belonged to 37 genera and 21 families are reported as wild edible plants consumed in southern Yemen. Apocynaceae was the dominant plant family with 18 species followed by Asteraceae (6) and Malvaceae (5). The most widely used edible parts are stem, leaf and fruit with more than 17 species for each. Herbs were reported as the most important sources (31 species), followed by shrubs (16) and trees (9). Most of reported wild edibles (48 species parts) are consumed in raw form; only 12 of them are cooked. Seven wild edible plants were collected in dry season, 16 species throughout the year and 38 in rainy season. In this study, 58 wild plants were reported for the first time as food in Yemen. Comparing the southern Yemeni findings to those from other world countries, 12 of them are new WEPs eaten only in southern Yemen, while 46 species are shared in the use in different world countries practically in East Africa and Arab countries. Conclusions: The results data reflect the strong relationship between the local peoples and the local WEPs as potential sources insure food security. The traditional use of these WEPs is attributed to food shortage, nutritional values and local cultural tradition. The study is of great importance in preserving the traditional and knowledge heritage from being lost due to the risks of time, war and immigration.
