Show moreThis thesis describes Saramaccan Maroon medicinal plant knowledge, practices and beliefs in relation to local health care, education and biocultural conservation. The Saramaccan ethno-medical system in the village Pikin Slee focused primarily on cure followed by health promotion, and disease prevention. People made a deliberated choice for traditional medicines, even though most health concerns could be treated in the village health center. Herbal bathing plays a significant role in providing local health care among Maroons. The geographical separation between the Saramaccan and Ndyuka Maroons have led to distinct plant use in their herbal bathing practices.Writing proper Saramaccan plant names and the translation of health issues from Saramaccan into Dutch is a challenge for pupils in Pikin Slee, indicating a gap between the official school curriculum (in Dutch), traditional knowledge and literacy in Saramaccan. The growing influence of Sranantongo interrupts the conservation of Saramaccan traditional ecological and cultural knowledge stored in plant names which are influenced by European, African and Indigenous languages. Central-African Bantu languages, especially Kikongo, contributed most to the names followed by West-African Kwa languages. As Saramaccan plant names store large amounts of traditional knowledge, they play an important role in the conservation of Saramaccan biocultural heritage. Show less

Show moreWe described a total of 4 species and 4 subspecies of Coelogyne and one species of Panisea from the Himalayan region as new species to science based on analysis of morphological characters and DNA sequences. Extrafloral nectar produced by Nepalese Coelogyninae was found to play a key role in attracting aggressive ants protecting flowers and leaves against herbivorous beetles. This nectar was found to be exudated by nectary-modified stomata positioned just below the pedicels on the inflorescence. Our ethnobotanical survey showed that a total of 60 species of wild orchids were found to be used as energizers, aphrodisiacs and treatments of burnt skin, fractured or dislocated bones, headaches, fever and wounds. The antibacterial screening carried out by us indicated that the majority of the medicinal orchid species used by local people in Nepal showed biological activity. A total of 10% of confiscated orchids remained sterile but could be identified to species level by applying DNA barcoding and chemical profiling. Our market surveys in central Nepal showed that many wild orchid species are involved in illegal trade and exported to China and India for preparation of herbal products and traditional Chinese medicines. Wild orchids were found to be immensely important to sustain local livelihoods in Nepal. Due to large scale ille_gal trade, many species are rapidly becoming endangered in the wild. Establishing sustainable orchid breeding enterprises could be a valuable alternative for the production of medicinal orchids for local communities. Critically endangered species should be placed on CITES Appendix I to prevent their extinc_tion from the wild. DNA barcoding and chemical profiling seem promising tools for a better control of cross-border illegal trade. Show less
