At least 511 medicinal plant species are traded commercially in 50 Witwatersrand  umuthi shops. The plants are listedalphabetically by genus and common (vernacular) name. The orthographic vernacular names, as well as the orthographicvariations in these names, are incorporated into the list. Annotations include the plant family, the number of umuthi shopsstocking the species, the language of the common name, and the plant part traded. The plant family in the region which hasthe highest number of species and infraspecific taxa in trade is Liliaceae  sensu lato., followed in descending order by  Fabaceae, Asteraceae. Euphorbiaceae and Amaryllidaceae. Approximately 88.6% of the vernacular names are in Zulu. Themean number of umuthi shops per species is 12.3. ranging from 1 to 41. Three hundred and fifty three species (69.2%) occurin the four northern provinces, and 23 species are listed as threatened on the Red Data List.

Trading of herbal medicines generates economic opportunities for vulnerable groups living in periurban, rural, and marginalized areas. This study was aimed at identifying medicinal plant species traded in the Limpopo province in South Africa, including traded plant parts, conservation statutes of the species, and harvesting methods used to collect the species. Semistructured questionnaire supplemented by field observation was used to collect data from owners of 35 informal herbal medicine markets in the Limpopo province. A total of 150 medicinal plant products representing at least 79 plant species belonging to 45 botanical families, mainly the Fabaceae (11.4%), Asteraceae (7.6%), and Hyacinthaceae (6.3%), were traded in the study area. Roots (50.0%), bulbs (19.0%), and bark (16.0%) were the most frequently sold plant parts. Some of the traded species which includeAlepidea amatymbica, Bowiea volubilis, Brackenridgea zanguebarica, Clivia caulescens,Dioscorea sylvatica,Elaeodendron transvaalense, Encephalartos woodii,Eucomis pallidiflorasubsp.pole-evansii,Merwilla plumbea,Mondia whitei,Prunus africana, Siphonochilus aethiopicus, Synaptolepis oliveriana,andWarburgia salutarisare of conservation concern and listed on the South African Red Data List.Findings of this study call for effective law enforcement to curb illegal removal of wild plants especially those species that are at the verge of extinction.

"Quina" (Strychnos pseudoquina A. St. Hil) is a medicinal plant species from the Brazilian Cerrado. As its seeds show dormancy, they were subjected to the treatments pre-cooling at 5ºC during 7 days, pre-heating at 40ºC during 7 days, pre-soaking in sulfuric acid PA during 5 and 15 min, pre-soaking in boiling water during 5 and 15 min, pre-soaking in 100 and 200 ppm gibberellic acid during 48 h, pre-soaking in distilled water during 24 and 48 h, and mechanical scarification to break dormancy. Counts were daily conducted from the 2nd day after the experiment implementation until the germination stabilization at the 65th day. The germination speed index (GSI) and the germination percentage were evaluated. Germination rates above 96% were reached in seeds pre-soaked in water during 48 h and substrate moistened with water or KNO3.
