A new species of Ceropegia (Apocynaceae: Asclepiadoideae-Ceropegieae-Stapeliinae) is described from Ngome in KwaZulu-Natal, South Africa. This new species shares a subset of vegetative and floral characters with the long-lost C. rudatisii, but is clearly separated by its sophisticated floral morphology. Ceropegia heidukiae occurs in Northern Zululand Mistbelt Grassland, an endangered vegetation type. A comprehensive species description is provided together with information on habitat and distribution; photographs of plants in habitat are also provided. A preliminary assessment of conservation status according to IUCN criteria suggests that C. heidukiae is Critically Endangered (CR).

Micronutrient consumption in many developing countries is insufficient to meet the needs of numerous individuals, resulting in a negative impact on health. Increasing consumption of wild edible plants, which are micronutrient rich, easy to grow, and culturally familiar, has been recommended to combat these deficiencies, but there is a gap in knowledge on which types of plants should be eaten or in what quantity. The objective of this project was to determine the optimal blend of South African wild edible plants needed to fill gaps between typical micronutrient consumption of lactating women in KwaZulu-Natal, South Africa, and estimated requirements. This was done by creating optimization models using linear programming. Components of these models included identifying gaps between current micronutrient intake measured in a sample of lactating women and Estimated Average Requirements (EAR) and the creation of composite nutrient profiles for groups of wild edible plants available in KwaZulu-Natal. Models calculated the optimum amounts of wild edible plants that would need to be consumed in addition to the current diet to meet micronutrient recommendations and the amounts needed if half the additional calories consumed would replace an equivalent number of calories of maize meal. A combination of 250g leafy vegetables and 349g fruit, replacing 54g of maize meal, was determined to be the best model. This mixture met the micronutrient needs of 50% of lactating women and added only 192 calories to the diet. This data can provide policy makers with the information necessary to formulate effective nutritional interventions. The high level of recommended change, however, also highlights the need to employ multiple approaches to achieving improved nutrition. Additional information is needed on the availability and nutritional values of wild edible plants in South Africa. Despite these limitations, it is clear that a reasonable increase in wild edible plant consumption can have a tremendous positive impact on micronutrient consumption of lactating women in KwaZulu-Natal, South Africa.

Abstract. Mncwango NC, Mavengahama S, Ntuli NR, van Jaarsveld CM. 2020. Diversity, consumption dynamics and ethnomedical claims of traditional leafy vegetables consumed by a rural community in the KwaMbonambi area, northern KwaZulu-Natal, South Africa. Biodiversitas 21: 1196-1202. Traditional leafy vegetables  (TLVs) are mostly wild and informally-domesticated edible plant species. Their nutritious leaves, shoot tips, flowers and fruits are consumed as vegetables, particularly by rural communities in Africa. However, their consumption and cultivation are still marginal. This study aimed to identify the most preferred TLVs, as well as factors that affect the consumption and cultivation of these species. A questionnaire was administered among 100 respondents to record the preferred TLVs; the reason (s) for preference; consumption frequency; and constraints towards consumption of these vegetable species. This study recorded a total of 18 TLVs that belong to 14 genera and 11 families. Among these, Amaranthus hybridus, A. spinosus, A. thunbergii, Bidens biternata and Corchorus olitorius were the most preferred species. Vegetables were preferred primarily based on the taste; where most people ate them once a week when they are available. The major TLV consumption constraints were seasonal availability and low shelf life. A decline in the availability of TLVs was primarily caused by drought. Regardless of the observed decline, only 23% of respondents practiced informal cultivation of Amaranthus species. Bidens pilosa, Momordica balsamina, and Corchorus olitorius vegetable species were also known to possess some medicinal values. Future research on improving taste, increasing edible plant parts and elongating shelf life for preferred TLVs, is a necessity.
