“…The African continent is known for its rich floral biodiversity, high levels of endemism [1] and increasing reliance on its natural resources based on its indigenous knowledge systems, for economic growth and development. The increasing reliance of a growing population coupled with other factors such as habitat destruction, alien species invasion and other anthropogenic factors has resulted in an increasing strain on African plant diversity, creating the need for urgent biodiversity conservation interventions [2]. Globally, there are 119 accepted taxa, including species and infra-species levels within the genus Hypoxis [3].…”

Diversity and Conservation through Cultivation of Hypoxis in Africa—A Case Study of Hypoxis hemerocallidea

Africa has the largest diversity of the genus Hypoxis, accounting for 61% of the current globally accepted taxa within the genus, including some endemic species. Using Hypoxis hemerocallidea as a case study, this review addresses the conservation concerns arising from the unsustainable, wild harvesting of a number of Hypoxis species. Hypoxis hemerocallidea is one of the wild-harvested, economically important, indigenous medicinal plants of southern Africa, with potential in natural product and drug development. There are several products made from the species, including capsules, tinctures, tonics and creams that are available in the market. The use of H. hemerocallidea as a “cure-all” medicine puts an important harvesting pressure on the species. Unsustainable harvesting causes a continuing decline of its populations and it is therefore of high priority for conservation, including a strong case to cultivate the species. Reviewing the current knowledge and gaps on cultivation of H. hemerocallidea, we suggest the creation of a platform for linking all the stakeholders in the industry.

“…Plants were once the primary source of medicines in the world and since then, plants continue to provide humans with new remedies as 50% of all drugs in clinical use in the world are derived from natural products, of which higher plants contribute 25% of the total [5,6]. The use of plants as medicines predates written human history.…”

“…Collection of medicinal plants often cause depletion of their populations and lead to species extinction and biodiversity reduction [14,15]. To avoid local extinction of medicinal plants, one should cultivate target species or conduct harvesting with rules of sustainable use [16,17]. It is possible after investigation of plant life history and population ecology [18][19][20].…”

Population structure, resource potential and diagnostic features of raw materials of Saussurea controversa DC. * The life form and the ontogenesis of the perspective medicinal plant Saussurea controversa DC. (Asteraceae) are described. The species is considered as polycentric, perennial, summer-green, herbaceous polycarpic half-rosette plant with rhizome. The aerial part of the plant includes the polycyclic rosette vegetative and elongated generative shoots. In the ontogenesis, four periods and nine ontogenetic states are distinguished. The ontogenetic and vital structures of four populations were studied in the vicinity of Efremkino village (Republic of Khakassia). Populations are incomplete with accumulation of virginal individuals and predominance of individuals of intermediate and high classes of vitality. Analysis of the distribution and resource research in the population with the highest density and area makes it possible to classify the species as the 3rd category of resource species due the necessity to observe the regime of sustainable use. The diagnostic features of the S. controversa's raw material are the structure of the middle vein of the leaf which includes a large number of vascularfibrous beams and the abaxial epidermis containing stomata of the anomocytous type and 4 types of trichomes. The paper contains 3 Figures and 27 References.
