abstract = {The pollinarium morphologies of 85 species and four subspecies of Hoya were investigated in the present study. The longest pollinium was found in Hoya multiflora, the widest in H. archboldiana, and the smallest in H. bilobata. Pollinium shape showed the widest variation range of all palynological characters, and nine shapes were distinguished in this study. A pellucid margin was present in the pollinium of 84 taxa, and absent in five species. In total, 10 types of pollinarium were recognized based on the following characters: presence/absence of a pellucid margin and the caudicle wing, the ratio of corpusculum/pollinarium length, width/length of pollinium, and curving orientation of the caudicle wings. Types V and X were found in a greater number of taxa compared with the other eight types. Type V is a combination of obliquely elongate or oblong pollinium, presence of a pellucid margin and caudicle wing, and corpusculum length less than half of the pollinium. Type X combines pollinium with variable shapes, a pellucid margin, unwinged and twisted caudicle, and corpusculum with obvious lateral extensions. The characters of 46 taxa with a resolved position in the latest phylogeny of Hoya were mapped and ancestral reconstruction analysis was carried out, indicating that the presence of a pellucid margin in the pollinium, corpusculum length less than half of the pollinium, and rhomboid-shaped corpusculum with lower extensions represent the ancestral state of the genus. Clade II is characterized by the absence of a pellucid margin and twisted caudicles.

The stapeliads, shown convincingly to be nested within Ceropegia, are primarily characterized by their non-climbing, highly succulent, tuberculate stems with fleshy flowers with a mostly short corolla-tube. However, highly succulent, tuberculate stems are not restricted to the stapeliads and are present in four lineages of Ceropegia. Furthermore, tubular flowers are also found among the stapeliads and are not restricted to Ceropegia. Since a slender, tubular corolla is extremely homoplasious within Brachystelma, Ceropegia and the stapeliads, we move away from this as defining Ceropegia to recognize some sections in which there is a range from slender, tubular flowers to almost flat flowers. To re-establish a monophyletic Ceropegia, we propose a new classification in which Brachystelma and all genera of the stapeliads are placed in a greatly enlarged Ceropegia. This new concept of Ceropegia is defined by the lack of hard, wiry roots, the softly fleshy tissue of the peduncles and pedicels, the absence of any corolline corona, the presence of two well-developed series of the staminal corona and the presence of a compitum in the style-head leading to the fertilization of both ovaries. We transfer the species of Brachystelma into several sections of Ceropegia and reduce the 31 stapeliad genera to sections of Ceropegia, after which Ceropegia has 63 sections. Sect. Chamaesiphon H.Huber is the largest with 115 species, two sections among the stapeliads each contain over 50 species but the remaining sections are mostly considerably smaller.

abstract = {Aims of the study
Several species of the stapeliads, a group of stem succulents belonging to the family Apocynaceae are reported on in the ethnopharmacology literature and many of the references relate to their use as food plants. The most important of these plants is Hoodia gordonii, which during the past decade has risen from an almost forgotten spiny, desert plant to an important commercial appetite-suppressant herbal. The aim of this review is to summarize the botany, ethnopharmacology and phytochemistry of Hoodia gordonii.
Materials and methods
Journal articles and books were used to collect information on Hoodia gordonii and related species.
Results
Many books and articles documented the use of stapeliad species as food plants and earlier references refer to the use Hoodia species as a thirst quencher. However, prior to the publication of the patent application, only a single reference referring to the use of Hoodia pilifera as appetite suppressant was found. The structures of several steroid glycosides isolated from Hoodia gordonii are summarized.
Conclusions
Hoodia gordonii illustrates how a combination of ethnobotany and scientific research can lead to a commercial product which can greatly benefit the indigenous people.},
