“…Pollen morphology, that is so helpful in many other members of the Vernonieae (Bunwong and Chantaranothai 2008; Robinson and Skvarla 2010, Robinson et al 2016), is not useful because pollen of all the genera involved here have the structure that, in the Vernonieae, is called sublophate. This sublophate pollen type has a moderately uneven distribution of spines and muri on the grains with a continuous perforated tectum covering all the non-colpate surfaces and is common in the tribe.…”

Vernonia subgenus Austrovernonia, a new subgenus from South America (Compositae, Vernonieae, Vernoniinae)

Vernoniaincana Less. and V.echioides Less. are two semi-aquatic species from southern South American that are referred to as “the semi-aquatic Vernonia of South America” and they have been, until now, retained as members of Vernonia mostly because each had some unusual characters that made them hard to place. Based on an ongoing molecular study, we can now say that V.incana is the sister taxon to all true Vernonia and can therefore be responsibly left in Vernonia but, because of its morphological and geographic differences, it is now assigned to its own subgenus: Vernonia subg. Austrovernonia. Vernoniaechioides is not closely related to V.incana and is now part of a separate investigation. This placement of V.incana as sister to the true Vernonia species brings up the possibility of a South American root for the Vernonia clade and perhaps indicates a propensity in the lineage for growing in or near water. The species V.incana is lectotypified.

“…However, the question of where to place these two somewhat odd South American species continued to puzzle students of the tribe. The situation remained unchanged as attention turned to the greater problems found in the Old World Vernonieae (Robinson 1999a, Robinson et al 2016, Bunwong et al 2014, Funk and Robinson 2017). …”

Centrapalus pauciflorus is a herbaceous plant that is used as a traditional medicine and a source of epoxidised oil. This study is aimed at providing a critical review of the pharmacological properties, phytochemistry and medicinal uses of C. pauciflorus. Documented information on the pharmacological properties, phytochemistry and medicinal uses of C. pauciflorus was collected from several online sources, which included Scopus, Google Scholar, PubMed and Science Direct, and pre-electronic sources such as scientific publications, these, books, dissertations, book chapters and journal articles. This study showed that the leaves and epoxidised oil of C. pauciflorus are used as traditional medicines for external injury, wounds, diabetes, chest pains, eye infections, stomach problems and skin infections. Phytochemical compounds identified from the species include coumarins, essential oils, fatty acids, flavonol glycosides, phenolic acids, sterols, sesquiterpene lactones, triterpenoids, alkaloids, cardiac glycosides, carotenoids, flavonoids, polyuronoids, saponins, steroids, tannins and terpenoids. Pharmacological research revealed that C. pauciflorus extracts and compounds isolated from the species have analgesic, anti-dermatitis, antimicrobial, antiulcerogenic, hypoglycemic, insecticide, larvicidal and sedative activities. Centrapalus pauciflorus should be subjected to detailed phytochemical, pharmacological and toxicological evaluations aimed at correlating its medicinal uses with its phytochemistry and pharmacological activities.

Baccharoides adoensis is a shrub widely used as traditional medicine throughout its distributional range in tropical Africa. This study is aimed at providing a critical review of the pharmacological properties, phytochemistry, and medicinal uses of B. adoensis. Documented information on the pharmacological properties, phytochemistry, and medicinal uses of B. adoensis was collected from several online sources which included Scopus, Google Scholar, PubMed and Science Direct. Additional information on the pharmacological properties, phytochemistry, and medicinal uses of B. adoensis was gathered from pre-electronic sources such as book chapters, books, journal articles, and scientific publications sourced from the university library. The articles published between 1962 and 2020 were used in this study. This study showed that the roots, flowers, stems, and leaves of B adoensis are widely used as ethnoveterinary medicine and traditional medicines for backbone pain, reproductive problems, kidney diseases, fever and febrile complaints, wounds, ulcers, sexually transmitted infections, skin complaints, malaria, gastro-intestinal problems and respiratory problems. Phytochemical compounds identified from the species include alkaloids, carbohydrates, chondrillasterol, flavonoids, free sugars, glaucolides, glycosides, phenols, proanthocyanidin, saponins, steroids, tannins and terpenoids. Pharmacological research revealed that B. adoensis extracts and compounds isolated from the species have antimicrobial, antimycobacterial, anti-inflammatory, antioxidant, antiplasmodial, anti-pyretic, antitrypanosomal, antileishmanial, anti-ulcer and gastroprotective, immunomodulating, inhibition of Helicobacter pylori adhesion, larvicidal, cytotoxicity and toxicity activities. Baccharoides adoensis should be subjected to detailed phytochemical, pharmacological, and toxicological evaluations aimed at correlating its medicinal uses with its phytochemistry and pharmacological activities.
