“…In these regions can be noted botanists working on orchids. For instance, Reiter et al (2013) and Indsto et al (2006) in Australia, there are two scientific teams in Africa, including Bulafu et al (2007), Mucunguzi (2007) in the first team, and Descourvières et al (2013), Droissart et al (2014), Ječmenica et al (2016, 2017, Simo-Droissart et al (2018) in the second one.

A systematic global literature review of studies devoted to Orchidaceae taxa in Protected Areas is presented here. It is aimed to understand research topics of studies on orchids in Protected Areas around the world. Used is the methodology well established in biological and medical science with a focus on two international databases (Scopus, Web of Science Core Collection) and one national (Russian Science Citation Index). Examined are the data on each paper's Protected Area location, habitat studied, topic discussed, and IUCN status of each Protected Area. It is hypothesised that orchids are predominantly investigated in Protected Areas, and therefore, the published results of studies on orchids are properly indexed by databases globally. The question is whether the most threatened plants, orchids, would be investigated in more detail and intensity in areas legally protected by authorities (nature reserves, national parks, natural monuments, wildlife sanctuaries, etc.), and whether the databases Scopus, Web of Science Core Collection, Russian Science Citation Index cover appropriately the majority of papers on orchids in Protected Areas on a global scale. There were found 331 publications on orchids in Protected Areas, including 72 from RSCI, 96 from Scopus, 163 from Web of Science Core Collection. A high percentage of the studies were conducted in the tropics, while vast temperate and subtropical regions (Northern Eurasia, Central and Western Asia, Northern and Central parts of North America, non-tropical Africa, and most parts of Australia) were poorly represented. Most studies were conducted in forests (in descending order of abundance-tropical, temperate, boreal), and were focused predominantly on the diversity and distribution of orchids in Protected Areas, followed by issues of taxonomy, structure and population dynamics, conservation threats of Orchidaceae, and orchid-consort interactions (insects-pollinators, trees-phorophytes, symbiotic fungi). It is concluded that the use of only the databases Scopus, Web of Science Core Collection and Russian Science Citation Index does not provide a sufficient amount of data to generalise comprehensive data about studies of orchids in Protected Areas at a global scale. In future systematic reviews of other, in non-English-language, international and national databases should be carried out.

“…Angraecoid orchids (Orchidaceae, Epidendroideae, Vandeae, Angraecinae) account for approximately 47.5% of the epiphytic orchid species in Tropical Africa (353 out of 743, Govaerts et al 2020). In the last decade, new angraecoid taxa have been described from the Guineo‐Congolian Region on a regular basis (Droissart et al 2014, Stévart et al 2014, D'haijère et al 2015, Ječmenica et al 2016, 2017, Descourvières et al 2018), in contrast to East Africa, which has attracted little attention (Farminhão and Cribb 2020). About 165 species of epiphytic orchids (out of a total of 268 orchids, or 61.6%) are known in Rwanda, (Fischer et al 2010) and about 180 species in Uganda (Govaerts et al 2020), with several being endemic to the western Rift Valley, also known as the Albertine Rift.…”

Here we describe and illustrate two new species of angraecoid orchids from East Africa, Tridactyle delepierrei and Ypsilopus iversenii, respectively from Albertine Rift (Rwanda and Uganda) and west Usambaras (Tanzania). The first species is closely allied to the three species of Tridactyle sect. Eggelingiae and to Tridactyle nalaensis. The second species is closely related to Y. leedalii from the southern highlands of Tanzania, and the affinities of these two species to other Ypsilopus are discussed. Diagnostic and morphological characteristics of these new species along with identification keys are provided, including those for the species of Tridactyle from East Africa and the Albertine Rift, and for the species of Ypsilopus sect. Ypsilopus. These new species are threatened with extinction based on the categories of the IUCN Red List, with T. delepierrei suggested to be Endangered (EN B1), while Y. iversenii would be Critically Endangered (CR). Our findings highlight the need for further orchidological inventories and taxonomical studies to support evidence-based conservation and management of the remaining montane forests of East Africa.

“…Existing literature reviews on the subject specifically relate to the progress made in ethnobotany (Chinsamy et al, 2011;Bhattacharyya & van Staden, 2018), the pollination of orchid species (Jersakova & Johnson, 2006;Micheneau et al, 2009;Van der Niet et al, 2015), and their taxonomy (Sanford & Adanlawo, 1973;Vermeulen, 1987;Linder, 1995;Pillon & Chase, 2007;Droissart et al, 2014;Simo-Droissart et al, 2018;Phillips & Bytebier, 2020). Therefore, it is essential to adopt a more global approach on studies concerning orchids in Africa and to identify future directions for scientific research in this area.…”

Worldwide scientific publications on the remarkably diverse Orchidaceae family are comprehensive, but Africa's craze for the taxon was only felt a few decades ago. This largest and threatened family of flowering plants is widely distributed in tropical areas and recognized by several authors for its environmental, ornamental, and medicinal importance. This review aims to identify research patterns on African orchids using co-citation analysis and bibliometric information visualization. 386 publications concerning African orchids listed in the Scopus database from 1968 to May 2020 were recorded and reviewed. The description of new orchid taxa, the adaptation of orchids to various pollinators and phylogeny emerged as the most discussed aspects. In total, 889 authors have invested in research on orchids in Africa. Johnson Steven D. was the most impactful author with h-index 37. Interestingly, several institutions were involved in these studies with a large dominance of the University of KwaZulu-Natal, a South African University. Future research efforts should target the identification of new orchid species and emphasize on orchid distribution, ecology, and species’ threats. They should also focus on developing efficient management and domestication strategies for orchid species to reduce threats to this family. The restoration and conservation planning of degraded orchid habitats are additional avenues to be explored by future research.
