  Field surveys on Chlorophytum in known and new localities were conducted across 70 districts within the four FTEA floral regions of Uganda between June 2019 and January 2020. The main aim was to map the distribution of taxa that existed in the country and document their habitats through a focused field survey. This was being done for the first time since the publication of the FTEA in 1997. Location coordinates and habitat characteristics were recorded, and voucher specimens collected for encountered plants. The study recorded 14 taxa consisting of 11 species. The U1 region recorded the highest species richness (11). Four species were recorded in U2, three in U4, and none in U3. Chlorophytum tordense, C. elgonense and C. blepharophyllum were the most frequent species while C. longifolium, C. gallabatense and C. miserum were the least frequent. Chlorophytum longifolium is reported here as a new record for Uganda. Chlorophytum species frequently occurred on sandy loams in undisturbed sites particularly in open woodland and wooded grassland habitats. Some eleven species previously recorded in the country were not encountered during this study, probably highlighting species extirpation.

  Abstract In northern European Cochlearia (Brassicaceae), considerable chromosome variation has taken place without corresponding morphological differentiation, resulting in an intricate species complex including two base chromosome numbers and several ploidies. Here, we investigate the situation in Iceland. The distribution, genetic structure, taxonomy and origin of the two Cochlearia cytotypes (2n = 12 and 2n = 14) present in Iceland are discussed. Chromosome counts indicate that both cytotypes occur along the coast, but 2n = 12 populations dominate (eight 2n = 12 vs. two 2n = 14 among the investigated populations), whereas 2n = 14 was reported for the two inland alpine populations investigated here. RADseq data support geographically structured genetic variation along the Icelandic coast and environmentally structured genetic differentiation between coastal and alpine populations. The alpine populations show genetic and morphological affiliation with C. groenlandica (2n = 14), which is widely distributed in the Arctic, but more comprehensive sampling is needed to draw conclusions concerning the taxonomic status of the Icelandic coastal plants. To uncover the origin of and phylogenomic relationships between the two chromosome variants, comparative whole-genome sequencing should be performed.

  Within genus Crinum L. there has been a lot of confusion, as to species delimitation, particularly in the Crinum rautanenianum complex comprising Crinum carolo-schmidtii, C. euchrophyllum, C. paludosum, C. rautanenianum, and also a specimen referred to as sp. A in Flora of Tropical East Africa. Maximum parsimony and Bayesian inference analyses were conducted on two datasets: nuclear DNA region (ITS) and five plastid regions (trnL-F spacer, trnL intron, rps16 intron, psbA-trnH spacer, and rps12-rpl20 spacer). Additionally, morphological characters based on herbarium specimens, pictures from the field, type specimens, and protologues were studied to establish diagnostic characters within the complex. Results from phylogeny and morphological characters provide evidence for the reinstatement of C. euchrophyllum, recognition of C. rautanenianum, C. carolo-schmidtii, C. paludosum, with a revisited description of C. rautanenianum, and the description of a new taxon: C. luangwense. A taxonomic revision of the C. rautanenianum complex is presented, including diagnostic characters, an identification key and distribution maps.

  Abstract Identification of conservation priorities is essential for conservation planning, especially as the biodiversity crisis develops. We aimed to support conservation prioritisation by addressing knowledge gaps for the genus Aloe in the Horn of Africa. Specifically, we developed a dataset of herbarium voucher specimens and occurrence data to estimate geographic distribution of 88 species of Aloe and used this to estimate extinction risk and establish the major threats to Aloe in this region. The resulting assessments, each published on the IUCN Red List, show that 39% of the species are threatened with extinction, and the principal threats are the expansion and intensification of crop farming and livestock farming, gathering of plants, and unintentional effects of logging and wood harvesting. We review ex situ conservation in botanic gardens and seed banks, revealing gaps in coverage and urgent priorities for collection, with 25 threatened Aloe species currently unrepresented in seed banks. Protected areas in the region offer limited coverage of Aloe distributions and the most recently designated protected areas are increasingly in regions that do not overlap with Aloe distributions. However, we show with a simple optimisation approach that even a modest increase in protected area of 824 square kilometres would allow representation of all Aloe species, although further data are needed to test the area required to ensure long-term persistence (resilience) of Aloe species.

  Speciation encompasses a continuum over time from freely interbreeding populations to reproductively isolated species. Along this process, ecotypes – the result of local adaptation – may be on the road to new species. We investigated whether three autotetraploid Cochlearia officinalis ecotypes, adapted to different habitats (beach, estuary, spring), are genetically differentiated and result from parallel ecotypic divergence in two distinct geographical regions. We obtained genetic data from thousands of single nucleotide polymorphisms (SNPs) from restriction-site associated DNA sequencing (RADseq) and from six microsatellite markers for 12 populations to assess genetic divergence at ecotypic, geographic and population level. The genetic patterns support differentiation among ecotypes as suggested by morphology and ecology. The data fit a scenario where the ancestral beach ecotype has recurrently and polytopically given rise to the estuary and spring ecotypes. Several ecologically-relevant loci with consistent non-random segregating patterns are identified across the recurrent origins, in particular around genes related to salt stress. Despite being ecologically distinct, the Cochlearia ecotypes still represent an early stage in the process of speciation, as reproductive isolation has not (yet) developed. A sequenced annotated genome is needed to specifically target candidate genes underlying local adaptation.

  The aims of this paper are three-fold: 1. To analyse the development and stability in vegetative traits such as leaf shape, growth and pigmentation patterns in three different morphotypes (defined by leaf shape and pigmentation) of the Ledebouria revoluta complex. 2. To discuss the putative function of leaf mottling/variegation. 3. To discuss plasticity in these traits in relation to taxonomy and species delimitation within the complex. Clones were analysed in a cultivation experiment with two nitrogen levels (N1 and N2), three morphotypes (A, B & C) and two light levels (L1 and L2). Anthocyanins were found in hypodermal cells, particularly in the proximal (i.e. young) parts of the leaf. The red pigmentation faded out in distal (i.e. more mature) parts of the leaf. Furthermore, older, outer leaves had more pigmentation than younger, inner leaves. Increased nitrogen availability had no effect on leaf pigmentation. Some plants developed significantly more red pigmentation adaxially at high light intensities, whereas abaxial pigmentation was unaffected by light intensity. The pigmentation of the two sides of a leaf therefore seems to be regulated independently and may accordingly serve different functions for the plants. Adaxial pigmentation (mainly in the form of mottling, pigmentation mainly in spots) may serve as photoprotection, whereas abaxial pigmentation (mainly in the form of variegation, pigmentation mainly in bands) may possibly be aposematic. In the field a high degree of intrapopulational variation in pigmentation patterns was observed. This might be due to local habitat heterogeneity and gene flow or frequency dependent selection. Characters relevant to taxonomy (leaf shape, pigmentation pattern) only changed to a limited extent, suggesting that the vegetative traits are genetically based. The three different morphotypes were easily recognized unrelated to the different treatments. Whether a formal taxonomic status is justified for the different morphotypes will need more plant material and genetic data and cannot be decided based on this study.

  Sister group relations of Ethiopian species of Anthericum and Chlorophytum and variation patterns in the C. gallabatense and C. comosum complexes are studied using molecular phylogenetic analyses, morphometrics, and scanning electron microscopy of seed surfaces. Our results indicate that molecular data largely support previous morphological conclusions, and that speciation has occurred in Ethiopia at least three times in Anthericum and repeatedly within different subclades of Chlorophytum. Areas particularly rich in endemic species are the lowland area around Bale Mountains in SE Ethiopia and in the Beninshangul Gumuz regional state in W Ethiopia near the border to Sudan. A new species, Chlorophytum mamillatum sp. nov., is described, and the names Chlorophytum tordense Chiov. and Chlorophytum tetraphyllum f. are re-erected.

  Background The genus Aloe is renowned for its medicinal and cosmetic properties and long history of use. Sixty-three Aloe species occur in Kenya, of which around 50 % are endemic. Several species of aloes are threatened with extinction and knowledge about their use is of major importance for sound conservation strategies. The main aims of this study were to assess the biocultural value of Aloe in Kenya by documenting local uses of aloes and evaluating how the vernacular names reflect the relative importance in different ethnic groups. Methods Ethnobotanical and ethnotaxonomical data were collected using field observations and semi-structured interviews. Information was collected by interviewing 63 respondents from nine different ethnic groups, representing different ages, gender and occupations. Statistical analyses were performed using R version 3.1.2. Results A total of 19 species of Aloe were found in the study area, of which 16 were used. On the generic level Aloe was easily distinguished. At species level, the local and scientific delimitation were almost identical for frequently used taxa. Aloe secundiflora, with 57 unique use records was the most important species. The two most frequently mentioned Aloe treatments, were malaria and poultry diseases. In our study area neither age nor gender had a significant influence on the level of knowledge of Aloe use. Finally, no correlation was found between extent of use and people’s perception of decrease in local aloe populations. The aloes are highly appreciated and are therefore propagated and transported over large areas when people relocate. Conclusion Biocultural value is reflected in the ethnotaxonomy of Aloe in Kenya. Different ethnic groups recognise their most-valued Aloe at the genus level as “the aloe” and add explanatory names for the other species, such as the “spotted aloe” and the “one-legged aloe”. Widespread species of Aloe have the highest number of uses. There is no obvious correlation with high use and decrease in abundance of aloes locally, and we found no compelling evidence for local uses causing devastating damage to populations of the 19 species in use, whereas habitat loss and commercial harvesting appear to be of urgent concern for these important plants.

  Six new taxa of Chlorophytum (five from Zambia and one from Malawi) are described, namely C. bulbinifolium Hoell & Nordal, C. zambiense Bjorå & Nordal, C. chelindaensis Kativu & Nordal, C. clarae Bjorå & Nordal, C. blepharophyllum Schweinf. ex Baker subsp. rubropygmaeum Bjorå & Nordal, and C. blepharophyllum Schweinf. ex Baker subsp. pendulum Hoell & Nordal. The sister group relationships of the new taxa were studied by cladistic analyses of nuclear and chloroplast DNA sequences. Chlorophytum bulbinifolium has an isolated position in the cladogram. It is morphologically closest to C. subpetiolatum (Baker) Kativu, but differs by its narrow succulent leaves and smaller flowers. Chlorophytum zambiense is nested with C. andongense Baker, C. macrosporum Baker, and C. viridescens Engl., but differs by being more slender and by having ebracteate peduncles and smaller flowers. Chlorophytum chelindaensis belongs in the C. colubrinum Engl. complex, differing from C. colubrinum by its smaller habit and hairy leaves. Chlorophytum clarae is in a clade with C. pusillum Schweinf. ex Baker and C. pauper Poelln. It is morphologically closest to C. macrophyllum Asch., but has globose capsules and smaller irregularly folded seeds.

  Norwegian universities have trained students and other scholars from the South within fields related to African plant diversity through the last decades. The activities were funded by NUFU, the Norwegian Council of Universities Committee for Development Research and Education, and 30 students successfully obtained PhD degrees in taxonomy and other biodiversity related fields, and all but a few have entered into scientific position at universities or other relevant research institutes in Africa. Most collaboration involved Zimbabwe, Malawi, Ethiopia, and Kenya, and though successful, they all faced the challenges of multi-institutional and multi-cultural teaching and research collaboration. Basic research within botanical diversity is better taken care of when the university councils own and administer the projects, compared to the alternative ownership by aid agencies.
