“…This species has spatulate or oblong leaves with very short petioles, the characters being typical of Sesuvium portulacastrum . For this reason, S. brevifolium is merged with S. portulacastrum subsp. portulacastrum, this being in agreement with other accounts (Hooker 1849, Welwitsch in Oliver 1871, Bohley et al 2017). …”

Diagnostics, taxonomy, nomenclature and distribution of perennial Sesuvium (Aizoaceae) in Africa

The taxonomy of perennial Sesuvium species in Africa has been poorly investigated until now. Previously five perennial species of Sesuvium were recognised in Africa (S. congense, S. crithmoides, S. mesembryanthemoides, S. portulacastrum, and S. sesuvioides). Based on the differing number of stamens, S. ayresii is accepted here as being distinct from S. portulacastrum. Field observations in Angola also led the authors to conclude that S. crystallinum and S. mesembryanthemoides are conspecific with S. crithmoides. A new subspecies, Sesuvium portulacastrum subsp. persoonii, is described from West Africa (Cape Verde, Gambia, Guinea-Bissau, Mauritania, Senegal). The molecular phylogeny indicates the position of S. portulacastrum subsp. persoonii within the “American lineage” as a part of the Sesuvium portulacastrum complex which needs further studies. A diagnostic key and taxonomic notes are provided for the six perennial species of Sesuvium found in Africa and recognised by the authors (S. ayresii, S. congense, S. crithmoides, S. portulacastrum subsp. portulacastrum, S. portulacastrum subsp. persoonii, S. verrucosum and the facultatively short-lived S. sesuvioides). The distribution of S. crithmoides, previously considered to be endemic to Angola, is now confirmed for the seashores of Republic of Congo and DR Congo. The American species S. verrucosum is reported for the first time for Africa (the Macaronesian islands: Cape Verde and the Canaries). It is locally naturalised in Gran Canaria, being a potentially invasive species. These findings as well as new records of S. verrucosum from Asia and the Pacific Islands confirm its proneness to transcontinental introduction. Lectotypes of S. brevifolium, S. crithmoides, S. crystallinum and S. mesembryanthemoides are selected. The seed micromorphology and anatomy of the perennial African species is studied. Compared to the seeds of some annual African Sesuvium investigated earlier, those of perennial species are smooth or slightly alveolate. The aril is one-layered and parenchymatous in all species and usually tightly covers the seed. The aril detachments from the seed coat that form a white stripe near the cotyledon area easily distinguish S. verrucosum from other species under study.

“…Vogel 83 , the type of C. subuliflora , has two sheets, one of which is C. macroura (K000412044!). Both sheets are labelled ‘Fernando Po’ [= Bioko], but their origin is somewhat doubtful, for Bentham (in Hooker, ) states in the protologue of C. subuliflora : ‘Fernando Po, on the seashore, and, apparently the same species, at Abòh, growing in the water, Vogel ’. The latter locality is in Nigeria.…”

Taxonomy and phylogenetics ofCuviera(Rubiaceae-Vanguerieae) and reinstatement ofGlobulostyliswith the description of three new species

et al. 2013

Generic circumscriptions in tribe Vanguerieae (Rubiaceae) have been under discussion for a long time. Recent molecular studies, while providing new insights, have not yet solved all the problems. In this study, the taxonomy and phylogenetics of the genus Cuviera s.l. are investigated. On the basis of molecular and morphological evidence, Cuviera is restricted to a group of ten West and Central African species. Globulostylis, previously included in Cuviera, is reinstated as a distinct genus, with eight species from Central Africa. Both genera are revised; the latter includes three new species (G. dewildeana, G. rammelooana and G. robbrechtiana) and two new combinations (G. leniochlamys and G. uncinula). The close relationship of Cuviera s.s. and Globulostylis to Vangueriella is shown. Six aberrant species (most from East Africa) are excluded from Cuviera, but further work is needed before they can be confidently assigned to other genera. © 2013 The Linnean Society of London, Botanical Journal of the Linnean Society, 2013, 173, 407–441.

“…Undescribed specimens of Tornabenea were first collected by Vogel in 1841. In 1849, Parlatore, with material from a single species ( Tornabenea insularis ), established a new tribe with a monospecific genus, Tetrapleura [ 29 ]. The name was a homonym and renamed to Tornabenea by Parlatore [ 30 ].…”

The Macaronesian islands constitute an enormous reservoir of genetic variation of wild carrots (subtribe Daucinae; Apiaceae), including 10 endemic species, but an accurate understanding of the diversification processes within these islands is still lacking. We conducted a review of the morphology, ecology, and conservation status of the Daucinae species and, on the basis of a comprehensive dataset, we estimated the genome size variation for 16 taxa (around 320 samples) occurring in different habitats across the Macaronesian islands in comparison to mainland specimens. Results showed that taxa with larger genomes (e.g., Daucus crinitus: 2.544 pg) were generally found in mainland regions, while the insular endemic taxa from Azores and Cabo Verde have smaller genomes. Melanoselinum decipiens and Monizia edulis, both endemic to Madeira Island, showed intermediate values. Positive correlations were found between mean genome size and some morphological traits (e.g., spiny or winged fruits) and also with habit (herbaceous or woody). Despite the great morphological variation found within the Cabo Verde endemic species, the 2C-values obtained were quite homogeneous between these taxa and the subspecies of Daucus carota, supporting the close relationship among these taxa. Overall, this study improved the global knowledge of DNA content for Macaronesian endemics and shed light into the mechanisms underpinning diversity patterns of wild carrots in the western Mediterranean region.
