Based on results from recent molecular phylogenetic studies, Solitaria ramellata (F.N. Williams) Gang Yao, S. forrestii (Diels) Gang Yao and S. rhodantha (Pax & Hoffmann) Gang Yao, three new combinations of Caryophyllaceae, are proposed. Additionally, the two names S. ramellata and S. rhodantha are lectotypified.

Following recent molecular phylogenetic studies in Old World Gesneriaceae the nomenclatural implications for names in Henckelia are examined. New combinations are made in Codonoboea and Loxocarpus to account for species now excluded from Henckelia. A list is presented in which the current position of all species hitherto assigned to Henckelia is given, including the new combination Henckelia rotundata (Barnett) D.J.Middleton & Mich.Möller. A new combination in Oreocharis is made.

The classification of the genera belonging to the doryctine tribe Rhaconotini (Braconidae) is updated. The following new taxa are described: Troporhaconotus gen. nov. (with 12 species), Afroipodoryctes subgen. nov. (of Ipodoryctes Granger, 1949) (with three species), Hexarhaconotinus subgen. nov. (of Rhaconotinus Hedqvist, 1965) (with ten species), Bathycentor zimbabwensis sp. nov., Ipodoryctes (Afroipodoryctes) reunionus sp. nov., I. (A.) saintphilippensis sp. nov., Platyspathius (Platyspathius) venezuelicus sp. nov., P. (P.) ranomafanus sp. nov., Rhacontsira haeselbarthi sp. nov., Rh. mozambiquensis sp. nov., Rh. saigonensis sp. nov. and Rh. toamasina sp. nov. The generic status of Euryphrymnus Cameron, 1910 is resurrected. The generic name Aptenobracon Marsh, 1965 is synonymised under Rhaconotus Ruthe, 1854 (syn. nov.); Rhaconotus asiaticus Belokobylskij, 1990 is synonymised under Rh. kerzhneri Belokobylskij, 1985 (syn. nov.). The new name, Rhaconotinus austrochinensis nom. nov., is suggested for the preoccupied name Rhaconotus chinensis Chen & Shi, 2004 (December) not Rhaconotus chinensis Belokobylskij & Chen, 2004 (June). New species contents, in many cases with numerous new combinations, are suggested for the genera Bathycentor Saussure, 1892, Euryphrymnus Cameron, 1910, Ipodoryctes Granger, 1949, Rhaconotinus Hedqvist, 1965 and Rhaconotus. The tribe Leptorhaconotini is synonymised with Rhaconotini based on previously published molecular phylogenetic studies, though we leave this group within the subtribe Leptorhaconotina.

Based on a previous molecular phylogenetic analysis, Cryptantha, an herbaceous plant genus of the family Boraginaceae, subtribe Amsinckiinae, was split into five genera: Eremocarya, Greeneocharis, Johnstonella, Oreocarya, and a reduced Cryptantha, the last in two separate clades. As a result of this study, Johnstonella was expanded to 13 species and 15 minimum-rank taxa, these formerly classified in Cryptantha s.l. More recent analyses of this complex, with an increased sample size and high-throughput sequence data, indicate that four additional Cryptantha species not previously sampled—C. albida, C. mexicana, C. texana—plus what was originally identified as C. hispida nest within Johnstonella with strong support. However, the identity of C. hispida used in this analysis is now in doubt. The material used likely represents a new species, in the process of being investigated. Two additional species not sequenced to date—C. geohintonii and C. gypsites—are clearly close relatives of C. albida and C. mexicana, based on morphological similarity. In order to maintain monophyly of genera, we here make new combinations in transferring four of these species from Cryptantha to Johnstonella, with the new combinations Johnstonella albida, J. geohintonii, J. gypsites, and J. mexicana. We delay the transfer of Cryptantha texana to Johnstonella because of its morphological similarity to other species that clearly nest within Cryptantha s.s. These same molecular phylogenetic studies may also support the transfer of two previously recognized Johnstonella species—J. echinosepala and J. micromeres—to Cryptantha, one to each of two separate clades. Additional phylogenetic studies focusing on some of these taxa are needed to confirm the position of these latter three species and the possible recognition of a new genus in the complex.

Recent molecular phylogenetic studies showed that the genus Sansevieria (excluding S. sambiranensis) forms a monophyletic clade nested within the paraphyletic genus Dracaena. Consequently, the genus Sansevieria was sunk into the genus Dracaena and new combinations were published to accommodate the transfer of taxa from Sansevieria into Dracaena. Since the inclusion of Sansevieria into Dracaena, new taxa have been published in Sansevieria. This paper presents fourteen name changes including twelve new combinations in Dracaena and two rank adjustments, one new synonym, and one lectotypification aiming at further standardisation of the taxonomy of Dracaena.

Background – During the past decade several molecular phylogenetic studies tackled the complex relationships within tribe Cypereae. Based on these studies, previously accepted segregate genera such as Pycreus were sunk into the genus Cyperus. Recently, while revising the West African species of Cyperus, three taxa previously placed in Pycreus were identified for which a name in Cyperus is lacking.Methods – The taxonomic changes are performed according to the International Code of Nomenclature for algae, fungi, and plants.Results – Three new combinations in Cyperus are made for names currently placed in Pycreus.

Recently, molecular phylogenetic studies have revolutionized the generic concepts in Parmeliaceae and in lichen forming fungi in general. In the present study, the generic delimitation in the Hypotrachyna clade is revised using a molecular phylogeny of nuclear ITS, LSU and mitochondrial SSU rDNA sequences of 88 hypotrachynoid taxa. Morphological and chemical features are also revised in each group. 118 sequences are newly generated for this study. Our phylogenetic analyses show the polyphyly of Hypotrachyna as currently circumscribed which falls into four well-supported and one unsupported clade. Cetrariastrum, Everniastrum and Parmelinopsis are nested within Hypotrachyna s. lat., Parmelinopsis being also polyphyletic and nested in one of the Hypotrachyna clades. Cetrariastrum is monophyletic but clustered within Everniastrum. Two alternative hypotheses tests significantly rejected the monophyly of these three genera. As a consequence, the genera Cetrariastrum, Everniastrum, and Parmelinopsis are reduced to synonymy with Hypotrachyna. Furthermore, we here propose an alternative classification to recognize the well-supported clades at subgeneric level and leave the remaining species unclassified within the genus. Five new subgenera are proposed: Hypotrachyna subgen. Cetrariastrum, Hypotrachyna subgen. Everniastrum, Hypotrachyna subgen. Longilobae, Hypotrachyna subgen. Parmelinopsis, and Hypotrachyna subgen. Sinuosae. Forty-nine new combinations are proposed.

Panus is a genus of the order Polyporales with a gilled hymenium. Although Panus was earlier considered as a sub genus of the genus Lentinus, molecular phylogenetic studies support the independent status of the genus. As a result, many species were transferred from Lentinus to Panus. Many more species of Lentinus that are more related to Panus, still await critical taxonomic studies and formal transfers. Morphological and molecular data obtained from L. bambusinus and L. roseus reveal that these are Panus species. Two new combinations in the genus Panus are proposed here.

Eulophia (Eulophiinae; Epidendroideae) has been found in molecular phylogenetic studies to be non-monophyletic. Here, we propose to combine it with Acrolophia, Cymbidiella, Eulophiella, Geodorum, Oeceoclades and Paralophia and discuss the characters that have been used previously to discriminate among these genera, demonstrating that none of them is without exceptions. Given the incongruence found in the molecular phylogenetic studies between plastid and nuclear results, a broader circumscription of Eulophia is more likely to be stable. In total, 35 new combinations/names are required for the expansion of Eulophia to include these other genera.

Recent molecular phylogenetic studies have indicated that Aconitella is embedded in Consolida, which in turn is embedded in Delphinium. We choose not to split the genus Delphinium (c. 300 species), as it is horticulturally and pharmaceutically important, by conserving a broad Delphinium by transferring the names from Consolida and Aconitella to Delphinium s.lat., and more precisely in the resurrected D. subg. Consolida. Including 58 species of Aconitella and Consolida within Delphinium causes fewer nomenclatural overall changes than do alternative schemes because most of the species of Aconitella and Consolida were once named under the name Delphinium. We present here the list of synonyms for the species once named under Consolida or Aconitella and gather the information relative to the types of these names. Two new combinations are provided, and 21 lectotypes are designated here.

Based on the published data of molecular phylogenetic studies of the tribe Cariceae Dumort. genera (Cyperaceae), obtained by an international collaboration (The Global Carex Group, 2016; et al.), and morphological characters of the genera (Kukkonen, 1990; and others), new nomenclatural combinations and replacement names in the genus Carex L. are published for 11 species, one subspecies and two sections previously included in the genus Kobresia Willd.
