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.

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.

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.

Name Changes

Alterations for the year 1986 to the inventory maintained in PRECIS are reported for bryophytes, pteridophytes and monocotyledons, and for a few dicotyledons. For the cryptogams and monocots there are 77 newly described species or infraspecific taxa, 27 names brought back into use, and nine species newly reported for southern Africa, resulting in 113 additions to the total list of species. Five species were removed because they were mistakenly recorded from the area. Seventy-five names have gone into synonymy, there are 52 new combinations, and there are 35 orthographic corrections, resulting in 237 alterations to the list of species. The total of 355 additions, deletions and alterations represents about 5% of the total species and infraspecific taxa for the cryptogams and monocots.

Recent molecular phylogenetic studies have confirmed that Microlejeunea (Spruce 1884: 286) Stephani (1888: 61) is a good genus which is closely related to Lejeunea Libert (1820: 372) (Dong et al. 2013; Wei 2013). Microlejeunea is distinguished from Lejeunea by the presence of ocelli in the leaf lobe, transverse section of the stem consisting of seven cortical cells and three medullary cells, and keel of the female bract usually winged (Wei & Zhu 2013). Although about 50 species are currently accepted in Microlejeunea, most of them are still poorly known. Microlejeunea subaphanes Herzog (1950: 70) is a very rare species known only from the type specimen collected in São Paulo, Brazil (Herzog 1950; Gradstein & Costa 2003), and its identity is not clear (Bischler et al. 1963). Our examination of its type specimen showed that M. subaphanes does not belong to Micrololejeunea because of the distal hyaline papilla of the leaf lobule, pycnolejeuneoid gynoecial innovation, keel of female bract not winged, transverse section of the stem consisting of 7−9 cortical cells and 4−5 medullary cells, and absence of ocelli in the leaf lobe (Fig. 1). Further critical study revealed that M. subaphanes is conspecific with Cheilolejeunea decursiva (Sande Lacoste 1855: 522) Schuster (1963: 112), which is widespread in tropical Africa and rare in Asia (Borneo, Java, Sri Lanka), Australia and Oceania (Fiji, Hawaii) (Zhu & Lai 2005).

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.

Based on extensive herbarium, field, botanical illustration, and molecular phylogenetic research, five genera and eight species are recognised for the Neotropical Haemodoraceae. New taxa include Cubanicula Hopper et al., Xiphidium pontederiiflorum M.Pell. et al. and Schiekia timida M.Pell. et al. Two new combinations are made, Cubanicula xanthorrhizos (C.Wright ex Griseb.) Hopper et al. and Schiekia silvestris (Maas & Stoel) Hopper et al. We also correct the author citation for Xiphidium, provide the necessary typifications for several names and present an updated identification key, comments, and photo plates for all species. Finally, we provide high-quality illustrations for most of the recognised species and their diagnostic characters.

Molecular phylogenetic analyses based on nuclear ITS rDNA and mitochondrial SSU rDNA sequences from 32 specimens representing Parmotrema pseudoreticulatum, P. reticulatum and P. clavuliferum from Africa, Asia, Australia, and Europe are reported. Samples from western Europe and South Africa formed an independent monophyletic group, which belongs to P. pseudoreticulatum, a species not accepted by some recent authors, that has only been reported from Portugal, Spain and Morocco. In contrast, P. reticulatum and P. clavuliferum, both widely distributed taxa, formed a monophyletic clade, supporting the synonymy already proposed on the basis of morphological features.

AbstractNon-saxicolous lecideoid lichens form a diverse and polyphyletic group of species with a worldwide distribution. The phylogenetic relationships of the taxa and major clades are still largely unresolved. Here we introduce a new genus Palicella Rodr. Flakus & Printzen for Lecidea glaucopa Hook. f. & Tayl. and two closely related species. Our molecular phylogenetic results, based on maximum likelihood and Bayesian phylogenetic trees, and a combined dataset of five gene loci (ITS, nrLSU, mrSSU, RPB1 and RPB2), indicate that Palicella forms a monophyletic clade sister to Lecanora symmicta and Pyrrhospora quernea. The new genus is characterized by biatorine apothecia, which are often darkened (by the pigment Cinereorufa-green), an exciple of radiating, narrow hyphae with strongly elongate lumina, a hymenium with branched and sparsely anastomosed paraphyses, an ascus with a broad axial body surrounded by a distinct darker staining layer, and narrowly ellipsoid ascospores. Atranorin is present in all, usnic acid in two and pannarin in one species of the genus. Three new combinations are proposed: Palicella filamentosa (Stirt.) Rodr. Flakus & Printzen, P. glaucopa (Hook. f. & Taylor) Rodr. Flakus & Printzen, and P. schizochromatica (Pérez-Ortega, T. Sprib. & Printzen) Rodr. Flakus & Printzen. The molecular phylogenetic analysis confirms that Lecidea hercynica Hauck & Schmull is a synonym of P. filamentosa. An identification key to the species is provided.

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.
