Valid publication of the name Helicia falcata (Proteaceae)

Helicia falcata C. Y. Wu was not validly published in 1977 because two gatherings, one flowering and one fruiting, were simultaneously designated as types in the protologue. This name is validated here by designating the flowering specimen as the holotype.     

Valid publication of the name Atalantia acuminata (Rutaceae), endemic to southwestern China and northern Vietnam

Atalantia acuminata C. C. Huang, originally described in 1991, was an invalidly published name, because two collections were designated as the type and the herbarium in which the type was conserved was not specified. The name is validated here, with the flowering specimen kept in IBSC designated as the holotype.     

假巴戟名称的合法化以及对糠藤后选模式的指定

假巴戟（Morinda shuanghuaensis C．Y．Chen et M．S．Huang）和糠藤（Morinda howiana S．Y．Hu）为茜草科（Rubiaceae）巴戟天属的两个中国特有种。发表于1976年的假巴戟的名称因原作者指定了两份标本作为模式标本（花模式和果模式）而为不合法名称,本文将其合法化,并根据原始描述将其果模式指定为模式。同样,糠藤也被指定具有两个模式,但是因其发表时间早于1958年1月1日,因此并不违背最新版《国际植物命名法规》（维也纳法规）,但是为了规范植物名称,避免更多的混淆,我们依据其原始描述将其花模式指定为后选模式。     

Lectotypification of the Linnaean name Hypochaeris maculata (Asteraceae)

The typification of the name Hypochaeris maculata L. is discussed. A specimen from the Linnaean Herbarium (LINN) is designated as the lectotype.     

Lectotypification of the Linnaean name Fagus castanea (Fagaceae)

The typification of the name Fagus castanea L. (Fagaceae) is discussed. A specimen from the Linnaean Herbarium (no. 1130.1, LINN!) is designated as lectotype.     

Type designation of the oaks Quercus ballota and Q. rotundifolia (Fagaceae)

The names Quercus ballota and Q. rotundifolia (Fagaceae), referring to taxa sometimes considered conspecific with the widely distributed Q. ilex, are discussed and typified. A specimen preserved at MPU is designated as the lectotype of Desfontaines's name Q. ballota. Lamarck's name Q. rotundifolia is neotypified using a specimen preserved at VAL, with several duplicates in other European herbaria.     

Validation of Scrophularia macrocarpa (Scrophulariaceae) endemic to southwestern China

Scrophularia macrocarpa P. C. Tsoong, originally described from Sichuan, China, was not validly published in 1979 because two type specimens (one fruiting, one in flower) were designated. To enable formal use of the name, the species name is validated here, with the fruiting specimen designated as the holotype.     

Carex tomentosa versus C. filiformis (Cyperaceae): the long‐standing debate comes to its happy end

The type of Carex filiformis is an illustration, which is pluri‐interpretable and therefore an epitype is designated here. As epitypified, C. filiformis L. becomes synonymous with Carex montana L. (the latter getting priority), and therefore not the correct name for Carex tomentosa L. as stated by Nelmes and other authors. Carex tomentosa is the accepted name for the taxon sometimes referred to as C. filiformis.

Typification of three names in Antirrhinum (Plantaginaceae: Antirrhineae)

Typification of the names Antirrhinum barrelieri Boreau, A. controversum Pau and A. litigiosum Pau (Antirrhineae, Plantaginaceae) is needed to clarify the use and concept of these three names. The origin of a misinterpretation of the name A. barrelieri, which conditioned the subsequent use of these three names, is discussed. The previous ‘lectotype’ of A. barrelieri designated by Rothmaler from a Barrelier's illustration is shown to be ineffective, being contrary to Art. 9.12 of the ICN, and therefore a lectotype is designated from a syntype preserved in the herbarium of the Muséum des sciences naturelles d'Angers (France) at ANG. The Pau's names A. controversum and A. litigiosum have not been typified before, and lectotypes are here designated from specimens preserved at P and MA, respectively. As a consequence, the name A. litigiosum should be treated as a later heterotypic synonym of A. barrelieri.     

Typification of the Linnaean name Ononis crispa and the related O. zschackei (Fabaceae)

The typification of the Linnaean name Ononis crispa and the related O. zschackei (Fabaceae) is discussed. Original material for O. crispa was traced at LINN, but found to be heterogeneous. In addition, the illustration by Magnol cited in the protologue represents O. aragonensis. The name is lectotypified using a specimen at LINN to preserve the current usage of the name and to avoid any ambiguity in the interpretation of the lectotype, an epitype is selected. Since no original material is extant for the name O. zschackei, a neotype is designated from a specimen preserved at P and collected in Mallorca (Balearic Islands, Spain).     

大叶可爱花,中国爵床科一新记录种

首次报道中国爵床科（Acanthaceae）一新记录种：大叶可爱花（Eranthemum macrophyllum Wall.ex Nees）。该种原记载分布于缅甸,在中国仅见于云南省铜壁关省级自然保护区。为名称Eranthemum macrophullus指定了后选模式。     

The late-flowering phenotype of FRIGIDA and mutations in LUMINIDEPENDENS is suppressed in the Landsberg erecta strain of Arabidopsis

The late-flowering phenotype of mutations in the LUMINIDEPENDENS (LD) gene and the late flowering caused by the naturally occurring dominant gene FRIGIDA (FRI) are suppressed in the Landsberg erecta (Ler) strain of Arabidopsis thaliana. This suppression is dependent on a locus on chromosome 5 designated FLC. Of the ecotypes tested, only the Ler strain contains the suppressor allele of FLC; ld mutations and FRI cause late flowering in the other genetic backgrounds. The allele at FLC also has a moderate effect on flowering time in the absence of FRI or ld mutations. The flowering time effects of FLC are gene dosage dependent.     

Lectotypification of the name Epipactis leptochila (Orchidaceae)

It is argued that an alleged lectotype of the name Epipactis leptochila (designated in 1981) is actually a neotype, as the published plate in question did not appear in print until 14 years after the protologue. A herbarium specimen at BM represents original material that was used by Godfery when describing the E. leptochila, and in all probability the same is true for the original watercolour painting (now deposited at the Natural History Museum, London) from which the published plate was eventually reproduced. Therefore, a part of the herbarium specimen is designated as lectotype.     

Notes on Plecoptera (19) Isoperla lugens (Klapalek, 1923), replaces I. alpicola Brinck, 1949

A male lectotype and several paralectotypes of Chloroperla lugens Klapálek, 1923 are designated. The species is transferred to genus Isoperla and is the valid name for Isoperla alpicola Brinck, 1949.
