Cyclamen libanoticum, a species that knows its identity!
The species limits and infraspecific DNA sequence diversity of Cyclamen libanoticum was examined. Analysis of the chloroplast DNA from six regions shows that, in C. libanoticum, only one base-pair difference is found among samples within the analysed 7066 base-pairs. This one base-pair difference (9 ‘A’s vs 10 ‘A’s) was found in the samples collected from a single site and could represent a very minor change in DNA sequence or even show the limits or accuracy of the sequencing system used. C. libanoticum is highly distinct from other congeners in DNA sequence

The complete plastome of Hyacinthoides non-scripta (L.) Chouard ex Rothm. (Asparagaceae)
The whole plastome sequence ofHyacinthoides non-scripta, was assembled and annotated in this study.This is the first complete plastid genome for the genusHyacinthoides. The plastome is 155,035 bp longand consists of a large single-copy (LSC) region spanning 83,947 bp, a small single-copy (SSC) regionspanning 18,496bp, and two inverted repeat (IR) regions, each of which is 26,296bp in length. Thereare 132 genes annotated in the plastome, of which the protein-coding geneinfAhas pseudogenized

The complete plastome of Daphne laureola L. (Thymelaeaceae)
The complete plastome sequence for the type species of Daphne, Daphne laureola, was assembled and annotated in this study. The total length of the D. laureola plastome is 171,613 bp and comprises the large single copy (LSC) spanning 85,316 bp, the small single copy (SSC) spanning 2855 bp, and two inverted repeat (IR) regions each of 41,721 bp length. The SSC contains only two genes: ndhF and rpl32. This sequence extends the list of Thymelaeaceae plastomes to be used in future systematic studies of the family and is the first European species to be sampled

The complete chloroplast genome of Narcissus poeticus L. (Amaryllidaceae: Amaryllidoideae)
The first complete chloroplast genome sequence for Narcissus is assembled and annotated in this study. The total length of the N. poeticus chloroplast genome is 160,099 bp and comprises the large single copy (LSC) spanning 86,445 bp, the small single copy (SSC) spanning 16,434 bp, and two inverted repeat regions each of 28,610 bp length. The truncated copy of ycf1 before the junction between IRB and SSC was 1,277 – 2,428 bp longer than in other included Asparagales samples. A potential pseudogene, cemA, was also identified. This is the first reported plastome for Amaryllidaceae subfamily Amaryllidoideae

The complete plastome of the South African species, Amaryllis belladonna L. (Amaryllidaceae)
The complete plastome sequence of Amaryllis belladonna L. is assembled and annotated. This is the type species of Amaryllis and therefore the type of the family Amaryllidaceae and as such, is important to document the phylogenetic position of the family. The plastome sequence has a length of 158,145 bp, with the large single copy (LSC) regions comprising 85,963 bp, the small single copy (SSC) 18634 bp and two identical inverted repeats (IR) regions each of 26,774 bp. Phylogenetic analysis fully resolved Amaryllis in a clade with Crinum L. in the Amaryllidoideae, as expected, with the Allioideae as a sister group. Agapanthus (Agapanthoideae) is a sister to the other two subfamilies in the Amaryllidaceae. The phylogenetic tree produced corresponds to previous topologies based on plastome molecular markers including matK, ndhF and rbcL. This is the first paper reporting the whole plastome comparison of the type genera of all three subfamilies in the Amaryllidaceae

Comparative plastomics of Amaryllidaceae: inverted repeat expansion and the degradation of the ndh genes in Strumaria truncata Jacq.
Amaryllidaceae is a widespread and distinctive plant family contributing both food and ornamental plants. Here we present an initial survey of plastomes across the family and report on both structural rearrangements and gene losses. Most plastomes in the family are of similar gene arrangement and content however some taxa have shown gains in plastome length while in several taxa there is evidence of gene loss. Strumaria truncata shows a substantial loss of ndh family genes while three other taxa show loss of cemA, which has been reported only rarely. Our sparse sampling of the family has detected sufficient variation to suggest further sampling across the family could be a rich source of new information on plastome variation and evolution
An investigation of large-leaved Gunnera L. (Gunneraceae) grown outside in Britain and Ireland
A molecular investigation of large-leaved Gunnera growing outside in Britain and Ireland was conducted. Two low-copy nuclear CYCLOIDEA-like genes (CYC-like 1 and CYC-like 2) and two chloroplast DNA regions (matK and psbD-trnT) were sequenced for 271 samples of Gunnera. While it was confirmed that genuine G. tinctoria is growing both in cultivation and in the wild, the results support recently published morphological and historical findings that the species G. manicata appears no longer to be present in Britain and Ireland. Instead, the plant under this name is G. × cryptica, a hybrid between G. manicata and G. tinctoria. The implication of this discovery for legislation on invasive non-native species where G. manicata and G. tinctoria are listed is explored

Jumping through the hoops: the challenges of daffodil (Narcissus) classification
Abstract Hoop-petticoat daffodils are a morphologically congruent group comprised of two distinct lineages in molecular phylogenetic trees of Narcissus. It is possible that the morphological similarity is a product of both historic and current low-level gene flow between these lineages. For the first time, we report population sampling from across the entire range of distribution covering the Iberian Peninsula and Morocco. In total, 455 samples were collected from 59 populations. Plastid DNA sequences of matK and ndhF were generated alongside 11 microsatellite loci to permit comparison between plastid and nuclear lineage histories. The plastid DNA phylogenetic tree was highly congruent with previous molecular studies and supported the recognition of these two lineages of hoop-petticoat daffodils as separate sections. Assignment of samples to sections sometimes differed between plastid DNA and (nuclear) microsatellite data. In these cases, the taxa had previously been the focus of dissent in taxonomic placement based on morphology. These discrepancies could be explained by hybridization and introgression among the two lineages during the evolution of hoop-petticoat daffodils, and shows that placement of species in sections is dependent on the source of data used. This study underlines the complex evolutionary history of Narcissus and highlights the discrepancies between floral morphology and phylogeny, which provides a continuing challenge for the systematics of Narcissus
Golgotha
Postal que reproduce una pintura del año 1884 de Mihaly Munkácsy. Representa la Crucifixión de Cristo en el Monte Gólgota. A la derecha aparece Cristo crucificado, junto a Dimas y Gestas. A los pies se encuentra la Virgen MarÃa, acompañada por San Juan Bautista, MarÃa Magdalena, MarÃa de Cleofás y MarÃa Salomé. En la escena se encuentran los soldados que acompañaron a Cristo en el camino. En la parte inferior derecha resalta un soldado solo, posiblemente Longinos ya que porta una lanza. A la izquierda varios personajes se muestran conmocionados por lo ocurrido mientras se alejan. https://www.wga.hu/html_m/m/munkacsy/trilog2.htmlActualmente (2019) la obra se conserva en el Déri Múzeum en HungrÃ
