Gladiolus mariae (Iridaceae), a new species from fire-free shrubland in the Kounounkan Massif, Guinea
Gladiolus mariae Burgt (Iridaceae), a new species from Guinea, West Africa, is described and illustrated. The new species is placed in Gladiolus sect. Decorati Goldblatt and compared with the nine species already known from that section. Flowering plants stand 28–160 cm high with 1–6 bright orange flowers, opening one at...van de Burgt, Xander ; Konomou, Gbamon ; Haba, Pepe ; Magassouba, Sékou

Genetic diversity and origin of the rare, narrow endemic Asperula crassifolia (Rubiaceae)
We examined the patterns of genetic variation in the narrow endemic Asperula crassifolia (Campania, southern Italy), taking into account the schizoendemic distribution of the Mediterranean members of Asperula sect. Cynanchicae. We obtained plastid DNA sequences of the rps16 intron and the trnC-petN intergenic spacer for several members of A. sect....Gargiulo, Roberta ; De Castro, O ; Del Guacchio, E ; Caputo, P

From plant fungi to bee parasites: mycorrhizae and soil nutrients shape floral chemistry and bee pathogens
Bee populations have experienced declines in recent years, due in part to increased disease incidence. Multiple factors influence bee-pathogen interactions, including nectar and pollen quality and secondary metabolites. However, we lack an understanding of how plant interactions with their environment shape bee diet quality. We examined how plant interactions with... -

Galanthus bursanus (Amaryllidaceae): a new species of snowdrop from the Marmara Sea region, NW Turkey
Galanthus bursanus (Amaryllidaceae), a new snowdrop species endemic to the Marmara Sea region (Bursa Province, NW Turkey), is described and illustrated. Morphological differences between the new species and other possibly related Galanthus taxa (G. plicatus subsp. byzantinus, G. ×valentinei nothosubsp. subplicatus, and G. reginae-olgae subsp. reginae-olgae) are discussed. Photographs (habitat...Zubov, Dimitri ; Konca, Yıldiz ; Davis, Aaron

Flora of Singapore precursors, 6: Typification of grass names relevant to the flora of Singapore
The typification of more than 200 names of grass taxa relevant to the flora of Singapore is reviewed. A total of 52 lectotype designations are made here, including 22 which are posthumously published by the late J.F. Veldkamp. In addition, 13 second-step lectotypes (one by JFV), and two neotypes are...Turner, I ; Middleton, D ; Duistermaat, H ; Veldkamp, J

Five new species of Henckelia (Gesneriaceae) from Myanmar and Thailand.
Five new species of Henckelia are described, two from Myanmar: Henckelia campanuliflora and H. candida, and the others from Thailand: H. amplexifolia, H. nakianensis and H. dasycalyx. A key to the 1 to 2-leaved species of the genus is given, as well as photographs, ecology, and also IUCN conservation status...Sirimongkol, Sukontip ; Parnell, John ; Hodkinson, Trevor ; Middleton, David ; Puglisi, Carmen

Farmers’ decisions and determinants of crop rotations with lupin (Lupinus spp): The case of West Amhara Region, Ethiopia
Using lupin as a break crop and for soil fertility improvement is one of the practices to enhance productivity and improve soil fertility in Ethiopian conditions. However, the use of this practice by smallholder farmers is limited. Therefore, the major objective of this study was to empirically examine factors influencing...Teferra, B ; Yeheyis, L ; Nelson, M ; Taylor, J ; McNaughton, D …

Evolutionary history of the Pasque-flowers (Pulsatilla, Ranunculaceae): Molecular phylogenetics, systematics and rDNA evolution
Pulsatilla (Anemoneae, Ranunculaceae) is sister to Anemone s.s. and contains ca 40 perennial species of considerable horticultural and medical importance. We sequenced 31 of those species, plus nine subspecies, two cultivars and six outgroups, for two nuclear regions (high-copy nrITS and low-copy MLH1) and three plastid regions (rbcL, accD–psaI, trnL...Sramkó, G ; Laczkó, L ; Volkova, P ; Bateman, R ; Mlinarec, J
