Offa, Kwara State, Nigeria Email: [email protected] ABSTRACT: Chlorophytum Ker-Gawl. is a monocotyledonous perennial herb. Its perennating organ is rhizome which may be tuberous or not. The genus like other Liliales is characterized by having tricarpellay syncarpous ovary. In the present study, samples of the species collected from the North Central part of Nigeria and used for this study, were observed to have multiple carpels fused at the base and with free styles. This is the main diagnostic feature of the newly identified species. Multicarpellary syncarpous ovary is not only new for the genus but also for the tribe Asphodeleae of Hutchinson's system. The carpels consist of; 3 with long free styles and 3 with short free styles. Placentation is axile, with three chambers, suggesting carpellode situation in few of its carpels. The new taxon is therefore named Chlorophytum sabiense. Omokanye, sp. nov. TYPE: Nigeria, Sabi DOI: https://dx.doi.org/10.4314/jasem.v24i12.14 Copyright: Copyright © 2020 Omokanye.

A thesis presented in partial fulfillment of the requirements for the degree of Master of Science in Biological Sciences Massey University Palmerston North, New Zealand Simon James Lethbridge Cox 2010 Abstract This thesis describes the application of high throughput (Illumina) short read sequencing and analyses to obtain the chloroplast genome sequence of Arthropodium bifurcatum and chloroplast genome markers for future testing of hypotheses that explain geographic distributions of Rengarenga – the name Maori give to species of Arthropodium in New Zealand. It has been proposed that A.cirratum was translocated from regions in the north of New Zealand to zones further south due to its value as a food crop. In order to develop markers to test this hypothesis, the chloroplast genome of the closely related A.bifurcatum was sequenced and annotated. A range of tools were used to handle the large quantities of data produced by the Illumina GAIIx. Programs included the de novo assembler Velvet, alignment tools BWA and Bowtie, the viewer Tablet and the quality control program SolexaQA. The A.bifurcatum genome was then used as a reference to align long range PCR products amplified from multiple accessions of A.cirratum and A.bifurcatum sampled from a range of geographic locations. From this alignment variable SNP markers were identified.

  • Comparative Population Dynamics of Two Closely Related Species Differing in Ploidy Level
    Comparative Population Dynamics of Two Closely Related Species Differing in Ploidy Level Lucie Cˇ erna´ 1, Zuzana Mu¨ nzbergova´ 1,2* 1 Department of Botany, Faculty of Science, Charles University, Prague, Czech Republic, 2 Institute of Botany, Academy of Sciences, Pru˚honice, Czech Republic Abstract Background: Many studies compare the population dynamics of single species within multiple habitat types, while much less is known about the differences in population dynamics in closely related species in the same habitat. Additionally, comparisons of the effect of habitat types and species are largely missing. Methodology and Principal Findings: We estimated the importance of the habitat type and species for population dynamics of plants. Specifically, we compared the dynamics of two closely related species, the allotetraploid species Anthericum liliago and the diploid species Anthericum ramosum, occurring in the same habitat type. We also compared the dynamics of A. ramosum in two contrasting habitats. We examined three populations per species and habitat type. The results showed that single life history traits as well as the mean population dynamics of A. liliago and A. ramosum from the same habitat type were more similar than the population dynamics of A. ramosum from the two contrasting habitats. Conclusions: Our findings suggest that when transferring knowledge regarding population dynamics between populations, we need to take habitat conditions into account, as these conditions appear to be more important than the species involved (ploidy level). However, the two species differ significantly in their overall population growth rates, indicating that the ploidy level has an effect on species performance. In contrast to what has been suggested by previous studies, we observed a higher population growth rate in the diploid species.

  • Networks in a Large-Scale Phylogenetic Analysis: Reconstructing Evolutionary History of Asparagales (Lilianae) Based on Four Plastid Genes
    Networks in a Large-Scale Phylogenetic Analysis: Reconstructing Evolutionary History of Asparagales (Lilianae) Based on Four Plastid Genes Shichao Chen1., Dong-Kap Kim2., Mark W. Chase3, Joo-Hwan Kim4* 1 College of Life Science and Technology, Tongji University, Shanghai, China, 2 Division of Forest Resource Conservation, Korea National Arboretum, Pocheon, Gyeonggi- do, Korea, 3 Jodrell Laboratory, Royal Botanic Gardens, Kew, Richmond, United Kingdom, 4 Department of Life Science, Gachon University, Seongnam, Gyeonggi-do, Korea Abstract Phylogenetic analysis aims to produce a bifurcating tree, which disregards conflicting signals and displays only those that are present in a large proportion of the data. However, any character (or tree) conflict in a dataset allows the exploration of support for various evolutionary hypotheses. Although data-display network approaches exist, biologists cannot easily and routinely use them to compute rooted phylogenetic networks on real datasets containing hundreds of taxa. Here, we constructed an original neighbour-net for a large dataset of Asparagales to highlight the aspects of the resulting network that will be important for interpreting phylogeny. The analyses were largely conducted with new data collected for the same loci as in previous studies, but from different species accessions and greater sampling in many cases than in published analyses. The network tree summarised the majority data pattern in the characters of plastid sequences before tree building, which largely confirmed the currently recognised phylogenetic relationships. Most conflicting signals are at the base of each group along the Asparagales backbone, which helps us to establish the expectancy and advance our understanding of some difficult taxa relationships and their phylogeny.

It belongs to subgenus Centaurea s. str. (WAGENITZ 1975) which comprises a controversial number of species which inhabit the steppes, forest steppes and mesoxerophytic bushy submediterranean habitats from western Palaearctis. The species is known from only three localities in the entire Transylvania and Romania, which are at the same time the westernmost ones in the range of this species. Here we analyse the three Transylvanian localities of this rare and precious element that needs urgent protective measures. The taxonomic and biogeographic context of the species The place of the subgenus Centaurea s.str. within the genus Centaurea L. and even more largely within the entire tribe of Cardueae was investigated by SUSSANNA – JACAS – SOLTIS - SOLTIS (1995). They have concluded that Centaurea L. can be paraphyletic and that subgenus Centaurea s. str. is a primitive, isolated branch that seems to be more related with other genera like Cheirolophus Cass. Therefore, the unity of the genus should be questioned in the future and a serious revision based upon the phylogenetic relations inferred from genetical, biochemical and morphological studies is further needed.

Jacques Spider Plant (Anthericum comosum, Anthericum mandaianum, Chlorophytum beniense, Chlorophytum capense, Chlorophytum ela- tum, Chlorophytum mandaianum, Chlorophytum picturatum, Chlorophytum semlikiense, Chlorophytum sternbergi- unum, Chlorophytum vittatum) Other Common Names: Airplane Plant, Hen-And-Chickens, Ribbonplant, Spider-Ivy, Spiderplant, Walking Anthe- ricum. Family: Agaveaceae; also placed by some authorities in the Antheriaceae or Liliaceae. Cold Hardiness: While the foliage is killed by even light frosts, plants are root hardy in USDA zones 9 (8b) to 11, and function as an evergreen herbaceous perennial in USDA zones 10 (9b) to 11. 3 Foliage: Alternate, evergreen, glabrous, linear-lanceolate slightly arching 6O to 12O (18O) long by ⁄8O to ¾O wide sword-shaped leaves are keeled at the base; blades have entire to slightly undulate margins with acuminate tips; leaves of most cultivars are streaked with white to creamy yellow variegation, while the species type is green alone. Flower: The small single white flowers are approximately ¾O across with a whorl of three narrowly ovate white petals in an alternating pattern with a subtending whorl of three white lanceolate sepals; a single pistil is sur- rounded by six stamens; the flowers are present year-round and subtly attractive, but are sparsely borne on the 6O to 14O long racemes. Fruit: Tiny triangular deeply lobed three-celled leathery capsules with three to five flat black seeds each follow the flowers singly or in small clusters. Stem / Bark: Stems — vegetative stems are short and stout with very short internodes, while flower stalks are stiff, wiry, and lightly scabrous; viviparous plantlets form on the terminus of these stalks and produce fleshy aerial rootlets; Buds — tiny green buds are largely encased in the rosette at the base of the plant, or elongate shortly after formation on the wiry arching flower stalks; Bark — not applicable.

    Volume 19(2), 176- 189, 2015 JOURNAL of Horticulture, Forestry and Biotechnology www.journal-hfb.usab-tm.ro Research on spontaneous and subspontaneous flora of Botanical Garden "Vasile Fati" Jibou Szatmari P-M*.1,, Căprar M. 1 1) Biological Research Center, Botanical Garden “Vasile Fati” Jibou, Wesselényi Miklós Street, No. 16, 455200 Jibou, Romania; *Corresponding author. Email: [email protected] Abstract The research presented in this paper had the purpose of Key words inventory and knowledge of spontaneous and subspontaneous plant species of Botanical Garden "Vasile Fati" Jibou, Salaj, Romania. Following systematic Jibou Botanical Garden, investigations undertaken in the botanical garden a large number of spontaneous flora, spontaneous taxons were found from the Romanian flora (650 species of adventive and vascular plants and 20 species of moss). Also were inventoried 38 species of subspontaneous plants, adventive plants, permanently established in Romania and 176 vascular plant floristic analysis, Romania species that have migrated from culture and multiply by themselves throughout the garden. In the garden greenhouses were found 183 subspontaneous species and weeds, both from the Romanian flora as well as tropical plants introduced by accident. Thus the total number of wild species rises to 1055, a large number compared to the occupied area. Some rare spontaneous plants and endemic to the Romanian flora (Galium abaujense, Cephalaria radiata, Crocus banaticus) were found. Cultivated species that once migrated from culture, accommodated to environmental conditions and conquered new territories; standing out is the Cyrtomium falcatum fern, once escaped from the greenhouses it continues to develop on their outer walls. Jibou Botanical Garden is the second largest exotic species can adapt and breed further without any botanical garden in Romania, after "Anastasie Fătu" care [11].

Email: [email protected] Abstract Sister group relations of Ethiopian species of Anthericum and Chlorophytum and variation patterns in the C. gallabatense and C. comosum complexes were studied using molecular phylogenetic analyses, morphometrics, and scanning electron microscopy of seed surfaces. Results indicate that molecular data largely support previous morphological conclusions, and that speciation has occurred in Ethiopia at least three times in Anthericum and repeatedly within different subclades of Chlorophytum. Areas particularly rich in endemic species are the lowland area around Bale Mountains in SE Ethiopia and in the Beninshangul Gumuz regional state in W Ethiopia near the border to Sudan.
