Palabras clave: Romulea bulbocodium; corología; pinares de Aznalcázar; bosque-isla; SO ibérico. Rediscovery of Romulea bulbocodium in the province of Seville Abstract. The presence of Romulea bulbocodium (L.) Sebast. & Mauri is confirmed in the province of Seville, where it had not been reported since 1861. Geophyte of circunmediterranean distribution, it is versatile in habitat occupancy and widespread in the Iberian Peninsula. It was considered absent of the territory of Seville, where it still considered as a very rare species. It coexists with Romulea ramiflora Ten. subsp. ramiflora.

Cały obszar jest pokryty poziomo zalegającymi osadami kredy i jury oraz trzeciorzędu i plejstocenu. W wielu miejscach uformowały się pokrywy andezytowo-bazaltowe, a głęboko zalegają skały krystaliczne. Gleby w Izraelu są słabo wykształcone, skaliste (lentosole) i piaszczyste (arenosole). Na południu przeważają gleby brunatne (kambiso- le), a na północy z dużą zawartością nie scementowanych węglanów (kalcisole). W części najbardziej południowej występują sołońce i sołonczaki. Rozciągłość południkowa i urozmaicone ukształtowanie terenu Izraela wpływają na zróżnicowanie typów klimatu. Na północnym zachodzie występuje klimat podzwrotni- kowy typu śródziemnomorskiego, a na południu i wschodzie zwrotnikowy i suchy. Na południu opady czasami nie przekraczają 25 mm rocznie (Arawa), a na północy średnie opady roczne sięgają nawet 1100 mm (Góry Galilejskie). Deszcz pada od października do kwietnia. Lata są gorące i suche, na wybrzeżu złagodzone występowaniem bryzy morskiej.

    Zurich Open Repository and Archive University of Zurich Main Library Strickhofstrasse 39 CH-8057 Zurich www.zora.uzh.ch Year: 2021 Biogeography of the monocotyledon astelioid clade (Asparagales): A history of long-distance dispersal and diversification with emerging habitats Birch, Joanne L ; Kocyan, Alexander Abstract: The astelioid families (Asteliaceae, Blandfordiaceae, Boryaceae, Hypoxidaceae, and Lanari- aceae) have centers of diversity in Australasia and temperate Africa, with secondary centers of diversity in Afromontane Africa, Asia, and Pacific Islands. The global distribution of these families makes this an excellent lineage to test if current distribution patterns are the result of vicariance or long-distance dispersal and to evaluate the roles of tertiary climatic and geological drivers in lineage diversification. Sequence data were generated from five chloroplast regions (petL-psbE, rbcL, rps16-trnK, trnL-trnLF, trnS-trnSG) for 104 ingroup species sampled across global diversity. The astelioid phylogeny was inferred using maximum parsimony, maximum likelihood, and Bayesian inference methods. Divergence dates were estimated with a relaxed clock applied in BEAST. Ancestral ranges were reconstructed in ’BioGeoBEARS’ applying the corrected Akaike information criterion to test for the best-fit biogeographic model. Diver- sification rates were estimated in Bayesian Analysis of Macroevolutionary Mixtures [BAMM]. Astelioid relationships were inferred as Boryaceae(Blandfordiaceae(Asteliaceae(Hypoxidaceae plus Lanariaceae))). The crown astelioid node was dated to the Late Cretaceous (75.2 million years; 95% highest posterior densities interval 61.0-90.0 million years) with an inferred Eastern Gondwanan origin. However, aste- lioid speciation events have not been shaped by Gondwanan vicariance. Rather long-distance dispersal since the Eocene is inferred to account for current distributions.

    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.

Medit. 29: 163-180. 2019. — ISSN: 1120-4052 printed, 2240-4538 online. In the last decades, with the increase of molecular studies, the study of plant forms has gone through a steady decline in interest, and researches on this topic are often neglected and under- estimated. Notwithstanding, comparative morphology as integrative discipline still assumes a pivotal role in modern sciences, remaining fundamentally relevant to nearly all fields of plant biology, such as systematics, evolutionary biology, ecology, physiology, genetics, molecular biology, not to mention also agriculture, bioengineering, and forensic botany. Contrary to com- mon belief, plant morphology is not a conservative finished science, but, like other sciences, it is open to constant innovations involving both concepts and methods. This contribution aims to promote a reflective discourse on the role of plant morphology in modern sciences and provides some examples of significant supports from plant morphology to different botanical issues. Key words: Systematics, plant micromorphology, seed coat sculpturing, leaf anatomy, ecomor- phology, climate adaptation. Introduction Despite the increasing societal awareness and sensitivity about the knowledge of bio- logical diversity and ecosystem functioning as pivotal matters for nature conservation on which human health and well-being fundamentally depend, studies in morphology-based classical taxonomy have increasingly become marginalized and considered less significant than other scientific methods in plant biology.

Silver nanoparticles were green synthesized from one mmol×l-1 silver nitrate extract of C. mathewii. The water-suspended silver nanoparticles showed a peak at 423 nm in UV/Vis spectrophotometer that suggested smaller particle size due to its less surface plasmon resonance. Transmission electron microscopy analysis also proved excellent polydispersity of quasi-spherical particle size distribution with average particles of 7.5 nm (2.5-25 nm). The presence of silver in the nanoparticles was analyzed by X-ray diffraction, while Fourier transform infrared spectroscopy analysis showed the presence of various –OH and –NH containing organics. The results proved that the crude extract of C. mathewii can be used for green synthesis of silver nanoparticles in future for medicinal uses. Key words: Silver nanoparticles, Crocus mathewii, endemic plant, TEM, XRD Crocus belongs to subfamily Crocoideae of Iridaceae, Careful literature survey reflected that researchers a family of around 80 genera and almost 1500 have totally ignored this plant. There is no report species[1,2]. Crocus is a genus of 90 flowering species on the phytochemistry or any other scientific that are grown from the corm[3]; most of the species are study on C.

    Review of the Genus Xenoscapa (Iridaceae: Crocoideae), Including X. Grandiflora, a New Species from Southern Namibia

    Bothalia 41,2: 283–288 (2011) Review of the genus Xenoscapa (Iridaceae: Crocoideae), including X. grandiflora, a new species from southern Namibia J.C. MANNING* and P. GOLDBLATT** Keywords: Iridaceae, new species, southern Africa, taxonomy, Xenoscapa (Goldblatt) Goldblatt & J.C.Manning ABSTRACT The small genus Xenoscapa (Goldblatt) Goldblatt & J.C.Manning, endemic to the southern African winter rainfall region, is reviewed. The new species X. grandiflora is described from the deeply dissected southern part of the Huib Hoch Plateau in southern Namibia. It differs from the two known species in the genus in its significantly larger, pale lilac flowers. Full descriptions and accounts of all three known species are provided, with distribution maps and illustrations. INTRODUCTION The two known species of Xenoscapa are distin- guished by small differences in perianth size and colour, Xenoscapa (Goldblatt) Goldblatt & J.C.Manning, one of height of the flowering stems in fruit, and the presence the smallest genera in Iridaceae, currently comprises two or absence of floral fragrance (Table 1). X. fistulosa is species from the winter rainfall region of southern Namibia relatively widespread, occurring throughout the range and southwestern South Africa. Both are small, deciduous of the genus, from the Huib Hoch Plateau in southern geophytes with two or three, soft-textured, prostrate foli- Nambia southwards along the Namaqualand escarpment age leaves and unusual, single-flowered, mostly shortly and the interior mountains of the southwestern Cape, branched spikes (Goldblatt & Manning 1995, 2008). The with two outlying populations along the West Coast vegetative similarity between them extends to the flowers, (Goldblatt & Manning 2000a). X.
