The Genus Ornithogalum (Liliaceae) and Its Karyotype Variation in European Turkey
Giiler Dalglç & Neriman Ozhatay The genus Ornithogalum (Liliaceae) and its karyotype variation in European Turkey Abstract Dalglç, G. & Ozhatay, N.: The genus Omithogalum (Liliaceae) and its karyotype variation in European Turkey. - Bocconea 5: 743-747.1997. - ISSN 1120-4060. Omithogalum is currently represented in European Turkey by 13 species. Chromosome num bers, counted on all, are tabulated, and micrographs of somatic metaphase plates are provided. Introduction Ornithogalum is a taxonomically difficult genus, in which c1ear-cut limits between taxa are exceptional, while morphology is poorly correlated with variation in chromosome number and karyotype. According to the Flora ofTurkey (Davis 1984, 1988), the genus is represented in Turkey by 27 species, to which recent publications (Speta 1989, 1990, 1991a-e, 1992, Johnson & al. 1991) have added 15 more. In European Turkey, 13 Orni thogalum species have so far been found, which are grouped into 3 subgenera, as folIows: o. subg. Beryllis (O. pyrenaicum, O. brevistylum); o. subg. Ornithogalum (O. armenia cum, o. orthophyllum, o. comosum, O. fimbriatum, O. montanum, O. oligophyllum, O. sibthorpii, O. refractum, o. umbellatum); and o. subg. Myogalum (O. nutans, O. boucheanum). Material and methods AlI 13 Ornithogalum species occurring in European Turkey have been studied cyto- 10gicalIy. The plant materiaI (see Table l) consisted of bulbs collected from the wiId and cultivated in greenhouses or out of doors in the experimental garden at the Departments of Botany in Edirne and/or Istanbul. Root tips were pre-treated in saturated aqueous alpha-bromonaphthalene for 24 hours at 5-6°C and fixed in 3 : l aIcohoI: acetic acido Chrornosome preparations were made using a standard Feulgen-stain squash technique (Johnson & al.

Vascular Plants of a Delaware River Tidal Freshwater
Journal of the Torrey Botanical Society 132(2), 2005, pp. 323–354 Vascular plants of a Delaware River tidal freshwater wetland and adjacent terrestrial areas: Seed bank and vegetation comparisons of reference and constructed marshes and annotated species list1 Mary Allessio Leck2,3 Biology Department, Rider University, Lawrenceville, NJ 08648 Charles F. Leck Department of Ecology and Evolutionary Biology, Cook College, Rutgers University, New Brunswick, NJ 08901 LECK, M. A. (Dept. Biol., Rider Univ., Lawrenceville, NJ 08648) AND C. F. LECK (Dept. Ecol. & Evol. Biol., Cook College, Rutgers Univ., New Brunswick, NJ 08901). Vascular plants of a Delaware River tidal freshwater wetland and adjacent terrestrial areas: Seed bank and vegetation comparisons of reference and constructed marshes and annotated species list. J. Torrey Bot. Soc. 132: 323–354. 2005.—Constructed wetland soil samples contained many more species with densities Ͼ 100 seeds / m2 than reference marsh ones (102 vs. 28); constructed wetland densities for many species were considerably higher and richness (species / sample) were Ͼ 2ϫ greater than the reference marsh. Of the total 218 seed bank species, 60 were common to both and 34 occurred only in reference marsh samples. Numbers of cover species were similar, but composition differed. Invasive species, notably Lythrum salicaria, Phalaris arundinacea, and Phragmites australis, were more important in constructed wetland soil samples and vegetation. Non-native species comprised 9 % and 13 % of the reference marsh and constructed wetland seed bank species and 8 % and 12 % of the cover species, respectively. Variable dispersal patterns and in situ seed production contributed to these differences. Over the entire study area (wetlands and adjacent terrestrial areas) we recorded 875 species, representing 141 families, more than doubling the number observed in a 1988 report.

Box 99, E-03080 Alicante, Spain. 3 Selmar Schonland Herbarium, Department of Botany, Rhodes University, Grahamstown 6140, South Africa. *author for correspondence Abstract Hyacinthaceae (Asparagaceae subfam. Scilloideae) are commonly hysteranthous or proteranthous plants, in which leaves and inflorescences usually are not present simultaneously. Consequently, to facilitate future identification, type “specimens” were sometimes prepared to combine fragments gathered at different times so as to include as many vegetative and reproduc- tive structures as possible. However, this is not acceptable under the rules of nomenclature. We here lectotypify four species names of Hyacinthaceae for which the intended types do not conform to the ICN (Melbourne Code). Furthermore, seven new combinations are presented to transfer recently described units of Ornithogaloideae and Urgineoideae to their proper genera, characterized by distinct and consistent morphological syndromes. Key words: Coilonox, Eliokarmos, Fusifilum, Hyacinthaceae, Litanthus, nomenclature, Ornithogalum, Rhadamanthus, Schizobasis, typification, Urginea Introduction Hyacinthaceae sensu APG (2003) include about a thousand species of bulbous plants, distributed mainly through Europe, Africa and Asia, with a single small genus, Oziroë Rafinesque (1837: 53), in South America.

The Genus Ornithogalum L. (Hyacinthaceae) in Italy, XIV: Towards a Redefinition of Infrageneric Taxa, with New Proposals
F. Garbari, A. Giordani, R. Marcucci & N. Tomadore The genus Ornithogalum L. (Hyacinthaceae) in Italy, XIV: towards a redefinition of infrageneric taxa, with new proposals Abstract Garbari. F., Giordani, A., Marcucci R. & Tomadore, N.: The genus Ornithogalum L. (Hyacinthaceae) in Italy, XIV: towards a redefinition of infrageneric taxa, with new proposals. - Bocconea 16(1): 269-281. 2003. - ISSN 1120-4060. In agreement with other authors, Ornithogalum L. is considered as a distinct genus in respect to Honorius S. F. Gray and Loncomelos Raf. Accordingly, the ltalian taxa of Ornithogalum s. str. are here listed and briefly commented in a frame of their classical morphological and kary ological characters. o. umbellalum L. is represented by different polyploid cytotypes ( 2n= 27, 36, 45, 54, 90 and 108, with or without B chromosomes). Doubts about the possibility to dis criminate o. vulgare Sailer in such a variable complex are expressed. o. divergens Boreau (2n=54 + B), o. orthophyllum Ten. (2n=I8), o. exscapum Ten. (2n=I8) and o. ambiguum Terracciano (2n= I8) are probably in relation with o. corsicum Jordan & Fourr. (2n= 18). o. adalgisae Groves (2n=45, 54), o. refractum Kit. (2n=54) and O. brulium Terracciano (2n=36, 45,54 + B, 72) constitute a group ofunits whose affinity and distribution must be further evaI uated. o. kochii ParI. (2n=I8 + B), looks very similar to o. monticolum Jordan. & Foun·. (2n=20). o. collinum Guss. (2n=18), according with our records, is present only in Sicily. o. comosum L. (2n=18), belonging to sect. Obtusangula Zahar., is distributed from north-eastem Italy to Sicily.

Invasive Species of the Month for February 2018
Invasive Species of the Month for February 2018 Star-of-Bethlehem (Ornithogalum umbellatum) Origin: Europe, Northern Africa, and the Middle East Interesting Fact: Star-of-Bethlehem resembles some edible species such as Wild Garlic and other Allium species, but do not eat Star of Bethlehem as it is poisonous. Description: Star-of-Bethlehem is a small perennial herbaceous plant in the Lily Family that grows from bulbs. Star of Bethlehem has small, linear, grass-like leaves and showy, six-petaled white flowers. Defining characteristics: • Small, linear leaves with white midribs • Clusters of white six-petaled flowers that resemble stars • Lots of small bulbs growing closely together • Three-celled seed capsules that develop from the flowers (Left image) The white flowers and leaves with white midrib (Center image) The bulbs of Star-of-Bethlehem and leaves beginning to emerge in early February. (Right image) Patches of Star-of-Bethlehem in the spring (Mark Frey, The Presidio Trust, Bugwood.org) Habitat: Found in moist to wet habitats such as floodplains, riparian areas, mesic woods, disturbed woods, forest edges, gardens and yards. (Right Image) Star-of-Bethlehem invading a woodland edge at Fox Ridge Nature Park. Ecological threat: Star-of-Bethlehem reproduces mainly by new bulb offsets, and it can form dense ground cover and outcompete native plants. Damage to the bulbs does not prevent reproduction either. The waxy foliage of Star-of-Bethlehem can be resistant to several common herbicides, making management of this species quite difficult. In addition, the foliage and leaves are poisonous to livestock and other grazing animals. Control Methods: • Manual: Bulbs can be dug up and disposed of properly; however, some of them can be fairly deep in the ground.
