Notes on the Occurrence of Erigeron Sumatrensis (Asteraceae) in Georgia
Nesom, G.L. 2018. Notes on the occurrence of Erigeron sumatrensis (Asteraceae) in Georgia. Phytoneuron 2018-66: 1–5. Published 1 October 2018. ISSN 2153 733X NOTES ON THE OCCURRENCE OF ERIGERON SUMATRENSIS (ASTERACEAE) IN GEORGIA GUY L. NESOM 2925 Hartwood Drive Fort Worth, Texas 76109 [email protected] ABSTRACT A survey for Erigeron sumatrensis in central Georgia indicates that it is densely distributed on the the coastal plain there, suggesting that its occurrence may be similar from South Carolina to Louisiana. Vouchers and a distribution map for the Georgia records are provided. A recent study (Nesom 2018) documented the occurrence of Erigeron sumatrensis Retz. across the southeastern USA (Fig. 1). Current herbarium collections suggest that it is common in coastal counties but sporadic in more inland areas. The present report indicates that the species probably is more densely distributed through the coastal plain from South Carolina to Louisiana. On 9-10 September, 2018, I surveyed a broad loop in central Georgia and added 14 county records to the distribution of Erigeron sumatrensis . Figure 2 shows the more geographically saturated distribution the species has attained there. The tall columnar habit (characteristically 4-6 feet tall) of Erigeron sumatrensis makes it conspicuous (Figs. 3-5). In central Georgia I found it along roadsides and fencerows and at edges of cultivated and fallow fields. It is local in occurrence, usually as only 1 or a few plants (but sometimes up to 10-15 in a cluster), often growing with more abundant and continuously distributed E. canadensis . Erigeron sumatrensis in September is at the end of its growing season and mostly in fruit, while many plants of E.

(Asteraceae) species from Turkey Faruk Karahan* Department of Biology, Faculty of Science and Arts, Hatay Mustafa Kemal University, 31040 Hatay, Turkey Abstract – In the present study, the morphological characters, root, stem and leaf anatomy, pollen and achene micromorphology of Bellis L. species (Bellis annua L., B. perennis L. and B. sylvestris Cirillo) distributed in Turkey have been investigated on light and scanning electron microscope. Palynological analysis showed that pollen characters were found as small to medium size, isopolar, radially symmetrical, oblate-spheroidal and prolate- spheroidal, tricolporate and echinate-perforate ornamentation in the three species. Achene characters were found dark brown to yellow in colour, often cylindrical, compressed, with thickened margin, obovate orobovoid shaped, pappus absent and the coat ornamentations are rectangular with short hairs on the surface. As a result of this study, leaf morphology and some pollen characteristics such as pollen size, shape, perforation and distance be- tween spines were demonstrated to be different among the Bellis species. Keywords: Bellis, common daisy, Compositae, taxonomy, SEM Introduction The genus Bellis L. (Asteraceae) has been included in the Fiz et al.

K. Čiurlionio 21, Vilnius, Lithuania 2Botanical Garden of Vilnius University, Kairėnų 43, Vilnius, Lithuania *Corresponding author, [email protected] DOI 10.5073/jka.2014.443.023 Abstract This study was conducted to assess the clonal structure and genetic diversity of alien herbaceous plant species Erigeron annuus. The global warming and changes in agriculture practice in the past few decades were favourable for the expansion of this species in Lithuania. We used RAPD and ISSR assays to assess genetic variation within and among 29 populations of E. annuus. A total of 278 molecular markers were revealed. Our study detected reduced level of genetic diversity of invasive populations of E. annuus. Significant differences in DNA polymorphism among populations of E. annuus were also found. Some populations of this species are composed of genetically identical plants, while others were polymorphic. Clonal diversity of study populations ranged from 0.083 to 0.4 for both DNA marker systems. The Simpsons diversity index values ranged from 0.0 to 0.636. The average number of genotypes per population established using both assays was about 1.7. Out of 328 E. annuus individuals only 16 showed unique RAPD and 14 unique ISSR banding patterns. The remaining plants were clones of different size.

Abstract: is eld guide is a tool for the identication of 119 common forbs found in the sagebrush rangelands and grasslands of the northern Great Basin. ese forbs are important because they are either browsed directly by Greater Sage-grouse or support invertebrates that are also consumed by the birds. Species are arranged alphabetically by genus and species within families. Each species has a botanical description and one or more color photographs to assist the user. Most descriptions mention the importance of the plant and how it is used by Greater Sage-grouse. A glossary and indices with common and scientic names are provided to facilitate use of the guide. is guide is not intended to be either an inclusive list of species found in the northern Great Basin or a list of species used by Greater Sage-grouse; some other important genera are presented in an appendix.

Pers. (daisy fleabane) in Republic of Macedonia Accepted 27th August, 2015 ABSTRACT Detail survey of population of Erigeron annuus (L.) Pers., an invasive plant species native to eastern North America, were made in three border locations in north- western, northern and eastern parts of the Republic of Macedonia. The surveys revealed an intensive growth and different dense population of E. annuus. The population density was not quantified, but several stands of different sizes were found. A rapid ecological risk assessment, mainly based on knowledge about invasion histories in South-Eastern and Central European countries, showed that this specie is a serious threat to Macedonian biodiversity, particularly, in the Zvonko Pacanoski1* and Alirami Saliji1 North-western part, where dense stands of E. annuus monoculture were recorded.
