ISSN 2153 733X BARCODING THE ASTERACEAE OF TENNESSEE, TRIBE COREOPSIDEAE EDWARD E. SCHILLING, NICHOLAS MATTSON, AARON FLODEN Herbarium TENN Department of Ecology & Evolutionary Biology University of Tennessee Knoxville, Tennessee 37996 [email protected]; [email protected] ABSTRACT Results from barcoding studies of tribe Coreopsideae for the Tennessee flora using the nuclear ribosomal ITS marker are presented and include the first complete reports for 2 of the 20 species of the tribe that occur in the state, as well as updated reports for several others. Sequence data from the ITS region separate most of the species of Bidens in Tennessee from one another, but species of Coreopsis, especially those of sect. Coreopsis, have ITS sequences that are identical (or nearly so) to at least one congener. Comparisons of sequence data to GenBank records are complicated by apparent inaccuracies of older sequences as well as potentially misidentified samples. Broad survey of C. lanceolata from across its range showed little variability, but the ITS sequence of a morphologically distinct sample from a Florida limestone glade area was distinct in lacking a length polymorphism that was present in other samples. Tribe Coreopsideae is part of the Heliantheae alliance and earlier was often included in an expanded Heliantheae (Anderberg et al. 2007) in which it was usually treated as a subtribe (Crawford et al. 2009). The tribe shows a small burst of diversity in the southeastern USA involving Bidens and Coreopsis sect. -

Sfblake and Tithonia Diversifolia
Prospective agents for the biological control of Tithonia rotundifolia (Mill.) S.F.Blake and Tithonia diversifolia (Hemsl.) A.Gray (Asteraceae) in South Africa D.O. Simelane1*, K.V. Mawela1 & A. Fourie2 1Agricultural Research Council-Plant Protection Research Institute, Private Bag X134, Queenswood, 0121 South Africa 2Agricultural Research Council-Plant Protection Research Institute, Private Bag X5017 Stellenbosch, 7599 South Africa Starting in 2007, two weedy sunflower species, Tithonia rotundifolia (Mill.) S.F.Blake and Tithonia diversifolia (Hemsl.) A.Gray (Asteraceae: Heliantheae), were targeted for biological control in South Africa. Surveys conducted in their native range (Mexico) revealed that there were five potential biological control agents for T.rotundifolia, and three of these are currently undergoing host-specificity and performance evaluations in South Africa. Two leaf-feeding beetles, Zygogramma signatipennis (Stål) and Zygogramma piceicollis (Stål) (Coleoptera: Chrysomelidae), are the most promising biological control agents for T. rotundifolia: prelimi- nary host-specificity trials suggest that they are adequately host-specific. The stem-boring beetle, Lixus fimbriolatus Boheman (Coleoptera: Curculionidae), is also highly damaging to T. rotundifolia, but its host range is yet to be determined. Two other stem-boring beetles, Canidia mexicana Thomson (Coleoptera: Cerambycidae) and Rhodobaenus auctus Chevrolat (Coleoptera: Curculionidae), have also been recorded on T. rotundifolia, and these will be considered for further testing if L. fimbriolatus is found to be unsuitable for release in South Africa. Only two insect species were imported as candidate agents on T. diversifolia, the leaf-feeding butterfly Chlosyne sp. (Lepidoptera: Nymphalidae), and an unidentified stem-boring moth (Lepidoptera: Tortricidae): the latter was tested in quarantine but rejected because it attacked several sunflower cultivars. -
Involvement of Allelopathy in the Invasive Potential of Tithonia Diversifolia
plants Review Involvement of Allelopathy in the Invasive Potential of Tithonia diversifolia Hisashi Kato-Noguchi Department of Applied Biological Science, Faculty of Agriculture, Kagawa University, Miki, Kagawa 761-0795, Japan; [email protected]; Tel.: +81-87-891-3086 Received: 26 May 2020; Accepted: 17 June 2020; Published: 19 June 2020 Abstract: Tithonia diversifolia (Hemsl.) A. Gray (Asteraceae) is native to Mexico and Central America. The species is spreading quickly and has naturalized in more than 70 countries. It has often been recorded as a harmful invasive plant that disturbs native plant communities. Phytotoxic chemical interactions such as allelopathy between invasive plants and native plants have been reported to play an important role in the invasion. Evidence for allelopathy of T. diversifolia has accumulated in the literature over 30 years. Thus, the objective of this review was to discuss the possible involvement of allelopathy in the invasive potential of T. diversifolia. The extracts, root exudates, and plant residues of T. diversifolia inhibited the germination and growth of other plant species. The soil water and soil collected from T. diversifolia fields also showed inhibitory growth effects. The decomposition rate of T. diversifolia residues in soil was reported to be high. Phytotoxic substances such as sesquiterpene lactones were isolated and identified in the extracts of T. diversifolia. Some phytotoxic substances in T. diversifolia may be released into the soil through the decomposition of the plant residues and the exudation from living tissues of T. diversifolia, including its root exudates, which act as allelopathic substances. Those allelopathic substances can inhibit the germination and growth of neighboring plants and may enhance the competitive ability of the plants, make them invasive. -

1148 3rd Myanmar Korea Conference Research Journal Volume 3, No. 3 Morphological, Microscopical Characters and Phytochemical tests of Tithonia diversifolia (Hemsl.) A. Grays Yin Yin Khaing1, Myat Myat Moe2, Sann Sann Oo3 Abstract It is a flowering plant known as Tithonia diversifolia (Hemsl.) A. Grays, belonging to the family Asteraceae. These plants wildly found in Loikaw Township were collected and identified. The morphological characters of vegetative and reproductive parts and microscopical characters of leaves were also studied. Morphology and microscopic examination of these plants were conducted to their correct identification. The plant was perennial robust shrubs and sparsely pubescent. Inflorescences were terminal, solitary head and involucre bracts presented. For microscopical studies, lamina, midrib and petiole were examined by preparing free hand sections. The epidermal cells of both surfaces of the lamina were slightly wavy. Stomata present on both surfaces were numerous and anomocytic type. The preliminary phytochemical tests were examined from the powdered inflorescences. Flavonoid, phenolic compound, tannin, saponin, amino acid and steroid were present in this examination. Introduction Medicinal plants are widely used in non-industrialized societies mainly because they are readily available and cheaper than modern medicine. In many countries, there is little regulation of traditional medicine but world health organization coordinates a network to encourage safe and rational usage. Medicinal plants face both general threats such as climate change and habitat destruction and the specific threat of over collection to meet market demand. Medicinal plants are important for pharmacological research and drug development not only when plant constituents are used directly as therapeutic agents but also when they are used as starting materials for the partial synthesis of drugs or as model for pharmacologically active compounds (WHO, 1998). -

Smithsonian Contri- butions to Botany, number 52, 28 pages, 3 tables, 1981.-Chromosome reports are provided for 145 populations, including first reports for 33 species and three genera, Garcilassa, Riencourtia, and Helianthopsis. Chromosome numbers are arranged according to Robinson’s recently broadened concept of the Heliantheae, with citations for 212 of the ca. 265 genera and 32 of the 35 subtribes. Diverse elements, including the Ambrosieae, typical Heliantheae, most Helenieae, the Tegeteae, and genera such as Arnica from the Senecioneae, are seen to share a specialized cytological history involving polyploid ancestry. The authors disagree with one another regarding the point at which such polyploidy occurred and on whether subtribes lacking higher numbers, such as the Galinsoginae, share the polyploid ancestry. Numerous examples of aneuploid decrease, secondary polyploidy, and some secondary aneuploid decreases are cited. The Marshalliinae are considered remote from other subtribes and close to the Inuleae. Evidence from related tribes favors an ultimate base of X = 10 for the Heliantheae and at least the subfamily As teroideae.

Current address: 8920 South Bryerly Ct., Hereford, AZ 85615, U.S.A. ABSTRACT This article presents both ethnoentomological notes on Nahuatl and Mixtec language terms as they are applied to Cerambycidae (Coleoptera) and distributional records for species collected during three projects carried out in the states of Guerrero and Puebla, Mexico. Some comparative data from other Mesoamerican and Native American languages are discussed. Indigenous common names are mapped onto current taxonomic nomenclature, and an analysis is offered of the logical basis for Indigenous classification: the exclusion of some cerambycids and the inclusion of other beetles in the nominal native “cerambycid” category. New state distributional records for the Cerambycidae collected in this study are offered for Guerrero: Bebelis picta Pascoe, Callipogon senex Dupont, Neocompsa macrotricha Martins, Olenosus ser- rimanus Bates, Ornithia mexicana zapotensis Tippmann, Stenygra histrio Audinet-Serville, Strongylaspis championi Bates, Lissonotus flavocinctus puncticollis Bates, and Nothopleurus lobigenis Bates; and Puebla: Juiaparus mexicanus (Thomson), Ptychodes guttulatus Dillon and Dillon, and Steirastoma senex White.

Mexican Sunflower, Tithonia Rotundifolia
A Horticulture Information article from the Wisconsin Master Gardener website, posted 6 Aug 2018 Mexican sunfl ower, Tithonia rotundifolia The genus Tithonia in the daisy family (Asteraceae) includes 10-15 species of bushy annuals, perennials and shrubs native to Mexico and Central America that have large, brightly colored daisy-like fl owers on thick stems. Mexican sunfl ower, T. rotundifolia, is a vigorous, drought tolerant warm season annual that is easy to grow in the ornamental garden with other common names of red sunfl ower of just tithonia. Tithonia plants grow 4-6+ feet tall, with a large central stalk and a somewhat gangly branching habit. The stems can be brittle. The dark green leaves are ovate to deltoid (triangular) in shape, with serrate to crenate margins. The coarse leaves are usually entire but occasionally will be three lobed. Mexican sunfl ower, Tithonia rotundifolia, is a tall plant. The foliage and stems are covered with a soft downy fuzz, and the underside of The foliage of Mexican sunfl ower is coarse and hairy (L); the ovoid to deltoid the leaves are hairy. leaves have serrate margins and are usually entire (C) but may be three lobed (R). Flowers are produced from mid-summer until frost. The solitary fl owers are borne on fragile hollow peduncles (fl ower stems) that are susceptible to being bent and are often broken by birds. Each 3-inch blossom has a number of bright red to orange ray fl owers surrounding the central yellow disk fl owers. Thick, fuzzy buds (L) open (LC) to reveal bright red to orange ray fl owers (C) surrounding yellow disk fl owers (RC) that remain for a while after the ray fl owers fall off (R).
