Barcoding the Asteraceae of Tennessee, Tribe Coreopsideae
Schilling, E.E., N. Mattson, and A. Floden. 2014. Barcoding the Asteraceae of Tennessee, tribe Coreopsideae. Phytoneuron 2014-101: 1–6. Published 20 October 2014. 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. -
Chromosome Numbers in Compositae, XII: Heliantheae
SMITHSONIAN CONTRIBUTIONS TO BOTANY 0 NCTMBER 52 Chromosome Numbers in Compositae, XII: Heliantheae Harold Robinson, A. Michael Powell, Robert M. King, andJames F. Weedin SMITHSONIAN INSTITUTION PRESS City of Washington 1981 ABSTRACT Robinson, Harold, A. Michael Powell, Robert M. King, and James F. Weedin. Chromosome Numbers in Compositae, XII: Heliantheae. 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.

It is believed to have originated in South America soon after the appearance of the Family and may be regarded as the oldest and most primitive of the tribes. The near approach to the earliest composite form is said to be retained in the more foliaceous outer invol ucral bracts, the more normally developed and more firmly attached paleae subtending the disk flowers, the 0 less transformed calyx-limb of persistent teeth or aristae directly continuous with the ribs of the ovary, and in some genera, the less firmly united or nearly free anthers.
