Lamiales – Synoptical Classification Vers
Lamiales – Synoptical classification vers. 2.6.2 (in prog.) Updated: 12 April, 2016 A Synoptical Classification of the Lamiales Version 2.6.2 (This is a working document) Compiled by Richard Olmstead With the help of: D. Albach, P. Beardsley, D. Bedigian, B. Bremer, P. Cantino, J. Chau, J. L. Clark, B. Drew, P. Garnock- Jones, S. Grose (Heydler), R. Harley, H.-D. Ihlenfeldt, B. Li, L. Lohmann, S. Mathews, L. McDade, K. Müller, E. Norman, N. O’Leary, B. Oxelman, J. Reveal, R. Scotland, J. Smith, D. Tank, E. Tripp, S. Wagstaff, E. Wallander, A. Weber, A. Wolfe, A. Wortley, N. Young, M. Zjhra, and many others [estimated 25 families, 1041 genera, and ca. 21,878 species in Lamiales] The goal of this project is to produce a working infraordinal classification of the Lamiales to genus with information on distribution and species richness. All recognized taxa will be clades; adherence to Linnaean ranks is optional. Synonymy is very incomplete (comprehensive synonymy is not a goal of the project, but could be incorporated). Although I anticipate producing a publishable version of this classification at a future date, my near- term goal is to produce a web-accessible version, which will be available to the public and which will be updated regularly through input from systematists familiar with taxa within the Lamiales. For further information on the project and to provide information for future versions, please contact R. Olmstead via email at [email protected], or by regular mail at: Department of Biology, Box 355325, University of Washington, Seattle WA 98195, USA. -

Pollination and Breeding Systems of Selected Wildflowers in a Southern African Grassland Community ⁎ S.D
Available online at www.sciencedirect.com South African Journal of Botany 75 (2009) 630–645 www.elsevier.com/locate/sajb Pollination and breeding systems of selected wildflowers in a southern African grassland community ⁎ S.D.

However, there has been no attempt to study community-wide patterns in breeding systems or plant–pollinator mutualisms. Here, we present the results of extensive field work on twenty-one wildflower species with large, showy flowers, belonging to a broad range of angiosperm families. Most of the plant species investigated were found to be self-incompatible and therefore completely dependent on pollinators. Based on over 250 h of field observations during which we recorded over 1000 individual insects, 368 of which were examined for pollen loads, we identified pollination systems involving, inter alia, bees and flies (both short- and long-tongued), wasps, butterflies, hawkmoths, beetles, and sunbirds. The most important pollinators of the wildflowers investigated in the community were long-tongued solitary bees. Several plant species appear to be dependent on a single or a few pollinator species, and few are true generalists. This high degree of specialisation indicates a well- structured pollination landscape, suggesting both a history of climatic and ecological stability and potential sensitivity to human disturbance. -

Thirty-nine genera representing 24 tribes of the Scrophulariaceae s.l. (sensu lato) were analyzed along with representatives of 15 other families of Lamiales. The Scrophulariaceae s.s. (sensu stricto) include part or all of tribes Aptosimeae, Hemimerideae, Leucophylleae, Manuleae, Selagineae, and Verbasceae (5 Scrophularieae) and the conventional families Buddlejaceae and Myoporaceae. Veronicaceae includes all or part of tribes Angelonieae, Antirrhineae, Cheloneae, Digitaleae, and Gratioleae and the conventional families Callitrichaceae, Globulariaceae, Hippuridaceae, and Plantaginaceae. The Orobanchaceae include tribes Buchnereae, Rhinantheae, and the conventional Orobanchaceae. All sampled members of Orobanchaceae are parasitic, except Lindenbergia, which is sister to the rest of the family. Family Calceolariaceae Olmstead is newly erected herein to recognize the phylogenetic distinctiveness of tribe Calceolarieae. -

A multitude of studies investigating the evolution of flowering plants have attempted to determine why angiosperms are so diverse. One possible major contributor to flower form diversity is pollinator pressure. The interactions between flowers and their pollinators have important ecological and evolutionary consequences, with co-evolution often occuring. Many studies have looked at suites of floral traits that affect pollinator visitation, which have been coined pollination syndromes (Fenster et al., 2004). These traits include but are not limited to, flower color, flower orientation, landing platforms, and nectar guides. With the increase in genetic tools, and the utilization of model species such as Antirrhinum majus(Plantaginaceae) and Arabidopsis thaliana (Brassicaeae), many studies are looking at the geneitc architecture of floral traits. Studies have determined the genetic blueprint for floral oragn identity, as well as in traits asociated with pollination syndromes including flower color and symmetry. -

University ABSTRACT Jamesbrittenia is a genus of 84 largely perennial sub-shrubs and herbs with a wide distribution in southern Africa (except J. dissecta in Sudan, Egypt and India). Plastid (rps16 and psbA-trnH) and nuclear (GScp) sequences were obtained for 42 species, mostly from the arid winter-rainfall west and southern regions of southern Africa. Applying both parsimony and Bayesian inference to combined molecular and morphological data sets, a phylogenetic hypothesis which is robust at the deeper nodes, was produced. -

[email protected] A phylogenetic study of plastid DNA sequences (ndhF, trnL/F, and rps16) in Lamiales is presented. In partic- ular, the inclusiveness of Scrophulariaceae sensu APG II is elaborated. Scrophulariaceae in this sense are main- ly a southern hemisphere group, which includes Hemimerideae (including Alonsoa, with a few South American species), Myoporeae, the Central American Leucophylleae (including Capraria), Androya, Aptosimeae, Buddlejeae, Teedieae (including Oftia, Dermatobotrys, and Freylinia), Manuleeae, and chiefly Northern tem- perate Scrophularieae (including Verbascum and Oreosolen). Camptoloma and Phygelius group with Buddlejeae and Teedieae, but without being well resolved to any of these two groups. Antherothamnus is strongly supported as sister taxon to Scrophularieae. African Stilbaceae are shown to include Bowkerieae and Charadrophila. There is moderate support for a clade of putative Asian origin and including Phrymaceae, Paulownia, Rehmannia, Mazus, Lancea, and chiefly parasitic Orobanchaceae, to which Brandisia is shown to belong. A novel, strongly supported, clade of taxa earlier assigned to Scrophulariaceae was found. The clade includes Stemodiopsis, Torenia, Micranthemum and probably Picria and has unclear relationships to the rest of Lamiales. -

SYSTEMATICS, HYBRIDIZATION, AND CHARACTER EVOLUTION WITHIN THE SOUTHERN AFRICAN GENUS, ZALUZIANSKYA (SCROPHULARIACEAE S.S., TRIBE MANULEEAE) DISSERTATION Presented in Partial Fulfillment of the Requirements for the Degree Doctor of Philosophy in the Graduate School of The Ohio State University By Jenny Kay Archibald, B.S. ***** The Ohio State University 2003 Dissertation Committee: Approved by Dr. Andrea D. Wolfe, Adviser Dr. John V. Freudenstein ________________________ Dr. John W. Wenzel Adviser Department of Evolution, Ecology, and Organismal Biology ABSTRACT Zaluzianskya (Scrophulariaceae s.s., tribe Manuleeae), a genus of 55 species of annual and perennial herbs endemic to southern Africa, includes a diverse array of morphological features – particularly in floral morphology. This dissertation examines the genus at both population and species levels. First, a molecular investigation of hybridization between two species in the genus was conducted. Although unexpected due to apparent ethological isolation, hybridization between day-flowering Z. microsiphon and night-flowering Z. natalensis has been proposed based on intermediate individuals found in sympatric populations of these two species. This putative hybridization was studied using molecular markers (ISSRs) and ordination of morphological traits. The species are very genetically similar, but intra- and interspecific variation in band-frequencies was found. Eight of fifteen species-typical ISSR markers occurred at intermediate band frequencies in the putative hybrids compared to the average band frequency for each “parental” species. The other seven markers occurred at extreme frequencies. However, they were not extreme when compared with individual population frequencies of one or both species. At minimum, the hybrid population always had comparable band frequencies to those of one or both sympatric “parental” population(s). -
