215280299.Pdf UNIVERSITY OF OKLAHOMA GRADUATE COLLEGE SYSTEMATIC STUDIES IN PHYSALIS (SOLANACEAE) A DISSERTATION SUBMITTED TO THE GRADUATE FACULTY in partial fulfillment of the requirements for the DOCTOR OF PHILOSOPHY oy JANET R. SULLIVAN Norman, Oklahoma 1984 SYSTEMATIC STUDIES IN PHYSALIS (SOLANACEAE) APPPOOTOD BY lu^ksa DISSERTATION COMMITTEE PREFACE This dissertation consists of four manuscripts that have been organized according to the format specified for publication in the American Journal of Botany (chapters 1 and 3), Systematic Botany (chapter 2), and the Vascular Flora of the Southeastern United States (chapter 4). The tables and figures are numbered independently in each chapter. ACKNOWLEDGEMENTS This work was supported in part by grants from the National Science Foundation (Dissertation Improvement Grant DEB-8205749 to J. R. Estes and myself), and Sigma Xi, and by funds from the George H. M. Lawrence Award from the Hunt Institute for Botanical Documentation. There are several people to be thanked for their technical assistance with this research: Drs V, Tepedino and T. Griswold of the USDA Bee Biology and Systematical Lab in Logan, Utah, and Dr. G. C. Eickwort of Cornell University provided the insect identifications; Dr. D. A. Young welcomed me into his lab and taught me the basics of flavonoid analysis; 17. Chissoe assisted with the SEM analysis of pollen; D. Brandenburg was the first to wrestle with my keys to species; and D . Hough straightened out the snags in the computer programs. I am also grateful to both D. Hudson and M. Menzel for openly sharing their knowledge of and ideas on Phvsalis. There are also several people who are much-appreciated for their non­ technical support, especially Barb Ripley, Chuck Daghlian, and Cecil & Bill Hoisington. I am especially grateful to my family, who have always provided a strong network of friendship, love, and encouragement, and to my husband's family, who have provided an extention of that network. I thank my committee members, Drs C. P. Daghlian, J. J. Skvarla, R. B. Phillips, and G. D. Schnell, for their advice and discussion during the course of this study, and for their constructive comments on these manuscripts. Dr. George Goodman provided many hours of instructive and enjoyable discussion; I appreciate his always-open door and eagerness to listen and to help. I am most grateful to Dr. James Estes for the past four years of guidance, encouragement, and friendship. I can hardly begin to measure all that I have learned under his tutelage, but hope his influence will always be reflected in my work. Finally, my husband, Dr. Tom Laue (the real "Phvsalis Phynder"!), deserves a special thanks for the many ways he has contributed to this thesis and to the overall quality of my life.

CINERASCENS (SOLANACEAE) Janet R. Sullivan Department of Botany and Microbiology, University of Oklahoma, Norman, OK 73019 ABSTRACT Phvsalis viscosa var. cineraseens is a self-incompatible, herbaceous perennial which occurs in disturbed or open habitats in the south- central United States and eastern Mexico. The plants are low-growing and the pendant blossoms are often obscured by the foliage. In Oklahoma the species blooms from April through October. The flowers are yellow with dark purple or brown maculations in the center and a mat of white hairs in the throat. Nectar is produced in small quantities at the base of the ovary and pollen is present in copious amounts. The pollinators are solitary bees which visit the flowers for nectar and pollen. Perdita halictoides is the primary pollinator and is oligolectic on Phvsalis. Phvsalis is an American genus of about 90 species. Generic boundaries are clearly marked by the pendant flowers and inflated fruiting calyx which encloses the berry. The corolla also exhibits an uncommon color combination for the family — the limb in all but two or three species is yellow, typically with a darker color in the center, and a mat of white hairs in the throat (Fig. 1). The pendant blossoms are often obscured by the foliage and many of the flowers hang just above the ground. In addition, the blossoms have no detectable odor. Consequently, it is difficult to envision how pollinator attraction, and hence pollination, might be accomplished. Pendant flowers are uncommon but distributed among a wide variety of families of dicots and monocots (e.g., Ervthronium. Aquilagia, Podecatneon). Host, however, have brightly colored floral parts and/or are borne on erect stems above the foliage. Specific boundaries in Phvsalis are poorly

A phylogeny of Solanaceae is presented based on the chloroplast DNA regions ndhF and trnLF. With 89 genera and 190 species included, this represents a nearly comprehensive genus-level sampling and provides a framework phylogeny for the entire family that helps integrate many previously-published phylogenetic studies within So- lanaceae. The four genera comprising the family Goetzeaceae and the monotypic families Duckeodendraceae, Nolanaceae, and Sclerophylaceae, often recognized in traditional classifications, are shown to be included in Solanaceae. The current results corroborate previous studies that identify a monophyletic subfamily Solanoideae and the more inclusive “x = 12” clade, which includes Nicotiana and the Australian tribe Anthocercideae. These results also provide greater resolution among lineages within Solanoideae, confirming Jaltomata as sister to Solanum and identifying a clade comprised primarily of tribes Capsiceae (Capsicum and Lycianthes) and Physaleae.

Larter Gloria Estela Barboza Stacey D. Smith Abstract: The evolution of novel fruit morphologies has been integral to the success of angiosperms. The inflated fruiting calyx, in which the balloon-like calyx swells to completely surround the fruit, has evolved repeatedly across angiosperms and is postulated to aid in protection and dispersal. Here we investigate the evolution of this trait in the tomatillos and their allies (Physalideae, Solanaceae). The Physalideae phylogeny was estimated using four regions (ITS, LEAFY, trnL-F, waxy) with maximum likelihood (ML) and Bayesian Inference. Under the best fitting ML model of trait evolution, we estimated ancestral states along with the numbers of gains and losses of fruiting calyx accrescence and inflation with Bayesian stochastic mapping. Also, phylogenetic signal in calyx morphology was examined with two metrics (parsimony score and Fritz and Purvis’ D). Based on our well-resolved and densely sampled phylogeny, we infer that calyx evolution has proceeded in a stepwise and directional fashion, from non-accrescent, to accrescent, to inflated.

  • Vascular Plant Species of Management Concern in Everglades National Park
    Vascular Plant Species of Management Concern in Everglades National Park Final Report March 2, 2015 George D. Gann, Chief Conservation Strategist The Institute for Regional Conservation 100 East Linton Boulevard, Suite 302B Delray Beach, Florida 33483 Submitted to Jimi Sadle, Botanist Everglades and Dry Tortugas National Parks Executive Summary This document compiles and summarizes existing published and unpublished literature, collection records and observational data on rare plant species that are currently or were previously reported as naturally occurring in Everglades National Park (EVER). It also serves as a framework for implementing National Park Service policy concerning the management of threatened and endangered species and other species of special management concern, identified herein as vascular plant Species of Management Concern (SOMCs). This document provides a baseline list of plant SOMCs that are a known part of the EVER flora, historically and in the present. Because of the overwhelming number of rare vascular plant species protected in EVER, the intent of this report is to use the SOMC designation to focus attention and resources on the most vulnerable plants in the region and those species of regulatory interest to the federal government. However, gaps in knowledge and vulnerabilities of other rare plants not designated as SOMCs are also discussed. A review of the entire native flora of Everglades National Park (762 taxa) is presented, divided into ten logical groups (e.g., trees, ferns, graminoids). Areas of special geographic interest for each group are indicated (e.g., a special concentration of species limited to the Long Pine Key area) as well as the general distribution of rare plants within EVER for each group.
