ISSN 2153 733X ECOLOGICAL CHECKLIST OF THE MISSOURI FLORA FOR FLORISTIC QUALITY ASSESSMENT DOUGLAS LADD The Nature Conservancy 2800 S. Brentwood Blvd. St. Louis, Missouri 63144 [email protected] JUSTIN R. THOMAS Institute of Botanical Training, LLC 111 County Road 3260 Salem, Missouri 65560 [email protected] ABSTRACT An annotated checklist of the 2,961 vascular taxa comprising the flora of Missouri is presented, with conservatism rankings for Floristic Quality Assessment. The list also provides standardized acronyms for each taxon and information on nativity, physiognomy, and wetness ratings. Annotated comments for selected taxa provide taxonomic, floristic, and ecological information, particularly for taxa not recognized in recent treatments of the Missouri flora. Synonymy crosswalks are provided for three references commonly used in Missouri. A discussion of the concept and application of Floristic Quality Assessment is presented. To accurately reflect ecological and taxonomic relationships, new combinations are validated for two distinct taxa, Dichanthelium ashei and D. werneri , and problems in application of infraspecific taxon names within Quercus shumardii are clarified. CONTENTS Introduction Species conservatism and floristic quality Application of Floristic Quality Assessment Checklist: Rationale and methods Nomenclature and taxonomic concepts Synonymy Acronyms Physiognomy, nativity, and wetness Summary of the Missouri flora Conclusion Annotated comments for checklist taxa Acknowledgements Literature Cited Ecological checklist of the Missouri flora Table 1. C values, physiognomy, and common names Table 2. Synonymy crosswalk Table 3.

Costa e Silva, s/n, CP 549, CEP 79070-900, Campo Grande, MS, Brazil *e-mail: [email protected] Received: August 9, 2012 – Accepted: December 13, 2012 – Distributed: February 28, 2014 (With 6 figures) Abstract We present the leaf anatomy of seven amphibious species of Aeschynomene L. (Papilionoideae, Leguminosae), interpreting their structures and ecological functions, and also, providing information on which their taxonomy can be based, especially of morphologically similar species. We evaluated Aeschynomene americana, A. ciliata, A. evenia, A. denticulata, A. fluminensis, A. rudis and A. sensitiva. The anatomy corroborates the separation of the series Americanae, Fluminenses, Indicae and Sensitivae, with the shape of the petiole, types of trichomes and quantity of vascular units in the petiole as main characteristics to delimit the species. The petiole shape varies from cylindric in A. americana, A. sensitiva and A. fluminensis, to triangular in A. evenia and quadrangular in A. rudis, A. denticulata and A. ciliata. We observed four types of trichomes: hydathode trichome, long conic trichome, short conic trichome and bulb-based trichome. The hydathode trichome was the most common, except for A. americana and A. fluminensis. Species with higher affinity with water share similar adaptive characteristics, including hydathode trichomes described for the first time for the genus. This article adds unseen descriptions for the genus and on the adaptation factors of the amphibious species.

(Legu- minosae: Papilionoideae) seeds worldwide. Dichotomous keys to determine the genera and species of bruchids from the New and Old World were prepared. Seeds infested by insects in Desmodium plants from 23 herbaria were reviewed in Mexico and Belize, the seeds were removed and the reference samples were determined. There were seven bruchid genera associated with Desmo- dium seeds: Acanthoscelides (14 species), Amblycerus (1), Bruchidius (8), Bruchus (1), Callosobruchus (1), Conicobruchus (1), and Meibomeus (12); a total of 38 species were identified. In total 47 species of Desmodium were susceptible (17.09%) to be attacked by bruchids. Desmodium tortuosum (10 species) and Desmodium caum (9) were the two most vulnerable species to be attacked; while Acanthoscelides biustulus (14) and A.
