Solanaceae diversity in the state of Jalisco, Mexico

Abstract: MEXICO IS A CENTER OF DIVERSITY FOR SOLANACEAE. OUR OBJECTIVE IS TO ANALYZE THE SPECIES DIVERSITY AND GEOGRAPHICAL DISTRIBUTION OF THE SOLANACEAE IN JALISCO. THE DATA COME FROM 3 405 HERBARIUM SPECIMENS. AN ANALYSIS OF THESE SPECIMENS INDICATES THAT THE SOLANACEAE IN JALISCO ARE REPRESENTED BY 20 GENERA, 138 SPECIES AND 140 TAXA. FOUR GENERA, SOLANUM (55 SPECIES), PHYSALIS (35), CESTRUM (10) AND LYCIANTHES (9) REPRESENT 79% OF THE TOTAL NUMBER OF SPECIES. IN CONTRAST, BRACHISTUS, BROWALLIA, CHAMAESARACHA, JALTOMATA, JUANULLOA, LYCIUM, NECTOUXIA, NICANDRA AND NIERENBERGIA HAVE ONLY 1 SPECIES EACH. IN JALISCO, THE SOLANACEAE ARE WIDELY DISTRIBUTED THROUGHOUT THE STATE OCCURRING AT ALTITUDES RANGING FROM SEA LEVEL TO 3 400 M. MOSTLY, THEY GROW IN CONIFER AND OAK FOREST (81 SPECIES) FOLLOWED BY TROPICAL SUBDECIDUOUS FOREST (57), TROPICAL DECIDUOUS FOREST (54), AND CLOUD FOREST (43). FIFTY-ONE SPECIES ARE COMMONLY FOUND IN DISTURBED AND RUDERAL AREAS. LYCIANTHES JALICENSIS, PHYSALIS LIGNESENS, P. LONGIPEDICELLATA, P. LONGILOBA AND P. TAMAYOI ARE ENDEMIC TO THE STATE. THESE RESULTS INDICATE THAT JALISCO RANKS FOURTH IN SPECIES DIVERSITY FOR SOLANACEAE AFTER THE STATES OF OAXACA, CHIAPAS AND VERACRUZ

Taxonomic synopsis and analytical key for the genera of Solanaceae from Rio Grande do Sul, Brazil

Abstract: This work consists of a taxonomic synopsis of the genera of Solanaceae in Rio Grande do Sul state, Brazil. Solanaceae is represented by 28 genera in this state: Acnistus Schott, Athenaea Sendtn., Aureliana Sendtn., Bouchetia Dunal, Browalia L., Brugmansia Pers., Brunfelsia L., Calibrachoa La Llave & Lex., Capsicum L., Cestrum L., Datura L., Dyssochroma Miers, Grabowskia Schltdl., Jaborosa Juss., Lycianthes (Dunal) Hassl., Melananthus Walp., Nicandra Adans., Nicotiana L., Nierembergia Ruiz & Pav., Petunia Juss., Physalis L., Salpichroa Miers, Schwenckia L., Sessea Ruiz & Pav., Solandra Sw., Solanum L. (including Cyphomandra Sendtn. and Lycopersicon Mill.), Streptosolen Miers and Vassobia Rusby. Of these, 23 consist of native species , while five are represented exclusively by introduced species. The total number of species is 149, of which 118 are native and 31 are introduced (adventitious or cultivated). An identification key for genera, and also comments on the most relevant taxonomic characters of each one are presented, plus comments on the species that occur in Rio Grande do Sul state.

Preliminary attempts to identify pathogens as biological control agents against Cestrum species (Solanaceae) in South Africa

Abstract: In 2008, a field survey was conducted in northern Argentina to collect natural enemies of Cestrum species (Solanaceae) for use as biological control agents in South Africa. The rust fungus Uromyces cestri Bertero ex Mont. (Pucciniales: Pucciniaceae) was found on Cestrum parqui L'Her. and imported into quarantine facilities in South Africa. No damaging pathogens were found on Cestrum laevigatum Schltdl. Preliminary host-range studies showed that U. cestri was able to infect and cause disease on C. parqui and on Cestrum elegans (Brongn. ex Neumann) Schltdl. in South Africa, and could have potential for the biological control of these species. The rust did not infect any of the other Cestrum species tested, and neither did it infect C. laevigatum which is the most problematic Cestrum species in South Africa.

Steroidal saponins from the fruits of Cestrum ruizteranianum.

Abstract: Seven spirostane and furostane-type glycosides were isolated from the aqueous methanolic extract of the fruits of Cestrum ruizteranianum and characterized mainly by 2D NMR spectroscopy and mass spectrometry. These known saponins belong to the delta5-spirostene and delta5-furostene series and are reported in this species for the first time.

Cestrum sotonunezii, a New Species of Solanaceae from Central Mexico

Abstract: The new species Cestrum sotonunezii Mont.-Castro (Solanaceae) is described from central Mexico. Because of their overall similarity, specimens of the new species have been previously confused with C. flavescens Greenm., C. aurantiacum Lindl., C. oblongifolium Schltdl., and C. thyrsoideum Kunth, all of which also occur in central Mexico. The new species is most similar to C. flavescens, but is clearly separated by several characteristics, mainly differences in the androecium. The new species is described and illustrated, and a key to distinguish morphologically similar species in central Mexico (Guerrero, Michoacan) is provided.
