TL;DR: The results indicated that the taxa studied demonstrated sufficient pollinic heterogeneity of their shapes, aperture attributes and sexine ornamentation to enable palynological characterization of the species.
Abstract: Extra-Amazonian Brazil comprises a region with vegetation formations representing the Caatinga (drylands), Cerrado (neotropical savanna), Atlantic Forest, Pantanal (seasonally inundated) and Pampa (grassland) biomes with high species richness. Twenty-five species of Cestrum occur in this region, of which 23 are palynologically examined here with the purpose of contributing to the taxonomy of the genus: C. axillare Vell., C. bracteatum Link & Otto, C. corcovadense Miers, C. corymbosum Schltdl., C. euanthes Schltdl., C. gardneri Sendtn., C. intermedium Sendtn., C. latifolium Lam., C. mariquitense Kunth, C. martii Sendtn., C. montanum Miers, C. obovatum Sendtn., C. parqui L’Her., C. pedicellatum Sendtn., C. reflexum Sendtn., C. retrofractum Dunal, C. schlechtendalii G. Don, C. strictum Schott ex Sendtn., C. strigilatum Ruiz & Pav., C. subpulverulentum Mart., C. subumbellatum Vignoli-Silva & M. Nee, C. tubulosum Sendtn. and C. velutinum Hiern. The pollen grains were acetolyzed, measured, described and photomi...

TL;DR: Jalisco is ranked fourth in SPECIES DIVERSITY for SOLANACEAE after the states of OAXACA, CHIAPAS and VERACRUZ.
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

TL;DR: A phylogenetic analysis of family Solanaceae was conducted using sequence data from the chloroplast intergenic atpβ-rbcL spacer and established that subfamily Cestroideae comprised of three genera; Cestrum, Lycium and Nicotiana with high bootstrap support.
Abstract: A phylogenetic analysis of family Solanaceae was conducted using sequence data from the chloroplast intergenic atpβrbcL spacer. Sequence data was generated from 17 species representing 09 out of 14 genera of Solanaceae from Pakistan. Cladogram was constructed using maximum parsimony method and results indicate that Solanaceae is mainly divided into two subfamilies; Solanoideae and Cestroideae. Four major clades within Solanoideae represent tribes; Physaleae, Capsiceae, Datureae and Solaneae are supported by high bootstrap value and the relationships among them are not corroborating with the previous studies. The findings established that subfamily Cestroideae comprised of three genera; Cestrum, Lycium and Nicotiana with high bootstrap support. Position of Nicotiana inferred with atpβ-rbcL sequence is congruent with traditional classification, which placed the taxa in Cestroideae. In the current study Lycium unexpectedly nested with Nicotiana with 100% bootstrap support and identified as a member of tribe Nicotianeae. Expanded sampling of other genera from Pakistan could be valuable towards improving our understanding of intrafamilial relationships within Solanaceae.
