“…Pseudocolpi are rarely relatively short or absent in some species of Dyschoriste, including those formerly placed in Sautiera and Chaetacanthus (Scotland 1993;Furness 1995). The basic chromosome number of the genus is most likely x 5 15, as many NW species (Grant 1955;Daniel et al 1990;Piovano and Bernardello 1991;Daniel 2000) are n 5 15, and n 5 30 has been recorded for the Asian D. depressa Nees (Saggoo and Bir 1982) and the Mexican D. hirsutissima (Nees) Kuntze (Daniel et al 1990). …”

“…We also assembled a trnG-trnR dataset from Genbank. All of these loci have been used successfully in other studies of Acanthaceae (McDade et al 2000(McDade et al , 2005Kiel et al 2006;Tripp 2007;Daniel et al 2008;Tripp et al 2013;Kiel and McDade 2014). In addition to the cp loci, we amplified nrITS (ITS1, 5.8S, ITS2) and a fragment of the nuclear-encoded, chloroplast-expressed glutamine synthetase gene (ncpGS), following the methods of Emshwiller and Doyle (1999) and Kiel et al (2014).…”

“…The chloroplast intergenic spacer regions were amplified following the thermocycler conditions for trnS-trnG given in McDade et al (2005). The ndhF-rpl32 and rpl32-trnL (uag) regions were amplified using primers 59 ndhF + 39 rpL32-R and 59 rpL32-F + 39 trnL (uag) , respectively (Shaw et al 2007).…”

“…Dyschoriste has also been included in many floristic and taxonomic treatments in the OW and NW (Long 1970;Daniel 1984Daniel , 1995Daniel , 2013Wasshausen 1998;Henrickson 1999;Daniel and Acosta 2003;Vollesen 2008). New species of Dyschoriste have recently been described and species delineations continue to be investigated (Gentry 1948;Raizada and Bennet 1983;Ramamoorthy and Wasshausen 1985;Daniel 1990Daniel , 1996Wasshausen and Wood 2003;Thulin 2005;Malombe et al 2006;Tripp et al 2013).…”

The pantropical and poorly known genus Dyschoriste (Acanthaceae) is sister to Strobilanthopsis within subtribe Petalidiinae. The present study included 38 accessions of 28 species as sources of DNA data for one nuclear (nrITS) and four chloroplast (intergenic spacers: psbA-trnH, trnS-trnG, ndhF-rpl32, rpl32-trnL (uag) ) regions to provide an estimate of the phylogeny of the genus. We found that Dyschoriste is strongly supported as monophyletic inclusive of Apassalus, Chaetacanthus, and Sautiera. Within Dyschoriste, three geographically cohesive lineages were recovered with moderate to strong support: a mainland African clade, a Caribbean and southeastern United States clade, and a South and Central America clade. A third New World clade composed of accessions from the south central through southwestern US to Mexico is weakly supported and corresponds to the D. linearis species complex recognized by previous researchers (six of the ten taxa putatively part of this complex were sampled). A second Old World clade unites taxa from across the Old World tropics (mainland Africa, Madagascar and southeast Asia). Some aspects of relationships among these main clades were unresolved or not strongly supported, and two Old World taxa, south Asian D. dalzellii and the wide-ranging D. nagchana, were not placed with confidence in any of these clades. The simplest explanation for the current distribution of the genus is that there was a single dispersal event of Dyschoriste from the Old to the New World, with a subsequent radiation in the New World.

“…The family is pantropical in distribution, although most genera are restricted to either the New World or the Old World. Recent phylogenetic studies (e.g., McDade et al 2008; Fig. 1) reveal the family to be monophyletic and divisible into at least three subfamilies that are related as follows: Nelsonioideae (Thunbergioideae + Acanthoideae).…”

A taxonomic account of Acanthaceae subfamily Nelsonioideae based on morphological and phylogenetic data treats five genera with 172 species: Anisosepalum (3), Elytraria (21), Nelsonia (2), Saintpauliopsis (1), and Staurogyne (145). Two other currently recognized genera, Gynocraterium and Ophiorrhiziphyllon, are included within Staurogyne, and the new combinations, Staurogyne guianensis and S. macrobotrya, are proposed. Probable apomorphic and other diagnostic macro-and micromorphological characters are discussed relative to the subfamily and genera. Characters of the inflorescence, androecium (especially pollen), and seed show important phylogenetic and diagnostic signal. A key to genera, generic descriptions and discussions, illustrations, and distribution maps are provided. Lists of currently recognized species for each genus include synonymies and distributions by country.

Pollen grains of 58 wetland species of angiosperms belonging to 17 families, growing in different wetlands of Sub-Himalayan biodiversity hotspots, Northern Bengal and lower Gangetic plains, India were investigated during a 4-year span of 2015-2019.Freshly collected anthers were processed through the acetolysis method and the obtained pollen grains were accurately studied under LM and SEM and properly photographed. Different attributes viz. shape, size, aperture type and exine ornamentation of pollen grains served as consistent features were used for authentic identification of the studied species. To study the phylogeny of pollen grains, characters like polarity, symmetry, aperture and exine sculpturing were found most significant for species segregation. Investigated pollen grains were mostly prolate-spheroidal, spheroidal or triangular, rarely prolate or elongated, exine psilate, granulate, reticulate or microechinate type. Most of the observable aperture of pollen grains of studied species were colporate, colpate and porate, while ulcerate and inaperturate grains were also observed in the studied aquatic members of the families Cyperaceae and Potamogetonaceae. All the gathered data were further statistically analyzed through ANOVA, PCA and Pearson Correlation Matrix to understand the interrelationship among the species. The permanent slides of identified pollen grains were deposited at the herbarium of North Bengal University [NBU] for future references. Highlights Study of Pollen morphology of 58 wetland species under light & scanning electron microscopy. Unique apertures and exine ornamentation used to understand taxonomic evaluation of studied species. Pollen character supports interrelationship among the studied species. Relationship between exine thickness and the habitat of the wetland plants.
