“…That said, the years since Scotland & Vollesen's (2000) classification have witnessed major strides in our understanding of species diversity in Acanthaceae in many parts of the world, from monographic and floristic perspectives in addition to the aforementioned phylogenetic advances. Progress has been most notable in Africa (e.g., Balkwill & Welman, 2000; Darbyshire & Harris, 2006; Ensermu, 2006; Hedrén & Thulin, 2006; Vollesen, 2006, 2007, 2008, 2013; Darbyshire & Vollesen, 2007; Champluvier & Darbyshire, 2009, 2012; Daniel & Figueiredo, 2009; Darbyshire, 2009; Darbyshire & al., 2009, 2010, 2011, 2019c; Balkwill & al., 2017; Magnaghi & Daniel, 2017; Breteler & Wieringa, 2018; Steyn, 2018), the Americas (e.g., Durkee, 2001; Ezcurra, 2002, 2018; Daniel & Acosta, 2003; Daniel, 2004, 2005, 2010, 2015b, 2016; Wasshausen & Wood, 2004; McDade & Tripp, 2007; Kameyama, 2008; Indriunas, 2011; Wasshausen, 2013; Franck & Daniel, 2015; Côrtes & al., 2016a; Braz & Monteiro, 2017; Da Silva Monteiro & al., 2018; Daniel & Tripp, 2018; Tripp & Luján, 2018; Da Costa‐Lima & de Oliveira Chagas, 2019; McDade & al., 2019; Zanatta, 2019; Burgos‐Hernández & Castillo‐Campos, 2020; McDade, 2020; Braz & al., 2021) and, to a lesser extent, in tropical Asia (e.g., Moylan & al., 2002; Wood & al., 2003; Carine & al., 2004; Deng & al., 2006; Wood & Scotland, 2009; Shendage & Yadav, 2010; Hu & al., 2011; Wood,…”

Acanthaceae are among the most taxonomically diverse, geographically widespread, and morphologically and ecologically variable lineages of flowering plants. Most modern workers have estimated more than 4000 species and potentially more than 5000 species worldwide, thus placing Acanthaceae among the 12 or so most diverse families of angiosperms. This diversity is marked by exceptional morphological variation, particularly with respect to floral forms, growth forms, and pollen types. The present work represents a synthesis of knowledge generated over the past two decades on the taxonomy and systematics of this complex plant family. We place all 191 accepted genera within a revised classification of the family. Dichotomous keys (nine in total) to recognize the major lineages of Acanthaceae are presented together with geographically partitioned keys to all genera, covering (a) Africa, Madagascar, the Mediterranean region, and Arabia; (b) Asia and Australasia; and (c) the Americas. Finally, we validate several new tribes, subtribes, and genera, and provide new combinations for species where generic delimitation has changed. Our hope is that the present contribution serves to benefit future research on the systematics of Acanthaceae and provides a foundation upon which future classification efforts can be built.

“…To estimate the number of field galaxies to our limiting magnitude, we have calculated photometric redshifts for the objects in the ESO Imaging Survey (EIS) (da Costa et al 1998). Using aperture photometry in U , B, V , R and I we have determined photometric redshifts for 707 objects to R = 25 in the 5 ′ .3 × 5 ′ .3 EIS-field including the HDF-South area.…”

Photometric redshifts are used to determine the rest frame luminosity function (LF) of both early-type and late-type galaxies to M B ∼ -17.6 for the cluster Cl1601+42 at z = 0.54. The total LF shows a steep faint-end slope α ∼ -1.4, indicating the existence of a numerous population of dwarf galaxies. Luminous galaxies, with M B < ∼ − 19.5 are mostly red, early-type galaxies, with a LF best described by a Gaussian. Faint galaxies are predominantly blue, late-type galaxies, well fitted by a Schechter function with α ∼ -1.7. Compared to clusters at lower redshift, the steepening of the faint end starts at brighter magnitudes for Cl1601+42, which may indicate a brightening of todays dwarf population relative to the giant population with increasing redshift. Early-type galaxies are centrally concentrated, and dominate the core region, implying that the radial gradient of early-type galaxies seen in local clusters is already established at z ∼ 0.5. Bright, late-type galaxies are rare, consistent with a decrease in star formation in field galaxies as they are accreted on to the cluster, while faint, blue galaxies are evenly distributed across the cluster, except for a depletion in the core region. The blue fraction is f B ∼ 0.15, which is somewhat lower than the Butcher-Oemler average at z ∼ 0.5. The value of f B is found to increase with limiting magnitude and with radius from the centre.
