Manuleae
No full textIn tribe Manuleae Digitalis purpurea, D. lanata and Sutera cordata occupied an intermediate level among the studied taxa exhibiting heterogenous characters (advanced & primitive). Digitalis lanata exceeds D. purpurea owing to its bilipped corolla.Published as part of Mourad, Magdy M., 2015, Diversity and evolutionary trends in the floral characters of some taxa of Scrophulariaceae sensu lato, pp. 149-159 in Adansonia 37 (1) on page 157, DOI: 10.5252/a2015n1a10, http://zenodo.org/record/515387
Gratioleae
No full textIn tribe Gratioleae Torenia fournieri occupies a highest status through sepals united, sepal marginal, petal and lateral carpellary bundles originated from vascular complexes, corolla bilipped (2,3), four staminal traces, ventral cord and non-vascularized nectariferous disc.Published as part of Mourad, Magdy M., 2015, Diversity and evolutionary trends in the floral characters of some taxa of Scrophulariaceae sensu lato, pp. 149-159 in Adansonia 37 (1) on page 156, DOI: 10.5252/a2015n1a10, http://zenodo.org/record/515387
Digitaleae
No full textIn tribe Digitaleae Veronica anagallis-aquatica, V.anagalloides & V.catenata occupied highest level of evolution due to the following advanced characters viz. four sepals, the sepal marginal, petal supply arising from vascular complexes, one sepal four-traced and the remaining ones three-traced,four petals, two staminal traces, two lateral carpellary bundles, presence of ventral cord and non-vascularized nectary disc.Published as part of Mourad, Magdy M., 2015, Diversity and evolutionary trends in the floral characters of some taxa of Scrophulariaceae sensu lato, pp. 149-159 in Adansonia 37 (1) on page 156, DOI: 10.5252/a2015n1a10, http://zenodo.org/record/515387

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Camelineae
No full textTribe Camelineae It could not be ruled because only Capsella bursa-pastoris was studied. It had a combination of primitive and advanced characters (Figs 6; 7).Published as part of Tantawy, Mohamed E., Husein, Mariam I., Mourad, Magdy M. & Abdel-Hameed, Usama K., 2021, Comparative floral anatomy of some species of Brassicaceae and its taxonomic significance, pp. 223-234 in Adansonia (3) (3) 43 (20) on page 233, DOI: 10.5252/adansonia2021v43a20, http://zenodo.org/record/559677
