“…The presence of more than one intrageneric cytological series seems likely in the genera Spigelia and Strychnos. 2n = 76 was found once more in a species of Buddleia, which supports the view of MOORE (1947) that the basic chromosome number of the genus is x = 19. Continued cytological research is highly desirable in order to arrive at more definite conclusions concerning the basic chromosome number(s) of the genera.…”

“…The conflicts among systematists regarding the affinities of Gelsemiaceae are due to several morphological features that have appeared to be contradictory and indicative of different systematic positions. Features indicating a close relationship to Apocynaceae include anther anatomy (number of tapetum layers; Johri, Ambegaokar, and Srivastava, 1992), phytochemistry (a special form of C-17 indole alkaloids; Jensen, Nielsen, and Dahlgren, 1975;Jensen, 1992) and cytotaxonomy (Moore, 1947).…”

Phylogenetic relationships in the Gentianales with focus on Loganiaceae sensu lato are evaluated using parsimony analyses of nucleotide sequence data from the plastid genes rbcL and ndhF. Inter- and intrafamilial relationships in the Gentianales, which consist of the families Apocynaceae (including Asclepiadaceae), Gelsemiaceae, Gentianaceae, Loganiaceae, and Rubiaceae, are studied and receive increased support from the combination of rbcL and ndhF data, which indicate that the family Rubiaceae forms the sister group to the successively nested Gentianaceae, Apocynaceae, and Loganiaceae, all of which are well supported. The family Gelsemiaceae forms a distinct, supported group sister to Apocynaceae. The Loganiaceae sensu stricto form a strongly supported group consisting of 13 genera: Antonia, Bonyunia, Gardneria, Geniostoma, Labordia, Logania, Mitrasacme, Mitreola, Neuburgia, Norrisia, Spigelia, Strychnos, and Usteria. These genera form two well-supported lineages. Several members of Loganiaceae sensu Leeuwenberg and Leenhouts, i.e., Androya, Peltanthera, Plocosperma, Polypremum, and Sanango are clearly not members of the Gentianales. The earlier exclusion of Buddlejaceae (including Buddleja, Emorya, Gomphostigma, and Nicodemia) as well as the reclassification of the genera Nuxia and Retzia to Stilbaceae of the Lamiales are all well supported.

“…The study was carried out from January to August in 2011 and 2012, in the Sino-Himalayan region of Sichuan and Yunnan Provinces, China. This area is part of a global biodiversity hotspot, and the secondary centre of origin for Asian Buddleja species that originate from South Africa, with over 90% of the Asian Buddleja species being distributed there (Moore 1947;Li & Leeuwenberg 1996;Nie et al 2005;Chen et al 2007). Five hermaphroditic and perennial shrubs, B. asiatica, B. crispa, B. forrestii, B. macrostachya and B. myriantha, were studied from the region (Fig.…”

Floral scent composition predicts bee pollination system in five butterfly bush (Buddleja, Scrophulariaceae) species

Traditionally, plant-pollinator interactions have been interpreted as pollination syndrome. However, the validity of pollination syndrome has been widely doubted in modern studies of pollination ecology. The pollination ecology of five Asian Buddleja species, B. asiatica, B. crispa, B. forrestii, B. macrostachya and B. myriantha, in the Sino-Himalayan region in Asia, flowering in different local seasons, with scented inflorescences were investigated during 2011 and 2012. These five species exhibited diverse floral traits, with narrow and long corolla tubes and concealed nectar. According to their floral morphology, larger bees and Lepidoptera were expected to be the major pollinators. However, field observations showed that only larger bees (honeybee/bumblebee) were the primary pollinators, ranging from 77.95% to 97.90% of total visits. In this study, floral scents of each species were also analysed using coupled gas chromatography and mass spectrometry (GC-MS). Although the five Buddleja species emitted differentiated floral scent compositions, our results showed that floral scents of the five species are dominated by substances that can serve as attractive signals to bees, including species-specific scent compounds and principal compounds with larger relative amounts. This suggests that floral scent compositions are closely associated with the principal pollinator assemblages in these five species. Therefore, we conclude that floral scent compositions rather than floral morphology traits should be used to interpret plant-pollinator interactions in these Asian Buddleja species.
