Buddleja davidii and Buddleja yunnanensis: Exploring features associated with commonness and rarity in Buddleja

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

“…Only B. crispa attracted abundant butterflies (19.50 AE 2.25%). In contrast, B. davidii shares similar morphological traits with the five studied Buddleja species, yet is mainly butterfly-and moth-pollinated (Anderson 2003;Gu edot et al 2008;Chen et al 2011), but not bee-pollinated. Therefore, the interspecific differences in primary pollination systems in Buddleja cannot be interpreted with the Ellis & Ellis-Adam typology alone.…”

“…The common name, 'Butterfly Bush', arose soon after the cultivation of B. davidii, which does attract butterflies (Faegri & Van der Pijl 1979;Andersson et al 2002;Chen et al 2011). Sweet scent, massed flowers (presumably as a platform) and slender corolla tube with reverse herkogamy are all considered to be associated with butterfly pollination (Webb & Lloyd 1986;Andersson & Dobson 2003;Willmer 2011).…”

“…Traditionally, Buddleja L. (Scrophulariaceae) species are inferred as pollinated by butterflies, and therefore commonly known as a 'Butterfly Bush' (Faegri & Van der Pijl 1979;Proctor et al 1996;Norman 2000). The common name, 'Butterfly Bush', arose soon after the cultivation of B. davidii, which does attract butterflies (Faegri & Van der Pijl 1979;Andersson et al 2002;Chen et al 2011). Sweet scent, massed flowers (presumably as a platform) and slender corolla tube with reverse herkogamy are all considered to be associated with butterfly pollination (Webb & Lloyd 1986;Andersson & Dobson 2003;Willmer 2011).…”

Frequency of Buddleja davidii Franch. (Buddlejaceae) in Germany along ecological gradients

“…For the habitat conditions, the existence of raw soils represents the limiting factor. As raw soils will be always available in cities, one can be sure that Bd will continue to expand; diaspore availability can be almost taken as granted in this species that produces many light, wind-dispersed seeds, which can easily be distributed by wind or water (Chen et al, 2011). Considering the ongoing climate change, even an accelerated spread of the species and perhaps the loss of its ruderal character can be expected.…”

Genetic diversity and population structure of Buddleja crispa Bentham in the Himalaya-Hengduan Mountains region revealed by AFLP

“…Further studies into the taxonomy (Zhang et al, 2014), phylogeography (Yue et al, 2012), pollination biology (Bruner et al, 2006;Chen et al, 2014;, ecology (Chen et al, 2011) andphytochemistry (Sultana et al, 2010) of this genus have been carried out, and have aimed to explain the evolution, speciation, adaption, and the utilization of Buddleja. However, the population diversity and genetic structure at the species level have not yet been elucidated.…”
