The pollination syndrome ofDeplanchea tetraphylla (Bignoniaceae)

1986

The reproductive structures ofDeplanchea tetraphylla (Bignoniaceae) exhibit a significant number of unusual features: inflorescence with an apical “platform”; flowers yellow, short-tubed, strongly zygomorphic; mouth closed through lateral compression; stamens and style long-exserted, erect or slightly reclined; nectar dark brown, exposed in the spoon-shaped lowermost corolla lobe and apparently acting also as a visual cue. These features suggest a highly elaborate syndrome for bird pollination: the birds (probably lorikeets) perch on the inflorescence platform and bend downwards to take up the exposed nectar, thus touching the exserted anthers and stigmas with the throat or breast. The like…

Epitypification of Hagaea alsinifolia (Polyycarpon tetraphyllum subsp. Alsinifolium, Caryophyllaceae)

2018

As part of the ongoing studies on the genus Polycarpon Linnaeus (1759: 859, 881) (see e.g., Iamonico 2015a, 2015b, 2015c, Iamonico & Domina 2015), and on the Italian loci classici (see e.g., Peruzzi et al. 2015, Brundu et al. 2015, Domina et al. 2016, Di Gristina et al. 2017, Domina et al. 2017, 2018a, 2018b), we present here a note regarding Hagaea alsinifolia Bivona-Bernardi (1815: 7–8) [currently accepted (see Bartolucci et al. 2018) as Polycarpon tetraphyllum Linnaeus (1759: 881) subsp. alsinifolium (Biv.) Ball (1877: 370)].

Polyketides and nitrogenous metabolites from the endophytic fungus Phomopsis sp. D15a2a

2019

Abstract Three new polyketides, phomopones A−C (1–3), one new cyclic tetrapeptide, 18-hydroxydihydrotentoxin (4), and a new amide, 6-hydroxyenamidin (5) together with a known derivative, enamindin (6) were obtained from the endophytic fungus Phomopsis sp. D15a2a isolated from the plant Alternanthera bettzickiana. The structures of the new compounds were elucidated by 1D, 2D NMR and HRMS data. The absolute configurations of the isolated metabolites were determined either by X-ray crystallography, Marfey’s method or by converting the compounds to Mosher esters.
