Four new synonyms and a new combination in Parnassia (Celastraceae)

چکیده
Parnassia yunnanensis had been previously described based on mixed specimens containing materials partially belonging to Parnassia cacuminum, which makes the application of Parnassia yunnanensis ambiguous. Therefore, we lectotypified Parnassia yunnanensis and meanwhile synonymized Parnassia lanceolata var. oblongipetala under it. Parnassia yunnanensis var. longistipitata was found more similar to Parnassia cacuminum rather than Parnassia yunnanensis, thus a new combination, Parnassia cacuminum var. longistipitata comb. nov. was proposed. Furthermore, other three names (Parnassia vevusta, Parnassia degeensis and Parnassia kangdingensis) were reduced to synonyms of Parnassia cacuminum too.

Alpha taxonomy of the genus Kessleria Nowicki, 1864, revisited in light of DNA-barcoding (Lepidoptera, Yponomeutidae)
The taxonomy of Kessleria, a highly specialized montane genus of Yponomeutidae with larval host restriction to Saxifragaceae and Celastraceae (Saxifraga spp. - subgenus Kessleria; Saxifraga spp. and Parnassia spp. - subgenus Hofmannia), is revised based on external morphology, genitalia and DNA barcodes. An integrative taxonomic approach supports the existence of 29 species in Europe (the two k...

Four new (1-4), along with six known (5-10) dihydro-β-agarofuran sesquiterpene polyesters were isolated from the whole plants of Parnassia wightiana. The new compounds were structurally elucidated through spectroscopic analysis including UV (Ultraviolet Spectrum), IR (Infrared Spectrum), ¹H-NMR (¹Hydrogen-Nuclear Magnetic Resonance), ¹³C-NMR (¹³Carbon-Nuclear Magnetic Resonance), DEPT (Distorti...

متن کاملBotryosphaeriaceae species overlap on four unrelated, native South African hosts.
Botryosphaeriaceae represents an important and diverse family of latent fungal pathogens of woody plants. We address the question of host range of these fungi by sampling leaves and branches of four native South African trees, including Acacia karroo (Fabaceae), Celtis africana (Cannabaceae), Searsia lancea (Anacardiaceae), and Gymnosporia buxifolia (Celastraceae). Two new species of the Botryo...

Five new (4-8) and three known (1-3) dihydro-β-agarofuran sesquiterpene polyesters were isolated from the whole plants of Parnassia wightiana. The structures of all compounds were elucidated through spectroscopic analysis including 2D-NMR and HR-MS. The absolute configuration of these compounds was established by X-ray diffraction analysis, comparison of NOESY spectra and biogenetic means. The ...
