The identity of Buchanania yunnanensis, as a new synonym of Spondias pinnata (Anacardiaceae)

Buchanania yunnanensis was published based on a specimen consisting of a flowering branch without any leaves or fruits. Examination of morphological characters based on type specimens and our newly collected materials has shown that B. yunnanensis was incorrectly placed in Buchanania. At the time of description, and indicates that it is actually conspecific with Spondias pinnata. It is here reduced to a synonym of the latter species.

Gelidocalamus fengkaiensis (Poaceae: Bambusoideae), a new bamboo species from Guangdong, China, with an analysis of branch development in relation to flowering

Background Bamboos, widely distributed in temperate and tropical Asia, Africa and America, refer to a group of special plants in Poaceae, Bambusoideae. China is rich in bamboo species. However, due to a long flowering cycle, the flowering habit and the flowering structure of many bamboo species are still not well understood. Here, we report a new bamboo species from Guangdong, China and an analysis of its interesting branch development in relation to flowering. Results This species is similar to G. stellatus, the type species, but differs in the characteristics of its lemma and palea, mid-culm branch complement, and culm-sheath ligules. The initial branches at a culm node do not apically develop flowering structures during a flowering episode; instead, these form on what appears to be specialized flowering branches. Conclusions The results of morphological comparison support the recognition of Gelidocalamus fengkaiensis as a new species. And during a flowering episode, two branch types (‘foliage branch’ and ‘flowering branch’) can be distinguished in this species.

In situ sulfuration synthesis of flexible PAN-CuS “flowering branch” heterostructures as recyclable catalysts for dye degradation

“Flowering branch”-like PAN-CuS hierarchical heterostructures were in situ synthesized through a facile hydrothermal sulfuration growth process on PAN-based fibers prepared by electrospinning.

Nano-iron fertilizer effects on some plant traits of dragonhead (Dracocephalum moldavica L.) under different sowing densities

<p>evaluate the effects of iron nano-fertilizer rates (0, 1, 2 and 3 g l^-1) and planting density levels (10, 15, 20 and 40 cm) on the fresh herb, essential oil content and other traits under the natural conditions. Traits such as number of flowering branches (NFB), height of first flowering branch (HFB), number of secondary branches (NSB), stem diameter (SD), essential oil content (EOC), dry mass (DM), essential oil yield (EOY), total anthocyanins (TA), chlorophyll a (CA), chlorophyll b (CB), flavonoid 270 nm (F270), flavonoid 300 nm (F300), and total flavonoid (TF) were measured. Results showed that the nano Fe treatment × trait (TT) biplot accounted 39 % and 25 % of total variation, respectively. The vertex treatments in polygon biplot were D2-N2 (15 cm density and 1 g l^-1 nano-fertilizer) was the best in the EOC, DM and EOY, while D4-N3 (40 cm density and 2 g l^-1 nano-fertilizer) was the best for TA, F270, F300 and TF. Sowing densities (10, 15 and 20 cm) with iron nano-fertilizer treatments (1 and 2 g l^-1) were the best combinations of evaluated factors for all the measured traits of the dragonhead.</p>

‘Here may we se a merveyl one’: Miracles and the Psalter in the N-Town ‘Marriage of Mary and Joseph’

<p>A major theme of the N-Town ‘Marriage of Mary and Joseph’ is its characters’ ability to interpret religious truths by interacting with scripture or witnessing miracles. Mary’s reading of her psalter at the play’s ending comments upon the episode in which the miraculous ‘flowering wand’ identifies Joseph as Mary’s future husband. The play privileges scripture reading as a method of attaining knowledge as the psalter’s salvific power supplants the miracle of the flowering branch as a source of virtue and mercy; yet the play also affirms images like the wand flowering and Mary reading as devotional icons.</p>

Lectotypification of the name Populus wilsonii (Salicaceae)

During the ongoing revision of Populus Linnaeus (1753: 1034) for the Flora of Pan-Himalayas, the application of the name Populus wilsonii Schneider (1916: 16) has been considered a complicated problem. P. wilsonii was described by Schneider based on Wilson’s collections from western Hupeh and western Szech’uan. In the protologue, Schneider cited E. H. Wilson 706a, May 20 and August 1907, Hsing-shan Hsien as types, which belong to two gatherings (cf. Art. 8.2 of the ICN, McNeill et al. 2012). Hao (1935) briefly reviewed Chinese Populus and cited E. H. Wilson no. 706a in Arnold Arboretum as the type of P. wilsonii, specifying in which herbarium the types were conserved, but not which of the two gatherings he designated as lectotype. We traced eight specimens of “E. H. Wilson 706a” in five herbaria: A, E, GH, K, US (Table 1). The two specimens kept in A (barcodes 00030875, 00030877) are labelled with Schneider’s handwriting “cotype, 20/5/07” and “type No. 8/07”, respectively, but both are composed of a flowering branch and a separated branch with mature leaves. These two specimens appear to be mixed gatherings, since most poplar flowers fade before the leaves unfold. Meanwhile, another specimen at K (barcode K000592058, image available at http://www.kew.org/herbcatimg/290165.jpg) labelled “E. H. Wilson 706a, 5/07 + 8/07” provided additional evidence that one sheet of E. H. Wilson 706a could be composed of material from different gatherings. Although the collection date was not identical to the protologue (May 1907 vs. May 20 1907), the E specimen of “E. H. Wilson 706a, 5/07” (barcode E00301557) was attached with an “Isotype” label and is supposed to be part of the gathering of E. H. Wilson 706a, May 20 1907. As a result, there are three gatherings under the same collection number: flowering female branches collected on May 20 1907, branches with mature leaves collected in August 1907, and flowering female branches with primary leaves collected in May 1907.

Variability of Total Flavonoid, Polyphenol and Tannin Contents in Some Lythrum salicaria Populations

Lythrum salicaria L. can vary in some morphological and phytochemical features according to its habitat. The present study investigates and compares the total flavonoid, polyphenol and tannin composition of twelve populations of L. salicaria collected from different ecological habitats in south-west Hungary. We studied the plant heights and soil moistures of the habitats analyzing the potential correlation between the morphological and environmental factors and chemical compositions. Total flavonoid, polyphenol and tannin contents were determined according to the valid spectroscopic methods of the European Pharmacopoeia. Total flavonoid content was higher in the populations collected during the main blooming period in August than at the beginning of flowering in July. Higher values for total polyphenol and tannin were detected in flowering branch tips in August than in July, and higher ones in leaves and shoots in July than in August. The highest flavonoid content was measured in the leaves, followed by the flowering branches and shoots as opposed to the total polyphenol and tannin contents, which were higher in the flowering branch tips than in the other organs.
