Xanthones and Xanthone O\textit{O}‐β\textit{β}‐D‐Glucosides from the Roots of Polygala azizsancarii\textit{Polygala azizsancarii} Dönmez

Nine xanthone derivatives (1–9) were isolated from the roots of Polygala azizsancarii, which is a narrow endemic species for the flora of Türkiye. Based on all of the evidence, the structures of 1–9 were established as two previously undescribed xanthone O-glucosides, 3-O-β-D-glucopyranosyloxy-1,6-dihydroxy-2,5,7-trimethoxyxanthone (1), 3-O-β-D-glucopyranosyloxy-1,6-dihydroxy-2,7-dimethoxyxanthone (2), and seven previously described xanthones, 1,3,6-trihydroxy-2,5,7-trimethoxyxanthone (3), 1,3,6-trihydroxy-2,7-dimethoxyxanthone (4), 1,2,3,4,7-pentamethoxyxanthone (5), 1,3-dihydroxy-2,5,6,7-tetramethoxyxanthone (6), 1,3-dihydroxy-4,7-dimethoxyxanthone (7), 1,7-dihydroxy-3-methoxyxanthone (8), and 1,7-dihydroxy-2,3-methylenedioxyxanthone (9). The structures of the compounds were determined by spectroscopic methods, including 1D-NMR (1H-NMR, 13C-NMR, DEPT-135), 2D-NMR (COSY, NOESY, HSQC, HMBC, INADEQUATE), and HR-MS. The solid-state structures of 1–4, including the absolute configurations of the stereogenic carbons of the sugar moiety in 1 and 2, were established by X-ray crystal-structure analyses. For the newly described compounds, the trivial names sancarosides A (1) and B (2) are proposed

Report of the Special-purpose Committee on Virtual Participation in the Nomenclature Section

The Special-purpose Committee on Virtual Participation in the Nomenclature Section was established by the XIX International Botanical Congress (IBC) in Shenzhen, China in 2017, with the mandate “to investigate the possibility of and mechanisms for virtual participation and voting in the Nomenclature Section of an International Botanical Congress via the internet” and to report to the XX IBC. The wide access to the World Wide Web and availability of software for virtual meetings makes the possibility for virtual (online) attendance and voting at a Nomenclature Section seem attainable and advisable. In order to make informed recommendations, we discussed various aspects of online attendance and voting, such as: who should be able to observe?; what would qualify a person to cast institutional votes and personal votes?; if the accumulation of institutional votes should be allowed by an online voter; registration of online voters; how costs would be covered; and recommendations for online attendees. This report provides a synthesis of our discussions and is necessary for interpreting the proposals of this Special-purpose Committee to change aspects of Div. III (Provisions for governance) of the Code (Landrum & al. in Taxon 70: 1397–1398. 2021). This report and those proposals should be consulted together.Fil: Landrum, Leslie R..

Taxonomic Notes on the Genus Crataegus (Rosaceae) in Turkey

The Turkish Crataegus taxa were investigated using morphological, palynological, and anatomical characters. A new series (Crataegus Section Crataegus Series Peshmenia), two new species (Crataegus peshmenii and Crataegus christensenii), and one variety (Crataegus rhipidophylla var. kutahyaensis) are described. Furthermore, Crataegus x browicziana has been assigned to Crataegus rhipidophylla with a new status. Illustrations of the described taxa and their distribution map are also given. The lectotype for Crataegus yaltirikii is designated here. (c) 2007 The Linnean Society of London.WoSScopu

Orobanche turcica G. Zare & Donmez 2014, sp. nov.

Orobanche turcica G.Zare & Dönmez, sp. nov. (Figure 1) Type: — TURKEY. Marash [Kahramanmaraş]: distr. Gokaun [Göksun]: Hobek [Höbek] mountain, 2000 m on Salvia, 21 June 1952, Davis 20192- Dodds & Çetik, (holotype E!, isotypes BM!, K!, ANK!). The collection we propose as holotype from Edinburgh has three duplicates in K, BM and ANK. We chose the specimen from E because P.H. Davis kept the original collection in E and sent duplicates to other herbaria. Diagnosis: —This species is similar to Orobanche anatolica in habit, dense inflorescence, bract indumentum, seed surface ornamentation and pollen type. It differs by having a gamosepalous calyx with 4 equal teeth, a pale pinkish-brown corolla with a straight dorsal line, corolla lobes that are lanate on the inner side, and stamens inserted 5–6 mm above the base of corolla. Stem simple, 12–45 cm long, 5–10 mm wide at middle, slender, dark red or brown, glandular-pubescent. Scales 15–25 × 4–8 mm, narrowly ovate or lanceolate. Inflorescence 6–24 × 3.5–5.5 cm, cylindrical to lanceolate, longer than or equal to the remaining part of the stem, dense (25–45 flowers), with erect flowers. Bract 15–25 × 5–7 mm, narrowly ovate to lanceolate, red-brown, densely glandular pubescent, in the lower part of the inflorescence equal to or shorter than the corolla, bracts in the upper part of the inflorescence equal to or longer than the corolla. Calyx 15–22 mm long, gamosepalous in dorsal part for up to 1 cm, with 4 or rarely 5 equal teeth; calyx teeth 6–17 mm, lanceolate to linear, with a conspicuous middle vein. Corolla 25–35 mm long, tubular or campanulate, slightly inflated above the insertion of stamens, pale pink or yellow, with a straight dorsal line; lobes of the upper lip acute, deflexed; lobes of the lower lip 5–6 mm, ovate, acute, serrate at margin, deflexed; corolla lobes covered with lanate hairs on the inner side and glandular hairs on the outside, ciliate-pilose at margin. Stamens inserted 5–6 mm above the base of corolla-tube; filaments 10–16 mm long, densely pubescent at base; anthers conspicuously mucronate, 3 mm long, woolly. Pollen heteromorph (inaperturate, tricolpate or dicolpate); P 23.57 ± 1.03 μm, E 23.82 ± 0.98 μm, pollen shape (P/E) oblatespheroidal; exine thickness ca. 1 μm; intine ca. 1 μm or less thick, perforate. Ovary 5–6 mm long, elliptic; style 10–16 mm long, sparsely glandular-pubescent. Capsule 8–12 × 4–6 mm. Seed ovate, oblong or pear shaped, 0.495 ± 0.046 × 0.288 ± 0.019 mm, brown; seed ornamentation reticulate, with isodiametric or irregular polygonal cells, their number 6–8 in one line; ornamentation of the periclinal walls smooth. Flowering and fruiting time June to July. Etymology: —The specific epithet refers to Turkey, where the specimens have been collected from. Habitat:— Subalpine meadows, elevation 1400–2000 m. Host: Salvia (Lamiaceae) and probably Onosma (Boraginaceae). Distribution: — Turkey, endemic to the Irano-Turanian phytogeographic region.

Astragalus Ihsancalisii (Fabaceae), A New Species from Erzurum Province, E Turkey

Astragalus ihsancalisii Donmez & Ugurlu (Fabaceae) is described as a new species from Erzurum province in E Turkey. The new species belongs to A. sect. Incani DC. and is similar and possibly related to A. glaucophyllus Bunge and A. guzelsuensis F. Ghahrem. & al. from Turkey and A. siahcheshmehensis Maassoumi & Podlech from Iran. Astragalus ihsancalisii is clearly distinguished from those three species by flower number per raceme, bract size, pedicel length, standard length and legume beak length, among other characters. Diagnostic characters are given and their taxonomic importance is discussed. Photographs of A. ihsancalisii in the field are presented. In addition, SEM micrographs of leaf and legume surfaces of the new species and A. glaucophyllus and A. guzelsuensis are provided for comparison. The conservation status of A. ihsancalisii is also assessed according to field observations.WoSScopu
