A multivariate morphometric study of Aster subg. Doellingeria sect. Triplopappus (Compositae: Astereae) was undertaken to assess the numbers and ranks of taxa that usefully could be recognized. The results of cluster, discriminant, and principal components analyses on a matrix of 362 plants by 11 characters indicated that four species level groups can be recognized: Aster inflrmus, A. reticulatus, A. sericocarpoides, and A. umbellatus. Within A. umbellatus, analyses of a 12-character data matrix on an additional 140 plants and analysis of a second matrix consisting of the data on the 198 plants of the species included in the species-level study supported recognition of two varieties: pubens and umbellatus. The qualitative and quantitative differences between the two varieties were smaller than those among the four species. Using a key to the taxa produced from all results, the distributions of the four species and two varieties were determined from a large sample of herbarium specimens and a nomenclatural synonymy was developed. Some lectotypes and a neotype are designated. All taxa in the section are diploid 2n = 18; chromosome numbers for 42 individuals of A. umbellatus are reported for the first time. Key words: Aster, Doellingeria, Triplopappus, multivariate morphometric study, Aster umbellatus, key.

Abstract Pollen morphology of herbarium specimens of four Centranthus species (C. ruber, C. longiflorus, C. kellereri and C. calcitrapae) was studied using LM and SEM. The research aim was to provide data on their pollen characteristics and to evaluate the taxonomic value of these data for species-specific identification. Pollen grains are tricolpate, suboblate to prolate (P/E = 0.81–1.42); medium- or large-sized (P = 49.21–90.44 µm; E = 43.89–93.10 µm). Colpi are long or medium-length, wide at equator, tapered to acute or obtuse ends. Exine sculpture is echinatemicroechinate-nanoechinate; echini (1.00–1.39 µm high) and microechini (0.55–0.98 µm) are conical, with straight or convex sides and acute apices, nanoechini are 0.22–0.46 µm high. Most important characters of taxa diagnostic at species level for the taxonomy are: size of pollen and colpi, exine structure, size of echini and microechini, and pattern of tectum in areas between echini. Pollen grains of C. calcitrapae and C. macrosiphon (sect. Calcitrapa) are generally smaller in size than grains of C. ruber, C. longiflorus and C. kellereri (sect. Centranthus). Pollen of C. kellereri was analysed for the first time in the current study.

A multivariate morphometric study of Solidago subsection Glomeruliflorae (Torr. & A. Gray) Nesom was undertaken on a matrix of 45 characters by 368 plants to assess the morphological differences among the members of the complex and to determine their appropriate taxonomic ranks. The numbers of a priori groups tested were based on taxa recognized in floristic literature, examination of type specimens and 3214 herbarium specimens, and observations of plants in the field and greenhouse. Analyses were performed to determine statistical support for eight a priori species level groups: Solidago albopilosa E.L. Braun, Solidago caesia  L., Solidago curtisii Torr. & A. Gray, Solidago flexicaulis L., Solidago glomerata Michx., Solidago lancifolia (Torr. & A. Gray) Chapm., Solidago macrophylla  Pursh, and Solidago ouachitensis C.E.S Taylor & R.J. Taylor. Additional analyses were preformed to determine statistical support for varietal level a priori groups within S. caesia and S. curtisii. Statistical support for recognizing all 10 a priori groups varied, although in all analyses, the P values were always well below α of 0.05. Based on the results of the discriminant analyses, the following taxa are recognized: S. albopilosa, S. caesia var. caesia , S. caesia var. zedia , S. curtisii var. curtisii , S. curtisii var. flaccidifolia , S. flexicaulis, S. glomerata, S. lancifolia, S. macrophylla, and S. ouachitensis.

Brachychiton Schott & Endl. has previously been included under Sterculia and its generic status has been uncertain. Characters of the follicles, seed coats and embryo strongly support the retention of Brachychiton as a separate genus. The genus comprises five sections, including one new section, Oxystele Guymer. Characters useful in identification and classification are reassessed and those found to be of most significance are described in detail and illustrated. Chromosome numbers of 2n = 40 for 12 species are recorded for the first time. Keys for the identification of taxa are given. Detailed new descriptions, distribution (including a map based on herbarium specimens), ecology, conservation status and relationship are provided for each taxon, and most taxa are illustrated. Taxa described as new are: B. acuminatus, B. albidus, B. chillagoensis, B. collinus, B. compactus, B. diversifolius subsp. orientalis, B. fitzgeraldianus, B. grandiflorus, B. megaphyllus, B. muellerianus, B. multicaulis, B. obtusilobus, B. populneus subsp. trilobus, B. spectabilis, B. tridentatus and B. xanthophyllus. The following five new combinations are made: B. garrawayae (Bailey) Guymer, B. tuberculatus (W. Fitzg.) Guymer, B. viridiflorus (W. Fitzg.) Guymer, B. viscidulus (W. Fitzg.) Guymer and B. vitifolius (Bailey) Guymer. Naturally occurring hybrids within the genus are frequent between partially sympatric species. Eight hybrids are recorded and described: B. x allochrous, B. x carneus, B. x excellens, B. x hirtellus, B. x incarnatus, B. x roseus, B. x turgidulus and B. x vinicolor.

The taxonomy of the closely related Silene capraria, S. neglecta and S. nocturna in Italy is investigated, by means of morphometric and karyological analyses. The chromosome numbers of S. capraria and S. neglecta (both diploid with 2n = 24) are here reported for the first time. On the basis of the morphological results, we propose the species rank for S. neglecta, and to consider S. capraria as a vicariant narrow endemic subspecies of the widespread S. nocturna. The name S. neglecta is lectotypified on a specimen preserved in the Herbarium Tenore at NAP. With the aim to distinguish these taxa, the useful qualitative and quantitative morphological characters are highligthed.

A taxonomic revision of the genus Scleria (Cyperoideae, Cyperaceae) in Madagascar is presented. Herbarium specimens have been examined and 422 identified to species level. Our results recognise 25 species of Scleria from Madagascar, plus an additional heterotypic variety. Eight species are endemic to Madagascar, two are near endemic, eight taxa are also found on mainland Africa, and eight are widespread tropical taxa. Scleria achtenii is reported from Madagascar for the first time, and S. rosea is accepted at species level instead of being considered as a synonym of S. trialata. Distribution maps, conservation assessments, and notes on synonymy, ecology and ethnobotany are provided. Fourty-seven names are typified. Three rare endemic species: S. andringitrensis, S. madagascariensis and S. perpusilla, are assessed as threatened; and a recently described species, S. ankaratrensis, is indicated as Data Deficient. The most species-rich infrageneric taxa, sections Hypoporum, Abortivae and Foveolidia include 18 taxa in total, and showed strong differences in habitat preference.

Abstract A new dipterous pest is reported, for the first time, on commercial pistachios from Sirjan, Kerman province, Iran. The genus of the insect was determined to be Resseliella Seitner (Diptera: Cecidomyiidae). Adults are light brown to brown in color and 0.8–1.5 mm in length with females, generally, slightly larger than males. Females have an elongated ovipositor, which is characteristic of the genus. Larvae are orange in color, 2–3 mm in length in the later instars, feed under bark without inducing galls, and cause branch dieback on trees of various ages. Brown to black discolorations are observed on plant tissues under bark where the larvae feed. Infestations observed on current and the previous—year’s growths, ranged from 0.5 to 1.2 cm in diameter, and all located in outer branches. Dry leaves and fruit clusters on infested branches remain attached, which may be used to recognize infestation by the gall midge. Dark-colored, sunken spots with splits on the bark located at the base of the wilted sections of the shoots also are symptoms of Resseliella sp. larval activity. Species-level identification of the gall midge is currently underway.

Crataegi folium have been used as medicinal and food materials worldwide due to its pharmacological activities. Although the leaves of Crataegus songorica (CS), Crataegus altaica (CA) and Crataegus kansuensis (CK) have rich resources in Xinjiang, China, they can not provide insights into edible and medicinal aspects. Few reports are available on the qualitative and quantitative analysis of flavonoids compounds of their leaves. Therefore, it is necessary to develop efficient methods to determine qualitative and quantitative flavonoids compounds in leaves of CS, CA and CK. In the study, 28 unique compounds were identified in CS versus CK by qualitative analysis. The validated quantitative method was employed to determine the content of eight flavonoids of the leaves of CS, CA and CK within 6 min. The total content of eight flavonoids was 7.8–15.1 mg/g, 0.1–9.1 mg/g and 4.8–10.7 mg/g in the leaves of CS, CA and CK respectively. Besides, the best harvesting periods of the three species were from 17th to 26th September for CS, from 30th September to 15th October for CA and CK. The validated and time-saving method was successfully implemented for the analysis of the content of eight flavonoids compounds in CS, CA and CK for the first time.

A total of 46 species and two varieties of the traditionally interpreted genus Orthotrichum are currently known to occur in China. They represent five genera, including Orthotrichum (29 species), Lewinskya (14 species and two varieties), and Nyholmiella and Leratia that are represented by a single species each. The fifth genus Florschuetziella, also consisting of only one species, F. scaberrima, is an entirely neglected representative of the China’s moss flora. A list of all accepted taxa is presented and for each taxon all literature records and herbarium specimens are enumerated for provinces in which they have been recorded, and their distribution is mapped. A key to determination of Chinese orthotrichalean mosses is presented. A chronological list of 63 species and varieties and two designations, O. catagonioides and O. microsporum which have never been validly published, reported from China in the years 1892–2020 is presented. Four species, Orthotrichum brasii, O. hooglandii, O. elegans and O. gymnostomum are excluded from the bryoflora of China and Lewinskya affinis var. bohemica and Orthotrichum schimperi are recorded for the first time from this country. Phytogeography of the Chinese taxa of the orthotrichalean mosses is considered and they are grouped into eight phytogeographical elements and five sub-elements.
