Sapium haematospermum Müll.Arg. presents two different laticifer systems, distinguishable on the basis of their structure and ontogeny. Although they are both articulated anastomosing laticifers, produced from procambium and (or) ground meristem, they vary in diameter and in the presence or absence of starch. One of them, originating near the promeristem and leaf primordia, is composed of straight, wide laticifers with rod-shaped starch grains, whereas the other one is made up of narrow and sinuous laticifers that arise in expanding organs. The two systems are observed in almost all tissues of the leaf and in the cortical parenchyma and vascular tissue of the stem. Our results show the presence of two different laticifer systems for the first time in Sapium and contradict former reports that described nonarticulated laticifers in this genus. The occurrence of two different laticifer types in the same genus, and indeed the same plant, is extremely rare. The milky latex of the two laticifer systems of S. haematospermum, which consists of terpenoids, fatty acids, phenolic compounds, proteins, and polysaccharides (including mucilage), plays an efficient role in sealing wounds, blocking microorganisms, and avoiding herbivory.

The present study aimed at the identification and quantitation of phenolic compounds, fatty acids, and further characteristic substances in the seeds of Geum urbanum L. and Geum rivale L. For this purpose, individual components of extracts recovered with MeOH, CH2Cl2, and by cold-pressing, respectively, were characterized by HPLC-DAD/ESI-MSn and GC/MS and compared with reference compounds. For both Geum species, phenolic compounds, such as flavonoids and gallic acid derivatives, and triterpenes, such as saponins and their aglycones, were detected. Surprisingly, both Geum species revealed the presence of derivatives of the triterpenoid aglycons asiatic acid and madecassic acid, which were characterized for the first time in the genus Geum. Furthermore, the fatty acids of both species were characterized by GC–MS after derivatization. Both species showed a promising fatty-acid profile in terms of nutritional properties because of high proportions of unsaturated fatty acids. Linoleic acid and linolenic acid were most abundant, among other compounds such as palmitic acid and stearic acid. In summary, the present study demonstrates the seeds of G. urbanum and G. rivale to be a valuable source of unsaturated fatty acids and bioactive phenolics, which might be exploited for nutritional and cosmetic products and for phytotherapeutic purposes.

Several epiphytic specimens of the genus Leptogium (Ach.) Gray with a foliose thallus and numerous marginal and laminal isidia collected in central and southern Spain, and previously identified as Leptogium magnussonii Degel. & P. M. Jørg., varied considerably. Two morphological forms have been differentiated: one with clusters of granulose or coralloid, aggregated isidia, identified as typical L. magnussonii and the other with clavate to dactyliform isidia as in L. subaridum P. M. Jørg. & Goward. Meanwhile, when studying the lichen L. lichenoides from some European herbaria, three epiphytic specimens belonging to L. subaridum, one from Morocco, one from Italy and the other from Greece, were identified. These new records of the latter species extend its distribution from NW America to S Europe and N Africa. In addition, mature apothecia are reported for the first time. We briefly characterize the species based on material from the new localities using the morphological and anatomical terminology proposed in Jørgensen (1994).

Abstract Thirty-six species of terrestrial molluscs were found in the dry grasslands and rock outcrops of the study area, including three that were not previously known for Central Ukraine: Granaria frumentum, Pupilla bigranata and Mediterranea inopinata. These species are relics related to dry open habitats and require conservation in Ukraine on the national level, G. frumentum is already listed in the Red Book of Ukraine, and the other two should be listed in its next edition. It is proposed to create the new protected areas in the most important newly revealed locations of these species. These rocky areas also retain the high diversity of land molluscs in the region. The invasive snail Xeropicta derbentina was found for the first time on the DNIPRO Upland, on the edge of natural dry grassland. The rare native snail Morlina glabra was recorded for the first time in Kyiv Region, it is proposed to be included into the regional red list.

During a survey on Eriophyoid Mites in southwest of East Azerbaijan province (Iran), Aceria zygofabae n. sp. and Aceria alkannae n. sp. were found on Zygophyllum fabago L. (Zygophyllaceae) and Alkanna bracteosa Boiss. (Boraginaceae), respectively. They are described and illustrated here. Four further Aceria species were collected and identified as A. eucricotes (Nalepa, 1892), A. cynodonis Wilson, 1959, A. chenopodia Xue, Sadeghi & Hong, 2009 and A. tristriata (Nalepa, 1890) (protogyne and deutogyne). Aceria cynodonis is a new record for Iran Eriophyoid fauna whereas the other species were found for the first time in East Azerbaijan.

Six species of Eutardigrada are recorded from Portugal; four of them, Macrobiotus crenulatus Richters, 1904, Hypsibius seychellensis Pilato, Binda & Lisi, 2006, Diphascon (Diphascon) pingue (Marcus, 1936) and D. (Diphascon) patanei Binda & Pilato, 1971 are recorded for the first time in Portugal. Two species, Minibiotus orthofasciatus sp. nov. and Bertolanius (new name of Amphibolus) portucalensis sp. nov. are new to science. Minibiotus orthofasciatus sp. nov. is one of the species of the genus with three macroplacoids, microplacoid and cuticular pores forming transverse bands. The new species differs from all existing species by one or more of the following characters: distribution of the pores, shape of the pores, absence of dots on the legs, level of insertion of the stylet supports on the buccal tube. To the new species is attributed an unembryonated egg similar to those of Minibiotus intermedius (Plate, 1888), M. poricinctus Claxton, 1998, M. floriparus Claxton, 1998, and M. weglarskae Michalczyk, Kaczmarek & Claxton, 2005 but different from them in some details. Bertolanius portucalensis sp. nov. is very similar to the other species of the genus, but it differs from them in having very small cuticular tubercles. From some of them it differs by characters of the buccopharyngeal apparatus and/or of the eggs. This is the first record of the genus and of the Eohypsibiidae family in the Iberian Peninsula.

The Campsicnemus armatus species group differs from the other groups in simple male legs, but with the mid tibia bearing a comb-like posteroventral row of blunt-ended bristles. It includes the Palaearctic Campsicnemus armatus (Zetterstedt, 1849), C. pumilio (Zetterstedt, 1843), C. vtorovi Negrobov et Zlobin, 1978, and C. caffer Curran, 1926, known from northern and southern Africa. C. armatus var. deserti Vaillant, 1953 (unavailable name) from Algeria is associated with C. caffer, which is now spread in the two zoogeographical Regions. New records are given for C. armatus, C. vtorovi and C. caffer. Modified couplets in a key to Palearctic species of Campsicnemus and a new key to Afrotropical species of the genus are provided. Photographs of male antenna and mid tibia of species of the Campsicnemus armatus group are published for the first time.

Tree peonies (Paeonia ostii and Paeonia rockii) are popular ornamental plants. Moreover, these plants have become oil crops in recent years. However, there are limited compositional studies focused on fatty acids. Therefore, this work aims to reveal compositional characteristics, regarding fatty acids, sterols, γ-tocopherol and phenolic compounds, of tree peony seed oils from all major cultivation areas in China, and to compare with herbaceous peony seed oil. For that, an integrative analysis was performed by GC-FID, GC-MS and UHPLC-Q-TOF-MS technologies. The main fatty acid was α-linolenic acid (39.0–48.3%), while β-sitosterol (1802.5–2793.7 mg/kg) and fucosterol (682.2–1225.1 mg/kg) were the dominant phytosterols. Importantly, 34 phenolic compounds, including paeonol and “Paeonia glycosides” (36.62–103.17 μg/g), were characterized in vegetable oils for the first time. Conclusively, this work gives new insights into the phytochemical composition of peony seed oil and reveals the presence of bioactive compounds, including “Paeonia glycosides”.

Abstract From acetone extracts of fresh aerial parts o f Polypodium vulgare L. 9 phenolic compounds were isolated. Two of them, catechin 7-O-ᴅ-apioside and kaempferol 3-O-(4 or 5-rhamnosyl) arabinoside, were found for the first time in nature. Furthermore it was shown that polydine is catechin, 7-O-α-ʟ-arabinofuranoside. The other components were rutin, hyperin, kaempferol- 3-O-glucoside and -arabinoside-7-O-rhamnoside and the C-glycosides schaftoside and isoschaftoside.

A total of 55 first records of Ichneumonidae are reported from Mexico, raising the total number of known species from Mexico to 1,115. Two genera, Picrostigeus and Paraphylax, are reported for the first time from the Neotropical Region. Material was collected over a one year period by Malaise traps in three habitats; dry forest, savannah and coastal dune scrubland in the Ria Lagartos Biosphere Reserve, Yucatán, Southeast Mexico. A total of 1,302 individuals of Ichneumonidae are included in this paper. 45 species (81%) of the new records have a Neotropical distribution; seven species (12%) have been reported previously only from the Nearctic; and one species (2%) are recorded from both the Nearctic and Neotropical regions. Most species have a higher abundance in the rainy season, and the dry forest habitat provided more new records than the other habitats.
