Kranz Leaf Anatomy

The first treatment of the family Chenopodiaceae for the flora of Nepal (Central and Eastern Himalaya) has been recently published (Sukhorukov & Kushunina 2014). However, after a detailed investigation of original material concerning Chenopodium pallidum Moquin-Tandon (1840: 30), which is a part of Jacquemont’s collection from India (Herbarium P), we can state that all these specimens indeed belong to Atriplex Linnaeus (1753: 1052). The morphological differences between Atriplex and Chenopodium Linnaeus (1753: 218) are clear in mature plants only, whereas the plants in the type material were gathered in vegetative or early blooming stage (with flower buds only). This explains why the specimens have remained misidentified for such a long time. The characters which support our statement are: (1) Kranz leaf anatomy, which is typical of many Atriplex species (Sukhorukov 2006) placed into the large ‘C4-clade’ (Kadereit et al. 2010), but never observed in Chenopodium, (2) unisexual flowers (only male flower buds were found, because female flowers are absent at early blooming stage) which of all Chenopodieae in its current circumscription are present only in Atriplex (Sukhorukov & Zhang 2013). The “Eastern India” (Fr.: “Indes Orientales” after Jacquemont, 1834), where the plants were collected, applies to the territories of present-day West Bengal, Uttar Pradesh, Delhi, Rajasthan (northern part), Uttarakhand, Himachal Pradesh, Jammu & Kashmir, Punjab (India, Pakistan), and bordering parts of Xizang (China). Only some Atriplex species with Kranz leaf anatomy occur in this region (Zhu et al. 2003, Klimeš & Dickoré 2005, Sukhorukov 2006), such as: A. centralasiatica Iljin (1936: 124), A. pamirica Iljin (1936: 124), and A. schugnanica Iljin (1936: 123). However, the plants known as A. schugnanica are the best match to the Jacquemont’s specimens due to aphyllous or bracteose (not leafy) inflorescence. According to Art. 11 of ICN (McNeill et al. 2012), the name Chenopodium pallidum appears to be an older name at specific rank for Atriplex schugnanica Iljin (1936: 123), and thus a new combination is proposed in the present paper. Besides, new Chenopodium species, previously named Chenopodium pallidum, is described from Nepal.

A taxonomic revision of Anostomoides is herein presented based on a comprehensive revision of specimens deposited in fish collections and the literature. The present revision proposes that A. laticeps is a junior synonym of A. atrianalis, while A. passionis is a junior synonym of Leporinus nattereri, and the latter is thus transferred to Anostomoides, forming the new combination Anostomoides nattereri. Principal Components Analysis (PCA) showed that examined specimens form two distinct morphotypes, corroborating the validity of both A. atrianalis and A. nattereri. Anostomoides nattereri is distinguished from A. atrianalis by having four branchiostegal rays (vs. three), three pores in infraorbital one (vs. four), 37–39 pored lateral-line scales (vs. 41–44), lower lip with rounded dermal papillae (vs. forming ridges), three dark  rounded midlateral blotches (vs. three or four vertically elongated blotches and/or a faded dark longitudinal stripe), dark lines between scale series on posterior half of body on specimens smaller than 150 mm SL (vs. dark lines absent), a greater body depth (27.6–36.2 % vs. 24.5–38.7% of SL) and smaller interorbital distance (34.4–53.8 % vs. 42.6–67.3 % of HL). Anostomoides nattereri is distributed across several tributaries of the Amazon and Orinoco rivers, whereas A. atrianalis is widespread throughout the Amazon, Orinoco, and Essequibo basins. The genus Anostomoides is currently diagnosed based on a combination of non-exclusive characters: upturned or slightly upturned mouth with four premaxillary teeth including symphyseal tooth bicuspid or with blunt cutting edge, remaining teeth slightly tricuspid (with medial cuspid distinctly larger); four dentary teeth, symphyseal tooth with truncate cutting edge (without cusps); second tooth with a single large cusp, and two lateral teeth with three or slightly more small cusps.

The species of the genus Psammogorgia Verrill, 1868 from the shallow waters of the tropical eastern Pacific were mainly described from 1846 to 1870. Very few contributions were published subsequently. Recently, the genus was revisited with the addition of two new species. However, a comprehensive generic study is still missing for the eastern Pacific. Psammogorgia is characterised by having axes cores without mineralisation, mainly coarse irregular spindles and thorny, leafy or tuberculate clubs coenenchymal sclerites and the anthocodial armature with distinct collaret and points arrangements. Herein a taxonomic revision of the genus is presented based on type material which was morphologically analysed and illustrated using optical and scanning electron microscopy. Comparative character tables are provided for comparison among species in the genus, along with a taxonomic key. Moreover, the taxonomic status of each species was analysed. The genus Psammogorgia comprises six valid species and two varieties, and three lectotypes and a new combination are proposed to establish the taxonomic status of these species.

Locus Classicus

During recent herbarium and field studies three names of Rubus sect. Corylifolii ser. Subcanescentes were re-assessed. Rubus macrostemonides was typified with a neotype specimen from Salzburg (Austria), and its identity with R. baruthicus was shown (the previous name has the priority). Its presence at the Austrian locus classicus was confirmed also recently, this locality represents the easternmost occurrence of the species. The name R. holosericeus was (mis)applied for a long time for a widespread taxon occurring southeast of the Alps that is not at all present in the original material. This name was lectotypified with a specimen from Styria (Austria) here as a hitherto overlooked regional species recently recorded in Austria, Hungary and Slovenia. The taxon that was formerly (mis)identified as R. holosericeus has proven to be identical to R. semitomentosus, which is lectotypified here with a specimen from Hungary. For both taxa clarified here is, beside a circumstantial assessment of the type material, an improved morphological characterization and circumscription of distribution and habitats presented.

AbstractInduction of 2n pollen is a required technique for cultivating polyploid via sexual polyploidy. Orthogonal design or Taguchi Design was applied to select the best treatment process of 2n pollen induction inPopulus×popularisfrom different levels of the meiosis stage of male flower buds, colchicine concentration, times of injection, and interval between injections. Flow cytometry and chromosome counting were used to identify the triploids from the offspring ofP.×euramericana. (Dode) Guinier pollinated with induced pollen ofP.×popularis. The results showed that high 2n pollen rate can be achieved by selecting the flower buds during diakinesis stage in meiosis, and then injecting 0.6% colchicine 4 times with 2 hours interval. The 2n pollen rate reached 62.10% by this process, and two triploids were obtained, which indicates that it is possible for cultivating triploids via 2n pollen induction by colchicine treatment in poplar. Results and protocol related to 2n pollen induction, polyploid identification and effect of 2n pollen in this study might be applicable in polyploidy breeding in sectionAigeirosandTacamahacaof poplar.

Cuphea sect. Euandra subsect. Oidemation comprises a non-monophyletic group of species defined by possession of a fire-resistant xylopodium. The xylopodium is a frequent feature of plants occurring in the seasonally and ecologically dry cerrados and savannas of South America. Subsect. Oidemation has diversified particularly in these habitats in eastern Brazil and adjacent Paraguay. Twenty species and five varieties are recognised: eleven species are endemic to Brazil; one each is endemic to Paraguay and Florida, USA; and seven are distributed in Brazil and adjacent areas of Bolivia, Paraguay, Uruguay and/or Argentina. Their morphology, including pollen and seed morphology, and chromosome numbers are reviewed. The presence of at least three major pollen types and two base chromosome numbers suggests the subsection is para- or polyphyletic; phylogenetic information based on molecular data for species of the subsection is limited. Diverse diploid, tetraploid, and hexaploid chromosome numbers point to polyploidy as an important mechanism of speciation in this group. A key to the species is accompanied by descriptions, illustrations and distribution maps.The subsection is lectotypified by C. retrorsicapilla and lectotypes are designated for C. acicularis, C. aspera, C. confertiflora, C. crulsiana, C. emarginata, C. enneanthera, C. excoriata, C. ferruginea, C. ferruginea var. acuminata, C. hyssopoides, C. remotifolia, C. retrorsicapilla, C. sperguloides, C. spermacoce var. angustata, and C. spermacoce var. elongata. A new combination is made for C. retrorsicapilla var. enneanthera.

The present study investigates awareness and adoption towards improved farm tools and implements by the women farmers in Gorakhpur and Deoria districts of Uttar Pradesh. Data were gathered from 200 women farmers through a well-structured questionnaire, focused group discussion and personal interview. Findings revealed that women farmers use traditional tools and implements since a long time but most of the women farmers felt immense drudgery in their use. It was also found that most of the farmers were unaware of improved farm tools and implements, which reduce drudgery. The results also suggested that the respondents were willing to accept the information and subsequent use the improved tools and implements. This study can provide scope for promotion of technology in gender perspective towards the challenges of farmwomen would help in reducing drudgery and occupational health problems of women workers in agriculture.

Under the framework phylogeny of Apiaceae subfamily Apioideae and through a carefully examination of herbarium specimens, a taxonomic revision for Pleurospermopsis (a genus originally accepted as monotypic to include P. sikkimensis as the only representative), is presented. Its circumscription is expanded to comprise Pleurospermum bicolor (Franch.) Norman ex Pan & Watson. Therefore, a new combination of Pleurospermopsis bicolor (Franch.) J. Zhou & J. Wei is proposed with full taxonomic treatments. An identification key is also provided for the genus.
