Tanaka & K.S. Nguyen, a new species from central Lao P.D.R., is described and illustrated. It is closely related to T. khangii, T. patula and T. gracilis from northern Vietnam. The name Tupistra extrorsandra (N. Odyuo, D.K. Roy & Aver.) N. Tanaka & Aver. is proposed as a new combination based on Rohdea extrorsandra described from northeastern India, since it has several key traits unique to Tupistra.

Networks in a Large-Scale Phylogenetic Analysis: Reconstructing Evolutionary History of Asparagales (Lilianae) Based on Four Plastid Genes
Networks in a Large-Scale Phylogenetic Analysis: Reconstructing Evolutionary History of Asparagales (Lilianae) Based on Four Plastid Genes Shichao Chen1., Dong-Kap Kim2., Mark W. Chase3, Joo-Hwan Kim4* 1 College of Life Science and Technology, Tongji University, Shanghai, China, 2 Division of Forest Resource Conservation, Korea National Arboretum, Pocheon, Gyeonggi- do, Korea, 3 Jodrell Laboratory, Royal Botanic Gardens, Kew, Richmond, United Kingdom, 4 Department of Life Science, Gachon University, Seongnam, Gyeonggi-do, Korea Abstract Phylogenetic analysis aims to produce a bifurcating tree, which disregards conflicting signals and displays only those that are present in a large proportion of the data. However, any character (or tree) conflict in a dataset allows the exploration of support for various evolutionary hypotheses. Although data-display network approaches exist, biologists cannot easily and routinely use them to compute rooted phylogenetic networks on real datasets containing hundreds of taxa. Here, we constructed an original neighbour-net for a large dataset of Asparagales to highlight the aspects of the resulting network that will be important for interpreting phylogeny. The analyses were largely conducted with new data collected for the same loci as in previous studies, but from different species accessions and greater sampling in many cases than in published analyses. The network tree summarised the majority data pattern in the characters of plastid sequences before tree building, which largely confirmed the currently recognised phylogenetic relationships. Most conflicting signals are at the base of each group along the Asparagales backbone, which helps us to establish the expectancy and advance our understanding of some difficult taxa relationships and their phylogeny. -

Changing to Apg Ii – THEORY PUT Into Practice for Over 100
SIBBALDIA: 133 The Journal of Botanic Garden Horticulture, No. 6 CHANGING TO APG II – THEORY PUT INTO PRACTICE Janette Latta1 ABstrAct In the summer of 2006, the Science Division at the Royal Botanic Garden Edinburgh made the decision to change the classification system used in their collections of pressed and preserved plants from the modified Bentham and Hooker system to that published by the Angiosperm Phylogeny Group (APG). As a result of that decision the Horticulture Division also decided to change its records and plant labels to the APG system. This paper describes the effect this had on the work of staff in both the Science and Horticulture Divisions as their collections had to be reorganized and relabelled to show the new family orders. IntroDuctIon For over 100 years the Herbarium of the Royal Botanic Garden Edinburgh (RBGE) had been organized according to the classification system of George Bentham and Joseph Hooker, with some modifications made over time. In summer 2006, staff in the Science Division held a full day seminar to discuss proposals to reclassify the Herbarium Collections according to the APG II system (wikipedia.org accessed 2 April 2008). It was felt that, as the institution was in the process of having an extension added to the Herbarium to add extra storage space, this was an opportune time, and possibly the only practical time, to effect the change. After the seminar a vote was held and the proposal was adopted. Work began to put this large, time-consuming and historically significant process in place in autumn 2006, with the database work being commenced from January 2007. -

Prof. Popov Str. 2, Russia, 197376. *author for correspondence Tupistra Ker Gawler (1814: 1655) belonging to Asparagaceae subfamily Nolinoideae (APG 2009, Chase et al. 2009), includes about 26 species (Govaerts 2016). These taxa spread mainly in south and south-east of continental Asia, including Nepal, Bhutan, India, Myanmar, China, Laos, Vietnam, Thailand and Malaysia (Tanaka 2003a, 2003b, 2010a, 2010b, Averyanov et al. 2016). This genus is characterised by leaves with slender petiolar base, relatively large stigma broader than the style, stout columnar style almost as thick as the ovary and usually tuberculate, dirty green, globular berry-like fruit (Tanaka 2003a, 2010a). In India, Tupistra is represented so far by four species, namely Tupistra clarkei Hooker (1894: 325), T. nutans Wall. ex Lindley (1839: 1223), T. stoliczana Kurz (1875: 199) and T. tupistroides (Kunth 1848: 12) Dandy (1932: 329). In course of the study of the genus Tupistra in India, a very distinctive species was found growing in the Garden of Botanical Survey of India, Eastern Regional Centre, Shillong, Meghalaya. It was overlooked during last decades and its origin could not ascertain as different species of plants growing in the garden are introduced from the diverse areas of north- eastern India. -

Analysis of the Flora
ANALYSIS OF THE FLORA The flora of the partially Himalayan district Darjeeling was not known properly. The area was surveyed by many stalwart floristic experts incliding Sir J.D. Hooker, Cambell, Griffith, Fr. Buchanan Hamilton, H. Hara, H. Ohashi, K.P. Biswas, D. G. Long, H.J. Noltie and many others. In recent years K.M. Matthew, A.P. Das and R.B. Bhujel and significantly contributing knowledge to the flora ofDarjeeling district. Even then a complete flora for the district was not available. Hills of Darjeeling and the places in Terai and Duars are well known and preferred spots for on field traing for the students of botany and forestry. R.B. Bhujel has presented the Dicotyledonous flora ofDarjeeling district in 1996 which is now in press for publication. The present work, the Monocotyledonous flora of Darjeeling will complete the angiospermic flora of this floristically extremely important district. The District of Darjeeling is a hugely populated place, though it has some quite well conserved, least interfered and even virgin places still rich in plant diversity. The most of the efficient reasons for development of such a rich floristic diversity of the region is its diversity in habitat structure, wide altitudinal ranges, unique and much variable climatic conditions, variation in adaphic and topographic conditions, high and widely distributed precipitation and the natural inter-relationship within the species. The Darjeeling region of the Eastern Himalaya has attracted a large number of tourists, botanists and naturalists from throughout the world at least for the last three centuries as it is floristically rich vegetation against the background of tallest Himalayan snow-covered peaks. -

Severtsov Institute of Ecology and Evolution of Russian Academy of Sciences, 33, Leninsky Pr., Moscow, Russia *author for correspondence Abstract Tupistra khangii (Asparagaceae) is described and illustrated as a new species from mountain areas in northern Vietnam. It is distributed widely in north-western Vietnam and adjacent territories. Key words: Tupistra khangii, Asparagaceae, plant taxonomy, plant diversity, Vietnam Introduction Tupistra Ker Gawler (1814: 1655) is a genus of the subfamily Nolinoideae (Chase et al. 2009) belonging to the family Asparagaceae (e.g. APG 2009). More than fifty species have hitherto been classified under Tupistra (IPNI 2014), but many of them were recently transferred to Rohdea Roth (1821: 196) by Tanaka (2003a, 2010a). Tupistra, as recircumscribed by Tanaka (2003b, 2010b), is distinguishable from Rohdea redefined by Tanaka (2003a, 2010a) by the leaves with more slender petiolar base, relatively larger stigma broader than the style, stouter columnar style almost as thick as the ovary, and usually tuberculate, non-scarlet, spherical berry-like fruit.
