Tupistra ashihoi (Asparagaceae), a new species from north-eastern India

Abstract

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).

New contributions to the flora of Myanmar Ⅰ

“…Tupistra natmataungensis also shares similarity with Tupistra khasiana D.K. Roy, A.A. Mao & Aver (Roy et al., 2017), both of them with creeping rhizomatous stem and short spike, but the later with broadly oblanceolate leaves (vs. linear leaves), 5–7-flowered (vs. c. 3-flowered), perianth lobes light green externally (vs. yellow-orange with purple-red spots), stigma dark purple (vs. yellow-orange), which allows it to be easily distinguished from the new species.…”

New species of Peliosanthes, Rohdea and Tupistra (Asparagaceae) from Laos and Vietnam

“…Within Asia, Peliosanthes and Tupistra occur mainly in subtropical to tropical regions (Jessop 1976, Tanaka 2010a, and Rohdea in warm temperate to subtropical regions (Tanaka 2010b). Taxonomic studies on these genera in subtropical or tropical regions have been conducted by many botanists (Baker 1879, Hooker 1892, Ridley 1898, 1924, Rodriguez 1934, Larsen 1966, Jessop 1976, Tanaka 1999, 2003a, 2003b, 2003c, 2004a, 2004b, 2010a, 2010b, 2010c, 2010d, Shaw 2009, Averyanov 2011, Averyanov and Tanaka 2012, 2013, 2014, 2015a, 2015b, 2016a, 2016b, Vislobokov 2016, Nguyen et al 2017, Odyuo et al 2017, Roy et al 2017. Their results mostly included the discovery of new taxa.…”
