Abstract

The genus Rohdea Roth (1821: 196) belonging to the family Asparagaceae (APG 2009) comprises 14 species and is distributed in South East Asia (Tanaka 2003, Averyanov et al. 2014, Govaerts 2016). In India, the genus includes 4 species namely R. delavayi (Franchet 1896: 40) Tanaka (2003: 331), R. eucomoides (Baker 1875: 581) Tanaka (2003: 332), R. nepalensis (Rafinesque 1838: 15) Tanaka (2010: 23) and R. wattii (Clarke 1889: 78) Yamashita & Tamura (2004: 369) (Hooker 1894, Liang & Tamura 2000).

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.…”
