Caulokaempferiasirirugsae sp. nov. (Zingiberaceae) from southern Thailand

Abstract

A new species of Caulokaempferia from southern Thailand, C. sirirugsae Ngamriab. is described and illustrated. The new species is morphologically similar to C. saksuwaniae, from which it differs by having large flying rhombic staminodes, ovate anther crest, obovate labellum and untoothed acuminate calyx tip.

A new species and two new combinations of Monolophus (Zingiberaceae) from Indo-Burma

“…Recently, the genus Monolophus was reinstated by Mood et al (2014) with 22 new combinations. So far, the genus consists of 33 species (Larsen and Smith 1972;Larsen 1973Larsen , 2002Larsen and Jenjittikul 2004;Suksathan and Triboun 2004;Picheansoonthon and Mokkamul 2006;Ngamriabsakul 2008;Tiyaworanant 2010;Chaturvedi et al 2012;Roy and Barbhuiya 2013;Intharapichai et al 2014;Mood et al 2014;Phokham et al 2015a, b;Sangnark et al 2016;Veldkamp 2016;Bhaumik et al 2017;Barbhuiya et al 2018;Douangdeuane et al 2019) from the Himalayas to South East Asia. There are two distinct groups, the yellow-flowered species (~28 taxa) that are distributed in Thailand and adjacent countries and the other non-yellowflowered species (purple, red-purple, pink and white) (~5 taxa) which are localized in Eastern Himalaya (Bhaumik et al 2017).…”

Editorial

“…Second largest is India with 11 recent contributions (Banik and Sanjappa 2008, Baruah and Nath 2008, Raole and Desai 2008, Viswanathan and Manikandan 2009, Kandwal and Gupta 2010, Karthigeyan et al 2010a, 2010b, Pusalkar and Singh 2010, Sujanapal and Sasidharan 2010, Tandyekkal and Mohanan 2010, Yadav et al 2010), but we have also published numerous significant contributions to our knowledge of the plant biodiversity of southeastern-most Asia, i.e. Vietnam (Orel and Wilson 2010, Trân and Leong-Skorniková 2010, Vu and Xia 2010, Thailand (Ngamriabsakul 2008), the Indonesian-Malesian region (Turner and Saunders 2008, Vermeulen 2008, Tang et al 2010, Turner 2009 and Oceania (Wilmot-Dear and Friis 2010). Several of these contributions deal with genera and families well known to be unique and characteristic components of the Asiatic flora.…”

“…Several of these contributions deal with genera and families well known to be unique and characteristic components of the Asiatic flora. Thus, in the last three issues, four new taxa of bamboos have been described (Zhang et al 2008, Guo et al 2010, Trân et al 2010, Zhang and Li 2010), five new taxa of Magnolia and closely related genera (Yi et al 2008, Dong et al 2009b, Liao and Xia 2009, Liu et al 2009, Vu and Xia 2010), three new Rhodondron taxa (Jin et al 2009a,b, Chen et al 2010) and three new species of Zingiberaceae (Ngamriabsakul 2008, Li et al 2009, Sujanapal and Sasidharan 2010). It is also noteworthy that no less than six new taxa of the genus Impatiens have been discovered (Jin et al 2008, Bi et al 2009, 2010, Dong et al 2009a, Cong et al 2010).…”

The evolution of a new scene for botanical publication from the Nordic countries

“…It is therefore most encouraging to see that almost 100 new taxa from throughout the world was published in 2008. Most novelties are vascular plants from Turkey (Aksoy et al 2008, Dogan et al 2008, Dönmez 2008, Eker and Koyuncu 2008, Gemici et al 2008, Ilçim 2008, Ilçim et al 2008, Teksen and Aytaç 2008, Uysal 2008, Yaprak and Yurdakulol 2008, Zielinski and Tomaszewski, 2008), Iran (Hamdi et al 2008, Pakravan 2008, Khosravi and Poormahdi 2008, Ranjbar et al 2008), India (Baruah and Nath 2008, Raole and Desai 2008), China (Cong et al 2008, Gao and Zhang 2008, Häkkinen and Wang 2008, Jiang and Liu 2008, Jin et al 2008, Li and Wang 2008, Lidén and Van De Veire 2008, Qiao and Zhang 2008, Shi et al 2008b, Song et al 2008, Tian et al 2008, Wang et al 2008, Wei et al 2008, Xiang and Peng 2008, Xiang et al 2008, Yi et al 2008, Zhang and Li 2008, Zhang et al 2008a,b,c, Zhou et al 2008a) and south east Asia (Ngamriabsakul 2008, Turner and Saunders 2008), demonstrating the botanical richness and the great need for basic taxonomic research in these regions. For example, in one single paper, Vermeulen (2008) described 38 new species of the orchid genus Bulbophyllum from New Guinea alone.…”
