In this treatment, 21 species are recognized; 14 names are lectotypified (<em>B. argentata</em>, <em>B. balansae</em>, <em>B. balansae</em> var. <em>muticarpa</em>, <em>B. clarkei</em>, <em>B. elegantissima</em>, <em>B. ferruginea</em>, <em>B. globularia</em>, <em>B. glomerata</em> var. <em>tonkinensis</em>, <em>B. lucidula</em>, <em>B. obovalifoliosa</em>, <em>B. palembanica</em>, <em>B. poilanei</em>, <em>B. sphaerocarpa</em> and <em>B. wightii</em>), five names are placed into synonymy for the first time, and <em>B. laotica</em> Kosterm. ex de Kok is validly published here for the first time. In addition, one new variety (<em>B. percoriacea</em> var. <em>percoriacea</em> de Kok) is proposed and one new combination (<em>B. percoriacea</em> var. <em>glaucoides</em> de Kok) is made. Nine species are considered to be Least Concern, one is Critically Endangered, five are Endangered, and five are listed as Vulnerable.</p> 2021-02-01T14:57:20+07:00 Copyright (c) 2021 Forest Herbarium https://li01.tci-thaijo.org/index.php/ThaiForestBulletin/article/view/247768 Taxonomic notes on the Rutaceae of Thailand 2021-02-02T13:05:47+07:00 Hans-Joachim Esser esser@snsb.de <p>Nomenclatural problems with the name of <em>Atalantia simplicifolia</em> are discussed, and it is shown that the, often used, name of <em>A. roxburghiana </em>is illegitimate. <em>Bergera</em> is established as separate genus for Thailand, formerly part of <em>Murraya</em>. <em>Murraya siamensis</em> is established as a synonym of <em>Bergera koenigii</em>.&nbsp;</p> 2021-02-02T13:05:46+07:00 Copyright (c) 2021 Forest Herbarium https://li01.tci-thaijo.org/index.php/ThaiForestBulletin/article/view/247083 Curcuma lithophila and C. rufostriata (Zingiberaceae), two new species from Thailand, and additional notes on C. papilionacea 2021-02-06T15:43:06+07:00 Sutthinut Soonthornkalump s_soonthornkalump@hotmail.com Tidarat Pungpairote tidarat.pu@psu.ac.th Sira Niwesrat s_soonthornkalump@hotmail.com Jana Skornickova jana_skornickova@seznam.cz <p><em>Curcuma lithophila</em> and <em>C. rufostriata</em>, two new species from <em>Curcuma</em> subgen. <em>Hitcheniopsis</em>, are described and illustrated.
