In 2002, the journal was published by the Department of National Parks, Wildlife and Plant Conservation with Prof. Dr. Thawatchai Santisuk as editor, supported by editorial board members from several prominent herbaria in Europe. At present, the TFB (Botany) is published by the Forest Herbarium in Bangkok, with Dr. Rachun Pooma and Dr. Tim Utteridge as editors. The journal is published once a year, usually in September-December with the manuscript no submission deadline, and articles are published in English. All manuscripts are peer reviewed by international scientists and edited by native English language speakers on the editorial board before acceptance and publication.&nbsp;TFB (Botany) will become both printed and electronic journal starting with volume 44 (2016), and through the TFB (Botany) Archive, every article published since 1954 is available and completely searchable online.</p> <p>ISSN : 0495-3843&nbsp;(print), 2465-423x (electronic)</p> https://www.tci-thaijo.org/index.php/ThaiForestBulletin/article/view/150087 Meizotropis (Leguminosae-Papilionoideae), a new genus record for Thailand 2019-01-18T14:15:09+07:00 Sakuntala Ninkaew sakuntalanin@gmail.com Charan Maknoi Charun@qsbg.org Wattana Tanming w.tanming@gmail.com Kongkanda Chayamarit kchayamarit@gmail.com Henrik Balslev henrik.balslev@bios.au.dk Pranom Chantaranothai chantaranothai@gmail.com <p><em>Meizotropis buteiformis</em> (Leguminosae), a new genus and species record for Thailand, is described and illustrated.</p> 2019-01-18T14:15:07+07:00 ##submission.copyrightStatement## https://www.tci-thaijo.org/index.php/ThaiForestBulletin/article/view/126560 Two new records and lectotypified taxa of the genus Millettia (Fabaceae: Millettieae) for Thailand 2019-01-18T16:24:49+07:00 Sawai Mattapha indigoferasawai@gmail.com Auamporn Veesommai Uvee_@hotmail.com Sathaporn Patthum kanor66na@gmail.com Pranom Chantaranothai chantaranothai@gmail.com <p>Two species, <em>Millettia penicillata</em> and <em>M. pierrei</em>, are recorded as new for Thailand.

Parnell jparnell@tcd.ie Trevor R. Hodkinson hodkinst@tcd.ie Pimwadee Pornpongrungrueng ppimwa@kku.ac.th <p>The pollen morphology of four genera and 33 taxa of Lecythidaceae in Southeast Asia was investigated, including 26 taxa of <em>Barringtonia</em>, one taxon each of <em>Careya</em> and <em>Chydenanthus</em>, and five taxa of <em>Planchonia</em> to determine which, if any, taxonomically important characters were present and the implications they have for the systematics of the family. Acetolysed and unacetolysed pollen samples were investigated using light and scanning electron microscopy (SEM). The pollen grains were found to be monads, radially symmetrical, isopolar, small to medium-sized, syntricolpate or syntricolporate, prolate spheroidal, oblate spheroidal, subprolate, suboblate or spherical in shape with marginal ridges. Marginal grooves and polar cushions are commonly present in most species. The polar ectoaperture may be open or sealed. The mesocolpial sculpturing is perforate-reticulate. The colpial surface is smooth, with sparsely or densely scattered verrucae-gemmae and with clavate to pilate elements scattered or aligned in longitudinal rows. The results indicated that pollen morphological characters can be used for identification and classification of some closely related species in the genus <em>Barringtonia</em>.</p> 2019-04-17T08:45:30+07:00 ##submission.copyrightStatement## https://www.tci-thaijo.org/index.php/ThaiForestBulletin/article/view/124982 Drimia indica (Asparageceae, Scilloideae), a new record for Thailand 2019-05-31T14:29:31+07:00 Sunanta Wisittipanich swisittipanich48@gmail.com Santi Saraphol santi13301@hotmail.com <p><em>Drimia indica</em> is newly recorded for Thailand.

Saunders saunders@hku.hk Piya Chalermglin piya.chalerm@gmail.com Tanawat Chaowasku craibella@hotmail.com <p>We review the species diversity of the Asian genus <em>Meiogyne</em> (Annonaceae) in Thailand. Four new species, <em>M. anomalocarpa</em>, <em>M. chiangraiensis</em>, <em>M. gardneri</em>, and <em>M. maxiflora</em>, are described. <em>Meiogyne anomalocarpa</em> has the widest distribution of any <em>Meiogyne</em> species in Thailand, but the other three species are narrowly distributed. <em>Meiogyne anomalocarpa</em> and <em>M. maxiflora</em> have the axillary inflorescences typical of the genus, but in <em>M. chiangraiensis</em> and <em>M. gardneri</em> the inflorescences are flagelliform and arise from the lower trunk, a morphology previously unreported from members of this genus. The presence of <em>M. chiangraiensis</em> in northern Thailand extends the range of the genus significantly northward. <em>Meiogyne caudata</em> is reported as new to the flora of Thailand. Several <em>Meiogyne</em> specimens from southernmost Thailand previously identified as <em>M. virgata</em> in the past by various workers were found to be more similar to <em>M. kanthanensis</em>, recently described from Perak, Peninsular Malaysia. A key is provided for the eight species currently recognized as occurring in the country.</p> 2019-06-12T00:00:00+07:00 ##submission.copyrightStatement## https://www.tci-thaijo.org/index.php/ThaiForestBulletin/article/view/137692 The genus Calycularia (Calyculariaceae, Marchantiophyta) in Thailand 2019-06-12T15:35:56+07:00 Narin Printarakul kamenpcobtor@gmail.com Phiangphak Sukkharak phiangphak@buu.ac.th Sahut Chantanaorrapint sahut.c@psu.ac.th <p>A taxonomic study of the genus <em>Calycularia</em> in Thailand is presented, based on herbarium specimens and field surveys.
