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://li01.tci-thaijo.org/index.php/ThaiForestBulletin/article/view/247905 Obituary: Prof. Dr Thawatchai Santisuk (1944–2020) 2020-11-18T14:22:24+07:00 Kongkanda Chayamarit kchayamarit@gmail.com David A.

Grote pauljosephgrote@yahoo.com <p>The Cenozoic palaeovegetation and palaeoclimate of Doi Ton, western Thailand, megaflora are reconstructed based on physiognomic climate analysis, including Leaf Margin Analysis (LMA), Leaf Area Analysis (LAA), Leaf Size Index (LSI), Climate Leaf Analysis Multivariate Program (CLAMP), and systematic descriptions of each leaf morphotype. The leaf fossils were divided into 23 dicotyledonous leaf morphotypes and two unknown leaf morphotypes. The mean annual temperature results from LMA indicate 32.3 ± 1.17 °C and CLAMP shows 21.2°C. CLAMP also provides temperature data of a warm month mean temperature (WMMT) of 27.4 °C and a CMMT of 14.2 °C, which is similar to the present climate. The mean annual precipitation is estimated by LAA to be ~ 125 cm. CLAMP suggests precipitation in the 11 months of growing period was 154.9 cm with the three wettest months having precipitation of 73 cm, widely contrasting with 15.5 cm for the three driest months. The precipitation shows the signal of the monsoon effect. The temperature, precipitation, and LSI mirrored the vegetation of the contemporary Doi Ton area which is a semi-evergreen forest in the tropical zone. The palaeoclimatic parameters of Doi Ton are in good agreement with those of south China and northwest<br>India from the Eocene period and the present-day Mae Sot area. Moreover, the Doi Ton flora also closely matches the humid subtropical modern vegetation of south China. Palaeoclimate and vegetation analysis support an Eocene age estimate for the Doi Ton Formation however further independent age estimates are required to test this working hypothesis.</p> 2020-08-03T16:42:45+07:00 Copyright (c) 2020 Forest Herbarium https://li01.tci-thaijo.org/index.php/ThaiForestBulletin/article/view/242818 Notes on the typification of five names in Lauraceae 2020-08-22T10:15:23+07:00 Anand Kumar anand_kum234@rediffmail.com <p>This article deals with inadvertent lectotypifications of five names in the Lauraceae, <em>Cryptocarya densiflora</em>, <em>Cryptocarya impressa</em>, <em>Cylicodaphne infectoria</em>, <em>Laurus cubeba</em> and <em>Litsea castanea</em>, that have been previously overlooked.</p> 2020-08-22T10:15:22+07:00 Copyright (c) 2020 Forest Herbarium https://li01.tci-thaijo.org/index.php/ThaiForestBulletin/article/view/177131 A synopsis of Thai Piper (Piperaceae) 2020-08-31T15:38:46+07:00 Chalermpol Suwanphakdee fscicps@ku.ac.th David A.
