The Forest Herbarium (BKF; Thai: หอพรรณไม้) is the herbarium of the Department of National Parks, Wildlife and Plant Conservation of Thailand, in Bangkok.[1] The Royal Forest Department set it up in 1930 to keep the specimens from its plant surveys.[2] In August 2018 it held about 300,000 preserved specimens, mainly of flowering plants and ferns collected in Thailand.[3] Its specimen database lists 25 sheets of Cannabis, collected between 1933 and 1999.[4]
History
The herbarium's own history dates the Royal Forest Department's plant collecting to 1906 (B.E. 2449). The British forest officer H. B. G. Garrett was in charge, and the early surveys concentrated on plants of economic value. In 1930 (B.E. 2473) the department assigned Phraya Winit Wanandon to establish a herbarium formally, to keep the specimens from its surveys.[2] Thawatchai Santisuk's editorial for the herbarium's 80th anniversary gives the same year. It places the founding ten years after that of the Bangkok Herbarium (BK) of the Department of Technical Agriculture, and names Phraya Winit Wanandon as the first director.[5] Index Herbariorum gives 1905 as the founding year.[1]
The herbarium later passed from the Royal Forest Department to the Department of National Parks, Wildlife and Plant Conservation, which was inaugurated in 2002.[6][7] The herbarium's Thai timeline dates the transfer to B.E. 2546 (2003). The unit has been renamed several times since. In July 2026 it became the Forest Botany Division (ส่วนพฤกษศาสตร์ป่าไม้) of the department's Forest and Plant Conservation Research Division.[2] It occupies the second to fifth floors of the Natural History Museum building at 61 Phahonyothin Road, Chatuchak.[2][8]
Collections and work
The herbarium conducts botanical inventories and taxonomic research for the Flora of Thailand project. It also surveys and classifies Thai forest types and supervises the country's botanical gardens and arboreta.[3] It publishes the journal Thai Forest Bulletin (Botany), first issued by the Royal Forest Department in 1954.[9][10] Its database lists 956 type specimens.[4]
The collections include those of Garrett, who collected in northern Thailand between 1899 and 1959, and of the forest officer Phraya Vanprueck Phicharn, who collected between 1912 and 1920. They also include the collections of Khid Suvarnasuddhi from 1936 to 1942 and of Tem Smitinand from 1947 onwards. Between 1947 and 1977 Smitinand organised a group of Thai collectors to explore different parts of the country. A. F. G. Kerr, who collected in Thailand between 1902 and 1932, deposited his complete set at Kew and the British Museum.[11]
Cannabis in the Flora of Thailand
Chamlong Phengklai's treatment of the hemp family, then called Cannabidaceae, appeared in volume 2, part 4 of the Flora of Thailand in 1981. It records Cannabis sativa as the family's only representative in Thailand, grown under cultivation.[12] The species account gives its range in Thailand as "Northern, North-Eastern and Central: cultivated only". The account gives the vernacular names กัญชา (kancha) and, in central Thailand, กัญชาจีน (kancha chin). It records two uses: fibre from the stems of male plants for rope and textiles, "especially Hill-Tribes in northern Thailand", and the leaves of female plants smoked as a drug.[13] The later account of the Cannabaceae in volume 13, part 1 (2015) refers Cannabis back to the 1981 treatment.[14]
Cannabis specimens

The specimen database lists 25 Cannabis sheets under 19 accession numbers, none of them type material. Twenty-four are from Thailand. The other, Banerjee 263 (1964), was collected by S. P. Banerjee at Motihari, in India, in 1964.[4] The sheets include Garrett 851 (1933) and Garrett 852 (1933), both collected by Garrett on 2 December 1933. They also include five sheets of Suvannasuddhi 457 (1940), a single gathering made at the Forestry School in Phrae on 1 August 1940.[4] A sheet collected by P. Suvarnakoses at Khiri Wong in Nakhon Si Thammarat on 16 December 1951 describes the plant as a crop in a garden, "Used for smoking".[15]
