Johannes Elias Teijsmann (1 June 1808 – 22 June 1882) was a biologist,

botanist and plant collector. He was born in Arnhem
, The Netherlands. His surname is sometimes spelled Teysmann, although he spelled it Teijsmann.

Teijsmann travelled to

Siam (presently Thailand).[1]

He is notable for the introduction of

oil palm (from West Africa) to Indonesia, which remains a significant export earner for the country’s economy. He also introduced vanilla artificial pollination techniques to Java, making the crop much more productive and cheaper.[4] Due to Teijsmann's hard put effort the number of plant collections in the garden had grown from 900 in 1822 to 10,000 in 1863.[5]

Teijsmann also played a large role in the separation of the Botanic Gardens from the adjacent Buitenzorg Palace on 30 May 1868, a move that gave the public and scientists more access to the Gardens.[6] He resigned honorably from the directorship of the garden in 1869 and was awarded the title "Inspector Honorair Cultures". Using this title he visited many of the provincial residences across the Dutch East Indies and continued to gather more plants for the Botanical Gardens.[5]

Teijsmann died in 1882 and for his service to Lands Plantentuin, a monument to honor him was erected by the Gardens' director Dr. Melchior Treub , and his friends in 1884. The monument is located in what is now called the Medan Teijsmann in the Botanic Garden (now known as Kebun Raya Bogor).[6]

The genus

Teysmannia (since the work of Harold Emery Moore more correctly called Johannesteijsmannia
) is named in his honour, together with several plant species. He was also commemorated in the periodical Teysmannia, which was published between 1890 and 1922. In 1925, it was incorporated into De Indische Culturen-Teysmannia.

The standard author abbreviation Teijsm. is used to indicate this person as the author when citing a botanical name.[7]
