In the scientific name Bambusa tulda, I would like to know what tulda (tuldus?) means.
Bambusa tulda Roxb.
synonym Dendrocalamus tulda (Roxb.) Voigt
In the Monaco Nature Encyclopedia, Giuseppe Mazza writes:
The name of the genus comes from the local Malay name “bambu”; the specific name is the local one, tulda bans, in Bengali language.
Roxb. refers to the botanist who listed the name:
Dr William Roxburgh FRSE FRCPE FLS (3 or 29 June 1751 – 18 February 1815) a Scottish surgeon and botanist known as the founding father of Indian botany. He sent many illustrations to Sir Joseph Banks, who in May 1795, started publishing Plants of the coast of Coromandel in 3 volumes with over 300 drawings and descriptions of plants. (Wikipedia)
