Thomas Drummond (botanist)

Thomas Drummond (1793[1] — March 1835), was a Scottish botanical collector.

Thomas Drummond


Thomas Drummond was the younger brother of the botanist James Drummond. He was born in Scotland, and during the early part of his life was at Don's nursery, Forfar. He first became known to botanists by his distributed sets of mosses, ‘Musci Scotici,’ and afterwards was attached as assistant-naturalist to Dr. Richardson in Sir John Franklin's second land expedition.

He accordingly sailed from Liverpool on 16 February 1825 and reached New York on the 15th of the following month. The expedition moved westward by the Hudson River and lakes Ontario and Winnipeg to the Mackenzie River. Drummond quit the main party at Cumberland House to explore the Rocky Mountains.

On 3 June 1827 Drummond met David Douglas at Carlton House as Douglas was venturing overland from Fort Vancouver toward York Factory, Manitoba on his return trip to London, collecting for the Royal Horticultural Society.

In the spring of 1831 Drummond journeyed on foot by the Alleghany Mountains, reaching St. Louis in July, where he fell ill. In consequence of this delay he was unable to join the fur traders on their expedition to the north. He therefore was compelled to confine his explorations to New Orleans and thereabouts. Hence he made a botanical tour in Texas; at Velasco an attack of cholera prostrated him, but on recovering he continued his labours. Drummond collected along the Brazos, Colorado and Guadalupe Rivers, spending almost two years collecting plants and birds in Texas. His plant specimens from Texas were widely distributed in Europe and stimulated later botanical exploration. (Geiser, 1949) He embarked finally for Havana on 9 February 1835 and died at that port early in March. The plants sent home by Drummond were described by Sir William Hooker in his Flora Boreali-Americana, his Journal of Botany, and Companion to the Botanical Magazine.

He and his brother, James are honoured in 1855,[2] in the Australian plant genus of Drummondita (in the Rutaceae family).[3]
