John Lindley - Middle Years

Middle Years

An eminent botanist of the time, John Claudius Loudon, sought Lindley’s collaboration on his “Encyclopedia of Plants”. This covered nearly fifteen thousand species of flowering plants and ferns. It was a massive undertaking and Lindley was responsible for most of it.

During his labour on this undertaking, which was completed in 1829, and through arduous study of character patterns, he became convinced of the superiority of the "natural" classification system devised by Antoine Laurent de Jussieu – a system that he believed reflected the great plan of nature as distinct from the "artificial" system of Linnaeus followed in the Encyclopaedia of Plants. This conviction found expression in A Synopsis of British Flora, arranged according to the Natural Order (1829) and in An Introduction to the Natural System of Botany (1831).

In 1828 Lindley was elected a fellow of the Royal Society of London and in 1833 was awarded the honorary degree of Doctor of Philosophy from the University of Munich. Other honours came from France, the United states and Switzerland.

In 1829 Lindley sought to augment his income and became professor of botany at the newly established London University while still continuing his post at the Royal Horticultural Society. He had not been to university himself but apparently was an excellent teacher, giving six hour-long lectures each week. Being dissatisfied with what was available, he wrote some botanical textbooks for his students.

After the death of Joseph Banks and the death also of their patron, King George III, the Royal Botanic Gardens at Kew went into a decline. The Government commissioned a report on their future to be prepared by Lindley, Joseph Paxton and John Wilson, head gardener to the Earl of Surrey. The report recommended that the Gardens be retained but the Government did not accept their findings and proposed to abolish it, distribute the plants and pull down the glasshouses. On 11 February 1840, Lindley told the Prime Minister that the matter was to be raised in Parliament. This caused an outcry. The public was indignant, the Government backed down and the Gardens were saved. William Hooker was appointed to be the new Director.

In 1845, Lindley was part of a scientific commission set up by the Government to investigate potato blight and the Irish famine. The cause of the fungal disease was not known at the time and the weather was thought to be to blame. Although the commission was powerless to solve the problem, their report brought about the repeal of the 1815 Corn Laws which had forbidden the import of cheap wheat from America. This helped to alleviate the effects of the disease on populations that had become reliant on the monoculture of potatoes. He was elected a Foreign Honorary Member of the American Academy of Arts and Sciences in 1859.

Lindley was very industrious and hardworking and published a number of works including ‘’The Genera and Species of Orchidaceous Plants’’, the writing of which occupied him for ten years. He was acknowledged to be the top authority on the classification of orchids of his time. Bentham and Hooker, writing in 1883, accepted 114 genera he had named and described, and Pfitzer, in 1889, accepted 127. Over many years, Lindley had described a large number of orchid species, and many other plants, naming them and giving each a concise description of the plant’s characteristics.

He was held in high regard by other botanists and was honoured by the creation of a large number of species with the epithets “lindleyi”and “lindleyanus”.
