''Plantago debilis'' is a species of herb native to Australia. Common names include shade plantain and weak plantain. Description It grows as an annual or perennial herb up to 20 centimetres high, with green or white flowers and a slender taproot. Taxonomy This species was first published by Robert Brown in his 1810 '' Prodromus florae Novae Hollandiae''. In 1916 Joseph Maiden and Ernst Betche demoted it to a variety of ''Plantago varia, P. varia'', but this was not accepted. Two varieties have been published, but it is unclear whether they are still recognised. Plantago debilis var. parvifolia, ''P. debilis'' var. ''parvifolia'' was published as ''P. varia'' var. ''parvifolia'' by George Bentham in 1870. In 1937 Robert Pilger transferred it to ''P. debilis'', thus implicitly publishing the autonym (botany), autonym Plantago debilis var. debilis, ''P. debilis'' var. ''debilis''.

His contributions include one of the earliest detailed descriptions of the cell nucleus and cytoplasmic streaming; the observation of Brownian motion; early work on plant pollination and fertilisation, including being the first to recognise the fundamental difference between gymnosperms and angiosperms; and some of the earliest studies in palynology. He also made numerous contributions to plant taxonomy, notably erecting a number of plant families that are still accepted today; and numerous Australian plant genera and species, the fruit of his exploration of that continent with Matthew Flinders. Early life Robert Brown was born in Montrose on 21 December 1773, in a house that existed on the site where Montrose Library currently stands. He was the son of James Brown, a minister in the ...
