Syringa vulgaris ultimately for the plants, was Pietro Andrea Mattioli, as one can tell from a unique copy of Tradescant's plant list in his Lambeth garden, an adjunct of his "Musaeum Tradescantianum"; it was printed, though probably not published, in 1634: it lists "Lilac Matthioli". That Tradescant's "lilac of Mattioli's" was a white one is shown by Elias Ashmole's manuscript list, "Trees found in Mrs Tredescants Ground when it came into my possession" (1662): "Syringa alba". In the American colonies, lilacs were introduced in the 18th century. Peter Collinson, F.R.S., wrote to the Pennsylvania gardener and botanist John Bartram, proposing to send
Flowering plant The APG system of 1998, and the later 2003 and 2009 revisions, treat the flowering plants as a clade called angiosperms without a formal botanical name. However, a formal classification was published alongside the 2009 revision in which the flowering plants form the Subclass Magnoliidae. The internal classification of this group has undergone considerable revision. The Cronquist system, proposed by Arthur Cronquist in 1968 and published in its full form in 1981, is still widely used but is no longer believed to accurately reflect phylogeny. A consensus about how the flowering plants should be arranged has recently begun to emerge
