Although the Coronopus-leaved Cantua was cultivated in Sherard’s celebrated garden at Eltham, in the time of Dillenius, and is figured by him, in the _Hort. Elth._ above cited, as a species of _Quamoclit_, it has been an entire stranger to our modern gardens until very lately; having no doubt long since perished in all the old collections. Who the reintroducer of this very elegant plant is, we have yet to learn: but the beautiful specimen here figured, was obligingly communicated to us by the Marquis of Blandford, from White Knights, Berks, about the end of November last. It is a native of Carolina, and sufficiently hardy, we should think, to resist the cold of our ordinary winters: its root is herbaceous, and the plant admits of increase by parting the same, in spring or autumn. Writers have differed in a very remarkable manner concerning the Genus to which they should refer this plant; and Linnæus himself seems to have been as undetermined as any of them concerning it; having at different times given it as a _Polemonium_, and an _Ipomea_; as will appear among our synonyms above. Michaux has called it _Ipomopsis_: and another foreign writer, whose work we have not got, has given it the appellation of _Noothea Pulchella_: but Willdenow has added it to the genus _Cantua_, with which we conceive, in our humble opinion, it sufficiently accords; and have therefore ventured to follow him in his arrangement of it.
