THE Thunbergia, here figured, is a native of the Eaft Indies, from the Coromandel coatl:; was introduced
to Britain in the year l/g6, at the fame time with the Ixora pavetta, by the Hon. Lady Dowager
De Clifford. It is eafily propagated, by cuttings, or from the feeds, which ripen with us: it
iTiould be kept in light, rich earth in the hothoufe; where it will flower from May, till September;
in which month this year our drawing was taken at Kenfington Gore from a plant in the colleftion
of James Vere, Efq. But although Dr. Roxburgh's reafon for adopting the fpecific chara£terhe has
given it, that the place where it grows is fweet fcented, though the plant is not, feems rather a little
ftrained, we have not thought it right to alter it; as unqueftionably, any name would have been equally
appropriate, fince neither the flowers, or any part of the plant, root or branch, has the leaft fcent.
The plant from which this genus was originally formed by the younger Linnaeus in his Sup. Plant.
P. 46, is a native of the Cape of Good Hope; and we have our doubts, whether this plant ought to
be placed with it; for although it accords in the eflTential character, of a double cup, the only one
thought necefl"ai7', by Linnaeus, to divide it from Barleria ; yet, from the number of parts in which
it differs from his generic charafter, fuch as the ihape of the blofi"om, the length of the pointal, the
fituation and ihape of the chives, the very different lhape of the feeds, &c. we are led to think, it
ought to be confidered as a diftinft Genus. But in following fuch good authority as the able and
learned Dr. Roxburg, it is to be hoped, we iliall iland excufed in continuing the fame name he has
afljgned it, witliout alteration at leaft, if not without comment.
