to add, that we proceed no further with those modern 
writers whom we follow in this particular, and that, on the 
contrary, we are persuaded that the group now formed 
by the union of Ipomea and Convolvulus contains, within 
itself, the rudiments of more than one well-marked genus, 
besides the Callistegia of Mr. Brown, the Argyreia of Lou- 
reiro, or Lettsomia of Roxb., and the Dufourea of Kunth. 
Stem annual, twining, round, smooth, as are all the 
parts, except the young shoots, which are slightly downy. 
Leaves smooth, sometimes 3-lobed, deeply cordate, acu- 
minate, sometimes entire, roundish-cordate, acuminate. 
Peduncles many-flowered, shorter than petioles. _ Calyves 
leafy, smooth; their sepals much shorter than the co- 
rolla. Corolla of a beautiful rose colour, with a sub- 
cylindrical inflated tube, and a spreading 5-toothed limb, 
shorter than the tube. Stigma capitate, 2-lobed, about the 
Jength of stamens, —
