Type.

A cultivated plant ex Herb. Collins (not found).

Diagnosis. This is the garden hybrid Ipomoea quamoclit × coccinea , which was originally grown as long ago as the 1830s (Rafinesque 1838b). It is known as Cardinal Climber and can be recognised by its deeply palmately-pinnatifid leaves and red flowers resembling Ipomoea coccinea more than I. quamoclit . It is more vigorous than either of the two parent species.

Distribution.

Although Rafinesque suggested it sometimes grew spontaneously, there are no other reports that this hybrid grows outside gardens. The following are records of cultivated plants:

UNITED STATES. Missouri: G. Engelmann (K). New York: Ithaca, W.J. Dress 1199 (BM).

Note.

The name Ipomoea × sloteri is generally used for this hybrid but there seems no reason why the older Ipomoea × multifida should not be adopted.
