Aditya. This is I. d. var
This member of the Convolvulaceae
family was described by Carl Linnaeus in 1759. It is found in India
(Western Bengal State), Paraguay, Uruguay, Argentina
and on Mauritius, growing in forests. It prefers peat with quite some water and
not that much sun. The tuberous roots will grow to ten centimetres
in diameter, the vines to four meters in length. The flowers vary from pink to red. The plant can be reproduced both by seeds and
cuttings, both of which form a caudex.
It seems like it is
the same plant as some of the Ipomoeas from Paraguay, Uruguay, and
Argentina, which have been described later under other names.
