to lose the ability to produce a greater amount of acylated antho-
cyanins, it appears that they should cluster with these members.
Yet, because the two species and are distributed through the
mountains of the southwestern region of Yunnan Province along
the Nujian River, and because they possess relatively a higher
amount of 3GX- and 3GaX-types of anthocyanins than other spe-
cies, these two species are thought to be the progeny of C. reticulata
and/or C. pitardii var. yunnanica. The data suggest that they not
only lost the ability to produce the acylated anthocyanins but also
lost the tendency toward 20
-O-xylosylation as they spread down
the Nujiang River.
