Abutilon and Hibiscus "bigener"

Dr. M. T. Masters described a very dark flowered Abutilon which was said to be due to an original cross between Hibiscus Rosa sinensis and Abutilon striatum. The original plant was a dark flowered seedling, which was fertilized by Mr. George for two or three generations with the pollen of the Hibiscus, and though the character of the flower is that of an Abutilon, it has the truncated column and foliage of Hibiscus. In one plant the leaves were blotched with a dark crimson spot. Hence it is probably a true bigener, or case of generic crossing.
