Polyploid speciation in hybrid morning glories of Ipomoea L. sect. <i>Quamoclit</i> Griseb. [link]Paper  doi  abstract   bibtex   
Diploid artificial hybrids between Ipomoea coccinea L. and I. quamoclit L. produced eight seeds in a sample of 280000 ovules. The resulting F2 plants were tetraploid and fertile. Polyploidy probably occurred through the union of two unreduced gametes. The F2 plants appear reproductively isolated from their F1 parents and from the progenitor species. This cross recreates the cardinal climber, I. sloteri (House) van Ooststr., a culivated species thought to have arisen originally from a single seed.
