A NEW HYBRID CHERRY, PRUNUS x PUGETENSIS (P. AVIUM x P. EMARGINATA, ROSACEÆ), FROM THE PACIFIC NORTHWEST

    The article A New Hybrid Cherry . . . co-written by Arthur Lee Jacobson and Peter F. Zika, was published in the scholarly botanical journal MADROÑO, Volume 54, Number 1, pages 74-85. The article gave details on the following abstract:

    A natural hybrid, Prunus xpugetensis A. L. Jacobson & Zika, is described as the cross between introduced Prunus avium (L.) L. of Eurasia, and indigenous P. emarginata (Douglas ex Hook.) Eaton of western North America. It is intermediate in morphology, differing from P. avium in its pubescence, more slender leaves, smaller flowers, and peduncled inflorescences. It can be separated from P. emarginata by its broader leaves with coarser teeth, larger flowers with weakly notched petals, and occasional umbellate inflorescences. Unlike the parents, more than 99% of the flowers eventually abort and it rarely produces fruit. Spontaneous hybrids have been found in the lowlands of western British Columbia, Washington, and Oregon.
