54307-54323 Bronx, New York Botanical Garden. Voucher for a leaf tissue and DNA sample collected for the New York Botanical Garden Forest DNA Barcoding Project; funded by the Alfred P. Sloan Foundation.

54307 Rosaceae Prunus virginiana L.

det. M. Nee, 2006

Presumably native shrubs, 3 m. tall, to 4 cm. in diameter. In woods of Prunus serotina, Quercus rubra on slope between Pfizer Lab and upper Twin Lake. Inflorescence hanging or nodding to nearly horizontal. Flowers lightly fragrant; petals white; filaments white; anthers light yellow.

A very similar cultivated ornamental shrub (Nee 54306) from a few blocks away differs from this native P. virginiana at the New York Botanical Garden by all the flower parts being larger, the inflorescence shorter and more crowded, with the flowers contiguous rather than slightly separated, and by having ca. 40 instead of ca. 20 stamens.
