Journal of the Arnold Arboretum 3: 210 (1920)

Rosa omeiensis f . chrysocarpa, forma nov.

A typo recedit fructu luteo majore. — Frutex ramis aculeis basi valde dilatatis armatis, turionibus insuper dense aciculate-setosis: folia ramulorum pleraque 5-juga, turionum 6-7-juga foliolis glabris; fructus stipite carnoso parti superiori subaequilongo incluso circiter 2 cm. longus et 11-12 mm. diam.

Raised from seed sent from western China by E. H. Wilson to the Arnold Arboretum in 1908 or 1910; specimens collected in Hort. H. S. Hunnewell, Wellesley, Massachusetts, by Mrs. S. D. McKelvey, August 8, 1922. (type).

This form differs in its bright yellow fruits from typical R. omeiensis Rolfe which has the fruits entirely red or sometimes red with the stalk-like stipe colored orange. The lighter and brighter color of the larger fruits makes this form even more conspicuous at fruiting time than the red-fruited type, though unfortunately the fruit of R. omeiensis which ripens early in July and a month later in the yellow-fruited form drops soon after ripening and therefore the display does not last long.
