Rosa setipoda AAEE   Rosa corymbulosa EE ?
Hurst diagnosed Rosa corymbulosa as EE. However, the styles and clusters of this specimen suggest influence from a Synstyle (AA). It was raised from seeds "collected in Western China in Autumn 1907, under the field-number 630A, by Mr. E. H. Wilson." In addition, Wilson (1916) wrote, "The wild plants have usually much smaller corymbs than that figured by Rolfe, indeed the flowers are often solitary."
