R. sericea f. chrysocarpa Rehd.
R. sericea is variable in the colouring of its fruits. The commonest colour is bright red or scarlet (often yellow with a yellow foot-stalk in var. omeiensis). But they may be wholly yellow (f. chrysocarpa Rehd.) ; R. omeiensis f. chrysocarpa Rehd....
or dark purplish red ( f. atropurpurea (A. Osborn); R. omeiensis var. atropurpurea Rolfe ex A. Osborn).

Rosa sericea Lind. and R. omeiensis Rolfe Hurst's hybridisations and living material now in the National
Rose Species Collection at Bayfordbury suggest that these two are best united as a single species under the older name R. sericea LINDL. Parallel variations, like the pteracantha prickle form, occur in both, and all combinations of leaflet number, dentition, pedicel form and so forth. A key follows to the better subdivisions:
Fruit red:
--Plant unarmed . . . . . . . . . . . . . . . . . . . . . . . . . . . var. denudata.
--Plant with prickles and bristles:
----Leaflets numerous, up to 17 . . . . . . . . . . . . . . . var. polyphylla.
----Leaflets rarely more than 11 :
--------Pedicels slender, green . . . . . . . . . . . . . . . . var. sericea.
--------Pedicels fleshy, red . . . . . . . . . . . . . . . . . . . var. omeiensis.
