Related to R. longicuspis is R. glomerata, which Wilson found growing among underbrush of the Tung River Valley of western Sichuan in 1908 and again in 1910. Its name refers to its round flower heads. The large leaflets show strongly reticulate veins. The densely packed corymbs of fragrant white flowers sit on short peduncles. Like R. helenae and R. filipes, this unrestrained species belongs in the taxonomy section of Synstylae (its styles protruding and fused into a column). After other Synstylae species have spent their bloom, R. glomerata sends out its flowers in late June or even July.

Description in Latin. Enjoy.
This very distinct species readily distinguished by its large leaflets with strong...venation [pattern of veins] and villose pubscence [long hairy downy surface] on the underside, by its large ...stipules, by its short-peduncled dense corymbs...
It is related to Rosa longicuspis which is nearly glabrous [smooth] everywhere and has shining green leaves with much less prominent venation, flowers on longer pedicels, and a very much larger red or scarlet fruit. This new species has a rather local distribution.
