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.

p. 9: In 1900 he [E. H. Wilson] collected R. helenae, which was not introduced until 1907.

p. 12-13: From late 1906 to 1909, financed by Harvard’s Arnold Arboretum, Wilson again scoured China for plants. Roses he had seen and collected in 1900 and 1901, such as R. gentiliana, R. helenae, R. giraldii var. venulosa, and R. sertata, he introduced in 1907 or shortly thereafter. ...
Rosa helenae was named for E. H. Wilson’s wife, who died with him in a car accident in 1930. This is another white, scented species rose exhibiting large clusters on very prickly stems. Found from Shensi province, south through eastern Sichuan and western Hupeh, its tangled proliferation grows along wayside thickets and stream-side masses, and rambles vigorously over small trees at the edges of woods. When he first saw this musk rose, Wilson wrote that it “filled the air with its soft fragrance.” The seeds collected in 1907 flowered at the Arnold Arboretum in 1913, proving the species “perfectly hardy.” R. helenae is closely related to the Himalayan R. brunonii

In China he [E. H. Wilson] came across R. hugonis on a narrow arm of the Min Valley, a rose recently sent to England in 1899 by Father Hugo Scallon, the only non-fading yellow rose Wilson saw there. (It produces black hips that drop early.)

In July of 1903 at the extreme western part of Sichuan, Wilson came across the intensely dark red R. moyesii. A common species in mountain thickets, the plant’s flowers vary in color. Vilmorin had described it in 1894, calling it R. macrophylla var. rubrostaminen—rubro referring to red, and dark red is the way most knowledgeable people think of the blossom.

Wilson also chanced across a “pink to rose” form, R. moyesii var. rosea, “very distinct from the type,” also known as R. moyesii fargesii. The leaves are also larger than those of the red. In fact, when grown from seed, the flowers most often are pink. A shrub six to ten feet in height, it grows abundantly in thickets and on the edges of woods. It was named for Reverend J. Moyes, a missionary in Western China.

Rosa multibracteata, an “odd-looking species,” according to Wilson’s observations, seemed limited to the upper stretches of the Min Valley and the Tung Valley near the China-Tibet border. Telltale of this “pretty pink” rose are the many crowded bracts (those small, pale green modified leaflets beneath the flowers) and the numerous, small leaflets on twiggy stems. Harkness described these dainty roses as “small stars of pink with yellow stamens.” They appear both solitary and in terminal clusters. Their hips are orange-red. A late bloomer, the plant grows into a pleasingly rounded shrub about six feet high and about twice as wide.

R. multiflora var. cathayensis, “always pink,” grew commonly everywhere beside streams. The canes are often prostrate, though sometimes erect. The leaves and leaflets vary considerably in size and shape. Wilson believed it to be a parent of the double carnea form, which Thomas Evans had sent from China to England in 1804

In 1908 in western Sichuan and Hupeh, he [E. H. Wilson] saw several garden varieties of R. multiflora var. carnea f. platyphylla, a long name for the double, cultivated rose known in the West as ‘Seven Sisters’.

Another distinct species he [E. H. Wilson] observed in July 1903 and both July and October 1904 on this second Veitch expedition is R. murielae. Although the rose is usually pink, those found along the borders of China and Tibet generate white flowers and grey-green leaves. Closely related to R. davidii ...., it is a much branched plant bearing clusters in corymbs. Wilson observed R. murielae also in 1908 and 1910 during his treks for the Arnold Arboretum. He named it for his daughter.
