524 WILSON EXPEDITION TO CHINA 
R. villosum Hemsley & Wilson. It is also closely related to R. Augustinii Hemsley, 
which has narrower leaves with midribs densely villose below, unbearded petioles, 
smaller, more numerous, very sparingly lepidote flowers and villose shoots and 
leaves. This new species is rather local in its distribution; its handsome rich 
purple-red flowers make it one of the most beautiful plants in this section. — . 
This species is named for Mary Shreve Ames of North Easton, Massachusetts, 
a generous friend of the Arnold Arboretum and of its Chinese explorations.

Western Hupeh: north and south of Ichang, margins of woods, 
thickets and cliffs, alt. 1300-2300 m., May and November 1907 
(No. 608; shrub 1.5-6 m. tall, flowers rose-pink to deep lavender- 
purple); Fang Hsien, woodlands, alt. 1600-2000 m., May 1907 (No. 
3457; shrub 1-2 m. tall, flowers lilac-purple); Changyang Hsien, 
mountains, alt. 2300 m., May 1900 (Veitch Exped. No. 302). 
Western Szech'uan: Chiu-ting-shan, near Mao-chou, alt. 2000 m., 
May and October 1908 (No. 1207; shrub 1-3 m. tall, flowers light 
rosy-purple); west and near Wén-ch'uan Hsien, alt. 2000-3000 m., 
October and November 1908 (Nos. 1197, 1237; shrub 2-5 m. tall); 
west and near Wén-ch'uan Hsien, woodlands, alt. 2000-2600 m., 
October 1910 (No. 4238; shrub 2-2.5 m. tall). 
This is an exceedingly common species in Hupeh, delighting in rocky situations 
fully exposed to the sun. The flowers vary very much in color, but the species is 
always easily recognizable. No. 3457 from Fang Hsien is more glabrous than 
type, the Szech'uan specimens have slightly longer (1.5-2.5 cm.) and often sparsely 
pilose capsules. The fascicles are usually terminal and 3-flowered; in vigorousshoots, 
however, often six flowers occur in the fascicle and lateral fascicles also develop.
