HOSACEAE. — ROSA 329 



This variety is distinguished from the type by its leaflets, which are very markedly 

 reticulate on the under side. In the No. 3533 the leaflets are glabrous or nearly 

 so on the upper surface. This new variety is a bush 1.5-2.5 m. tall, with pink 

 flowers and ovoid, scarlet, subsessile fruit.

Western Szech'uan: Tachien-lu, thickets, alt. 2600-3000 m., 

 June and October 1908, October 1910, Nos. 1254, 1244, 4093; bush 

 1.5-2.5 m. tall, flowers pink, fruit orange-red to scarlet; same locality, 

 October 1903 (Veitch Exped. Seed Nos. 1563, 1727; bush 1 m. tall); 

 same locality, A. E. Pratt (No. 116, type); northeast of Tachien-lu, 

 Ta-p'ao-shan, thickets, alt. 2300-3000 m., July 3, 1908 (No. 3581; 

 bush 2-2.5 m. tall, flowers deep rose-pink); Wa-shan, thickets, alt. 

 2600-3300 m., July and October 1908 (No. 1150; bush 2 m., flowers 

 pink, fruit scarlet). 



This pretty little Rose is common in thickets near Tachien-lu. It may be recog- 

 nized by its umbellate-cymose inflorescence of 3 to several small flowers and by its 

 small leaves of 5-7 pairs of small lanceolate to oval or rarely obovate leaflets. 

 The prickles are straight, aciculate, somewhat dilated at the base, and straw-col- 

 ored; the shoots are reddish, smooth or strongly setose. The No. 1150 has very 

 small leaves, composed of oval to suborbicular leaflets, and may possibly represent 

 a distinct variety.

Western Szech'uan: near Monkong Ting, valley of Hsao-chin 

 Ho, alt. 2300-3060 m., June 1908 (No. 3602; bush 2-2.5 m. tall, flowers 

 rose-pink); neighborhood of Sungpan Ting, side of streams, alt. 

 2600-3150 m., August 28, 1910 (Nos. 4009, 4026^; bush 1.5-3 m. tall, 

 flowers rose-pink, fruit orange-red); west of Tachien-lu, banks of 

 Yalung River, June 1904 (Veitch Exped. No. 35341 bush 1-2.5 m. 

 tall). 



This Rose is fairly common in the more arid river-valleys of western Szech'uan 

 and is very abundant in the neighborhood of the city of Sungpan Ting. The 

 flowers are solitary, or very rarely two together; the fruit is smooth, ovoid, 

 orange-red with a thin pericarp and large achenes; the calyx is deciduous 

 from the ripe fruit. The stems are ascending and spreading and much-branched 

 and glaucescent, and the prickles are reddish when young, occasionally flattened, 

 somewhat decurrent, and straw-colored when mature. Both in flower and fruit 

 this is a very pleasing plant. The closely related R. Wcbhiana Wallich has an 

 elongate, sparsely glandular fruit crowned by a persistent calyx in which the lobes 

 are very long.
