324 WILSON EXPEDITION TO CHINA 



Rosa macrophylla, var. crasseaculeata M. de Vilmorin in Jour. Hart. Soc. 

 Land. XXVil, 487, figs. 135, 136 (1902-03). 



Western Hupeh: Fang Hsien, upland thickets, alt. 2000-2600 m., 

 July and September 1907 (No. 272; bush 1-3 m. tall, flowers pink, 

 fruit coral-red;) same locality July and October 1901 (Veitch Exped. 

 Nos. 2409% type, 2409, Seed No. 1047). 



This well-marked species with its shoots thickly clad with short, stout, flattened 

 prickles is local in its distribution, and is known to us only from the northwest 

 comer of Ilupeh and the adjacent region in Szech'uan. The inflorescence varies 

 considerably in size, being largely dependent upon vigor of growth. 



Rosa saturata Baker in Willmott, Gen. Rosa^ II. 503 (1914). 



Western Hupeh: Fang Hsien, thickets, alt. 1600-2300 m., July 

 and September 1907 (No. 316; bush 1-2.5 m. tall, flowers rose-red, 

 fruit coral-red); same locality, June 1901 (Veitch Exped. No. 2086, 

 flowers pink, rare); without locality, A. Henry (No. 6747). North- 

 central Szech'uan : Pa-chou, thickets, alt. 1000 m., July 1910 (No. 

 4646; bush 1-2 m., flowers dark red). 



This species is closely related to Rosa hanksiopsis Baker, which has smaller leaves 

 and smaller usually clustered flowers. It is rather rare and is apparently restricted 

 to northwestern Hupeh and the more northern parts of the Red Basin of Szech'uan.

 Spec, Nov. XI. 531, fig. 3 (1913). 



Western Szech'uan: Ta-p'ao-shan, northeast of Tachien-lu, 

 thickets, alt. 3000-3300 m., July 4, 1908 (No. 3584; bush 2-4 m. tall, 

 flowers deep rose); west of Kuan Hsien, Pan-lan-shan, thickets, alt. 

 2300-3600 m., June 1908 (No. 3588; bush 3-5 m., flowers deep rose); 

 neighborhood of Sungpan Ting, alt. 3000 m., August 27, 1910 (No. 

 4028); same locality, alt. 2500-2600 m., September 1903 (Veitch 

 Exped. Seed No. 1447; bush 1-2 m. tall). Kansu: Min-chou, alt, 

 3000 m., 1911, Tf . Purdom. 



This Rose is closely related to R. setipoda Hemsley & Wilson, and is perhaps 

 nothing but a geographical form of that species distinguished by its more hairy leaves, 

 smaller inflorescence, and by its rounder flowers with shorter calyx-lobes. No. 

 4028, from Sunp^^an, differs from the type in the absence of bristles on the fruit and 

 pedicels and in the unarmed branches, but the plants raised from seed collected in 

 1903 in the same locality have setose pedicels and receptacles and the branches are 

 armed with broad prickles. No. 3584 from the Ta-p'ao-shan differs in the slenderer 

 prickles and the small broader, sometimes nearly orbicular leaflets. In all speci- 

 mens except Purdora's the leaflets are simply or nearly simply serrate, but the young 

 plants raised from seed have doubly serrate leaflets.
