BERBERIDACEAB. — BERBERIS 375 



This interesting plant, of which I have only seen a small branch with immature 

 fruits, is readily distinguished by the reticulation and dentation of its leaves. 

 It seems most nearly allied to B. dubia Schneider in Bull. Herb. Boissier, scr. 2, 

 V. 663 (1900); VIII. 259 (1908) from western Mongolia and Kansu, which differs 

 chiefly in the somewhat different reticulation and dentation of the smaller leaves 

 and in the shorter pedicels.

 bourg, XXIII. 308 (1877); Fl. Tangut. 30. t. 7, fig. 8-13 (1889).— 

 Sclmeider in Bull. Herb. Boissier, ser. 2, V. 664 (1905); VIII. 262 

 (1908). 



Western Hupeh : Hsing-shan Hsien, woodlands, alt. 1300- 

 1600 m., June and November 1907 (No. 554; bush 1.30-2 m. high, 

 flowers yellow, fruit scarlet); upland thickets. Fang Hsien, alt. 

 3200-3600 m. (No. 4416; bush 1.25-2 m. tall, fruit scarlet); without 

 locality, June 1901 (Veitch Exped. No. 1915). 



The inflorescence is sometimes somewhat paniculate near the base. The fruits 

 are elliptic, up to 11 mm. long and 6 mm. across with a sessile stigma. 

 Here may be added the two following species collected by Mr. Purdom. 



Berberis amurensis Ruprecht, in Bull. Acad. Sci. St. Petersbourg, XV. 216 (1857). 

 Northern Chili: Weichang, 1909, W. Purdom (No. 34). 



Berberis Gilgiana Fedde in Bot. Jahrb. XXXVI. Beibl. LXXXII. 43 (1905). — 

 Schneider in Bull. Herb. Boissier, s6t. 2, VIII. 262 (1908). 



Shensi: Tai-pei-shan, 1910, W. Purdom (Nos. 6, 8). 



Purdom's specimens have the leaves somewhat broader and shorter and more 

 rhombic-ovate, but I cannot find any other great difference in them. 



Sect. POLYANTHAE Schneider. 



Berberis aggregata Schneider in Bull. Herb. Boissier, ser. 2, VIII. 

 203 (1908); HI. Handb. Laubholzk. II. 918 (1912). 



Western Szech'uan: Pan-lan-shan, west of Kuan Hsien, side of 

 streams, alt. 2600 m., June 21, 1908 (No. 2870; bush 1-1.20 cm. high, 

 flowers yellow); Min valley, thickets, alt. 1300-2300 m., October 

 1908 (No. 1050; bush 0.60-1.20 m. high, fruit salmon-red); Mupin, 

 thickets, alt. 2600-3000 m., October 1910 (No. 4286; bush 1.60 m. 

 high, fruit bright red). 



The type was collected by Potanin in eastern Kansu "valle fl. Hei ho" and 

 most of its inflorescences are distinctly compound, so it seems to be better to place 

 this species in the Section Polyanthae.
