BERBERIDACEAE. — BERBERIS 377 



Western Szech'uan: south-east of Tachien-lu, thickets, alt. 

 2600-2800 m., June and October 1908 (Nos. 1261, type, 1300); 

 Tachien-lu, uplands, alt. 2800-3400 m., October 1910 (No. 4173; 

 bush 1.5-2 m. high, fruit salmon-red); Mupin, thickets, alt. 2000 m., 

 October 1908 (No. 1050''); without locality, 1904 (Veitch Exped. No. 

 3152=^). 



To this species also belongs Wilson's No. 1320 ex Hort. Veitch. In his B. 

 polyantha, Hemsley has mixed two different species. The true B. pohjantha is repre- 

 sented by Pratt's Nos. 20G and 704, but Pratt's No. 80 is quite different and belongs 

 to this new species. Berberis polyayitha has much thicker leaves with a very fine 

 and narrow reticulation; the inflorescences are broader and looser, the bracts 

 shorter and the elliptical dried fruits are swollen and bear a rather long stjde. 



Berberis Prattii seems also nearly related to B. brevipaniculata Schneider in 

 Bull. Herb. Boissier, ser. 2, VIII. 263 (1908), which was collected by Henry, 

 Ichang, May 1888 (No. 4675). But the last named species differs in its glabrous 

 branches and inflorescences, its smaller leaves, which are distinctly glaucous and 

 papillose beneath and in its shorter panicles and bracts. 



Berberis Prattii, var. recurvata Schneider, n. var. 



A typo recedit inflorescentiis spiciformibus pedicellis fructiferis 

 distincte reflexis. 



Western Szech'uan: Mupin, thickets, alt. 2000-2500 m., June 

 and October 1908 (No. 1073). 



I cannot find any other difference between this variety and the tj'pe, but the 

 narrow inflorescences of the fruiting specimen with the curved pedicels are re- 

 markable. The shape of the rather small leaves is the same as it is in those of 

 No. 1261 {B. Prattii typica).
