Berberis yunnanensis, Franch. in Bull. Soc, Bot. France, vol. xxxiii, 1886, 
p. 888; Schneider, Laubholzk. vol. i. 1904, p. 306; affinis B. macrosepalae, 
Hook. f., a@ qua ramulis glabris, petalis acutioribus, glandulis minoribus 
differt. 
Frutex 1-2 m. altus, ramis angulato-striatis cinereis. Folia obovato-cuneata, 
apice rotundata, mucronata, 2-4 em. longa, 0°8-1°5 em. lata, integra vel 
spinuloso-serrata, spinulis 1 mm. longis; venae laxae, utrinque conspicuae ; 
spinae 3- vel 5-partitae, 1-2 cm. longae, patentes. Flores solitarii vel 
fasciculati, circiter 2 cm. diametro, perulis ovatis; pedicelli graciles, 
1°5-2 cm. longi. Sepa/a 6 vel 7, subaequalia, ovata vel elliptica, 6-8 mm. 
longa, 4-5 mm. lata. Petala late obovata, subacuta, leviter emarginata, 
5-6 mm. longa, 3-4 mm. lata, pallide flava, glandulis 2 ellipticis 0°75 mm. 
longis intus basi instructa. Stamina quam petala duplo breviora. Stigma 
Seman capitatum, acca rubra, ellipsoidea, LO-15 mm. longa, 7-8 mm. 
diametro. 
Though very closely allied to Berberis macrosepala, 
Hook. f., B. yunnanensis is nevertheless distinguishable by 
more characters than are indicated by Schneider in the 
places cited above. He states that the only difference he 
could find between the two species was that the young 
branches of B. yunnanensis were glabrous and those of 
B. macrosepala shortly pubescent. In B. yunnanensis, how- 
ever, the petals are acute and scarcely emarginate, and bear 
small rounded glands; whereas in B. macrosepala they are 
obtuse with a broad, widely emarginate apex, and the glands 
are larger and more elongated. 
B. yunnanensis was first discovered by Delavay in 1885 
near Lankong, Yunnan, at an altitude of 10,000 ft. Since 
then it has been collected in Western China by Wilson, who 
also gathered B. maerosepala in the same region; thus 
greatly extending the known range of that species, which 
was known only from the Sikkim Himalaya.
