CORRECTIONS AND ADDITIONS TO VOLUME I 443 



the long (10-12 cm.) inflorescences which are said to be " infra subpaniculatae." 

 Such long inflorescences I know only in B. Feddeana Schneider. Not having before 

 me Fedde's type I cannot decide the question of its identity with any of the species 

 known to me. Purdom's specimens are not quite identical with the typical B. 

 dasystachya, especially the flowers of No. 5 are somewhat larger. The typical 

 form is in cultivation in this Arboretum; the plants came from Vilmorin and the 

 exact region where the seeds were collected is not known. 



Berberis Prattii (p. 376). This species is connected with B. aggregata Schneider 

 by many inlcTmodiate forms according to the hving plants in this Arboretum. I 

 therefore reduce it to the following variety : 



Berberis aggregata, var. Prattu Schneider, n. var. 



B. brevipaniculata Bean., Trees & Shrubs Gr. Brit. I. 236 (non Schneider) (1914). 

 B. Geraldii Veitch, New Hardy PI. China {Cat.), 1913, 7 (nomen nudum). 



Bean's plant is entirely different from B. brevipaniculata Schneider which is a 

 Hupeh plant and not yet in cultivation. The cultivated form was introduced by 

 Wilson in 1904 from near Tachien-lu, and it is growing in this Arboretum under No. 

 1320 from Hort. Veitch. It is one of those intermediate forms, and very similar to 

 the plant figured in Bot. Mag. CXL. t. 8549 (1914). Bean mentions, and it is also 

 mentioned by Sprague in the Botanical Magazine, that the leaves of B. Prattii are 

 pale green beneath and not glaucous, as in those of what he calls B. brevipani- 

 culata. But according to my observations in this Arboretum these differences in 

 the color of the leaves are apparently not constant and arc due to local conditions 

 or the individual behavior of the plants. 



There is also the following variety : 



Berberis aggregata, var. recurvata Schneider, n. comb. 



Berberis Prattii, var. recurvata Schneider (p. 377). 



As the cultivated plants in this Arboretum have not flowered, it is impossible to 

 decide whether this is a good variety or a mere form. 



Berberis (p. 377). After B. Liechtensteinii insert the following numbers: 



Berberis spec. 



Western Szech'uan: southeast of Tachien-lu, alt. 2500 m., 1910 (No. 4130; 

 shrub 1-1.5 m., flowers yellow, fruits black; seeds only). 



Berberis spec. 



Western Szech'uan: west and near Wen-ch'uan Hsien, thickets, alt. 2300- 

 2800 m., 1910 (No. 4153; bush 2-2.5 m. tall, fruits scarlet in cymose racemes). 



Berberis spec. 



Western Szech'uan: Sungpan, alt. 3000 m., 1910 (No. 4203; bush 3-4 m. 

 tall, leaves b oadly obovate, fruits black in cyrnose racemes). 



This and the preceding number are not available at present for determination, 

 as they have been loaned to a European collection. C. S.
