A. R. 



Clematis nutans, var. thyrsoidea (p. 324). This variety has been raised to 

 specific rank and Wilson's No. 1422 separated as a distinct species: 



Clematis Rehderiana Craib in Kew Bull. Misc. Inform. 1914, 150. 



Here belong all the synonyms cited under C. nutans, var. thyrsoidea and the num- 

 bers quoted except Wilson's seed number 1422. 



Clematis Veitchxana Craib, 1. c. 151. 



Here belongs Wilson's seed number 1422, represented at Kew and at the Arnold 

 Arboretum by plants received from Veitch and raised from that seed. 



Clematis Pavoliniana (p. 328). Add the following numbers: 



Western Hupeh: Ichang, alt. 300-1500 m., ravines, 1907 (No. 402; cUmber, 



flowers white, fruit tails yellowish; seeds only); Changyang Hsien, thickets, 1907 



(No. 668; flowers small, white, fruit tails brown). 



Akebia lobata, var. australis (p. 348). Add the following numbers: 

 Western Szech'uan: without precise locaUty, alt. 2000 m., 1908 (Nos. 826, 

 4181 ; large climber, fruits 10 cm. long, purphsh, edible; seeds only). 



Berberis 



Berberis dictyophylla, var. epruinosa (p. 353). Add as a synonym B. Ambro- 

 zyana Schneider, 1. c, p. 356, which was based on a rather poor specimen represent- 

 ing only an insignificant form of the Szech'uan variety of B. dictyophylla Franchet. 

 To the enumeration of specimens under var. epruinosa should be added Wilson's 

 No. 4170 which had been referred to B. diaphana Maximowicz. 



Here it may be also stated that B. approximata Sprague seems to represent a 

 good species the type of which was raised from seeds collected by Farges in eastern 

 Szech'uan and sent to Mr. M. L. de Vilmorin. It is the same as B. dictyophylla 

 Vilmorin & Bois, Frutic. Vilmorin. 1904, 19, fig. (non Franchet) (1905), exclud. 

 descript. lat. Franchetii. 



Berberis diaphana (p. 353). After a careful examination of the dried and living 

 specimens of this Arboretum I beheve that Wilson's No. 930 referred to this species 

 represents the type of the following new species: 



Berberis aemulans Schneider, n. sp.

 mowicz) (1913), quoad specim. Wilsonii No. 930.
