This variety has been by most authors considered a distinct species, but it differs 

 only in its more deeply and incisely serrate or even pinnatifid leaflets; it represents 

 the northern form of the species and seems well separated geographically, ranging 

 from northeastern Szech'uan through Shensi and northwestern Hupeh to northern 

 ChiH and eastern Shantung, while the typical form ranges southward to India and 

 Malaya. The latter has also been recorded from the Philippine Islands, but the 

 specimens I have seen differ considerably in the character of the inflorescence. The 

 var. incisa shows a great range of variation in the shape of the leaflets; some 

 specimens approach the type by their broad only deeply serrate leaflets, as 

 Zimmermann's No. 442 from Tsingtau, others have serrate or sometimes entire and 

 pinnatisect leaflets often on the same branch hke Wilson's No. 4308*^, and this form 

 has been distinguished by Franchet as V. incisa, var. heterophylla (in Nouv. Arch. 

 Mus. Paris, ser. 2, VI. 112 [PI. David. I. 232] [1883]), while the most extreme 

 forms have deeply pinnatifid leaflets with comparatively narrow and often remote 

 segments as in Wilson's No. 4308; this form has been named V. incisa, var. multi- 

 fida Schneider (III. Handb. Laubholzk. II. 594 [1911]. — Agnus castus incisa, var. 

 multifida Carriere in Rev. Hort. 1871, 416).

This species does not seem to have been recorded before from western China, 

 Wilson's No. 408 has very large leaflets, broadly cuneate or nearly rounded at the 

 base, the terminal one attaining 14 cm. in length, and large inflorescences from 

 16 to 24 cm. long; it resembles thus more the Indian plant, but differs from it in the 

 finely pubescent veins of the under side of the leaves, while the specimens from east- 

 em China which represent the typical V. quinata have a smaller inflorescence and 

 smaller leaflets narrower at the base. Henry's specimens from Yunnan have longer 

 and narrower glabrous or nearly glabrous leaflets.
