374 WILSON EXPEDITION TO CHINA 
locality, August 1876, S. W. Williams; Peking, Temple of Heaven, September, 
15, 1903, C. S. Sargent; same locality, October 3, 1905, J. G. Jack; Peking, city 
wall, July 5, 1915, F. N. Meyer (No. 1008); Peking-Kolgan road, hills near Great 
Wall, October 5, 1905, J. G. Jack. Shantung: Chifu, September 22, 1903, C. S. 
Sargent; Tsingtau, 1901, R. Zimmermann (No. 442). 
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 
Chili 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 à 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 like Wilson's No. 4308*, and this form 
has been distinguished by Franchet as V. incisa, var. heterophylla (in Nouv. Arch. 
Mus. Paris, sér. 2, VI. 112 (Pl. 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 (Ill. Handb. Laubholzk. II. 594 [1911]. — Agnus castus incisa, var. 
multifida Carriére 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- 
ern China which represent the typical V. quinata have a smaller inflorescence 
smaller leaflets narrower at the base. Henry’s specimens from Yunnan have longer 
and narrower glabrous or nearly glabrous leaflets.
