Lvs. triangular, lobed but not divided 3. C. rubescens 



1. Cacalia aconitifolia Bunge M&WMW& (Wu T'ou Yeh Huang Hua Chih; Dark- 

 leaved Senecio scandens) (DC.P. 6: 329). Erect herb, to 1.3 m.; fls. white, pink, 

 purplish, VI-VIII. Northeastern Asia; locally in An., Che., Hun., Hup., Ku. 

 Grassland, shrubland. 



2. Cacalia kraemeri (Fr. & Sav.) Matsum. (Senecio kraemeri Franch. & Savat.) (Fra. 

 & Sav. 2: 406). Erect herb, to 1.2 m.; fls. VI. Northeastern Asia; locally in An. 



Maximowicz (Max. F.165,t.8) has described the genus Syneihsis, with Cacalia aconitifolia as 

 the type species, and separated from Cacalia chiefly by its single convolute cotyledon. Kitamura 

 (Kit.C.3:170) has retained Syneilesis and states, following his study of four species, that 'The 

 cotyledons are always single and folded longitudinally. The base of the petioles of the inferior 

 cauline leaves always completely enclose the stem. These characters are not observed in the 

 typical cacalia " . 



3. Cacalia rubescens (S. Moore) Bailey (Senecio rubescens S. Moore) (B.G. 1: 47). 

 Erect herb, to 1.5m.; fls. white, purplish, VH-IX. Eastern Asia; locally in An., 

 Ki. Brushland. woodland. 



Kitamura (JJ.B.20:196) has named C. matsudae as a species related to C. rubescens, but 

 having all parts larger, and with more numerous flowers in each head. The specimens cited 

 are from western Chekiang.
