ADDITIONS, CORRECTIONS, ETC. 
with me in considering some specimens of Senecio gathered about 
Oxford to be natural hybrids of squalidus and vulgaris. They 
were found on waste ground near Folly Bridge and near the 
Tennis Courts. 
Page 159. Senecio crassifolius, W. At Florence I went over this rather 
et] 
puzzling genus with Mr. Groves. He was quite convinced that 
our plant is identical with Continental crassifolius. Gussone in 
Flore Sicule says that Moretti does not separate crasstfolius from 
leucanthemifolius, and Boissier under the latter name includes 
crassifolius, to which there is no doubt it is closely allied, the 
linear spathulate leaves being the chief point of difference. 
160. S$. vernalis, W. and K. should have an asterisk prefied, and 
casual would perhaps better describe its occurrence here. The 
specimens agreed with a plant so named by Dr. Boswell, but I 
have not seen authentic Continental specimens. Our plants 
appear to be closely allied to leucanthemifolius, but have a more 
erect habit. Boissier in Flor. Orient. asserts that vernalis has 
been frequently distributed under the name of vernus and crassi- 
Solius. 
Our Oxford Senecios are :— 
S. crassifolius, WV. ! 
S$. squalidus, L./ 
Var. a. incisus, Guss. ! 
Var. b. chrysanthemifolius, Guss. ! 
2? Var. c. microglossus. ? parviflorus, Dyer. 
Var. hybrida=vulgaris x squalidus. ! 
8. vernalis, W. and N. ? 
And probably 8. leucanthemifolius, Poir. 
I cannot help believing that all these with vernus, Biv., in- 
crassatus, Guss., apulus, Ten., and humilis, Def., are hybrids of 
vulgaris and squalidus. It is not a little singular that when 
growing on walls in the absence of vulgaris, squalidus is fairly 
constant, but on waste ground where both species occur, there is 
extreme latitude in variation.
