AX UNDESCEIBED SENECIO FROM SOUTH AFRICA. 
By Dr. F. Mueller, F.R.S. 
i 
In a communication from Peter M'Owan, Esq., Principal of Shaw 
College, Grahamstown, I have been desired to give an opinion on the 
pecific validity of a new species of Senecio, discovered by that learned 
a »d ardent investigator of South African plants in Algoa Bay. I 
entered on my task with all the more pleasure, not only because the 
museum of Melbourne is extremely rich in plants from extratropical 
Africa, for comparison, but because I was anxious to promote in any 
•*y within my power the researches of a gentleman who already ex- 
e ^ises important bearings on the elucidation of the plants of the 
Ca peland, and who, moreover, has commenced to add largely to the 
* "Apparently an undescribed species of the A marella section, where, on ac- 
count of the hair-crown being wanting, it will have to be ranged near G. Moor- 
voftiana, Wall., from which it diners by its smaUer flowers, its acute lobes of 
f*°lla, and its calyx, making it allied to G. Germanic-a." (Professor Grise- 
fach's L ttter to Editor of « Journal of Botany,' dated July 20, 18<;7.)
