FLORA OF MADAGASCAR. 193 
in à dense terminal pauicle, with long ascending peduncles fur- 
nished with numerous minute erecto-patent linear bracts. In- 
voluere campanulate, 4 in. long and broad; bracts 15-20, lan- 
ceolate, brownish, glabrous. Ligules yellow, shorter than the 
involucre. Disk-flowers numerous, longer than the involucre. 
Pappus pure white, } in. long, much shorter than the disk- 
flowers.— Central Madagascar, Baron! Habit and leaves of S. lon- 
giscapus, Bojer, but capitula very different. This latter has been 
refound by Baron (1684); but I am not at all certain that it is not 
simply a discoid variety of S. cochlearifolius, Bojer (Baron 1534).
