Whether this plant be really different from Arnica 
Bellidiastrum seems not quite certain; both, however, 
‘are recorded as distinct in the Hortus Kewensis, as well 
as by Wittpenow and Prrsoon. The specimens of each, 
which we have examined, are extremely similar, yet in 
the Arnica we find so long a pappus crowning. the 
germen as to appear quite evident amidst the florets ; 
whereas, in our present plant, the germen is covered with 
short bristles, which project but little beyond the seed, and 
do not form a true pappus. There can be very little doubt 
but that Bexais sylvestris is Properly united to the genus 
Betus, whether it be really distinct from the Bellidiastrum 
of Micuexi or not; but we cannot agree with M. Poirét 
(Encycl. Bot. Suppl. 4. p. 298,) in considering it as a mere 
Variety of Bexurs perennis, from which it differs not only in 
size, but in the proportion of the radius and cals the 
rmer
