APPENDIX. 
20. Tkiodanxs rupestris 906, this is very 
near to the Campanula flagellaris of K until, 
perhaps of this Genus. His Mexican C. perfo- 
liata appears somewhat different from ours by 
dowers geminate and ternate ; yet Torrey would 
have all these to be varieties ! which is the type 
then and the primordial form ? 
21. Helenium discovatum 942, compare it 
with II. mexicanum of Kunth, too shortly noti~ 
ced by him.
