grows on ledges of rocks high above valleys, where 2. abortiuus, 
type, or R. abortivus micranthus were never seen. There is fully 
two weeks difference in the time of flowering. The petals exceed — 
the calyx considerably. The plant is more slender, the — 
branches more spreading and graceful, and the head of achenes 
smaller. It may be possible that specimens bearing both these — 
names are in the collection left by the writer at the Ark. Ind — 
Univ. We hardly think this possible and presume the name &. 
abortivus, var. grandiflorus, was found in the MSS. of Dr. 
Engelmann and incorporated in the above list. The var. grand- 
florus should be dropped. F. L. HARVEY.
