[Beie unable to find room for Mr. Buckley’s detailed account 
2 a botanical tour through the mountains of Alabama, Georgia, 
Tennessee, and Carolina, we have, in accordance with his re- 
quest, merely extracted the description of new species for present 
publication. We also append, in a note, the diagnostic character 
of a new genus of Santalacez, established by Dr. Torrey, upon 
materials chiefly furnished by Mr. Buckley, to whom it is dedi- 
eated ; a full account and figure of which will hereafter be ane 
in this Journal.*—Ebs. | 
_ Srrepropus macu.atus (n. sp.): stem and nerves of the lower

of the branches, not distorted ; sepals subspatulate, acuminate, 
yellowish-white with numerous purple spots, rather longer than 
the filaments; anthers oblong ; uss longer than the stamens ;
