of Houstonia purpurea, L. 
Roan was a failure botanically, as I found very few new plants. 
I am now fully convinced that the mountain was not to blame, 
but myself, for my sole object seemed to be to get there, and then 
turn around and goback. <Adnus viridis, DC., was very innocent- 
ly passed by under the supposition that it was our common A. 
serrulata. 
The only noteworthy things that I found were Hypericum 
graveolens, Buckley, collected near the hotel among the Adies 
Fraseri, Pursh, Lycopodium Selago, L., and Geum radiatum, Mx., 
along the road on the summit, and Raudbeckia laciniata (L.), var. 
humilis, Gray, on the slope facing the Grassy Knob. 
The region around Salisbury seemed to be doing its best when 
I returned in the latter part of August, but I could do very little, 
as my stay was limited to a few days. However, I collected some 
thirty species, among which were Lotus Helleri, Britton, Fani- 
culum vulgare, Gertn., Elephantopus tomentosus, L.., and Pluchea 
camphorata (L.), DC., (P. purpurascens, DC.) 
My summer’s work and experience, of which this necessarily 
much-condensed article is an account, was very pleasant, and I 
hope to repeat it during the coming summer with much greater 
results.
