treating of the botany of these mountains, igapnica to this 
rnal in January, 1842, I ventured to found a genus upon this 
plant, under the above name, trusting that the ailigent search 
prosecuted by myself and by all botanists visiting the ion 
would duly bring it to light. The protracted failure of

Peck, bearing a recent date on the title page, although unrevised since 1857.
