CORRECTIONS. 
For Cerastium boreale, (p. 70, 1. 6,) read Stellaria borealis. 
7, Anemone Hepatica, L. Change ‘‘ Genesee” to ‘‘ Wyoming.” 
15. Ranunculus alismefolius, Geyer. Change specific name and that of its 
author to ‘‘ambigens, Watson.” 
27. Trollius laxus, Salisb. Change ‘‘ Genesee” to ‘‘ Wyoming.” 
68. Cardamine rotundifolia, Michx. Prof. WaTson, in transferring this 
name tothe plant, which TorREY called C. rhomdboidea, DC., var. 
purpurea, seems to have fallen into an error. (See GRAy’s note in the 
Botanical Gazette, Vol. 4, p. 210). Butthat the plant itself is entitled to 
specific rank admits, in our opinion, of little doubt. 
Cardamine hirsuta, L., var. sylvatica. Add ‘‘ Gray ”’ as the authority for 
the variety. 
85. BRASSICA NIGRA, Gray. Substitute ‘‘ Koch” for ‘‘ Gray.” 
g2. THLASPI ARVENSIS, L.. Change ‘‘ ARVENSIS”’ to ‘* ARVENSE.”’ 
For ‘‘ ORDER I1. CAPSARIDACE4”’ read ‘‘ ORDER II. CAPPARIDACE,” 
123. DIANTHUS ARMERIA. Add ‘‘ L”’ to denote the authority.
