146 -Rhodora [AUGUST 
actaeifolium, was Angelica lucida ; and in the 2d edition of the Manual, 
we find at the end of the account of Archangelica peregrina the note: 
“Perhaps it is the Angelica lucida L."' In the 3d edition this note 
was dropped and in its stead appeared: “It is A[rchangelica] Gmelini, 
of N. W. America," * and in the 5th edition (1867) the plant was 
formally taken up as Archangelica Gmelini DC., while in Watson & 
Coulter's revision (ed. 6) it became Coelopleurum Gmelini Ledeb. 
That in 1856 Dr. Gray was correct in his surmise that the Coelo- 
pleurum of northeastern America is Angelica lucida L. cannot be 
doubted for a moment by any one who has become familiar with the 
plant in the field. Although in rich woods or in fertile seashore- 
thickets the plant may exceed 1 m. in height, thus greatly exceeding 
the prescription, * Angelicae lucidae vix cubitum implet caulis" of 
Cornut, in dry thickets and on rocky or gravelly, bushy slopes (the 
" [nter siluarum aprica” of Cornut) the mature plant is only 2.54 dm. 
high and the Cornut plate is beautifully matched by such sheets as 
. Sornborger, no. 50, from Hopedale, Labrador, Fernald & Wiegand, 
no. 3,776, from Blane Sablon, Labrador, Fernald & Wiegand, no. 3,775, 
from Ingornachoix Bay, Newfoundland, Bro. Victorin, no. 76, from 
Notre-Dame de Portage, Quebec; all distributed either as Coelo- 
pleurum Gmelini or C. actaeifolium. There is, then, no question that 
Cornut’s Angelica lucida, published in 1635 from Canada, actually 
was of Canadian origin and that he illustrated a beautifully charac- 
teristic small specimen of the species which has recently passed as 
Coelopleurum actaeifolium (Michx.) Coult. & Rose. It is gratifying 
to clear the obscurity which has so long invested this species and to 
reinstate a plant taken up by Linnaeus in the Species Plantarum.
