Another plant, very closely related to J. officinalis, was collected 

 Sept. 7, 1903, by Dr. (). W. Knight on a railroad embankment at 

 Bangor, Maine, and in Rhodora, vi. 91 (1904) he mentions this 

 collection. Two years later Dr. Knight (I. c. viii. 72) wrote that the 

 plant, "though not spreading seems to hold forth where first found by 

 us." Xo later report seems to have been published, but if one may 

 judge from .1. officinalis L., there is little doubt about the plant 

 becoming established. Therefore 1 it seems advisable to call atten- 

 tion to the relationship of the two introductions. The Maine speci- 

 men was reported (1. c.) as A. arvalis Reichenb. This species has 

 often either been reduced to J. officinalis, or ignored by makers of 

 European manuals. However, Schinz & Thellung in Xaturf. Ges. 

 Zurich, liii. Heft. iv. 557 (1909), have treated Reichenbach's plant 

 as a variety of A. officinalis, identifying it with .1. angustifolia of 

 Linnaeus. According to this disposition its name is .1. officinalis L. 

 var. angustifolia (L. ) A. DC. Rouy, in Rouy & Foucaud's Flore de 

 France, x. 2SS (1908), also regarded A. arvalis as only a variety of -1. 

 officinalis, but he used Reichenbach's name varietally and referred 

 .1. angustifolia L. to another species. Schinz & Thellung, however, 

 on the testimony of Hob. X. Rudmose Brown, who is monographing 

 the genus, show that the identity of A. angustifolia E. Sp. PI. 133 

 (1753) is with Reichenbach's species. 



It seems to me that this disposition is justifiable. At least our 

 European material shows that many intergrades occur between the 

 two forms. The variety, typically, has a looser inflorescence, even 

 the later flowers becoming remote in fruit, the leaves are more or less 

 distinctly denticulate, and the calyx-divisions are less connivent over 

 the fruit. The correct name, then, for the plant introduced at Bangor, 

 Maine, is Anchusa officinalis E., var. angustifolia (E.) A. DC.
