Aracallus CAMPESTRis (DC.) var. JoHANNENSis, Fernald, Rhodora, 

 vol. I, p. 88. 



The Canadian stations given for this plant by Mr. Fernald 

 are Isle d'Orleans below Quebec. (Mrs. Shepatd, Prof. Brunei. ) 

 Mouth of Madawaska River, N.B. ( G. U. Hay, G. F. Matthew.) 

 Crevices of ledges, Aroostook Falls, N.B. (M. L. FemaLd. ) 

 Rocky banks, Hero's Rapids, Restigouche River, N.B. ( G. U. 

 Hay. ) Our only herbarium specimens were collected at Aroostook 

 Falls, N.B., by Mr. G. U. Hay, in 1883 and at Woodstock N.B. 

 by Prof. Macoun in 1890. 



Aragallus caudatus, Greene, Pittonia, vol, iv, p. 69. 



Moose Jaw, Assa., June 26th, 1896, Herb. No. 13,957-* 

 {^John Macotin.) A very beautiful and distinct species, not at all 

 resembling the common A. Richardsonii oi the prairies. 



Aragallus foliolosus, Hook. Fl. Bor. Am., vol. i., p. 146. 

 O. foljosa, T. & G. Fl., p. 339. 



In describing O. folio losa. Hooker says : " Capitula late ovata 

 seu subglobosa, ratione plant ce parva, floribus compactis, patentibus, 

 inferioribus reflexis." How an acaulescent plant with compact 

 heads — heads "far more compact" than O. ccerulea — should ever 

 have been referred to O. defiexa will probably never be fully ex- 

 plained ; that it has no very close affinity with that species is 

 evident. The error doubtless originated in cowiwsxn^ O. foliolosa 

 with an apparently acaulescent form of O. deflexa, (Proc. Am. Ac. 

 Arts & Sc, vol. XX, p. 4) the '■'■forma subacaulis" to which Gray 

 referred O. foliolosa. It is indeed probable that in describing O. 

 foliolosa, Hooker had before him the flowers of that species and 

 fruiting specimens of the sub-acaulescent form of O. defiexa which 

 is not uncommon in the region traversed by Richardson and 

 Drummond. Our specimens agree in every particular with his 

 description of O. foliolosa until the fruit is reached, the " rather 

 remote, deflexed " legumes, "an inch long" are those of O. 

 defiexa, while "compact broadly ovate heads" could not refer to
