Oenoihera alhicaulis Pursh PI., 733 (1814), not O. albicaulis 

 Nutt. Gen. (1818) 

 Oenothera pinnatifida Nutt. Gen. I., 245. (1818) 



As O. alhicaulis Nutt. in Fraser's catalogue is but a nomen 

 nudum, it has no standing. Hence 0. albicaulis Pursh is 

 the first published species bearing that name, which should 

 be restored, though apt to cause some confusion. 

 Oenothera pallida Lindl. Bot Reg. 14 t. 1142. (1830) 



Oenothera albicaulis Nutt. Gen. I., 245 (1818), which name 

 is preoccupied by the foregoing. 

 Epilobium angustifolium L. Spec. PI. 347 (1753) not Lam. 

 Epilobium spicatum Jjam. El. Franc. 1077. (1778) 



This is corrected in Gray's manual, but not in Coulter's. Dr. 

 Trelease in his revision of Epilobium changes it back to 

 E. spicatum, as he believes, as did Lamarck, that E. an- 

 gustifolium L. is the same as E. dodonei Till. ' It would 

 have been strange if Linne had regarded this as the typi- 

 cal E. angustifolium, as the species is comparatively rare 

 in Europe and not found at all in the native land of Linne. 

 What is most common in Sweden is a narrower leaved 

 form of E. angustifolium Jj. , E. spicatum Lam. This is 

 Linne's E. angustifolium a. It grades into the broader 

 leaved form which is common here, Linne's E. angusti- 

 folium h, E. angustifolium latum DC. in Prodr. Linne's 

 E. angustifolium c is E. dodonei Vill. and E. angustifo- 

 lium Lam. 

 Mentzelia decapetala (Pursh). 

 Bartonia decapetala Pursh in Sims Bot. Mag. t 1487 (between 



1810 and 1813) 

 Bartonia ornata Pursh El. 327. (1814) 

 Mentzelia ornata T. & Gr. El. 

 Cactus viviparus Nutt. Gen. I, 295. (1818) 



Mamillaria vivipara Haw. Syn. PI. Succ. Supp. 72. 



Cactus mamillaris, the type of jihe gQnws Mamillaria, Haw., 

 is the first of the two species in Linne's Species Plantarum
