Li/siutacltia lutea coniicxlata of Bauhin, 2 which Tourne- 

 fort cites as a synonym for his OiM^ra latifolia, is the 

 same plant, or at any rate the same description, as 

 Morison's Lgsimachia lutea corniculata nan papposa 

 and Ray's Lgsimachia Intra Virginiana, The crucial 

 point in this early synonymy seems to he in Barrelier 

 (1714), who gives rather accurate figures of three 

 species of Oenothera, together with their synonymy (see 

 Gates, '11a, p. 102). His species (1) is quite certainly a 

 race of 0. biennis, his species (2) is with equal certainty 

 a race of 0. muricata, and (.'!). which has much larger 

 flowers, must, I think, belong somewhere in the series of 



0. Lamarckiana. The fact that the name Lgsi maehia 

 lutea, corniculata, latifolia, Lusitauica under which Bar- 

 relier figures his species ('.)) is almost identical with the 

 name Lysimacltia Virginiana latifolia, lutea, cornicu- 

 lata under which Morison figures his large-flowered 

 form (Fig. 7), made it probable that Barrelier's species 

 (3) referred to the same plant as Morison's figure. How- 

 ever, this can not be certain. But I regard it as quite 

 certain that the plant figured by Morison (Fig. 8) under 

 the name Lysimachia Virginiana angustifolia, cornicu- 

 lata (see Gates, '11a, p. 99) is 0. muricata. The diam- 

 eter of the flowers in his Fig. 7 is exactly three times that 

 in Fig. 8. Now Gray's ' ' Manual," ed. 7, gives the 

 length of petals in 0. muricata as 12-20 mm., in 0. bi- 

 ennis as 15-25 mm., and in 0. grandiflora as 40-60 mm., 

 so that the flowers of O. grandiflora (or O. Lamarckiana) 

 would be approximately three times the diameter of 

 those in O. muricata, while even the "European biennis" 

 could scarcely reach these dimensions. This appears to 

 be an additional reason for supposing that Morison's 

 larger-flowered plant came in the series represented by
