989, which illustrates one of the 0. hiennis forms, indicates that one of the 
forms of 0. muricata, L. was intended, having smaller flowers and nar- 
rower leaves than 0. biennis. Toiirnefort’s species (5) therefore clearly 
refers to the present 0. muricata L. 
In (4) the reference R. Par.” is to Hortus Regius Parisiensis, 
1665, which is merely a catalogue of polynomials. ^‘Mor. H. R. Bles.*” 
refers to Morison’s Hortus Regius Blesensis, 1669. Here (p. 126) is 
the earliest recognition I have found of a large-flowered and a small- 
flowered form. In addition to Lysimacliia lutea corniculata of Bauhin’s 
Pinax (which is nearest 0. Lamar ckiana, as I shall show later) are 
listed two forms which were introduced into the London Garden be- 
tween 1655 and 1660. . These are named Lysimacliia corniculata minor 
lutea Canadensis and Lysimacliia lutea flore globoso, Park. Ger. On 
page 284 of the same work Morison says further, ^Hjysimacliia Corni- 
culata, lutea Canadensis minor seu angustifolia: Haec sola foliorum 
angustia, aliarum suarum partium ; horum scilicet & capsularum 
seminalium, parvitate differt, a Lysimacliia Corniculata lutea major! 
Cornuti.” This form with narrower leaves and smaller flowers probably 
belonged to 0. biennis, or possibly to 0. muricata, but in the absence of 
figures I have not been able to trace it further. 
To return to Tournefort, in (3) ‘'Cat. Altdorf. ” refers to Hoffman’s 
Flora Altdorffina, 1677,’ which I have not seen. This plant is undoubtedly 
a large-flowered Oenothera from Virginia, and I am strongly inclined to 
think that it belongs with 0. grandiflora. The reasons for this will be 
given later. 
The reference “H. L. Bat.” in (2) is to Hermann’s Horti Academici 
Jjugduno-B atari Catalogus, 1687, in which are cited Lysimacliia lutea 
corniculata non papposa Virginiana major and Lysimacliia lutea corni- 
culata non papposa Virginiana minor from Morison ’s Plantarum His- 
toriae Universalis Oxoniensis, Part II, p. 271, (1680). In the latter work 
^Morison gives a lengthy description of the former and refers to the large 
yellow flowers. I shall show later that this is close to 0. LamarcMana 
Ser. Avhile the other is undoubtedly a form of 0. biennis L., probably the 
“European biennis,” which has 'flowers someAvhat larger than our Ameri- 
can forms. 
The reference to “C. B. Pin.” in (1) is to Bauhin’s Pinax Tlieatri 
Botanici, firvSt edition 1623. This plant was also certainly nearer 0. 
Jjamarckiana than anything else, as I shall show later. 
It will be well now to trace chronologically some of the early records 
regarding Oenothera. I have not attempted to hunt down every refer- 
ence nor see every plate. But the accuracy of our present knoAvledge
