rapprochées. Le calice est jaune, muni d’un tube un peu plus 
long que la corolle, qui se divise en quatre folioles lancéolées, 
élargies 4 leur base, aigués a leur sommet, terminées par un 
filet court, sétacé. La corolle est jaune, composée de quatre 
pétales ovales, trés-grands, entiers, arrondis, presque aussi 
longs que le tube calicinal, retrécis 4 leur base en forme de 
coin. Les anthéres sont longues, linéaires. Le fruit est une 
capsule courte, cylindrique, glabre, tronquée, légérement quad- 
rangulaire, n’ayant qu’environ le tiers de longueur du tube 
calicinal. Cette espéce est originaire de 1’Amérique septen- 
trionale. On la cultive au jardin du Muséum d'Histoire 
naturelle. (V.S.)”’ 
An interesting point has been brought to my notice by Mr. 
H. H. Bartlett. Poiret has this note in the Encyclopédie Métho- 
dique Botanique, Suppl. 4: 141. 1816: “T’Oenothera grandiflora, 
no. 11, est la méme plante que celle d’Aiton, Hort. Kew., 2, pas: 
2.” The designation ‘no. 11” instead of ‘no, 12”’ must have 
been a slip of the pen on Poiret’s part. Although Poiret was 
correct in considering O. grandiflora Lamarck as a synonym of 0. 
grandiflora Solander, he could not have had a clear conception of 
this plant since he kept O. suaveolens Desfontaines, which is also a 
synonym, as a distinct species. 
We will give also the short diagnosis by Seringe (1828) of 
Oenothera Lamarckiana for comparison with the longer description 
of Lamarck. 
“OE. Lamarckiana (Ser. mss.) caule ramoso, foliis wnteger- 
rimis ovato-lanceolatis, petalis integris magnis, capsulis glabris 
cylindrico-tetragonis brevibus. @ in America sept. OE 
grandiflora Lam. dict. 4. p. 554. *non Ait. Fl. flavi.” ; 
I have italicized phrases that are the same as those in the brief 
introduction in the description of Lamarck, showing that Seringe 
had little or nothing to add to the original description. 
Certain points should be noted in these descriptions of Lamarck 
and Seringe before we compare Lamarck’s plant (PLATE 37). the 
one hand with O. grandiflora Solander and on the other with the 
material of De Vries’s cultures (““O. Lamarckiana De Vries”). The 
ed, for 
description of the petals as entire must not be emphasiz , 
while there may not be in these species a conspicuous notch at 
tip of the petals there is usually at least a shallow indenta
