Barrelier’s figure of Lysimachia lutea corniculata latifolia hisitanica 
together with the figure of Morison’s already referred to. It is very 
probable that Barrelier’s plant was the same as Morison’s. The names 
used are almost identical but Barrelier cites as a synonym for his plant 
Tournefort’s Onagra latifolia, floribus amplis. The latter is very prob- 
ably our present 0. grandiflora Ait. Linnaeus in the Hort. Cliff, evi- 
dently concludes that Morison’s and Barrelier’s plants are the same, 
and segregates Onagra latiflora, floribus amplis as a subform. There- 
fore the type of Linnaeus’ 0. biennis was a large-flowered form in the 
0. Lamar chiana series and may perhaps, have also included a form in 
the 0. grandiflora series, if Barrelier was correct in his synononiy. But 
all the figures and names of small-flowered forms were definitely ex- 
cluded, or rather ignored by Linnaeus. 
After Linnaeus’ time the small-flowered forms were included indis- 
criminately with the large-dowered ones under ' 0. biennis L. The 
large-dowered forms later came to be designated 0. biennis var. grand- 
iflora until after the recognition again of 0. grandiflora Ait. and 0. 
Lamarckiana Ser. as separate species. Since then the name 0. biennis 
L. has been chiedy condned to the small-dowered forms, although Lin- 
naeus evidently intended as the type of his species the large-dowered 
forms. We know now that the difference between large and small- 
dowered species in Oenothera is an imx^ortant one, involving various 
other changes in dower parts and connected with the habit of open or 
close pollination. 
Ray described two large-dowered species in 1686. One of these was 
probably 0. Lamarckiana and the other 0. grandiflora, from its Eastern 
range in Carolina and Georgia. This is described as having broader 
leaves and much larger dowers. 
In 1778 0. grandiflora Ait. was introduced into England after its dis- 
covery in Alabama by Bartram. It was described by Aiton, Willdenow, 
and by L’Heritier whose description (the most accurate) was never pub- 
lished, until reproduced here. Poiret described a plant in Lamarck’s 
Dictionnaire in 1796 under the name 0. grandiflora. This was recog- 
nized by Seringe to be different from the 0. grandiflora of Aiton and 
Willdenow, and was named by him 0. Jjamarckiana. In this way Avas 
segregated a form which had long been going under the name 0. biennis 
L. These now well-known facts have Leen brought together 1)y DeVries 
and MacDougal. 
In 1860 0. Lamarckiana Ser. Avas reintroduced into England from 
Texas. Seeds AA^ere distributed on the continent and this DeVries has 
shoAvn to be the probable source of the 0. Lamarckiana noAv groAvn in 
European gardens, and the source of his cultures. It is not impossible
