sinus alternatim, & in spicam disponuntur : marcescentibus vero illis crassescunt 
siliquae quadratae, duas uncias longae, durae, & perfectae, in quatuor partes 
dehiscentes: copiosa intus, parva, angulosa, fusca, insipida semina continentes, 
& facile, vento agitata planta, decidentia, ut necesse sit cum incipiunt dehiscere, 
eolligere. Auguste floret, & Septembri perflcitur. Folia sapore insipido, quae 
prima facie Keiri sive luteae Violae similia videntur, sinibus levibus excavata, 
quae in caule vix sinuosa apparent, ut facile salignis aequiparari potuerint. 
Flores fructui insident longo tubulo, foliate capite, qui esti quatuor foliolis con- 
structi sint, non tamen ideo cum Keiri aliquid commune habent, siliqua non 
bivalvi, non capitata, nec semina compresso: nec etiam cum vera Lysimachia 
folijs inordinatis, non ternis, nec adstringentibus : fructu diverse cum siliquosa 
dicta sive Chamaenerio non parum, nisi semina huic non papposa essent. Planta 
est levifolia, radice longa parum, & fibrosa, lignosa, quae regerminare solet. 
Iconem expressam addimus. Aliam ejusdem nominis plantam bulbosa radice, 
infra reperies alterius generis fob 257. 
The accompanying figure is that of an Oenothera with large flowers 
and the stigma projecting beyond the stamens. The branching of this 
plant is somewhat unusual, if correctly represented. There are no basal 
branches, but a few long branches near the top. However, I have seen 
plants in cultures with this type of branching, and there is so much 
difference in branching, under different conditions of growth, that this 
point is of little significance. The point of greatest interest in this 
description is the statement regarding the leaves, H sinibus levibus 
excavata. ’ ’ This clearly describes the characteristic crinkling of the 
leaves of 0. Lamar ckiana , and leaves little, if any, doubt that this plant 
was 0. Lamar clxiana in the strict sense. The upper leaves on the stem 
were evidently smooth, as is usually the case in our 0. Lamar chiana. 
The comparison with Salix leaves may indicate that they were somewhat 
narrower than typical 0. Lamar ckiana. 
Regarding the origin of these seeds, which were obtained from John 
Pona in Verona, it is not clear whether the latter had obtained the 
seeds direct from Virginia or had grown several generations of the 
plants before sending seeds to Hernandez. This leaves open the possi- 
bility that crosses might have taken place in the meantime, l)ut if they 
did, the same crosses might haA^e taken place in Virginia among the 
wild plants, so that this contingency does not seem to the writer to ])e 
of importance. 
The reference to fob 257 is to a figure and description of another 
plant in Rerum Med. Nov. Ilisp., published by the same author in the same 
yeai'. This is eAudently a Mexican species of Oenothera. The flowers 
are described as Amrying from red to yellow. 
To return to the description of Ray’s species, number 11, I have con- 
cluded probably belongs to 0 grandipora. Coming from Virginia, it
