Oenothera Gig as.

flowering part of the stem I found the length of the 

 internode between two nearly ripe fruits to be barely 

 . 5 cm. Moreover the leaves are broader, the bracts 

 bigger and, for this reason, the whole fruit-bearing spike 

 less naked.

 difference in breadth. L, Oenothera Lamarckiana; G, 

 Oenothera gigas. 



I recognized the species, when I first saw it in my 

 cultures in 1896, by its short stumpy fruits crowded to- 

 gether and also by its cup-shaped flowers.
