Shnll: Three New Mutations 



355 



THE FUNIFOLIA MUTANT OF OENOTHERA LAMARCKIANA 



The most striking characteristic of this mutation is the curled leaf margin, which gives the 

 appearance of braided rope, whence the name funifolia. It differs also from its parent, Oe. La- 

 marckiana, in having no basal branches. This is one of three new mutants which are likely to be 

 of much use in breeding experiments, and which are described at length in the text. Photograph

lively narrower and, particularly in the 

 stem-leaves, usually narrowing rather 

 abruptly to short-acuminate apexes 

 which are sometimes almost spinescent. 

 Occasionally the midribs of some of the 

 stem-leaves end in a short sub-apical 

 spine-like spur on the under (dorsal) 

 side of the leaf, a characteristic which is 

 much more strikingly and consistently 



associated with revolute leaves in 

 Oenothera pratincola mut. formosa Bart- 

 lett. When typically developed the 

 funifolia plants can be detected readily 

 in very early rosette stages (Fig. 14 

 left) but in less fully developed plants of 

 this type the revolute character does 

 not appear conspicuously in the earlier 

 leaves of the rosette, and the revolute
