6 BREEDING 



where they had invaded it ; and at this spot they 

 formed a dense thicket of vigorous plants as high as 

 a man. From this point outwards the plants became 

 sparser, and the extreme edge of the area which they 

 covered was occupied by an advance guard of seed- 

 lings and young rosettes. 



Two new species were found in the field — (Enothera 

 IcBvifolia, characterised by its smooth, as opposed 

 to crumpled, leaves and by its narrow petals, which 

 do not overlap one another as do those of 0. Lamarck- 

 iana ; and 0. hrevistylis, characterised by the short- 

 ness of its style, which is so short that, when the 

 flower is first looked into, it looks as if there were no 

 style or stigma. 



Seed was collected from the plants in the potato, 

 field at Hilversum and sown in the Botanic Garden 

 at Amsterdam ; and rosettes — i.e. plants in their 

 first year, which have not yet developed a stem — 

 were also transplanted there. In this way there 

 arose a series of pedigree cultures in which a number 

 of other new species originated. Of these I will 

 only refer to those which are figured in this book. 



(Enothera gig as is the rarest and the finest of the 

 new species which has arisen in the Garden at 

 Amsterdam. It has only appeared three times ; and 

 it is in every respect more vigorous and more heavily 

 built than its parent 0. Lamarchiana. 



The flowering spike is shown in Fig. 2 ; and its 

 fruits, alongside those of 0. Lamarckiaiia, in Fig. 3. 

 The following characteristics of 0. gigas can be made 

 out from these figures. Its leaves are broader ; its
