HYBItlD FOXGLOVE. 



The hybrid plants of Digilnlis purpurea L. upon D. lanafa 

 Ehrb. prodnced flower stems from four to six feet bigb, brancbing 

 much and forming an unusual type of border plant. Hundreds of 

 the purple-tinged creamy flowers were open at the same time and 

 constantly visited by insects, but no seeds were produced. The 

 capsules would swell hopefully for some days and then become 

 wrinkled. Many attempts were made to get seed by hand pollina- 

 tion without success, even w^hen it came from the small-flowered 

 parent iX Jaiiaia. 



Thore was some range of size and markings of the flowers among 

 the p'lants, in fact no two were entirely alike. It was also noted 

 that certain of the flowers were nuich larger than the ordinary 

 upon the plant, reminding one of the monstrous blooms that are 

 often met with in the purple foxglove, particularly at the end of 

 the flower stem. But in this case they were among their fellows 

 along the axis of the plant. 



HYBRID NICOTIAlSrA. 



A nmnber of first generation plants of the hybrid ''Nicotiana 

 Sandrid-N . alata" were grown this season. Some had the purt^ 

 white flowers of N. alaich, while others' showed strong coloring 

 upon the outer surface of the corolla. The decided odor of N. 

 alata was not in any of the hybrids, a faint perfume only being de- 

 tected. No plant had flowers as small as those of N. "Sandrea," 

 nor was its rich color inherited, but instead unattraotive, subdued 

 derivatives prevailed. One plant had a tendency to produce va- 

 riegated foliage in the gTcenhouse, but when taken to the gardens 

 it l>ecame normal. On the whole, the plants this season were not 

 as showy as their immediate ancestors last year — partly due to the 

 dry weather, but in some measure because of the "dirty" shades 

 of color that came out in the first generation.
