Orobanche minor. Lesser broom rape. Orme's- 

 Head. Diganwy. 



Digitalis purpurea. Foxglove. I cannot help 

 noticing here, although out of place, a curious 

 native variety of this plant, found near Caer- 

 narvon. The petal was divided into five deep 

 segments, and the stamens, instead of con- 

 niving, as usual, stood apart from each other. 

 The buds, on being opened, showed the same 

 iappearance. This fact might afford a curious 

 illustration of the sexual system. A similar 

 instance occurs in another native plant, of the 

 same class and order. Antirrhinum peloria.
