Note. — A form witli very double flowers is somewhat frequent upon Keep Hill. 

 /3 G. germanica, Willd. With G. Amaixlla, and equally frequent. 



Note — Specimens of this plant from Keep Hill, etc., agree perfectly with otheriS, 

 kindly forwarded to me by the Eev. H. H. Crewe, from Buckland, Bucks (the locality 

 from which the specimen figured as G. germanica, in Journal of Botany, ii. tab. 15. 

 was taken). It is difficult to set down on paper any characters by which G. germanica 

 may be separated from G. Amarella, although the two forms are very different in gene- 

 ral appearance ; G. germanica being much larger than G. Amarella in all its parts, 

 especially in the flowers, which are also more distinctly funnel-shaped, and usually of •:' 

 different shade of purple. The stalked capsule occurs in both forms, and is valueless a 

 a distinguishing mark. Both usually occur together ; although in some places, as b: 

 the roadside from West Wycombe to Rledlow Eidge, and along the hill side between tli 

 Ridge and the Union House, G. Amarella only appears. It seems best to regard bot' 

 as forms of one species.
