with slightly reflexed margins. Corolla-tube obconical, much 

 longer than the calyx in flower, and more than twice as long in 

 fruit. 



In chalky places. Rare, and apparently very local. It is not 

 known with certainty to occur anywhere except near Tring ; 

 the only specimens I have seen are from Buckland, in Bucks, 

 and which were kindly sent me by the Bev. Harper Crewe. I 

 have specimens from " Kingston Hill " without the name of the 

 collector. 



England, Ireland ? Annual. Late Summer. 



Gentiana Germanica approaches so nearly to G. eu-Amarella, 

 that it is quite possible it may be merely a variety, and not a hered- 

 itarily distinct sub-species. It is, however, a much more showy 

 plant, with stouter stems, more spreading branches, broader and 

 closer leaves, and very much larger bluish-lilac flowers with a 

 yellowish-white tube, about 1 inch long and f inch across when 

 expanded ; the calyx-segments are of a brighter purple, and one or 

 two of them considerably broader, in this showing some approach 

 to G. campestris. Dr. Griesbach lays stress on the aestivation of 

 the flowers, which is regularly contorted dextrorsely in G. Amarella, 

 but which, he says, is quincuncially imbricated in G. Germanica. 

 These characters, however, are evidently of no value. In the speci- 

 mens sent by the Bev. Harper Crewe, both forms of sestivation 

 occurred on the same plant, and neither form was restricted either 

 to the terminal or lateral flowers. The capsule being sessile, or 

 more or less stipitate, is another character which has been proposed ; 

 but neither form is certainly peculiar to the large- or the small- 

 flowered plants. 



German Gentian. 



French, Genticme d'Allemagne. German, Feld Genziane. 



The Gentian of commerce, which is used in the British Pharmacopoeia, is G. lutea, 

 and has yellow flowers. The properties of the species are more fully developed in it 

 than in our British species, though they might all be used as tonics had we no better 

 resource.
