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 Rev. 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. Gricsbach lays stress on the aestivation of 
the flowers, wdiicli is regularly contorted dextrorsely in G. Amarella, 
but which, he says, is quincuncially imbricated in G. Germanica. 
These characters, how r ever, are evidently of no value. In the speci- 
mens sent by the Rev. Harper Crewe, both forms of aestivation 
occurred on the same plant, and neither form Avas restricted either 
to the terminal or lateral flowers. The capsule being sessile, or 
more or less stipitatc, is another character which has been proposed ; 
but neither form is certainly peculiar to the large- or the small- 
flowered plants.

Tlie 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 bad we no better 
resource.
