PENTANDRIA— DIGYNIA. Gentiana. 31 



long as the spreading, deeply 5 -cleft, acute, purplish-blue limb, 

 which has no intermediate segments, but the mouth of the tube 

 is crowned with a fine erect purplish fringe, rather shorter than 

 the limb, and rising much above the stamens. The calyx has a 

 turbinate, 5 -angled, pale-green tube, about as long as its 5 

 purplish, lanceolate, acute, erect, smooth-edged segments, 

 which, though uniform, are often a little unequal in size, and 

 reach somewhat beyond the middle of the tube of the corolla. 

 The limb of the latter has occasionally but 4, or even 3, seg- 

 ments, and is never fully expanded but in bright sunshine. The 

 stamens answer in number to the divisions of the cal. and cor. 

 being almost always 5, awl-shaped, with roundish separate 

 anthers. Styles very ahort,. Stigmas ovate. Mr. D, Turner ga- 

 thered on Swaffham heath, some diseased specimens, with dense 

 dark-purple heads, of abortive flower-buds. 



/3, found by the late Sir John Cullum, on a heath between Gran- 

 tham and Ancaster, June 6, 1/74, seems, by his specimens, a 

 dwarf variety, which had survived the winter, nor can it by any 

 specific mark be distinguished from the real Amarella ; which is 

 often seen much more dwarf in autumn, bearing but 1 or 2 

 Jlowers, as represented by Professor Hooker,/. 1. 



G. germanica, Willd. v. 1. 1346, which is G. critica oi Ehrhart, 

 Herb. 152, and, according to Swiss specimens, Haller's n. 651, 

 (though the latter indicates many wrong synonyms, and takes it 

 for an English plant,) difl^ers from Amarella in having powers 

 nearly twice as large, situated about the upper part of the stem, 

 which is of a corymbose form of growth. It may be a good spe- 

 cies, but has not yet been observed in England. Columna's 

 Gentianella purpurea minima, Ecphr. 223. t. 221, copied in 

 Barrel. Ic. t. 97. f. 2. is perhaps different. \{\% Jlowers are 4- 

 cleft, and their calyx has no tube. Barrelier's figures, copied 

 and often perverted, are scarcely to be adjusted to all the known 

 species, and perhaps several still remain undefined, G. germa- 

 nica appears to be a vernal as well as autumnal plant.
