1. G. Amarella (L.); cor. salvershaped 4—5-cleft bearded in 
the throat, cal.-lobes 5 nearly equal lanceolate, 1. sessile ovate-lan- 
ceolate, radical 1. obovate.—H. B. 236.—Very variable in size and 
in the number of the flowers, 3-12 in. high, erect. St. square, 
much branched. Fl. pale purple.—Grisebach distinguishes G. 
germanica by its acuminate calyx-lobes, obconical tube of the co- 
rolla, and stalked capsules; G. Amarella by its obtuse calyx-lobes, 
cylindrical tube of the corolla, and sessile capsules. Both are na- 
tives of Brita, but their claims to distinction are very doubtful.
