 Centaurium, var. 2. <S'm. Fl. Brit. p. 1393. 



On Portmarnock sands growing along with E. Centaurium and is 

 perhaps only a stunted variety of that species, with broader leaves. 

 County of Down ; Mr. Thomas Drummond. Hook. Fl. July. 0. 



3. Gentiana. Linn. Gentian. 



Calyx 4 or 5-cleft. Corolla funnel-shaped or hypocraterifonn, 

 4 or 5-cleft, with the orifice naked. Stamens 5. Stigma 

 2-lobed. Seed not bordered. R. Br. — Named from Gentius, 

 King of Illyria, who, according to Pliny, brought into use 

 the species that is so much valued in medicine as the bitter 

 Gentian, G. lutea. Pentandria. Digynia.

 salver-shaped ; segments auricled at the base ; leaves crowded, 

 ovate. Br. Fl. 1. p. 111. E. Fl. v. ii. p. 29. E. Bot. t. 493. 



In barren mountainous situations on a calcareous soil. Plentiful on 

 the Burren mountains near Gort. On hilly grounds about eight miles 

 west of Tuam, in great abundance ; Mr. John M' Greggor. FL 

 April. %. — Much smaller in all its parts than G. acaulis of the gar- 

 dens and readily distinguished from it by its salver-shaped corolla ; 

 that of the other being subcampanulate, and not found in a wild state 

 in Ireland. Stem shorter, central, leafy, bearing a single flower, with a 

 bright blue corolla. 



2. G. Amarella, Linn. Autumnal Gentian. Corolla salver- 

 shaped, 5-cleft ; bearded in the throat; segments of the calyx 

 nearly equal ; stem flowering from top to bottom, with short 

 axillary branches. Br. Fl. I. p. HI. E. Fl. v. ii. p. 30. E.

 Cave-hill and other places in the County of Antrim. Fl. June 

 — Sept. 0. — From three inches to a foot high, and covered with 

 flowers of a pale purplish blue. 



3. G. campestris, Linn. Field Gentian. Corolla salver- 

 shaped, 4-cleft ; bearded in the throat ; two outer segments of 

 the calyx ovate, very large. Br. Fl. 1. p. 111. E. Fl. v. ii. 

 p. 31. E.Bot. t. 237. 



Hilly pastures, particularly near the coast, most frequent on a lime- 

 stone soil. Fl. Aug. — Oct.©— Very similar to the last in general habit ; 

 but with larger flowers, which are of a paler blue. On the grassy tops 

 of Magilligan rocks, County of Derry, which are composed of basalt, 

 I found in pretty great abundance a variety with white flowers.
