GENTIANEjE. 
4. E. linarifolia (Pers.) ; st. simple solitary or several from 
the crown of the root, 1. oblong-linear obtuse narrowed below, 
radical 1. crowded spathulate, fl. sessile densely corymbose, calyx 
as lovy as the- tube of the opening corolla, lobes of the cor. oval 
obtuse.— E. lateralis Hook. E. B. 2305.— St. 2—6 in. high, 
solitary or several, simple, with scabrous angles. Inflorescence 
usually trichotomous, dense, branches sometimes elongated. Ra- 
dical 1. only slightly larger than those of the stem, numerous. — 
Sandy sea-shores. A. VII. VIII. 
3. Cicendia Adans. 
1. C. filiformis (Reich.) ; cal. half tubular adpressed to the 
subglobose tube of the corolla, lobes ovate acute, st. thread- 
shaped forked, fl. solitary on long stalks. — Exacum Sm. E. B. 
235. Gentiana Koch. — St. very slender, 1 — 4 in. high. Radical 
1. linear-lanceolate, stem 1. subulate, all sessile. Fl. yellow. 
Caps, with the edges of the valves not inflexed. — Damp sandy 
places. A. VII. VIII. E.I. 
Tribe III. Swertice. 
4. Gentiana Linn. 
1. G. Amarella (L.) ; cor. salvershaped 5-cleft bearded in the 
throat, cal. -segments 5 nearly equal linear-lanceolate, 1. sessile 
ovate-lanceolate; radical 1. obovate. — E. 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 distin- 
guishes G. germanica from this by its acuminate calyx lobes, ob- 
conical tube of the corolla, and stalked capsules. In all these 
points (which I fear are not constant) my British specimens 
agree better with G. germanica than G. Amarella, which possesses, 
according to that author, obtuse calyx lobes, a cylindrical tube 
to the corolla, and sessile capsules. He refers to both plants as 
being natives of Britain. Reichenbach adds as a character of 
G. gei-manica revolute margins of the calyx-segments. It appears 
to me that these 2 and also G. obtusifolia (Willd.) form only one 
species. See Trans. Bot. Soc. Edin. i. 59- and Phyt. i. 381. — 
Dry calcareous fields. A. VIII. IX. 
2. G. campestris (L.) ; cor. salvershaped 4-cleft bearded in the 
throat, cal. -segments 4, 2 outer ones very large ovate, 1. elliptic- 
oblong.— E. B. 237 — St. 3—10 in. high. Fl. blue, tube of the 
corolla slightly thicker upwards. Caps, nearly sessile. — Dry 
limestone hills. A. VIII. IX. 
3. G. nivalis (L.) ; cor. salvershaped 5-cleft with minute in- 
termediate bifid segments, throat naked, cal. cylindrical with 5 
keeled angles, I. ovate lowermost broadly elliptical. — E. B. 896.
