flowex-ed, leaves elliptical, corolla salver-sliaped 5-cleft with in- 

 termediate small bifid segments, angles of the calyx acute 

 (brown). E. Bot. t. 896. 



Mountains of Scotland, exceedingly rare, having been long gathered 

 only on Ben Lawers, hy Mr Dickson ; but since found abundantly on 

 rocks on both sides of Glen Isla, Clova, by JJr Wight and Dr Graham. 

 Craigalleach, 3Ir F. Adamson. Fl. Aug. .—This rare and beau- 

 tiful little alpine plant varies in height from 1 to 6 inches. 



*** Cor. 4— 5-cleft, someivhat salver-shaped, fringed at the 

 throat. 



5. G. Amarella, L. {autumnal Geiitian); stem very much 

 branched many flowered, leaves ovato-lanceolate, calycine seg- 

 ments nearly equal, corolla 5-cleft. E. Bot. t. 236. 



Pastures, particularly in subalpine situations, England, Scotland, and 

 Ireland : especially abundant in limestone countries. Fl. Apr.— -June, 

 and often through the whole summer and autumn. ©. — From 3 inches 

 to a foot high, branched from the base, and covered \\\\.h floiuers of a 

 pale rather dingy purple. 



6. G. campestris, L. {field Gentian); stem very much branched 

 many-flowered, leaves ovato-lanceolate, 2 outer segments of the 

 calyx very large ovate, corolla 4-cleft. E. Bot. t. 237. 



Hilly pastures, frequent on a limestone or chalky soil in England and 

 Ireland. Abundant in Scotland, especially near the sea. 2^/. Aug. — 

 Oct. .—Flowers larger than in the preceding species, and so nume- 

 rous in specimens gathered on the Isle of Skye that I counted 86__on 

 one plant. 



45. Cuscuta. Linn. Dodder. 



1. C. Europcea, L. (greater Dodder); heads of many flowers, 

 styles included, corolla (in flower) with a cylindrical tube longer 

 than the close-pressed calyx. E.Bot.t. 378. Hook.in Fl. Lond, 

 N. S. t. 67. 



Parasitical on nettles, thistles, &c., not very general. FL Aug., Sept. 

 0. — Sleiris very long, red, having small tubercles or papillae, which 

 serve as roots. Flowers clustered, of a pale yellowish-rose colour. 

 Scales exist in the corolla, according to some aut'hors, but are wanting, 

 according to others. 



2. C. Epilinum, Weihe, (fiax Dodder) ; heads of about 5 

 fleshy flowers, styles included, corolla with a globose tube scarce- 

 ly longer thau the spreading campanulate calyx. Reich. Ic. Bot. 

 t. 500. 



On flax, Ellesmere, J. E. Bowman, Esq. Fl. Aug., Sept. 0.— 

 Stems simple, yellowish-green. Flowers fewer in a head, and much 

 more succulent than in the preceding species, and cellular when seen 

 under a lens. Tube of corolla always globose ; filaments very short. 

 Calyx broad and spreading, with 5 broad acute teeth. — 1 believe this 

 to be quite a distinct species. It is abundant in Germany (whence it 

 was probably introduced with flax-seed to us), and is very injurious to 

 the crops of this plant upon which it is a parasite. 



3. C. Epithymum, L. (lesser Dodder); styles exserted, heads
