pointing one way, nodding a little at top, in pairs or single, 

 on short peduncles ; calix hairy on the outside, the teeth 

 equal and sharp; corolla dusky red or purple, sometimes 

 varying to white, hairy, very differently formed from the pre- 

 ceding, the upper lip being compressed, and scarcely emar- 

 ginate, the, three lobes of the lower lip shorter than the upper, 

 equal, truncate, crenulate ; all tlie lobes of the antheree are 

 thorny at the tip, and bearded at the base; at the back, 

 where the filament is inserted, are several small club-shaped 

 threads or appendages ; seeds ovate, very white, with a mem- 

 branaceous margin on one side, elegantly latticed, with lon- 

 gitudinal ridges, and similar transverse streaks. It is com- 

 mon both in corn-fields and pastures, especially those that 

 are moist, and flowers from July to September. 



5. Euphrasia Lutea; Yellow Eyebright. Leaves linear, 

 serrate, the upper ones quite entire. This resemWes the 

 fourth species, but differs from it in having yellow flowers; 

 the upper lip bearded or villose within and without, and 

 emarginate; the lower lip concave, trifid, with the segments 

 equal; stem one, seldom more, rough, hard, woody, upright, 

 \vaudlike, dusky red ; style yellow ; stigma simple, both per- 

 manent; antheroe beardless; capsule smooth, and green at 

 bottom, at top villose, blackish-red; seeds brown, oblong. 

 Native of Switzerland, Savoy, Austria, Fritili, Silesia, the 

 Palatinate, Piedmont, Tuscany, and the south of France. 



6. Euphrasia Linifolia; Flax-leaved Eyebright. Leaves 

 linear, all quite entire; calices smooth. This is a little stiff, 

 narrower, finer, but frequently higher, than the common 

 sort; the leaves are entire; the flowers yellow. Native of 

 France and Italy. 



7. Euphrasia Viscosa ; Clammy Eyebright. Leaves linear ; 

 calices glutinous-hispid. This plant is described by Gouan 

 to be only three inches high, and simple, or a foot high and 

 branched, smooth or villose. All the leaves are broader at 

 the base, thence gradually attenuated, and rough with hairs, 

 most frequently quite entire, but sometimes toothed, the 

 lower ones are opposite, the rest alternate, whence the 

 branches themselves are seldom opposite ; flowers on a very 

 short peduncle, alternate, each within a single bracte. 

 Native of Provence, Dauphiny, Switzerland, Savoy, Pied- 

 mont, and the county of Nice. 



8. Euphrasia Cuneata ; Wedge-leaved Eyebright, Leaves 

 somewhat wedge-shaped, gashed. Native of New Zealand. 



9. Euphrasia Longiflora ; Long-flowered Eyebright. Pu- 

 bescent, viscid : leaves linear, quite entire ; tube of the co- 

 rolla filiform, three times as long as the calix. Cavanilles 

 describes the stem as a foot high, of a dark red colour ; the 

 branches decussated and four-cornered. Flowers axillary, 

 in spikes ; calix cut half way ; tube of the corolla half an inch 

 long, lower lip broader, with rounded segments; filaments 

 short, fastened to the upper part of the tube, within the 

 upper lip; antheree ovate, twin, two-awned at the base, and 

 perforated ; style red, the length of the corolla ; stigma cliib- 

 shaped; seeds longitudinally streaked.- It flowers in Sep- 

 tember, in Spain, where it is a native, having been found 

 there, near Espexa, Rivas, and in the kingdom of Arragon. 



Eurya; a genus of the class Dodecandria, order Monogy-' 

 nia. GENERIC CHARACTER. Calix: perianth five-leaved; 

 leaflets ovate, concave, obtuse, smooth, surrounded at the 

 base with a two-leaved similar calicle, one-third only of the 

 size of the calix. Corolla: petals five, roundish-ovate, con- 

 cave, the size of the calix; nectary, dots on a purple rim, at 

 the base of the filamenta. Stamina: filamenta thirteen, very 

 short, so as to be scarcely any; antherae upright, four-sided, 

 almost the length of the corolla. Pistil: germen superior, 

 convex, smooth ; style subulate, shorter than the antheree;

stigmas three, reflex. Pericarp: capsule globular, with the 

 style permanent, sharp, smooth, five-celled, five-valved. 

 Seeds : somewhat three-cornered, dotted, very many. 06- 

 sene. The flowers seem very frequently to be dioecou9. 

 ESSENTIAL CHARACTER. Calix : five-leaved, calicled. Co- 

 ro/la : five-petalled. Stamina: thirteen. Capsule: five-celled.
