11. Rhexia Bivalvis. Smooth, ten-stamined : leaves ob- 

 long, sessile, obscurely cvenate, blunt ; peduncles terminat- 

 ing, one-flowered. This is an annual plant, smooth all over, 

 and of an ash-colour. Native of Guiana. 



12. Rhexia Trivalvis. Smooth, ten-stamined; leaves linear, 

 lanceolate, sessile, dotted above, quite entire; peduncles 

 one-flowered. Annual. Native of Guiana. 



13. Rhexia Longifolia. Hairy, ten-stamined : leaves lan- 

 ceolate, quite entire, five-nerved ; peduncles axillary and 

 terminating, dichotombus, shorter than the leaves. Stems 

 herbaceous, loose, angular, of a yellowish ash-colour, owing 

 to long dense hairs pressed close to the surface. Native of 

 South America.

 colour ; antherse very short. Grows on the bogs of Lower 

 Carolina, and flowers in July and August. 



15. Rhexia Glabella. Plant with a glabrous cylindraceous 

 stem ; leaves sessile, erect, lanceolate, smooth, glabrous, 

 very finely denticulated ; calix glutinous ; flowers the largest 

 of the North American sorts. Grows in the sandy moist 

 woods of Carolina and Georgia. There is a variety with 

 deep purple flowers, called by Walton, Rhexia Alifanus. 



16. Rhexia Stricta. Stem very straight, alate-tetragonal, 

 partially glabrous ; leaves sessile, erect, narrow-lanceolate, 

 attenuate-acuminate, three-nerved, glabrous on both sides ; 

 corymb dichotomous ; calix slightly glabrous ; flowers very 

 handsome, purple. Grows in the bogs of Lower Carolina 

 and Georgia. 



17. Rhexia Lutea. Stem quadrangular, rough; leaves 

 with a few roughnesses ; lower ones cuneate-oblong, obtuse ; 

 upper ones lanceolate ; antherae very short ; flowers small, 

 yellow. Grows in the Pine woods of Georgia and Florida. 



18. Rhexia Linearifolia. Stem cylindrical, subpubescent ; 

 leaves alternate, linear, oblong, obtuse, sessile, pubescent; 

 flowers subsolitary, yellow. Native of Carolina. 



Rhinanthus ; a genus of the class Didynamia, order An- 

 giospermia. GENERIC CHARACTER. Calix: perianth one- 

 leafed, roundish, inflated, compressed, four-cleft, perma- 

 nent. Corolla: one-petalled, ringent; tube subcylindrieal, 

 the length of the calix ; border gaping, compressed at the 

 base ; upper lip galeate, compressed, emarginate, narrower ; 

 lower lip spreading a little, flat, half three-cleft, blunt, the 

 middle segment widest. Stamina: filamenta four, about the 

 length of the upper lip, under which the two shorter ones 

 lie concealed , antherse incumbent, bifid on one side, hirsute. 

 Pistil: germen ovate, compressed ; style filiform, in the same 

 situation with, but longer than the stamina; stigma blunt, 

 bent in. Pericarp: capsule blunt, erect, compressed, two- 

 celled, two-valved, opening at the edges ; partition contrary. 

 Seeds: several, compressed. Observe. The second species 

 has the margin of the capsule blunt, the seeds simple, the 

 calix unequal, two-lipped. .The margin of the capsule in 

 the third species is augmented, the seeds membranaceous, 

 clothed with wool, and the calix equal, four-cleft. ESSENTIAL, 

 CHARACTER. Calix: four-cleft, ventricose Capsule: two- 

 celled, blunt, compressed. The plants of this genus do not 

 thrive under culture, and are very difficult to keep in gardens. 

 Being annual, they can only be propagated by seeds, which 

 should be sown soon after they are ripe wherever they are 

 intended to remain, as they will not bear removing. They 

 require a moist rich soil, and a shady situation. When the 

 plants come up, thin (hem, and keep them clear from weeds 

 If the seeds be permitted to scatter, the plants will come up 



better than when sown by hand ; but they thrive best among 

 "rass. The species are, 



1. Rhinanthus Orientalis. The corollas with the upper lip 

 awl-shaped, and curved in ; stems a foot and a half high, 

 lollow, four-cornered, hairy. The flowers on the upper part 

 of the stem yellow, with a brown spot on the lower lip, and two 

 red ones on the upper : they have an agreeable scent. Tourne - 

 'ort, who found this plant on the confines of Persia, flowering 

 n July, speaks of it as one of the most beautiful in the East. 



2. Rhinanthus Elephas. The corollas with the upper lip 

 awl-shaped, straight. Native of Italy and Siberia, in shady 

 places, flowering in May. 



3. Rhinanthus Crista Galli; Yellow Rattle, or Cock's Comb. 

 Upper li-p of the corolla arched ; calix smooth ; leaves lan- 

 ceolate, serrate. Root annual, small, with few fibres ; stem 

 Dranched, smooth, frequently spotted; flowers not always 

 strictly opposite, on short peduncles, yellow. It flowers 

 early in June, and is common in pastures ; and is called Yel- 

 low P. attle from the noise made by the ripe seeds in the calix. 

 It is known in some counties by the name of Penny Grass, 

 and in Yorkshire by that of Henpenny, from the size and 

 shape of the seed-vessel, like a silver penny. Its other 

 appellation, of Cock's Comb, is derived from the appearance 

 of the upper leaves or bractes which accompany the flowers. 

 Horses, sheep, and goats, are said to eat it, and cattle to 

 refuse it; though others say, that all quadrupeds reject it 

 except when in the stall or stable, or given dried as hay. 

 The growth of this plant is remarkably quick, and is sup- 

 posed in some foreign countries to be very injurious to the 

 crop of Rye. It is a troublesome weed among grass, inso- 

 much that in many water meadows there is more of this plant 

 than of herbage. The seed ripening by the time these mea- 

 dows are commonly mowed, the seeds scatter, and fill the 

 ground with young plants in the following spring. In order 

 to destroy it, the grass among which it grows ought to be 

 cut as soon as the flowers appear; and those who purchase 

 Grass seeds should be careful that none of this seed be mixed 

 with it. 



4.. Rhinanthus Trixago. Calices hirsute, tomentose ; leaves 

 opposite, bluntly serrate ; stem quite simple ; root annual, 

 throwing out runners ; flowers in large yellow spikes. Native 

 of Italy, the south of France, and Palestine. 



5. Rhinanthus Capensis. Calices tomentose; bractes 

 ovate ; leaves lanceolate, toothed. Native of the Cape. 



6. Rhinanthus Trifida. Corollas spreading at the throat ; 

 leaves trifid. Root annual; stem upright, quite simple, six 

 inches high, herbaceous. Native of sandy hills in Armenia 

 and Galatia. 



7. Rhinanthus Indica. Leaves sublanceolate, hairy, quite 

 entire. Native of Ceylon. 



8. Rhinanthus Virginicus. Corolla spreading &t the throat ; 

 leaves smuated and toothed ; anthers rough with hairs. 

 Native of Virginia. 



Rhizobolus ; a genus of the class Polyandria, order Tetra- 

 gynia. GENERIC CHARACTER. Calix: perianth one-leafed, 

 fleshy, tomentose, half five-cleft; segments roundish, con- 

 cave. Corolla: petals five, ovate, rounded, concave, fleshy, 

 inserted below the divisions of the calix, and much larger 

 than it. Stamina: filamenta very numerous, filiform, longer 

 than the corolla, inserted into the receptacle; antheree 

 roundish. Pistil: germen superior, four-cornered, at the 

 bottom of the calix; styles four, filiform, longer than the 

 corolla; stigmas blunt. Pericarp: drupes four, kidney- 

 shaped, compressed, inserted by the internal wedge-form 

 margin into a conical receptacle, one-celled, with a fleshy 

 rind, and a buttery soft pulp. Seeds: nuts solitary, kid-
