and in the beginning of autumn, removed under 

 the proiection^ol' the greenhouse or garden-frames.^ 



Much caution is necessary in the cuUure of 

 these flowers, not only to choose good seed, but 

 to remove all the bad and imperfect plants as 

 soon as possible from the beds or other places 

 where they are grown. 



The fourth species may likewise be increased 

 by sowing the seeds at different times, as in the 

 above sort, chiefly in the places where they are 

 to flower, and a few in pots for being set out 

 with others of similar growth. 



The fifth sort is propagated and managed in 

 . the same methods as the two first. 



In order to provide good seed of the three 

 first species, great attention should be paid to 

 have it collected from those single plants which 

 have the largest flowers with the deepest and 

 brightest cotours. Some suppose it advantage- 

 ous to take it from such plants as have rather a 

 tendency to the double kinds. The branches 

 should be separated when dry, as the seeds be- 

 come perfectly ripened, and be tied up in small 

 bunches, and hung up in a dry airy situation 

 till the seed is fit to be rubbed out and put up 

 for use. 



In the two last species nothing further is ne- 

 cessary but to take it, when perfectly ripened, 

 from the best plants of the respective kinds. 



All the species and varieties are highly orna- 

 mental, but particularly the double-flowering 

 sorts, being introduced not only in the more 

 open exposures of the clumps and borders of the 

 pleasure-grounds and gardens, where variety is 

 wanted, Ijut in other places contiguous to the 

 house for the delightful smell they afford. 



The last species is sometimes made use of 

 as an edging, and the third as an ornamental 

 plant in windows. • 



CHF^LIDONIUM, a genus furnishing a plant 

 of the hardy herbaceous flowery kind. 



It belongs to the class and order Pohjandria 

 Monogynia, and ranks in the natural order of 

 Rhoeadece. 



The characters are: that the calyx is a two- 

 leaved roundish perianthium : leaflets subovalc, 

 concave, obtuse, caducous: the corolla has four 

 roundish flat petals, spreading, large, narrower 

 at tlie base: the stamina consist of very many 

 filaments (thirty), flat, broader at top, shorter 

 than the corolla: the anthers arc oblong, com- 

 pressed, obtuse, erect, and twin: the pistillum 

 is a cylindric gvrm, the length of the stamens : 

 there is no style : the stigma headed and bifid : 

 thepericarpiumis acylindnc silique, sub-bivalve : 

 the seeds very many, ovate, increased, and shining: 

 the receptacle linear, between the valves of a kind 

 of circumambient suture, not gaping. 



The species worthy of cultivation as an orna- 

 iTK'atal plant is C. glaucum, Sea Celandin?, or 

 Yellow-horned Poppy. 



It has a strong stem : the root-leaves are pin- 

 natifid, waved, variously lobed, and indented; 

 pinnas gradually larger upwards ; hairy on both 

 sides: stem-leaves embracing, deeply indented, 

 rough above, smooth beneath : the branches arc 

 dichotomous: the flowers are of a scarlet co- 

 lour, and succeeded by long horn-shaped pods. 

 The root, according to some, is annual, but 

 others assert it to be perennial. 



Culture. — These plants are raised from seed, 

 which should be sown either in the autumn or 

 spring where the plants are to remain ; or they m.ay 

 be raided in a seed-bed, and be afterwards planted 

 out wheie they are to flower. Some seed should 

 be sown annually, as the plants seldom continue 

 longer than two years. It is hardy, and suc- 

 ceeds in almost any soil or situation. 



The plants afford ornament and variety in the 

 borders both from their flowery nature and the 

 peculiarity of their long-horned pods. 



CHELt)NE, a genus comprehending plants 

 of the flowery herbaceous perennial kind. 



It belongs to the class and order Didyncnnia. 

 Angioipermia, and ranks in the natural order of 

 Personatce. 



The characters are: that the calyx is a one- 

 leafed, five-parted, very short, permanent pe- 

 rianthium : divisions erect and ovate : the co- 

 rolla monopetalous and ringent: tube cylindric, 

 very short: throat inflated, oblong, con\'ex 

 above, flat beneath : border closed, small: upper 

 lip obtuse, emarginate; lower almost equal to 

 the upper, very slightly trifid : the stamina con- 

 sist of four filaments, hid beneath the back of 

 the corolla; the two side ones a little longer : the 

 anthers incumbent: the rudiment of a filth fila- 

 ment, like the point of a dagger, between the 

 upper pair of stamens: the pistillum is an ovate 

 germ: style filiform, situation and length of the 

 stamens: the stigma is obtuse: the pericarplum 

 is an ovate capsule, two celled, longer than the 

 calyx: the seeds very many, roundish, sur- 

 rounde<l with a membranous rim. 



The species cultivated for ornament are : \. C. 

 glabra, White Smooth Chelone; 2. C. oidiqua. 

 Red Oblique-leaved Chelone; 3. C. hirmfa. 

 Hairy Chelone; 4. C. penstemoii, Forking 

 Chelone. 



The first has a pretty thick jointed root, which 

 creeps under ground to a cf.asiderable distance, 

 sending up smooth channelled stalks, w hicli rise 

 about two feet high, with two leaves at each 

 joint, standing opposite without foot-stalks; 

 these are three inrhes and a half long, and about 

 three quarters of an inch broad at their base.
