They afterwards only require the culture of 

 being kept free from weeds. 



They are all proper for beina; introduced in 

 the borders or other parts of pleasure-grounds 

 for variety, except the first, which requires the 

 protection of the stove. 



ERYSIMUM, a genus furnishing a plant of 

 the Bowery perennial kind. 



It belongs to the class and order Teir adynamia 

 Biliquasa, and ranks in the natural order of 

 Siliquosee. 



The characters are : that the calyx is a four- 

 leaved perianthium: leaflets ovate-oblong, parallel- 

 converging, coloured, deciduous: the corolla is 

 four-petalled, cruciform : petals oblong, flat, 

 extremely obtuse at the tip : claws length of the 

 calyx, upright : gland nectariferous double, 

 within the shorter filament: the stamina consist 

 of six filaments, length of the calyx ; of these 

 the two opposite shorter: anthers simple : the 

 pistillum is a linear germ, four-cornered, length 

 of the stamens : style very short : stigma head- 

 ed, permanent, small : the pericarpium is a long 

 silique, linear, strict, exactly four-cornered, 

 two-valved, two-celled : the seeds very many, 

 small, and roundish. 



The species principally cultivated is E. Bail 'ci- 

 rca, Winter Hedge Mustard, Cress, or Yellow 

 Rocket. 



It has a perennial root. The stem a foot or 

 eighteen inches high, smooth, round, deeply 

 furrowed, much branched. The leaves smooth, 

 dark green, having two or three pairs of round- 

 ish lobes, connected to a broad foliaceous rib ; 

 the extreme lobe much the largest, and either of 

 an oval or blunt rhomboidal figure, slightly in- 

 dented on the edges; but varying much in form. 

 The flowers are in racemes or thick spikes at the 

 ends of the stem and branches, of a yellow co- 

 lour. It is sometimes cultivated for spring 

 salad, under the name of French or American 

 Cress. 



It varies with double flowers, which is the 

 Double Yellow Rocket. 



Culture. — These plants may be readily in- 

 creased by sowing the seeds in the autumn or 

 spring in the places where they are to remain, 

 afterwards keeping them properly thinned, and 

 clear from weeds. 



The double variety may be propagated by off- 

 sets or slips from the roots, planted out in 

 autumn. 



This species is sometimes sown as a warm 

 spring salad herb. 



The double variety is employed as an orna- 

 mental plant in the borders, &c. 



ERYTHRINA, a genus comprising plants of 

 the herbaceous and shrubby exotic kind. 



It belongs to the class and order Diadvlphia 

 Decandria, and ranks in the natural order of 

 Papilionacece. 



The characters are : that the calyx is a one- 

 leafed perianthium, entire, tubular : mouth cmar- 

 ginate above; beneath furnished with a mellife- 

 rous pore : the corolla papilionaceous, five-pe- 

 talled : standard lanceolate, with sides bent 

 back, ascendin<r, very long : wings somewhat 

 ovate, scarce longer than the calyx, scarce pro- 

 jecting beyond the tube of the standard, very 

 small : keel straight, length of the wings, two- 

 petalled, cmarginate : the stamina consist of 

 ten filaments, conjoined at the lower part, but 

 little hent in, the length of half the standard, 

 unequal : anthers ten, sagittate : the pistillum is 

 a pedicelled germ, subulate, attenuated into a 

 subulate style the length of the stamens : stig- 

 ma terminal, simple : the pericarpium is an ex- 

 tremely long legume, protuberating at the seeds, 

 terminated by a point, one-celled : the seeds 

 kidney-form. 



The species chiefly cultivated are : 1 . E. her- 

 lacea, Herbaceous Coral-Tree; 2. £. carnea, 

 Flesh-coloured Coral-Tree; 3. E. Coralloden- 

 dron, Smooth-leaved Coral-Tree ; 4. E. pkta, 

 Prickly-leaved Coral-Tree. 



The first has a large woody root, from which 

 fresh shoots come out every spring, growing to 

 the height of about two feet, which seldom 

 throw out branches, and are sometimes peren- 

 nial. The leaflets are hastate, deep green ; the 

 upper part of the stalks terminated by a long 

 bunch or spike of scarlet flowers. The legumes 

 five or six inches long, containing five or six 

 scarlet seeds. It flowers in September, but 

 never produces seeds in this climate. It grows 

 naturally in South Carolina. 



In the second species the seeds are not half so 

 large as those of the third, and are of a bright 

 scarlet colour ; the leaves are also much smaller, 

 and have long acute points ; the branches are 

 very closely armed with crooked greenish spines, 

 as are also the ribs and foot-stalks of the leaves. 

 The flowers grow in very long close spikes, and 

 are of a beautiful scarlet colour. It is a native 

 of La Vera Cruz. 



The third has a thick woody stem, which 

 rises about ten or twelve feet high in this cli- 

 mate, but where it is a native to twice that 

 height, sending out many strong irregular 

 branches, which are covered with a brown bark. 

 The leaves are on long foot-stalks ; the middle 

 leaflet much larger than the other two ; they are 

 all heart-shaped, smooth, and of a deep green 

 colour. The flowers come out at the ends of 

 the branches, in short thick close spikes ; arc 

 of a deep scarlet colour, and make a fine ap-
