Tl'.ty aftcnvards only require tlie culture of 

 being kept tree from weeds. 



Tliev are all proper for being introduced in 

 the borders or other parts of pieasurc-crounds 

 for variety, except the first, which requires the 

 protection of the stove. 



ERYSIMUM, a genus furnishing a plant of 

 the flo\vcr\' perennial kind. 



It belongs to the class and order TclraJi/iiamia 

 Silirpwsa, and ranks in the natural order of 

 Sil'Kfuosce. 



The characters arc : that the calyx is a foiir- 

 leavedperianthium: leafletsovate-oblong, parallel- 

 converging, coloured, deciduous: the corolla is 

 four-pctalTcd, cruciform : petals oblong, flat, 

 extremely obtuse at the tip : claws length of the 

 calyx, upright : gland nectariferous double, 

 T\iihin the shorter filament: tlie stamina consist 

 of six filaments, length of the calyx ; of these 

 the two opposite shorter: anthers simple : the 

 pistillum i? a linear germ, four-cornered, length 

 of the stamens : stvle very short •. stigma head- 

 ed, permanent, small : the pericarpiuni is a long 

 silique, linear, strict, exactly four-comcred, 

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

 small, and roundish. 



The species principally cultivated is E. Barla- 

 rea, 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 Thomboidal 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 Ydlow 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. 



ERYTHHINA, a genus comprising plants of 

 the herbaceous and shrubby exotic kind. 



It belongs to the cla«s and order Diadilphin 

 Dicatnlr'ui, and ranks in the natural order of 

 Pa])iliijnacc(V. 



The characters arc : that the calyx is a one- 

 leafed perianthium, entire, t'-.bular : mouth emar- 

 ginate above; beneath furnished with a mellife- 

 rous pore: the corolla papilionaceous, flvc-pe- 

 talled : standard lanceolate, with sides bent 

 back, ascendinn:, very lone; : \^ings soniewhai 

 ovate, scarce longer than the calyx, scarce pro- 

 jecting hcvond the tube of the standard, verv 

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

 petalled, emarginate : the stamina consist of 

 ten filaments, conjoined at the lower part, but 

 little bent in, the length of half the standard, 

 unequal : anthers ten, sagittate : the pistillum is 

 a pcdicellcd germ, subulate, attenuated into a 

 subulate stvle the leuijth of the stamens: stis:- 

 ma terminal, sunpie : tlie pericarpium is an ex- 

 tTCiuely 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. E. carnea, 

 Fle-)h-colourcd Coral-Tree; 3. E. CoraUoden- 

 dron, Smooth-leaved Coral-Tree; 4. E, p'tcta, 

 Prickly-leaved Coral-Tree. 



The first has a large woody root, from which 

 fresh shoots come out every spring, crowing 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 arc 

 very closely anned with crooked greenish spines, 

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

 The flowers grow in very long close sjiikes, and 

 arc of a beautiful scarlet colour. It is a nati\e 

 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 tluit 

 height, sending out many strong irregular 

 branches, which are covereil with a brown ijark. 

 The leaves are on Ions foot-stalks ; the ;:.iddle 

 leaflet much larger than the other two; they arc 

 all heart-shaped, bmooth, 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-
