The first three sorts afford an agreeable varicly 

 in ilie borders and chimps, as they continue long 

 in flower. The four following kinds are likewise 

 hardv, and afford variety among other potted 

 plants in the open air during the summer. 



Tlie other species are more tender, but pro- 

 duce an agreeable effect among the stove and 

 sireen-house collections, from the greatbeanty and 

 continuance of the fiowers in many of ihe sorts. 



ERICiHRON, a genus comprising plants of 

 thehardv herbaceous perennial kind. 



It belones to the class and order Si/?igenesia 

 Poliigamla^Siipeif iin , and ranks in the natural 

 order oi Covipnsitce Discoidcce. 



The characters are : that the calyx is common 

 oblong, cylindric, imbricate: scales subulate, 

 upright, gradually longer, nearly equal : the 

 corolla compound rayed : corollets hermaphro- 

 dite, tubular in the disk ; females ligulate in the 

 rav ; proper of the hermaphrodite funnel-form ; 

 border five-cleft : of the female ligulate, linear, 

 subulate, upright, commonly quite entire: the 

 stamina in the hermaphrodites have five fila- 

 ments, capillary, very short : anthers cylindric, 

 tubular : the pistillum in the hermaphrodites ha* 

 the germ very small, crowned with a down longer 

 thaiT its corollet: style filiform, length of the 

 down : stigmas two, very slender : there is no 

 pericarpium : calyx converging: the seeds in 

 the hermaphrodites oblong, small : down long, 

 hairy : of the females extremely like the herma- 

 phrodites : the receptacle naked, and flat. 



The species mostly cultivated are : \. E. vis • 

 cosum. Clammy Erigeron ; 2. E. Canaderise, 

 Canadian Erigeron ; 3. £. pJirpureum, Purple 

 Erigeron, or Labrador Aster. 



Other species may be cultivated for variety. 



The first has an upright, stiff" stem, near three 

 feet high, striated, hairy, viscid, branched from 

 the very" bottom : the leaves thick, rough with 

 hairs, having glands between them exsuding a 

 clammy juice, strong smelling, bent down at 

 the base, rounded and stem-clasping : on the 

 branches linear, entire, four inches long and two 

 broad : the peduncles two-leaved, one-flowered ; 

 scarcely longer than the leaves : flowers radiate, 

 of a yellow colour ; appearing in July, and af- 

 fording an agreeable smell. It is a native of 

 the South of France, &c. 



- The second species has an annual root: the 

 <item firm, hairy, sometimes three or four feet 

 high, frequently crooked, much branched to- 

 wards the top, and even from the middle : 

 the branches gradually shorter, and forming a 

 long cone : the lower leaves oval, tapering to a 

 foot-stalk, with large blunt distant teeth; higher 

 lip lanceolate, distinctly serrate, (or entire) 

 slightly hairy on the upperj but more so on the 



lower surface, those on the branches and at their 

 base linear-lanceolate, entirely sessile: flowering- 

 heads numerous, on simple or branched slender 

 peduncles. It came originally from North 

 America, flowering in August. It is sometimes 

 called White Golden RodT 



The third has a perennial root: the stem her- 

 baceous, branched, a foot or more in height : 

 the leaves alternate, sliarp, either entire, or with 

 a few teeth about the edge : the flowers panicled : 

 leaflets of the calyx lanceolate, sharp, unequal, 

 smooth, sliohtly keeled ; the keel having a few 

 hairs scattered over it : corollets of the ray very 

 numerous, purple; of the disk yellow. It is a 

 native of Hudson's Bay, flowering in July and 

 August. 



Culture. — These plants may be increased by 

 sowing tbesccds in patches, in the perennial sorts 

 in the autumn, and the annual ones in the spring, 

 in the borders, clumps, or other parts where the 

 plants are to remain. They should afterwards 

 be kept free from weeds, and be properly 

 thinned. 



The perennial kind iriay likewise be increased 

 by off-sets or slips from the roots, which should 

 be planted out in the autunm, where the plants 

 are to continue. 



The first kind requires a dry soil and sunny 

 exposure. The perennial sort flowers the se- 

 cond year. 



They are plants which afl^ord ornament and 

 variety among other? of the flowering kind. 



ERINGO. See Eryngium. 



ERINUS, a genus comprising plants of the 

 herbaceous and shrubby perennial kind. 



It belongs to the class and order Didytuimia 

 Ang'wspermia, and ranks in the natural order of 

 PersonatcB. 



The characters are : that the calyx is a five- 

 leaved perianthium : leaflets lanceolate, upright, 

 nearlyequal, permanent: the corolla one-petailed, 

 unequal : tube ovate-cylindric, length of the 

 calyx, bent back: border flat, five- parted: di- 

 visions equal, obcordate : the stamina have four 

 filaments, very short, within the tube of the 

 corolla, of which the two opposite ones are 

 a little longer: anthers small : the pistillum is a 

 somewhat ovate germ : style very short : stigma 

 headed : the pericarpium is an ovate capsule, 

 rolled up in the calyx, two-eellcd, gaping two- 

 wavs : the seeds nurnerous and small. 



The species are; 1. E. Alplnus, Alpine Eri- 

 nus ; 2. E.fragrans, Sweet-smelling Erinus. 



Other species may be cultivated for variety. 



The first has a perennial root : the root-leaves 

 form a thick tuft close to the ground, are all line- 

 ar-spatulate, pubescent, with a few serratures at 

 the end on both sides : the leaves on the stem
