perennial; stems a long span in height, slender; leaves quite 

 entire, narrow and sharp, villose and glutinous; peduncles 

 alternate, one-flowered, few in number; semiflorets twenty and 

 more in a flower, purple. Native of the south of France and 

 Spain, on mountains near the sea-coast. It flowers in August. 



4. Erigeron Siculum ; Red-stalked Erigeron. Lower ca- 

 licine scales loose, longer than the flower; peduncles leafy; 

 stems red ; flowers without any ray, small ; peduncles co- 

 vered with linear, recurved, minute leaves. Annual. Found 

 in Sicily, and about Montpellier, in marshes. It flowers in 

 August and September. 



5. Erigeron Carolinianum ; Carolina Erigeron. Stem pa- 

 nicled ; flowers subsolitary, terminating; leaves linear, quite 

 entire. Stems three feet high and more, straight, round, 

 streaked, the thickness of the little finger at bottom, where 

 they are red, growing gradually more slender upwards; the 

 leaves from top to bottom are frequent, very narrow, and 

 somewhat hairy: towards the top the stem puts forth branches, 

 forming in the whole a sort of pyramid ; these are covered 

 with leaves, like those of the stem, only shorter and narrower ; 

 each of these bears one small flower, sometimes more ; the 

 root-leaves are like those on the stem, only shorter and blunter. 

 Perennial. It is a native of North America, and hardy enough 

 to flower in the open ground, in July and August. 



6. Erigeron Canadense ; Canadian Erigeron. Flowers in 

 panicles, hairy, rough ; leaves lanceolate, cihate ; root annual ; 

 stem firm, hairy, sometimes three or four feet high, frequently 

 crooked, much branched towards the top, and even from the 

 middle; the branches gradually shorter, and forming a long 

 cone; flowering-heads numerous, or simple, on branched 

 slender peduncles; florets very small. It came originally 

 from North America, but now has the appearance of being 

 indigenous in many parts of Europe; it is not uncommon 

 about London, and in Glamorganshire, on cultivated grounds, 

 and on rubbish. It flowers in August. Petivers calls it 

 White Golden Rod. This, with the seventh, thirteenth, and 

 fourteenth species, are preserved in botanic gardens for the 

 sake of variety, but are seldom admitted into gardens for 

 pleasure. 



7. Erigeron Bonariense; Buck's-horn Erigeron. Leaves 

 rolled back at the base. Root annual ; stem angular, firm, 

 hirsute, branched at top ; leaves alternate, lanceolate, hirsute, 

 and soft, sessile, the lower ones tooth-gashed, the upper entire, 

 narrower, and almost linear, towards the base waved, the 

 midrib more prominent and hirsute ; flowers on the top of the 

 stem, and at the extremities of the branches. It flowers in 

 July and August, and is a native of Buenos Ayres, in South 

 America. It is an annual plant, and, like the thirteenth spe- 

 cies, when once admitted into a garden, and suffered to scat- 

 ter its seed, will become a very troublesome weed, although 

 it is very serviceable to cover rubbish or rock-work. 



8. Erigeron Jamaicense ; Jamaica Erigeron. Stem few- 

 flowered, subvillose ; leaves wedge-form, lanceolate, with two 

 serraturcs on each side. Root almost single, but sometimes 

 subdivided, descending ; stems erect, or ascending, often a 

 span high, filiform, pubescent, almost single; flowers sub- 

 solitary, terminating, peduncled, whitish ; those on the top 

 of the stem resemble Groundsel flowers, composed of many 

 small yellow florets set close together, encircled by many 

 whitish, long, narrow semiflorets. Native of Jamaica. 



9. Erigeron Philadelphicum ; Spreading Erigeron. Stem 

 many-flowered ; leaves lanceolate, subserrate, those on the 

 stem half stem-clasping; floscules of the ray capillaceous, 

 the length of the disk : perennial. It flowers from June to 

 August, and is a native of North America, where it was ob- 

 served, as well as in Canada, by Kalin.

10. Erigeron Purpureum; Purple Erigeron. Stem many- 

 flowered, hairy; leaves oblong, somewhat toothed, stem- 

 clasping; corollas of the ray capillaceous, longer than the 

 disk. Root perennial ; stem herbaceous, branched, a foot or 

 more in height; flowers panicled ; corollets of the ray very 

 numerous, purple, of the disk yellow. It flowers in July and 

 August, and is a native of Hudson's Bay. 



11. Erigeron ./Egyptiacum ; Egyptian Erigeron. Leaves 

 half stem-clasping, spatulate, toothed; flowers globular. Root 

 annual; stem simple, upright, a foot and half high, somewhat 

 streaked, ash-coloured, pubescent, and somewhat viscid; 

 flowers panicled, terminating, four or five, peduncled, round- 

 ish, on purplish peduncles; corolla florets minute, those in 

 the ray naked and abundant; style cloven, yellow, capillary, 

 quickly disappearing. Native of Sicily and Egypt. 



12. Erigeron Gouani ; Cluster-flowered Erigeron. Flowers 

 heaped ; calices scariose ; leaves lanceolate, somewhat tooth- 

 ed, scabrous about the edge. Root annual, bitter; stem 

 upright, round, a foot high, simple, with a few upright hairs ; 

 flowers panicled ; corollas whitish, with white down ; calix 

 roundish, imbricate; scales lanceolate, naked, convex, close, 

 scariose about the edge, bluntish, not patulous, with a 

 subulate tip. It flowers in July and August. Native of the 

 Can?ry Islands. 



13. Erigeron Acre ; Blue Erigeron, Peduncles alternate, 

 one-flowered ; root perennial, or, according to some, biennial, 

 fibrous, acrid ; stems from six to eighteen inches high, up- 

 right, somewhat angular, hairy, often purple, in some scarce 

 branched at all, in other plants very much so. The upper 

 part of the stem is divided into alternate branches, each bear- 

 ing a single flower, which never expands, and is externally 

 purple, but internally yellow, with a cavity in the middle. 

 It is often found in dry lofty pastures, especially in sandy 

 and calcareous soils, and upon old walls. It has been found 

 growing at the Block-house at Gravesend, and near Charlton 

 wood, but is not often seen near London. It flowers from 

 July to September. Cows and goats refuse to eat it. The 

 Germans take a decoction of it to attenuate viscid phlegm. 

 English botanists have named it Blue-flowered or Purple 

 Fleabane, which name is also applied to several other of this 

 genus, and tends very much to confound it with the genus 

 Conyza, to which the intelligent reader is referred. 



14. Erigeron Alpinum; Alpine Erigeron. This so strongly 

 resembles the preceding species, that Haller suspects it to be 

 only a variety. It has frequently a higher stem, but the height 

 varies much in both-; the flowers are larger, the semiflorets 

 more numerous, the leaves longer, the feather dense and 

 whitish. Native of Alpine pastures. Found on Ben Lawers, 

 and other high mountains in Scotland. Perennial ; flower- 

 ing in July and August. It may be propagated by seeds, in 

 a shady situation and moist soil. See the first species. 



15. Erigeron Uniflonim; Dwarf Erigeron. Stem one- 

 rlowered ; calix hairy. Root perennial ; stems a finger's length ; 

 leaves few, lanceolate, almost smooth on the upper surface, 

 but with spreading hairs scattered over the lower; the stem- 

 leaves often sublinear, the root-leaves oblong. The flower is 

 as large as in the foregoing species, thick ; the scales covered 

 with a white nap, lanceolate, broader ; all the semiflorets 

 ligulate, with no imperfect ones, sometimes purple. All the 

 varieties with one and many flowers, with a smooth and hairy 

 calix, with blue and white flowers, make but one species. It 

 flowers in August and September; and is a native of the 

 European mountains, from Lapland to Italy. 



16. Erigeron Gramineum ; Grass-leaved Erigeron. Stem one- 

 flowered ; leaves linear, ciliate, scabrous. This is a small peren- 

 nial plant, guarded with fadingdry leaves.- -Native of Siberia.
