toothed. It varies with subserrate leaves and small flowers. 

 Linneus observes, that the calix and structure of this plant 

 makes -it very nearly allied to the Aster ; and that it is 

 covered with a snowy-white pubescence. Native of Spain, 

 and of the country about Montpellier and Vienna; and in the 

 southern part of Dauphiny; near Turin, and in other parts 

 of Sardinia ; in the vineyards of the Palatinate ; and in Swit- 

 zerland, and the Valais. It flowers in July and August, but 

 will rarely ripen seed here. 



26. Inula ^Estuans. Leaves spatulate, tomentose under- 

 neath. Native of South America. 



27. Inula Bifrona. Leaves decurrent, oblong, toothletted; 

 flowers heaped, terminating, subsessile. Stem a foot high, 

 somewhat rigid, corymbed, with a strong smell like Tansy ; 

 flowers yellow, with a short ray. Biennial. ' It flowers in 

 July and August, but never perfects seeds in this country. 

 Native of Italy, Provence, and the Pyrenees. See the 

 13th species. 



28. Inula Coerulea; Blue-flowered Inula. Leaves decur- 

 rent, obovate, subserrate ; stem suffruticose ; flowers sessile, 

 terminating. Though this has a blue ray to the flower, in 

 which it differs from all the Inulas, yet its appearance or 

 habit is quite foreign to that of the genus Aster. The 

 branches are one-flowered. Native of the Cape of Good 

 Hope : annual. This, and the two following, may be increased 

 by cuttings, and must be kept in the dry stove. 



29. Inula Aromatica; Aromatic Inula. Leaves linear, 

 quite entire, tomentose, scattered ; stem shrubby. Flowers 

 solitary, terminating, sessile ; ray of the flower pale whitish 

 flesh-colour. Native of the Cape. 



30. Inula Pinifolia : Pine-leaved Inula. Leaves subulate, 

 linear, three-sided, clustered very much ; stem shrubby, half 

 a foot high, verry rugged with the fallen leaves. Native of 

 the Cape. 



31. Inula Foetida; Stinking Inula. Leaves lanceolate- 

 linear, quite entire ; corymbs branched ; rays of the flower 

 very short. Stems several, a foot high, straight, branched, 

 rough with harsh hairs; leaves hirsute, not unlike those of 

 Hyssop ; flowers golden-coloured. Native of Malta. 



32. Inula Canariensis ; Canary Inula. Leaves linear, 

 fleshy, three-cusped ; stem shrubby. This rises with several 

 shrubby stalks, near four feet high; which divide into smaller 

 branches ; leaves in clusters, narrow, fleshy, divided into 

 three segments at their points. The flowers come out on the 

 side of the branches at the top of the stalks, and are small, 

 and of a pale yellow, appearing in August. Native of die 

 Canary Islands. It will not bear the open air in our winters, 

 and must be removed into shelter in autumn, but still have as 

 much free air as possible in mild weather, that it may not be 

 drawn up weak. They must have very little water in cold 

 weather ; as their stalks and leaves are succulent, they are 

 very apt to rot. In summer they should be placed abroad, 

 with other hardy exotic plants, in a shaded situation, where 

 they will add to the variety, though they seldom flower except 

 in very warm summers. They are easily propagated by cut- 

 tings planted during summer in a shady border, where they 

 will take root in a short time. 



33. Inula Satureioides ; Savory-leaved Inula. Leaves 

 linear, hirsute, opposite; peduncles naked, one-flowered. It 

 rises with a shrubby stalk nearly two feet high ; at the ends 

 of the branches arise naked peduncles, four or five inches 

 long, sustaining one small yellow radiated flower. Found at 

 La Vera Cruz. It is propagated by cuttings during the summer 

 season, which must be planted on a bed of light earth, and 

 shaded till they have taken root; after which, the plants must 

 be treated in the same manner as other hardy exotics. 



34. Inula Fruticosa; Shrubby Inula. Leaves lanceolate, 

 acute, three-nerved underneath; calicine scales acute; stem 

 shrubby. Stem ten or twelve feet high, divided into several 

 woody branches ; at the ends of which the flowers are pro- 

 duced ; they have very large scaly calices, are as large as a 

 small sun-flower, and" of a pale yellow colour. Native of 

 Carthagena in New Spain. This is too tender to bear the 

 open air of England, and must be constantly kept in the bark- 

 stove. It is propagated by seeds, which must be procured 

 from the country where it naturally grows, for it does not pro- 

 duce any here. The seeds must be sown upon a hot-bed, 

 and when the plants are fit to remove, they should be each 

 put into a small pot filled with light earth, and plunged into 

 a fresh hot-bed ; treating them in the same manner as other 

 tender plants from the same country. 



35. Inula Graminifolia. Stalk very simple; leaves lan- 

 ceolate, linear, very entire, erect, nervose ; corymb com- 

 pound, lax ; calices turbinate. It rises a foot high, with 

 small flowers. Found in the sandy woods from Pennsylva- 

 nia to Florida.

1. Joncquetia Guianensis. This is a very large tree, with 

 a trunk forty or fifty feet high, and two or three feet in dia- 

 meter, with a smooth russet bark, and a white uncompact 

 wood. It has a great number of branching boughs at top, 

 those in the middle erect, the rest horizontal and spreading 

 in all directions. Leaves alternate, unequally pinnate; leaf- 

 lets in three, four, or five pairs ; petiole almost cylindric, 

 eight or nine inches long, fleshy at the base; flowers small,
