be taken not to break them in removing. They will thrive 

 in almost any soil or situation ; and will flower even in Lon- 

 don, better than most other plants. If they be once intro- 

 duced, and permitted to scatter, there will be a supply of 

 plants witliout any care. 



2. CEnothera Grandiflora ; Great-flowered Tree Primrose. 

 Leaves ovate-lanceolate; (lamina declined; stem 'shrubby. 

 Biennial, flowering in July and August. Native of North 

 America. This, and the fifth, sixth, and seventh species, 

 are commonly considered as green-house plants, though they 

 produce flowers and seeds in the open air, and are therefore 

 seldom preserved. -3 g c]3 j,{ afaJ[r3 rltot 



3. CEnothera Parviflora ; Small-flowered Tree Primrose. 

 Leares ovate-lanceolate, flat; stem even, subvillose. It does 

 not rise so high as the first species, the leaves are narrower, 

 and the flowers smaller. Native of North America. 



4. CEaothera Muricata; Muricated Tree Primrose. Leaves 

 lanceolate, flat; stem purple,, muricated. Native of Canada. 



<(j f 6. CEnothera Longiflora; Lony-flvwered Tree Primrose. 

 Leaves toothletted ; stem simple, hairy ; petals distant, two- 

 lobed; root biennial; root-leaves numerous, broad-lanceolate, 

 teothietted, pubescent, with a white rib, obliquely nerved. 

 Mr. Curtis remarks, that luxurious specimens of this plant 

 exceed five feet in height ; that the flowers are uncommonly 

 large and showy, and continue blowing from July to October. 

 Native of South America. The plant is annual, of ready 

 growth, and very productive of seeds, t -which ripen early. 

 Sow them in the open border, where they are intended to 

 flower, in March, or the beginning of April. A. single plant 

 is sufficient for one spot. Put a stick of four feet long to it 

 when young, and tie up the branches to the stick when they 

 are about a foot long. 



6. CEnothera Mollissima ; Soft Tree Primrose. Leaves 

 lanceolate, waved, pubescent, very soft ; stalk shrubby, more 

 than two feet high, hairy ; flowers axillary like the other 

 sorts, at first pale yellow, but as they decay changing to an 

 orange colour. It flowers from June to October. Biennial. 

 Native of South America. Propagated like the first species. 



7. CEnothera Rosea ; Rose-flowered Tree Primrose. Leaves 

 ovate-toothed; lower ones lyrate ; capsules club-shaped. 

 It rarely lexceeds a foot in height; its rose-coloured flowers 

 expand during the whole of the day, and are produced dur- 

 Mig most of the summer months. This, and the next species, 

 may be increased either by cuttings or seeds. This species 

 produces abu/idancp of seed, which should be sown in the 

 spring with tender annuals : when the plants have acquired 

 a proper age, and the season is favourable, plant them out 

 singly in the open border. 



8. (Enothera Purpurea ; Purple Tree Primrose. Leaves 

 ovate, lanceolate, glaucous, quite entire ; capsules sessile ; 

 stigma dark purple. This is distinguished by the glaucous 

 appearance of its foliage, the purple hue of its corolla, and 



Jthe dark colour -pf its stigma. It is about two feet high, and 

 produces abundance of fine purple flowers in July and August, 

 which open like those of the seventh species during the day. 

 Cultivated in the same way as the preceding species. 



9. (Enothera Sinuata ; Scallop -leaved free Primrose. 

 Leaves tooth-sinuate ; capsules prismatic. Root annual ; 

 stem simple, round, a foot high, upright, -nodding at top, 

 when young hairy, when old smoothish ; tranches alternate. 

 It sleeps during the night, with the upper leaves hollowed. 

 Native of North America. 



10. (Enothera Fruticosa; Sfirubly Tree Primrose. Leaves 

 lanceolate, somewhat toothed ; capsules pedicelled, acute- 

 angled ; raceme peduncled. Stem three or four feet high, 

 round, hairy, pale red. This is a perennial, -but altogether 



81 :-' ' " '-' " ' 



herbaceous, at least with us, and therefore improperly named 

 Fruticosa. The flowers, which are large and showy, bright 

 yellow, though they open in the evening 1 , remain' expanded 

 during most of the ensuing- day. The flower-buds, germen, 

 and stalk, are enlivened by a richness of colour which con- 

 tributes to render this species one of the most ornamental 

 and desirable of the genus. Native of Virginia. It may be 

 increased by seeds, by parting the roots, and by cuttings, in 

 the open air. 



11. (Enothera Pumila; Dwarf Tree Primrose. Leaves 

 lanceolate, blunt, smooth, subpetioled ; stems prostrate, 

 (ascending ;) capsules acute-angled. This is distinguished 



! from all the species with yellow flowers, by the inferiority t>f 



its siz'e ; in its most luxuriant state, rarely exceeding a foot 



! in height, and commonly far more humble. It sends up 



I many flowering-stems, producing blossoms from April to 



I July, open in the morning as well as the evening. The 



! stalks are rather ascending than prostrate. Native of North 



America. It may be propagated by parting the roots, or by 



seeds. The best time for the former is the spring : but 



seeds should be sown in the autumn in pots, placed under a 



hot-bed frame in winter. In the spring the plants will 



appear : when fit t remove, plant a few in small pots, to be 



sheltered undfer a common frame in winter; plant the oioer* 



in a sheltered border, where they will endure the'cold of our 



Ordinary winters well, and in the following summer produce 



flowers and seeds in plenty. The seedling plants will be 



much stronger," and flower better,*than those from offsets. 



12. (Enothera Macrocarpa. Stem branchy; leaves lan- 

 ceolate, petiolate, distantly glandulous-denticulate, with the 

 margin and nerves of a silky white colour; petal sobcordated 

 with a point; capsules elliptical, four-winged, with very short 

 pedicels. Grows on the banks of the Mississippi, near St. 

 Loruis. " This species," Mr. Pursh remarks, " exceeds in 

 size and beauty of its flowers any other one known; they ar6 

 of a. bright yellow, very 'large, and open about five o'clock 

 in the evening. The calix is' covered with a very fine and 

 white silky down, and is sported with purple." It has not 

 yet been found any where else but near St. Louis, where 

 Mr. Thomas Nuttall gathered the ripe fruits of it; specimens 

 of which he sent to this country. to taiitia&Dp 0J1 



1.3. (Enothera Fraseri. Plant somewhat glabrous ; stem 

 on the lower part simple, but branchy above; leaves ovate, 

 petiolate, glandulose-denticulate ; racemes leafy ; capsule* 

 pedicellated, obovate, tetragonal. Native of South Carolina. 

 " This species," Mr. Pursh informs us, "approaches so near 

 to (Enothera Fruticosa, that it is difficult to define the dis- 

 tinction, though their other habits are so very different. 

 The present species' flowers a short time; the stems decay, 

 and form inttnediately a tuft of large radical leaves. (Eno- 

 thera Fruticosa flowers till late in autumn, and never shews 

 its radical leaves in that manner. The specific difference of 

 CEnothera Fruticosa from CEnothera Fraseri will be : CEno- 

 thera Fruticosa, Plant slightly pubescent ; stem branchy 

 from the base, divaricate; leaves sessile, lanceolate, snbden- 

 tate, acute; capsules pedicellate, oblong-clavate, angular." 

 14. CEnothera Scapigera. Plant without a stem ; leaves 

 lanceolate, inciso-dentate ; capsule oblong, sessile ; tube of 

 the calix very long; petals two-lobed, distant. Grows on 

 the bunks of the Missouri, where Mr. Lewis discovered it. 

 This singular species resembles the (Enothera Acaule of 

 Gavanilles. The flowers open in the evening, are white, 

 changing to red, and of an agreeable scent, 

 j 15. (Enothera Albicaulis. Plant very slightly pubescent; 

 i stem and nerves of the leaves white ; leaves pinnatifkl; seg- 

 I ments divaricated ; flowers subspicate, large, white ; gernaeo
