flower does not expand till evening, or in cloudy weather. This species is a native of Chili and Buenos Ayres, 
and it was introduced in 1832. Seeds may be purchased at any of the seed-shops ; and they should be raised on 
a slight hotbed in March, and planted out in May, when they will come into flower in July, and continue 
producing a succession of blossoms till October, or till killed by the frost. 
6.—NICOTIANA NOCTIFLORA, Hook. THE NIGHT-FLOWERING TOBACCO. 
Synonyme. — ? N. undulata, Vent. 
Engravings. —Bot. Mag. t. 2785 ; Swt. Brit. Flow. Gard. t. 262 ; 
and our fig. 3, in Plate 45. 
Specific Character. —Glandular and clammy, and beset with 
adpressed hairs. Leaves petiolate, oblong-lanceolate, acute, undulately 
curled. Tube of corolla cylindrical, much longer than the calyx ; 
segments of corolla equal, obcordately emarginate.—(G. Don.) 
Description, &c.— A very interesting species, growing about two feet high, with an erect, but somewhat 
slender, branching stem. The leaves are small, and much waved at the margin. The flowers, which are pro¬ 
duced in panicles, do not expand till evening; the corollas are white, and purple beneath. The flowers when 
expanded are very fragrant; but the plant is clothed with numerous short, clammy hairs, which have a very 
disagreeable smell when touched. The species is a native of the Andes, whence seeds of it were sent home by 
Dr. Gillies and Mr. Cruikshanks, in 1826. It succeeded quite well in the open border in the Glasgow Botanic 
Garden, where it flowered in the month of August. During the day, the plants made but little show; but 
towards evening, the flowers, which were during the day curiously folded up, slowly expanded, displaying by 
degrees their pure white surface, and yielding a delightful fragrance. Seeds may be procured in the principal 
seed-shops. 
7.—NICOTIANA PERSICA, Lindl. THE PERSIAN, OR SHIRAZ TOBACCO. 
Engravings. —Bot. Reg. 1592 ; and our fig. 7, in Plate 45. 
Specific Character. —Clothed with clammy down. Radical leaves 
oblong-spatulate ; cauliue ones sessile, half stem-clasping, acuminated, 
hardly repand. Calyx acutely 5-toothed. Corolla salver-shaped, with 
a long elavate tube, and ovate, obtuse, emarginate, rather unequal 
segments.—(G. Don.) 
Description, &c.— The flowers of this species are very handsome, being green on the outside, and white 
within ; they are produced in racemes, and are very sweet-scented at night. From the leaves is made the 
celebrated Shiraz tobacco, which is valued in proportion as the leaves of which it is composed are thick, tough, 
and uniformly yellow. To obtain this result, the plants are continually watered while they are growing; and 
when they have attained their full size, each plant is cut off close to the root, and stuck firmly into the ground. 
This is in September, when the heavy night-dews fall, and these soon change the leaves from green to the desired 
yellow. The leaves are then laid in heaps to heat, after which the stalks and midribs are thrown away, and 
the leaves are formed into cakes, which are pressed firmly together and packed in bags. When grown merely 
for ornament, the Shiraz tobacco is quite hardy, and only requires sowing in the open border. 
8.—NICOTIANA ACUMINATA, Sims. THE POINTED-LEAVED TOBACCO. 
Synonyme —Petunia acuminata, Graham. clothed with glandular down. Calycine segments narrow. Corolla 
Specific Character. —Downy. Leaves broad, lanceolate, acumi- with an elongated tube, and roundish obtuse segments.—(G. Don.) 
nated, undulated, on longish petioles. Panicles few-flowered. Calyx 
Description, &c.— The flowers are whitish, and not very handsome. The species is a native of Valparaiso, 
whence it was introduced in 1828, by Dr. Gillies. It requires no other care than sowing in the open border, 
but we do not know where seeds are to be procured.
