THE LADIES’ FLOWER-GARDEN 
GENUS IV. 
SABBATIA, Pursh. THE SABBATIA. 
Lin. Syst. PENTANDRIA MONOGYNIA. 
Generic Character. — Calyx five or twelve cleft. Corolla rotate ; , are twisted spirally. Capsule one-celled ; two-valved ; the margins 
five or twelve parted. Anthers rolling back after the discharge of the of the valves bearing the seeds, 
pollen. Style erect; divided into two long spreading stigmas, which I 
Description, &c. — Nearly all the species belonging to this genus are biennial plants, with angular stems 
and branches. The leaves are opposite and sessile, and the flowers are generally rose-coloured or white. They 
are all natives of North America. The genus is named in honour of two Italian botanists, called Sabbati. 
1.— SABBATIA CALYCOSA. Pursh. THE CALYCOSE SABBATIA. 
Synonyjies. — Chironia dichotoma, Walt. ; Chironia calycosa, Specific Character. — Stem diffuse, dichotomous ; leaves ovate- 
Michx. lanceolate ; calyx six-cleft, leafy, exceeding the corolla. 
Engravings. — Bot. Mag. t. 1600 ; and owfig. 2, in PI. 72. 
Description, &c. — This plant is a hardy biennial, propagated by seeds, and consequently easily lost. The 
flowers are very pretty, but the plant has a somewhat stiff appearance, from the angular disposition of the 
branches. The species is a native of North America, whence it was introduced in 1812 ; but, though quite 
hardy, it is now rarely to be seen in British gardens. 
OTHER SPECIES OF SABBATIA. 
lliere are several other species with pink or purple flowers ; but, as they are biennials, and of course easily 
lost, as they are propagated by seed, which only ripens in favourable seasons, they are rarely seen in British 
gardens. There is one species with white flowers, S. paniculata, wliich is said to be a perennial, but I have 
never seen it. 
CHAPTER XXXIII. 
SPIGELIACEiE. 
Character of the Order. — Flowers regular, of equal parts. 
Calyx free. Limb of corolla equal ; valvate in aestivation. Stamens 
four or five, rising from the corolla. Pollen trigonal ; the angles 
globular. Style inserted in the top of the ovarium ; articulated. 
Capsule in two divisions. Seeds small, with an immediate placenta- 
tion ; testa simple. Embryo small, straight, in fleshy copious albu- 
men. (G. Don.) 
Description, &c. — This order was formerly included in Gentianacem, but it differs from that order in the 
style being articulated, and in the immediate placentation of the seeds. Two of the genera contain plants 
which are cultivated in British gardens.

Description, &c. — The plants belonging to this genus have all fibrous roots and opposite connate leaves, 
which are quite entire. The flowers are in terminal secund spikes, which are somewhat revolute ; the flowers
