134 THE LADIES' FLOWER-GARDEN 
near a plant of Fraxinella, observed the gas exuding from it to take fire, and bum like a halo round the plant. 
This experiment can only, however, succeed in fine warm, dry weather. The plant when bruised, particularly 
the petioles, smells like lemon-peel, and has a rich balsamic fragrance. The root was formerly used in medicine. 
Both the • species and variety are natives of Germany and other parts of Europe, and were introduced before 
1596. They will grow in any common garden soil, and are increased by seeds or by division. 
2.— DICTAMNUS ANGUSTIFOLIUS, Swt. THE NARROW-LEAVED FRAXINELLA. 
Enqravings. — Swt. Brit. Flow. Gard. 2d ser. t. 93 ; and our 1 Specific Cuaractek. — Leaflets 4 — S pairs, alternate, ovate-lanceo- 
Jig* 1 in Plate 33. I l^te, acuminated, finely serrulated ; racemes long ; calyx nearly equal. 
Description, &c. — This species has numerous stems rising from the same root, which are not so stiff as 
those of the common species, and are consequently more graceful. The flowers are also larger and more 
delicately marked ; and the leaflets are much larger, serrulated with numerous short teeth, and dotted with a 
great number of little dots, which are smootli and glossy on the under side. The lower side is also covered with 
soft weak hairs, particularly on the nerves. The species is a native of Siberia, whence it was introduced in 
1821 ; and it requires the same culture as the common Fraxinella. It also agrees with that plant in its lemon- 
like smell, and in emitting a gas which will take fire by applying a light to it, and which will bum round the 
plant for a long time without injuring it. The root is medicinal. 
GENUS II. 
APLOPHYLLUM, Juss. THE ENTIRE-LEAVED RUE. 
Lin. Syst. DECANDRIA MONOGYNIA^ 
Generic Characteh Calyx five-parted. Stamens ten. Styles five, connected. Capsule fivo-Iohed, five-celled. (G. Don.) 
Description, &c. — The plants belonging to this genus differ from those included in the genus Ruta, in 
having entire leaves, instead of pinnate ones. There are several species, all natives of Europe and Asia, but 
only four or five of them have been introduced. The name Aplophyllum signifies simple-leaved. 
1.— APLOPHYLLUM SUAVEOLENS, G. Don. THE SWEET-SCENTED RUE. 
Specific Character. — Leaves entire, spatulately-lanceolate, glau- 
cous, smootlush ; calyxes a little fringed ; ovaries quite smooth ; 
petals ovate. 
Synonymes, — Ruta suaveolens, Dec. ; R. linifolia, Bieb. ; R. 1. 
grandiflora, Sims. 
Enqravings. — Bot. Mag. t. 2254 ; and oxa fig. 2 in Plate 33. 
Description, &c. — A very showy plant, with large clusters of yellow flowers, which have the scent of the 
cowslip. There is a variety, the flowers of which are lemon-scented. The species is a native of Asiatic Russia, 
and the variety is found in Greece. They are both quite hardy, and only require planting in the open garden. 
They are propagated by division of the root. They flower all the summer, from June to September. The 
species was introduced in 1800. 
OTHER SPECIES OF APLOPHYLLUM. 
A. PUBESCENS, G.Don; RUTA PUBESCENS, Willd.; R. PATAVINA, Pair. 
A native of Spain ; introduced in 1816. Flowers yellow.
