the calyx. 
FLOWER-GARDEN 
It is a long, straggling plant, with the flowers and leaves rather wide apart, and thus it forms a striking 
contrast to 7’. polyphyllum, the leaves and flowers of which are crowded together as closely as possible. 
It appears, from the works of Ruiz and Payon, that there are several other ornamental kinds of Tropzolum in 
South America which have not yet been introduced; and amongst others, one called JZ’. bicolorum, which is said 
to have the upper petals of a bright yellow, and the lower ones of a brilliant scarlet. 
The other genus included in the order Tropzxolacew, is called Magallana, but it contains only one species, a 
climbing annual plant with ternate leaves and yellow flowers, which has not yet been introduced.

RUTACEZ Juss. 
Essentiat Cuaracter.—Calyx with four or five divisions, toothed, 
cleft or parted. Petals equal in number to the divisions of the calyx, 
and alternating with them, usually distinct, and longer than the calyx, 
rarely connected into a monopetalous corolla. Stamens sometimes 
equal in number with the petals, and alternating with them; some- 
times double that number, with the alternate ones shortest. Fila- 
ments inserted in the gynophore, rarely beneath the hypogynous disk, 
and more rarely perigynous, or adhering to the bottom of the calyx, 
in consequence of the disk being joined with it; either naked or fur- 
nished with a scale at the base, free, very rarely connected at the base, 
or glued to the corolla, as in those with monopetalous flowers. Anthers 
two-celled, bursting lengthwise. 
number to the petals, and opposite them, rarely fewer, verticillate ; 
Ovary free, with the cells equal in 
sometimes fixed around the common axis; sometimes distinct to the 
base, sometimes joined together. Ovule fixed to the central placenta, 
usually two in each cell or carpel, rarely one, or from four to twenty. 
Styles equal in number to the cells or carpels, usually connected toge- 
ther in one, or only connected at the base or top, rarely wholly distinct. 
Stigma of as many lobes or furrows as there are styles in those that 
are joined. Fruit sometimes simple, having as many valves as there 
are styles, with a dissepiment in the middle of each valve, dehiscent, 
but more usually with an equal number of two-valved separable 
carpels, rarely indehiscent, composed of many drupes or carpels. Sar- 
cocarp thin, or more or less fleshy. Endocarp thin or woody, closely 
adhering to the sarcocarp, or separable from it into a two-valved elastic 
Seeds fewer than the ovule from abortion, with a mem- 
Albumen fleshy or 
cocculum. 
branous, or usually with a testaceous, covering. 
cartilaginously horny, rarely wanting. Embryo white or greenish, with 
a straight radicle pointing towards the top of the cells, rarely turned 
obliquely towards the hylum. Cotyledons of various forms. (@. Don.) 
Description, &c.—This is a very extensive order, but the greater part of the plants contained in it have a very 
strong and disagreeable odour, which prevents them from being so generally cultivated as they otherwise would be 
from their ornamental flowers. 
The common Rue, and other species in the same genus, are almost the only plants 
in the order which are perfectly hardy; but there are numerous greenhouse plants belonging to it, which are natives 
of the Cape of Good Hope and New Holland. Nearly all the plants contained in the order are shrubs. 
GENUS I. 
DIOSMA Berg. THE DIOSMA. 
Lin. Syst. PENTANDRIA MONOGYNIA. 
Generic Cuaracter.—Flowers regular ; petals five ; disk adhering 
to the calyx; fertile stamens five, perigynous, Ovaries one to five, 
joined in one. Seeds covered with a thin shining testa, usually 
crested at the apex. Albumen very thin or wanting. Embryo with 
a short radicle and ovate cotyledons, not rarely multiple, 
Description, &c.—All the plants contained in this genus are natives of the Cape of Good Hope, and they are 
all distinguished by a very strong fragrance, which appears to have been so agreeable to some of the older botanists 
that they named the genus from two Greek words signifying a divine smell. 
The Hottentot women at the Cape 
are also so partial to it that they make a kind of ointment from the bruised leaves, with which they anoint the body,
