GENUS XL. 
HARDENBEEGIA Benth. THE HARDENBERGIA. 
115 
Generic Character. — Calyx campanulate, very slightly five-cleft, 
somewhat bilabiate. Standard orbicular, cmarginate, without any 
appendages at the base, and with a very short claw. Wings and keel 
extremely small. Keel curved and blunt at the extremity. Stamens 
Un. Sysf. DIADELPHIA DECANDRIA. 
distinctly diadelphous, the free stamen straight and not articulated. 
Ovary with several ovules. Style short. Stigma capitate, usually with 
a short tuft of hair. Legume linear, flattened, almost divided into 
several cells by a cellular substance. Seeds with a strophiola. 
Description, &c. — This genus consists of six species of climbers, -which have been separated from the old 
genus Kennedya, and which are all natives of extra-tropical Australia. They are all remarkable for their flowers, 
which are small and of a pinldsh purple, and which are produced in upright spike-like racemes, each raceme 
containing many flowers. The name of Hardenbergia was given to the genus in honour of the Countess 
Hardenberg, sister of Baron Hiigel. 
1.— HARDENBERGIA MONOPHYLLA Benth. THE SINGLE-LEAVED HARDENBERGIA. 
SvNONYMES. — Kennedya monopbylla Vent . ; Glycine bimaculata 
Cv/rt . ; G. virens Sol. 
Engravings. — Bot. Mag.,t. 263 ; Bot. Reg., t. 1336; The Botanist, 
t. 84. 
Specific Character. — Leaves having only one leaflet ; leaflet 
lanceolate or oblong, subcordate at the base. Peduncle much longer 
than the raceme. 
Description, &c. — There are two varieties of this species, one of which has a longer raceme and paler flowers 
than the other. Both are pretty little plants, easily distinguished from the other species of the genus by the 
leaves, which are simple, or, rather, according to the language of botanists, consist of a single leaflet, which is heart- 
shaped at the stalk. The flowers are very small, and either of a very dark bluish-purple, in which case they are 
produced m a short close raceme, or of a very pale pinkish-lilac, in which case they are produced in a loose, very 
long raceme. The species was introduced in 1790, and as it is very easily cultivated, it has been common in green- 
houses ever since. 
I OTHER SPECIES OF HARDENBERGIA. 
I H. COMPTONIANA Benth. 
I This species was originally called Ghjcme Comptoniana in honom’ of the Marchioness of Northampton. It was 
j afterwards removed to the genus Kennedya, and it is now included in Hardenbergia. It is a very pretty plant, 
j with a long raceme of small dai’k pm'ple flowers, and it is one of the most common plants in greenhouses, as it is of 
I 
i remarkably easy culture. The plant is a native of the neighbourhood of Port Jackson, in New Holland, and it 
I 
i was introduced in 1803. It has a twining habit, and when planted in the free gi’ound of a conservatory, it will 
grow to a very considerable height. 
H. OVATA Benth. 
This species very closely resembles H. monophylla, the principal difference being in the size of the solitary 
I leaflets, which are large and broad in this species. The flowers are also somewhat larger, but they are in smaller 
racemes, and altogether the plant is not particularly ornamental. 
H. CORDATA Benth. 
This plant, hke the last, closely resembles H. monophylla in its solitary leaflets ; but they are still larger than 
in the last species. They look, indeed, like broad, cordate, simple leaves. The flowers are produced in rather 
larger racemes, and are very ornamental.
