XLIII. LEGUMINOSvE.

3 lines long, pubescent, the lobes lanceolate. Standard very broad, shortly 
exceeding the calyx, slightly streaked ; wings and keel nearly as long. Ovary 
nearly sessile, with about 20 ovules. Pod linear, pubescent, often exceeding 
lin . — ChorizCma LeichharcLtii , F. v. M. Fragm. iv. 20.

2. I. parviflora (small-flowered), Benth. in Ann. Wien. Mus. ii. 71, and 
FI. Austr. ii. 40. Very near I. Jilicaulis, and Mr. Bentham says perhaps a 
variety of that species. Stems slender, decumbent, branched, pubescent. Leaves 
of a single leaflet, articulate on a rather short petiole. Flowers smaller than in 
I. jilicaulis in all the specimens seen, on short axillary or leaf opposed pedicels. 
Calyx pubescent, about 2 lines long. Petals of I. jilicaulis, but smaller. Pod 
linear, pubescent, about lin. long. — Benth. l.c. 
Hab.: Islands of the Gulf of Carpentaria, R. Br. (Benth.) 
6. GOMPHOLOBIUM, Sm. 
(From gomphos a wedge, and lobos a pod.) 
Calyx deeply cleft, the tube very short, the lobes lanceolate, valvate, the 2 upper 
ones sometimes more falcate or slightly cohering, but not connate. Petals very 
shortly clawed. Standard orbicular or reniform, longer than the lower petals ; 
wings oblong, more or less falcate ; keel usually broader than the wings, obtuse ; 
Stamens free. Ovary usually shortly stipitate or nearly sessile ; style incurved, 
filiform or slightly thickened from the middle upwards ; ovules several, usually 8 or 
more, rarely 4 or 6, the funicles long and thick, all curved or folded downwards. Pod 
broadly ovoid or nearly globular, usually oblique, inflated. Seeds small, without 
any strophiole. — Shrubs or rarely undershrubs, glabrous pubescent or hirsute 
with spreading hairs. Leaves simple or more frequently compound, the leaflets 
usually narrow, digitate or pinnate with the terminal leaflet sessile between the 
last pair. Stipules small, lanceolate or subulate, or none. Flowers yellow or 
red, terminal or rarely in the upper axils, solitary or 2 or 3 together or in short 
racemes. Bracts and bracteoles small, sometimes minute or none. Ovary 
glabrous in all except G. Baxteri (a West Australia species), where the style is also 
exceptionally thickened at the base. 
The genus is limited to Australia. It is readily distinguished from all except Burtonia by the 
calyx and pod, and is separated from that genus by the more numerous ovules, with the regularly- 
packed funicles all turned downwards. The ovules in both genera are usually scarcely larger 
than the breadth of the funicle. — Benth. 
Pedicels longer than the calyx, solitary or 2 or 3 together in a very loose 
raceme. Plant glabrous. Leaflets 3, digitate, 1 to 2in. long, the common 
petiole usually very short. Standard above lin. diameter. Keel densely 
fringed 1. G. latifolium. 
Pedicels very short or not longer than the calyx, solitary or 2 or 3 together in 
dense leafy corymbs or heads. Leaflets 3, digitate, above Jin. long, 
usually flat or recurved. Plant quite glabrous. Calyx 4 or 5 lines. 
Standard 6 or 7 lines long 2. G. virgatum. 
Leaves pinnate. Leaflets more than 3. 
Shrubs, usually diffuse, not viscid. Calyx glabrous. 
Leaflets cuneate. Common petiole elongated 3. G. nitidum. 
Leaflets narrow-linear. Common petiple elongated 4. G. pinnatum. 
(The pinnate-leaved species with only 2 ovules to the ovary are now transferred to 
Burtonia. — Benth.) 
1. G. latifolium (broad-leaved), Sin. in Ann. Bat. i. 505, and ii. 519, and 
in Trans. Linn. Soc. ix. 249, not of Labill.', Benth. FI. Austr. ii. 42. A glabrous 
shrub, with erect virgate branches. Leaflets 3, on a very short common petiole, 
linear, linear-lanceolate or linear-cuneate, acute or truncate and mucronate, 1 to 
2in. long, the margins flat or slightly recurved, the veins fine and almost longi-
