undershrubs, glabrous or hirsute with spreading hairs. Leaves simple or 
compound, digitate, or pinnate with the terminal leaflet sessile between the last 
pair. Stipules minute or none. Flowers yellow, orange-red, or bluish-purple, 
solitary in the axils of the upper leaves or forming terminal racemes. Bracts 
small ; bracteoles also small, usually below the middle of the pedicel. Ovary 
glabrous or villous. 
The genus is limited to Australia. It is closely allied to Gompholobium, with the same 
diversity of foliage, valvate calyx, etc.; differing chiefly in the ovules, always 2 only, with the 
funicles very long and thick, as in Gompholobium, but one always curved or folded upwards, the 
other downwards, not all downwards as in that genus. The style is also much thicker at the 
base. — Benth. 
Leaves pinnate. Racemes terminal. Plant glabrous. Racemes 1 to 3-flowered. 
Leaflets few, subulate 1. if. subulata. 
Leaflets numerous, very small, obovate or obcordate 2. B.foliolosa, 
1. B. subulata (awl-shaped), Benth. FI. Austr. ii. 50. An erect, glabrous 
shrub, of 1 to 2ft. with slender, rigid branches. Leaves pinnate, with a common 
petiole of 3 or 4 lines ; leaflets 5, 7 or rarely 9, linear-subulate, with revolute 
margins, mucronulate, f to fin. long. Flowers few, in very short, terminal, 
almost corymbose racemes, or often quite solitary ; pedicels usually longer than 
the calyx. Calyx glabrous, about 4 lines long. Petals nearly equal in length, 
slightly exceeding the calyx. Style more slender than in most Burtonias, yet 
somewhat dilated at the base. Pod compressed globular, scarcely exceeding the 
calyx . — Gompholobium subulatum, Benth. in Ann. Wien. Mus. ii. 72 ; G. steno- 
phyllum, F. v. M. Fragm. iii. 30. 
Hab.: Islands of the Gulf of Carpentaria, It. Br. (Benth. l.e.) 
2. 2. foliolosa (leaflets numerous), Benth. FI. Austr. ii. 50. An elegant 
little shrub, quite glabrous and somewhat glaucous, with slender terete branches. 
Leaves pinnate, the common petiole rarely above fin. long. Leaflets 11 to 21 or 
even more, obovate or obcordate, very obtuse, 1 to If line long. Flowers small, few 
together, in loose, terminal, almost corymbose racemes, the pedicels rather longer 
than the calyx. Calyx nearly 2 lines long, less deeply divided than in most other 
species, although the lobes are longer than the tube, the 2 upper ones more 
obtuse. Standard at least half as long again as the calyx ; wings and keel 
shorter. Ovary sessile, glabrous ; style slightly flattened towards the base. Pod 
not seen . — Gompholobium foliolosum, Benth. in Mitch. Trop. Austr. 848. 
Hab.: Sandy forests, Warrego River, Mitchell ; Dogwood Creek, Leichhardt. 
8. JACKSONIA, R. Br. 
(After G. Jackson.) 
(Piptomeris, Turcz.) 
Calyx deeply cleft, the tube usually very short, lobes valvate, the 2 upper ones 
broader, sometimes falcate, rarely connate. Petals shorter than the calyx or rarely 
exceeding it, nearly equal in length, the claws very short ; standard orbicular or 
reniform, usually emarginate ; wings oblong ; keel nearly straight, obtuse, 
broader than the wings. Stamens free. Ovary sessile or stipitate ; style subulate, 
incurved, with a minute terminal stigma; ovules 2 (except in J . piptomeris, of West 
Australia), attached by short funicles. Pod sessile or stipitate, ovate or oblong, flat 
or turgid. Seeds usually solitary, without any strophiole. — Shrubs or undershrubs, 
rigid and leafless, or rarely with a very few 1-foliolate leaves; branches rigid, 
terete, angular or winged, the branchlets often phyllodineous or leaf-like, flat or 
terete or angular, very much branched and spinescent. Leaves replaced by very 
minute scales at the nodes. Flowers yellow or with an admixture of purple,
