straight or curved, the stigma sessile or nearly so ; valves convex, with a slender 

 longitudinal nerve. Seeds numerous, small, oblong-ovoid, those which I have 

 soaked scarcely emitting any mucus. — Sisyuilrriiiiii trim-tuiit, F. v. M. in Trans. 

 Vict. Inst. i. 114 ; PI. Vict. i. 39. 

 Hab.: Downs of the southern parts of the colony. 



2. B. nasturtioides (Nasturtium-like), Benth. Fl. Austr. i. 74. A glabrous 

 annual, the central scape erect and leafless, the lateral branches decumbent at 

 the base and leafy, from 2 or Sin. to nearly 1ft. long. Leaves usually pinnately 

 divided into a few linear rather thick segments, the radical ones often 2in. long, 

 the others much smaller. Flowers yellow, rather small. Fruiting racemes 

 loose, 3 to 6in. long, with slender pedicels. Pod narrow, 4 to 7 lines long, 

 nearly straight and scarcely contracted at the base ; stigma sessile or nearly so ; 

 valves slightly convex, the longitudinal nerve very slender and sometimes quite 

 inconspicuous. Seeds small, ovate, emitting a considerable mucus when soaked.

3. B. eremigera (desert, place of growth), Benth. Fl. Austr. i. 74. Annual 

 and erect or branching and decumbent at the base, more or less hairy with short 

 simple hairs, from a few inches to l^ft. high. Leaves deeply and irregularly 

 pinnatifid, with few oblong-linear or linear, sometimes falcate lobes. Flowers 

 small, yellow. Fruiting racemes loose, 2 to 4in. long, with slender spreading 

 pedicels. Pods like those of B. iiasturtioides, mostly about Jin. long, slender, 

 straight or curved, not contracted at the base ; stigma sessile or nearly so ; 

 valves with a slender nerve. Seeds small, oblong-ovate, emitting mucus when 

 soaked. — Sisymbrium eremic/erum, F. v. M. Fragm. ii. 143.

4. B. cardaminoides (Cardamine-like), F. c M. Herb, (as a Sisymbrium) ; 

 Benth. Fl. Austr. i. 75. A slender or small annual like B. nasturtioides, but more 

 or less clothed with a minute stellate pubescence, sometimes scarcely visible 

 without a lens. Leaves pinnatifid, the radical ones with rather numerous small 

 ovate triangular or lanceolate lobes, the terminal ones confluent, the lower ones 

 becoming distinct segments along the petiole ; stem-leaves few and small, with 

 few short lobes. Flowers white (or pink ?), the sepals barely 1 line long. Petals 

 obovate, twice as long. Fruiting raceme loose and slender, 2 to 4in. long, with 

 slender spreading pedicels. Pod 4 to 6 lines long, scarcely 1 line broad, usually 

 curved, narrowed towards the base, glabrous or with a very minute stellate 

 tomentum ; valves very convex and keeled. Seeds small, ovate, emitting mucus 

 when soaked.

 PL Vict. i. 40, t. 2 ; Benth. Fl. Austr. i. 76. (" Woombun Woombun," St. 

 George, Wedd.) An annual, hoary with stellate pubescence, the central scape 

 short and erect, the lateral stems decumbent and leafy at the base, branching 

 and attaining 1ft. or more. Radical leaves petiolate, lyrate-pinnatifid, 1, 2, or 

 even 3in. long ; stem-leaves smaller, pinnatifid, or the upper ones toothed only. 

 Flowers pink or white. Calyx about 1 line, petals obovate, fully twice as long. 

 Fruiting racemes loose, 2 to 4in. long, with divaricate pedicels of 4 to 6 lines. 

 Pods not above Jin. long, turgid, curved, tapering at the top with a short slender 

 style, contracted at the base, hispid with simple or stellate hairs ; valves very 

 convex, with the midrib scarcely conspicuous. Seeds ovate, the mucus copious, —
