lines. Pod obovate, about 2 lines long, the valves winged only above the middle, 

 forming 2 rounded terminal lobes, a little more than ^ line long, with the stigma 

 sessile in the rather narrow sinus. Seeds exuding a viscid, clear mucilage in 

 great abundance. 



Hab.: Southern Queensland. 



4. Ii. ruderale (found in waste places), Linn.; DC. Prod. i. 205 ; Benth. Fl. 

 Austr. i. 86. An annual, biennial, or sometimes perennial, glabrous or with a 

 few minute scattered hairs, commencing to flower when very small, but growing 

 out to 1 or even 2ft., with hard stems and numerous divaricate, thin, wiry 

 branches. Radical leaves once or twice pinnatifid, with narrow-linear lobes, but 

 soon decaying ; stem-leaves linear or rarely almost oblong-cuneate, usually with 

 a few irregular teeth, especially towards the top, sometimes almost pinnatifid, the 

 uppermost often linear and entire. Flowers minute, without petals and with only 

 2 stamens. Fruiting racemes usually rather loose but rigid, 2 to Sin. long, with 

 slender stiff spreading pedicels of 2 or 3 lines, but sometimes the racemes remain 

 short and dense as when in flower. Pods ovate, 1 to near 1\ line long, minutely 

 2-lobed at the top, with a short style between the lobes. Seeds ovate, usually 

 exuding no mucus. — Reichb. Ic. Fl. Germ. ii. t. 10 ; Hook. f. Fl. Tasm. i. 25 ;

12. THLASPI, Linn. 



(Pods compressed.) 



Sepals erect, equal at the base. Petals obovate, equal. Pod short, ovate, 

 obovate, obcuneate or oblong, much compressed laterally, notched or rarely acute 

 at the top, the valves boat-shaped, keeled or winged, the septum narrow ; style 

 filiform or stigma sessile. Seeds 2 or rarely 3 or 4 in each cell, not winged ; 

 cotyledons accumbent. — Annual or perennial herbs, the radical leaves usually 

 spreading, entire or toothed, those of the stem often auricled at the base. Flowers 

 white, pink, or pale purple, rarely yellow. 



A considerable genus spread over the temperate and colder regions of the northern hemi- 

 sphere, with a very few S. American species, and none from S. Africa. 



1. T. cochlearinum (like a oochlearia), F. v. 21. PI. Vict. i. 51 ; Benth. Fl. 

 Amtr. i. 88. An erect, rigid, branching annual. Gin. to 1ft. high, slightly pubescent, 

 with a few short, mostly simple and reflexed hairs. Leaves lanceolate or linear- 

 oblong, entire or with 1 or 2 coarse teeth or lobes on each side, narrowed into a 

 petiole, the lower leaves about 2in. long, the upper ones few and smaller. 

 Flowers white, rather large. Sepals open, IJin. long. Petals much larger. 

 Fruiting racemes loose, about 2in. long, with half-spreading pedicels of 6 to 8 

 lines. Pod broadly oval, 4 to 5 lines long, obtuse at the top but not notched, 

 pubescent with short, rigid, reflexed hairs ; styles subulate, nearly 1 line long. 

 Valves keeled, but not distinctly winged. Seeds 2 to 4 in each cell, flat, 

 orbicular, emitting a clear, viscid mucus when soaked ; cotyledons accumbent.—
