the stem, the uj)pev leaves sometimes undivided and hastate. Flowers very 

 small, yellow. Pods about ^ in. long, thick at the base, tapering to the 

 point, more or less hairy, almost sessile, and closely pressed against the axis 

 in long, slender, stiff racemes. — Reichb. Ic. PI. Germ. ii. t. 72. 



S. Australia, ALunJant on roadsides and waste places about xidelaide, F, Mueller 

 and others. 



^^- Australia, I)rumwo7id, In both colonies, introduced from Europe. The species 

 IS somewhat auouialous in the genus, the valves of the pod having a somewhat prominent 

 midrib, and the seeds in the lower broader part sliowing two almost distinct rows. 



8. BLENNODIA, E. Br. 



Sepals short, open, eqnal at the base or slightly saccate. Petals obovate, 

 or short and narrow. Pod linear or linear-oblong (short in a variety of B, 

 trkeda), terete or 4-angled, the valves very convex, without nerves or with a 

 prominent midrib ; septnm membranous or almost spongy ; stigma capitate, 

 sessile or on a very short style. Seeds oblong or ovoid, more or less distinctly 

 2-rowed, not bordered, when soaked usually emitting a copious tibrous mucus; 

 fiinicles free, filifornu Cotyledons iucumbent,— Herbs or low undershrubs, 

 glabrous or hoary-tomentose with simple or stellate hairs. Leaves entire or 

 pinnatifid. Flowers white, yellow, or pink, the racemes without bracts. 



A genus limited to extratroplcal or subtropical Australia, differing from Slvjmhrium, to 

 ^hich some species have been referred, in the seeds never so completely overlappmg each 

 other as to form a single row, and generally iu the copious mucus of the seeds, which is 

 however not constant in all the species. From Capsella it differs in the lon-cr pod, aud m 

 the dissepiment broader iu proportion to the transverse diameter of the pod.
