erect, simple, or slightly-branclied annual, 1 to 3 in. high, sprinkled with a 

 few stellate hairs. Radical leaves petiolate, ovate, entire, 2 to 3 lines long'; 

 stem-leaves lanceolate or oblong, often 5 to 6 lines long, the lowest narrowed 

 at the base, the others auricled and stcni-claspiug. Flowers small, white, the 

 petals longer than the sepals. Fruiting racemes loose, with slender divaricate 

 pedicels of 2 to 3 Hnes. Young pod obovate, veiy flat, wdth strongly keeled 

 valves and 3 or 4 seeds in each cell. — IlidcJunsia Tasmanica, Hook. Ic. PI.

The habit of this little plant is quite that of the European species of Thiaspi, in wlijeh 

 enus Dr. Hooker had at first placed it. We have since thought it might belong to the New 

 lealaud genus Notothiaspi, characterized by numerous seeds and incumbent cotyledons, a 



poiiit which cannot be determined till more mature seeds shall have been examined. The 



habit is against the association. 



2. T. cochlearinum, ¥. MuelL PL Vict, i. 51. An erect, rigid, 

 branching annnal, 6 in. to 1 ft. high, slightly pubescent, with a few short, 

 mostly simple and reflexed hairs. Leaves lanceolate or linear-oblong, entne 

 or with 1 or 2 coarse teeth or lobes on each side, narrowed into a petiole, the 

 lower leaves about 2 in. long, the npper ones few and smaller. Flowers 

 white, rather large. Sepals open, 1 J in. long. Petals much larger. Frmt- 

 ing racemes loose, about 2 in. 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, or- 

 bicular, emitting a clear, viscid mucus when soaked ; cotyledons accuuibent.

3. T. oclirantliuin, -F. MuelL mss. From the very few specimens this 

 appears to be a smaller plant than T. cochltarinnm, which it approaches very 

 nearly, with the same apprcssed hairs, either reflexed or attached by the 

 centre, and a similar though smaller foliage, but the flowers are yellow, the 

 fruiting pedicels much shorter, and the pods veiy broadly oval or almost or- 

 bicular, about 3 lines long.

 linear-lanceolate, coarsely toothed and on long petioles, but the few oa t'le 

 specimens are in a very bad state. Fruiting racemes 2 to 4 in. long, ^y^l" 

 spreading pedicels mostly of about 2 lines. Pods obovate-oblong, 4 lines 

 long and 2 broad, obtuse or almost notched, with a very short style, acute at 

 the base, sprinkled with stellate hairs ; the valves acutely keeled but scarcely 

 winged. Seeds 2 to 4 hi each cell, ovate, compressed, emitting a clear viscid 

 mucus when soaked ; cotyledons accumbent,
