 mostly pinnate ; leaflets petiolulate. Cauline leaves numerous, pinnatifid, toothed, lobed or entire. 

 Pods orbicular or orbicular-ovate. Cape Whanbrow, T.K. 



This species is readily distinguished by its prostrate stems and minute orbicular pods. The 

 Dog Island specimens have almost fleshy glabrous leaves and suberect stems, but present no other 

 difierenoe. In the original description the pods were erroneously described as wingless. 



7. NOTOTHLASPI, Hook. f. 



Sepals erect, equal. Stamens 6. Pods excessively compressed and broadly 

 winged ; cells many-seeded. Funicle slender. Radicle incumbent, sometimes 

 very long. Annual or biennial herbs, with rosulate fleshy radical leaves. 



The genus is restricted to the SOUTH Island of New Zealand.

1. N. rosulatum, Hook. /., Handbk. 15. Erect, 3in.-10in. high, stem- 

 less or nearly so. Leaves all radical, fleshy, imbricated, forming a densely- 

 crowded rosette, petioled, spathulate or spathulate-oblong, crenate or rarely den- 

 tate, subacute, clothed with caducous stellate cellular hairs when young, glabrate 

 or glabrous when old. Scape iin.— fin. in diameter. Flowers densely crowded, 

 forming a conical or pyramidal raceme, fragrant. Sepals elliptical. Petals 

 obovate- spathulate. Ovary obovate, sessile. Pod ^in.— lin. long, obovate, 

 broadly winged, deeply emarginate ; style very much shorter than the notch ; 

 stigma broadly 2-lobed. Seeds oo, reniform ; testa pitted. Radicle long and 

 slender, folded first upwards, then downwards and backwards over the back of 

 the cotyledons. — N. notabilis, Buch. in Trans. N.Z.I, xiv. (1881) 344, t. 25.

One of the most remarkable plants known ; now becoming very rare owing to the ravages of 

 sheep. The leaves are often ciliated, with flat ribbon-like hairs, and before flowering form a dense 

 imbricating cushion 2in.-3in. high. The flowers have the fragrance of orange-blossoms. 



3. N. australe, Hook. /., Handbk. 15. Usually much branched from 



the base; branches lin.— 3in. long. Radical leaves forming a rosette, glabrous 



or with few cellular hairs, petiolate, linear-lanceolate or spathulate or oblong- 



spathulate, fleshy, crenate or rarely entire. Flowers numei'ous, corymbose, 



smaller than in the preceding species. Ovary oblong, usually with a few short 



hairs ; style stout, long. Fruiting pedicels iin.-lin. long. Pod much shorter, 



broadly elliptic, winged, scarcely retuse ; style one-third as long as the pod. 



Seeds numerous ; testa pitted. Radicle slender. — Thlasp) australe, Hook, f.,
