pubescent or almost glabrous, suberect, 2-5in. high. Root stout 
and woody, often as thick as the finger, very long and tapering, 
much divided at the top. Leaves nearly all radical, numerous, 
crowded, spreading, 1-2 in. long, linear or linear-oblong in outline, 
deeply pinnatifid; segments many, small, short, entire or lobulate

A distinct species, at once separated from the two preceding by the more 
depressed habit, lax racemes, and ovate-rhomboid pods. The stout cylindrical 
root often descends for distances altogether out of proportion to the short stems. 
Mr. Enys on one occasion showed me specimens nearly 4 ft. in length. 
7. NOTOTHLASPI, Hook. i. 
Small fleshy simple or branched alpine herbs, glabrous or 
slightly hairy. Leaves all radical, or radical and cauline, spathulate, 
petiolate. Flowers rather large, white, densely crowded in a ter- 
minal raceme, or corymbose at the tips of the branches. Sepals 
erect, equal at the base. Petals spathulate. Pods rather large, 
obovate or oblong, much compressed, valves very broadly winged. 
Seeds numerous in each cell, reniform, attached by slender long 
funicles. Cctyledons incumbent ; radicle often very long. 
The genus is confined to the mountains of the South Island of New Zealand. 
Stem simple. Flowers densely crowded on a stout ter- 
minal peduncle or scape. Style very short .. .. 1. N. rosulatum.
