40 CRUCIFERZ. (Lepidiwm. 
This is allied to L. oleracewm, but can be readily distinguished by the 
slender often prostrate habit, the long petioles of the radical leaves, their 
crenate margins, and by the notched pods. Myspecimens from the north ot the 
Manukau Harbour are suberect; Mr. Kirk’s are mostly prostrate. 
4. L. Kirkii, Petrie in Trans. N.Z. Inst. xxii. (1890) 439.— 
Small, prostrate, glabrous or nearly so. Stems many from the top 
of a short stout rootstock, prostrate, branched, flexuous, almost 
filiform, 2-4 in. fone Radical leaves entire, narrow-linear or 
linear-spathulate, 4-1 in. long, sheathing at the base, obtuse at the 
tip ; cauline similar but smaller. Racemes short, elongating in 
fruit. Flowers minute. Sepals ovate, concave. Petals narrow, 
slightly shorter than the sepals. Stamens 4. Pods on slender 
pedicels about their own length, ovate-orbicular, minutely notched 
at the tip; style short, exceeding the notch.—Kirk, Students’ Fl. 37.

An exceedingly well marked little plant, not closely allied to any other. 
5. L. flexicaule, 7. Kirk in Trans. N.Z. Inst. xiv. (1882) 380.— 
Perfectly glabrous, smooth and fleshy. Stems numerous, branched, 
flexuous, procumbent; branches ascending at the tips. Lower 
leaves 2-3in. long, petiolate, linear-oblong, pinnatifid; lobes 2-6 
pairs, entire or toothed at the tips. Cauline leaves smaller, sessile 
or shortly petiolate, linear-spathulate or cuneate, coarsely toothed 
towards the apex. Racemes 1-2in. long, lateral or terminal, 
leaf-opposed. Flowers small. Petals linear, obtuse. Stamens 2. 
Fruiting pedicels rather longer than the pod. Pod broadly ovate, 
slightly winged above, notched at the apex ; style not exceeding the 
notch.—Kirk, Students’ Fl. 35. L. incisum, Hook. f. Fl. Nov. Zel. 
i. 15; Handb. N.Z. Fl. 14 (not of Roth).

This appears to be an exceedingly local plant, and is fast becoming extinct. 
in the few habitats at present known. It is well characterized by the procumbent 
habit, lateral racemes, and diandrous flowers. 
6. L. tenuicaule, 7. Kirk in Trans. N.Z. Inst. xiv. (1882) 
381.—More or less clothed with minute soft whitish hairs, rarely 
glabrous. Stems numerous, slender, branched, procumbent or sub- 
erect, 6-12 in. long. Radical leaves numerous, thin, 1-4 in. long, 
linear-oblong, pinnate or pinnatifid; leaflets sometimes stalked, 
finely and sharply serrate or laciniate on the upper edge; teeth 
irregular, sometimes piliferous; petiole sheathing at the base. 
Cauline leaves usually few, sometimes absent, oblong- spathulate to- 
linear, sessile or shortly petiolate, entire or serrate. Flowers very 
numerous, minute, in long and slender terminal racemes. Petals 
wanting. Stamens 4. Pod very small, orbicular, shorter than the
