Kirx.—On the New Zealand Lepidia. 881 
This species is allied to L. sisymbrioides, from which it is distinguished 
by the naked stems, apetalous flowers, straight pedicels, and narrowly- 
winged pods. 
In old specimens the root is four feet long, and fully one inch in diameter; 
much divided near the apex, so that the numerous heads form a compact 
hemispherical mass of leaves 6’-12" across. The stems of the § plant 
are more leafy at the base than the female, and produce fewer flowers. It 
is evidently the supposed Lepidium incisum stated in the Handbook to have 
been collected by Haast on ‘ limestone rocks in the subalpine region of the 
Waimakariri.’ 
5. Lepidium tenuicaule, n.s. 
Leaves all radical, and with the stems more or less clothed with short 
whitish hairs: pinnate or pinnatifid, 1'-8" long: segments laciniate and 
sharply serrate on the upper margin ; teeth linear, acute, piliferous. Stems 
Very numerous, prostrate, 6’-12" long, extremely slender, flexuous, simple or 
branched, leafless, or with two or three minute entire leaves on the lower 
part. Flowers excessively numerous, perfect, on short, slender pedicels, 
stamens 4, pod small, shorter than the peduncle, orbicular, not winged, 
style minute. 
Hab,— South Island: Cape Wiaabee We 
This species differs from all other New Zealand forms in the vhetinaky 
habit and innumerable flowers, and the orbicular pods separate it from all 
except L. australe; the aye in the fully-formed fruit is reduced to a mere 
point, 
It was originally discovered by Mr. D. Petrie, and is produced in abun- 
dance after every disturbance of the silt which covers the cape, but decreases 
in quantity as the surface becomes consolidated. 
6. Lepidium australe, n.s. 
An erect, much-branched, leafy species, 10’-15" high. Radical leaves 
3'-6" long, on rather long petioles, linear-oblong, narrowed below, pinnate; 
leaflets shortly petioled, incised and toothed on the upper margin, or rarely 
entire. Cauline leaves smaller, pinnatifid or entire serrate. Racemes 
terminal, spreading, flowers perfect, shortly pedicellate. Pods orbicular 
or ovate-orbicular, minutely emarginate, style minute.

Allied to L. tenuicaule, from which it differs widely in habit, in the 
Tacemes being leafy at the base and in the somewhat wider pod, which is
