1. N. rosulatum, Rook. /., n. sp. A very stout, erect, densely 
leafy, pyramidal, fleshy herb. Stem 0, or very short. Leaves very nu- 
merous and most densely crowded, imbricated, forming a rosette, spathulate, 
petioled, crenate, when young covered with weak cellular hairs, glabrous when 
old. Scape often thicker than the finger, a span high, bearing a profusion of 
white sweet-scented flowers. Pods 1 in. long, obovate, with a very short 
style. Seeds rather large, with a thin pitted testa ; radicle very long, often 
twice folded, first upwards, then downwards and backwards over the back of 
the cotyledons. 
Middle Island : alt. 3500 to 6500 ft. ; shingle beds on the Ribbon range, Mount Tor- 
lesse and Waimakeriri valley, Sinclair and Haas/ ; Wairau valley, Maling, Travers ; Lake 
Tennyson, Hough. A most singular plant. 
2. N. australe, Hook. f. — Thlaspi (?) australe, FI. N. Z. ii. 325. A 
small, perennial, densely tufted, much branched (rarely simple), glabrous 
plant, with short leafy branches, and very numerous white corymbose flowers ; 
roots slender, fusiform, descending deeply ; branches 1-2 in. long. Leaves 
cauline and radical, petiolate, J-l^ in. long, spathulate-oblong or linear- 
- spathulate, subacute, entire or crenate, coriaceous or fleshy, often recurved. 
Flowers white, scentless, in many-flowered corymbs, almost involucrate by 
the numerous cauline leaves, about J in. diam., on pedicels 1 in. long. 
Young pods obovate, refuse, with long stout styles ; valves winged. Seeds 
excessively numerous. 
Middle Island : top of Gordon’s Nob, Upper Wairau river, and elsewhere iu the Nelson 
Province, alt. 4-5000 ft., Munro, Sinclair, Travers, Haast. 
The most frequent naturalized Crucifera known to me in New Zealand are all common 
British weeds, except Alyssum maritimum, mentioned by A. Cunningham, but which is not 
fully naturalized. 
Capsella Bv.rsa-pastoris, Linn. (Shepherd’s-purse) . An annual, with spreading rosulate 
pinnatilobed radical leaves, simple or branched scapes, many small white flowers, an ob- 
cuneate or obcordate retuse flat pod, the valves not winged, and cells many-seeded. 
Senebiera pinnatifida, DC. A much branched, prostrate, glabrous, leafy annual, with 
bipinnatifid irregularly-cut leaves, short leaf-opposed racemes of very small, white flowers, 
succeeded by very small, didymous, wrinkled, indehiscent, 2-celled, 2-seeded pods. S. Coro- 
nopvs, Poir., with subacute, crested pods, is also found. 
Watercress, Nasturtium officinale, Linn., is a pest in the rivers about Canterbury, at- 
taining a size never seen in Europe, and is found also abundantly elsewhere. 
The Cabbage, Brassica oleracea, Linn., Turnip, B. campestris, Linn., Cress, Lepidium 
sativum, Linn., Charlock, B. Sinapistrum, Boiss., Horseradish, Cochlearia Armoracia, Linn., 
Radish, Baphanus sativus, and probably various others, occur as escapes from fields and gar- 
dens. — 
I have an indifferent specimen of a Cruciferous (?) plant, gathered by Haast, on terraces 
near Lake Okau, which 1 am unable to refer to any genus ; it is a slender branched herb, 
pubescent, with simple hairs ; small pinnate leaves ; leaflets in 1 to 2 pairs, rounded, entire 
or lobed ; and minute white flowers, that seem to be in an imperfect condition. 
Order IY. VIOLABXEiE.

gular. — Sepals 5, imbricate. Petals 5, imbricate. Stamens 5, hypogynous ;

panded upwards or provided with an appendage at the back, or both. Ovary
