compressed, red-brown.—Kirk, Students' Fl. 28. Arabis fastigiata, Hook. f. Fl. Nov. Zel. ii. 324. Pachycladon elongata, Buch. in Trans. N.Z. Inst. xix. (1887) 216. Notothlaspi Hookeri, Buch. l.c. xx. (1888) 255, t. 13.
South Island: Nelson—Wairau Gorge, Sinclair! T. F. C. Marlborough—Macrae's Run, Monro; Upper Awatere, Kirk! Canterbury—River-bed of the Macaulay, Haast. Otago—Mountains near Lakes Wanaka and Ohau, Buchanan! Altitudinal range 2500–5000 ft.
This and the two following species differ from Cardamine in the seeds being 2-seriate.
6. C. latesiliqua, Cheesem. in Trans. N.Z. Inst. xv. (1883) 298.—Rootstock stout, spongy, as thick as the finger, often branched at the top, each division furnished with a rosette of densely crowded radical leaves. Flowering-stems few or many, erect or spreading, branched, leafy at the base, 6–24 in. high. Radical leaves 3–6 in. long, ⅓–⅔ in. broad, narrow linear-spathulate to obovate-spathulate, gradually narrowed to the base, coarsely serrate above, thick and coriaceous, more or less villous, especially on the margins. Upper cauline leaves smaller, lanceolate, nearly entire. Flowers rather large, white, very numerous. Petals nearly ½ in. long, spathulate, on long claws. Pods erect or suberect, usually curved, somewhat turgid, 1½–2½ in. long, 16–14 in. broad. Seeds numerous, compressed, reddish-brown.—Kirk, Students' Fl. 28.
South Island: Nelson—Mount Arthur, T. F. C, Bryant! Gibbs! Mount Owen and the Raglan Mountains, T. F. C. Altitudinal range 3000–5500 ft. December–January.
A handsome plant, with much of the habit and general appearance of C. fastigiata, but easily distinguished by the villous leaves, larger flowers, and much broader pods, which have a turgid appearance very unusual in the genus.
7. C. Enysii, Cheesem. MSS.—Short, stout, 2–4 in. high. Rootstock thick and fleshy, perpendicular, ½ in. diam., bearing at its summit numerous radical leaves, and a short flowering-stem which is much branched from the base, and forms a rounded or pyramidal head 2–5 in. diam. Leaves ½–1½ in. long, ⅓–½ in. broad, oblong-spathulate, obtuse or subacute, narrowed into a broad flat petiole, rather thin, sharply serrate, sometimes almost pinnatifid, more or less densely clothed on both surfaces with stellate pubescence. Cauline leaves linear or linear-spathulate, toothed towards the tip. Flowers numerous, corymbose, white. Pedicels slender, spreading, ¼–⅓ in. long. Petals spathulate, with long claws. Pods (immature) narrow-linear, flat, about 1 in. long. Seeds numerous, in 2 series.—Kirk, Students' Fl. 28.
South Island: Canterbury—Mountains at the head of the Broken River, alt. 6500 ft., J. D. Enys and T. F. C; Craigieburn Mountains, alt. 6000ft., Cockayne! Otago—Mount Ida, 5000 ft., Petrie!
A very remarkable plant, easily separated from the two preceding species by the smaller size, depressed habit, and stellate pubescence. The seeds are too immature in all my specimens to allow me to determine the position of the radicle, and it is possible that the plant may not belong to Cardamine.
