Crucifere.] FLORA OF NEW ZEALAND. 13 
Nar. Oro. III. CRUCIFERA. 
Gen. I. CARDAMINE, Linn. 
Siliqua linearis; valvis planis subenerviis, seepe elastice desilientibus. Semina ovata, immarginata ; 
cotyledonibus accumbentibus. 
Slender herbs, with small white flowers, and long narrow many-seeded pods, having sharp styles and faintly 
veined elastic valves. They taste strongly of cress, and one (C. hirsuta) makes a good salad. The genus is abundant 
in all temperate climates : many beautiful species inhabit Tasmania. (Name from kapdıa, the heart, and apao, to for- 
tify ; from its stomachic properties.)

Has. Most abundant throughout the islands, Forster, etc. Nat. name, “ Panapana,” Colenso. 
This common New Zealand species is abundant all over the world except in the hottest climates, and extremely 
variable everywhere; its distribution is dwelt upon in the “Flora Antarctica,” though I there left it doubtful whether 
the New Zealand plant was the same as C. hirsuta of Europe, etc.: I am now sure it is so, being unable to trace any 
distinction, however slight, between the common New Zealand and Scotch form. And I also now consider the Lord 
Auckland Group C. corymbosa to be a mere variety of the same. 
In its common form, this is a weak straggling plant 12 to 18 inches high, branching below, smooth or hairy, 
with unequally pinnate leaves; the lobes in two to eight pair, rounded or oblong, entire, sinuate or lobed, sessile or 
stalked, crowded or remote. Flowers white, seldom above 2 lines across. Pods slender, 3-13 inch long, tapering 
into a short style. Seeds rich yellow-brown.—The “English Botany’ figure (t. 492) represents exactly a very 
common New Zealand state, with oblong sinuate-dentate pinnules: the var. sylvatica of Europe is most common 
on the Middle Island: var. B, subcarnosa, of Fl. Antarctica, is found in humid places. Mr. Colenso has collected 
a very stunted form, an inch or so high, with rarely more than one lobe on the leaf and a one-flowered stem. On 
the whole, perhaps, the plant is best recognized by its taste of cress.

4. Cunn, Nat. name, * Matangoa,” Hügel, 
A smooth slender plant, two to three feet high, sparingly branched and leaved. Leaves two to four inches 
long, all, or the lower only, with petioles which sheath at the base ; upper sessile and hastate; all of them linear- 
oblong, waved or toothed at the margin, rarely more cut, and almost pinnatifid. Flowers white in some specimens, 
and in Banks’s collection of drawings and other dried specimens yellowish ; two to three lines broad. Pods numerous, 
Spreading, 1-14 inch long, half a line broad, pedicellate, straight, flat, rather suddenly tapering into a straight 
slender style, one to two lines long; valves veined. Seeds compressed, oblong, small, of a pale rich yellow-brown 
colour, deeply pitted. Very closely allied to Cardamine stylosa, DC. (Arabis gigantea, Hook. Yo. Plant. t. 259), 
and only distinguished by its smaller size, and much smaller seeds, which are of a different colour, and less deeply 
pitted. In Herb. Cunn. this plant is referred to Sinapis tenujfolia, and Baron Hiigel is given as authority for 
the native name.
