Tho species is spread over Europe, North Ameifca, nbrthcrn Asia, the Himalayas, aud 

 ialand, and as an introduced weed in South Africa. lu Australia it is evidently indi- 

 genous The specimens all bebn^ to the var. stricta of most northern botanists [B.prrfcox, 

 nook. FJ. Bor. Am. i. 39, not of K. Br.), as usually defined, uith nearly erect stout pods 

 with a very short style. European specimens are often precisely similar.

3. ARABIS, Linn. 



(Turritis, Linn) 



Sepals rather "short, equal or the lateral ones saccate at tlie l)ase. Petals 

 entire, usually clawed. Pod sessile, elongated, slender, flattened ; valves flat, 

 AceJed,^ or with a midrib ; septum membranous ; stigma entire or 2-lobed, 

 oeeds in 1 or rarely 2 rows, flattened, often bordered or winged. — Annual or 

 perennial herbs, glabrous or tomentose w^ith spreading, branched, or stellate 

 5^airs. Eadical leaves usually spathulate, the stem ones sessile, often auricled. 

 r lowers w^hite or rarely purple, straw-coloured or pint. 



iue species are numerous in the temperate and colder regions of the northern hemisphere, 

 very few inhabiting the southern one; and none are peculiar to Australia. Cardamine 

 ylosa which in its undivided saunltatc leaves conies very near to Arahis, may be readily dia- 

 tuiguished by its reticulate pitted* seeds.

 ^tem erect, simple, rigid, 1 to 3 ft. high, usually glabrous except at the base, 

 nadical leaves petiolate, narrow-oblong, entire, or sinuately toothed, 2 to 4 



in. lon-r, usually pubescent or hirsute with stellate or brandling liairs ; steiu- 

 eaves erect, oblong-lanceolate, stera-clasping and usually auriculate at tlie 

 '^•'^se, and all except the lowest quite glabrous. Flowei;s rather small, white 

 or straw-coloured. Fruiting racemes long, rigid, with uuiuerous erect slender 

 pods, mostly 2 in. long or even more, and i to | liue broad. Seeds small, 

 wher as broad as the septum and in 1 ro«', or narrower and somewhat bise-
