This plant is united by Dr. Hooker with the European C praiensis, Linn., and it^ cer- 

 tainly is a very close representative of that species, but its lax, more branching stems, give it j 

 much more the habit of C. hiTsuia, In many respects indeed it seems almost to pass iuto 

 the latter species through its variety heterojjJii/Ha, and F, Mueller unites all these plants with 

 C, reseda/alia, Linn, and others, under the Linnsean name of C.parviflora. But long and re- 

 peated observation of the Eiu-opcan C. praiensis^ resedcpfolia, and hirsula, in a living state iu 

 various localities, prevents my admitting their union without much more convincing proofs i 

 and, if they are kept distinct, it appears necessary to maintam also the Australian C. tenui- 

 folia. It is, I believe, a perennial like C. prate usis, but that canuot always be ascertained 

 from dried specimens. 



C intermedia. Hook. Ic. PL t. 258, can scarcely be judged of from the single specimeu 

 preserved, but the st^le is certainly rather long and slender, and the habit and petals are 

 more those of C. tenuifolia than of C. Mrsida, 



6. C. hirsuta, Linn.; DC, Prod, i. 153. A much-branched decumbent 

 or tufted anuual, seldom above 6 in. high, either quite glabrous or sliglitly 

 hirsute with short spreading hairs. Leaves pinnately divided, the lower ones 

 with 1 ovate or rounded terminal segment and a few smaller petiolulate la- 

 teral oues, or sbmctiiiies reduced to the terminal one, the upper leaves few 

 with narrow lobes. Flowers veiy small, the petals narrow and erect or 

 scarcely spreading. Stamens often reduced to 4 (especially in European spe- 

 cimens). Fruiting racemes usually short and rather dense, the pedicels not 

 very spreading. Pods erect, slender, usually 7 to 9 lines long and scarcely 

 more than \ line broad, the stigma sessile or on a style not longer than the 

 breadth of the pod. Seeds smooth, as broad as the 'septum, and in a single 

 row as in all the preceding species. — "Reichb. Ic. Fl. Germ. ii. t. 26; Hook.

The species is very abundant in the temperate regions of the northern hemisphere, in the 

 hilly regions of the tropics, in New Zealand and the Pacific islands, and hi Antarctic Aiue- 

 rica. Always in the north a small-flowered annual, and sometimes glabrous. Many of the 

 Australian specimens are precisely like the glabrous European ones, but in others there are 

 signs of a procumbent slender rhizon^e, as is so frequent in the following variety or species. 

 I have preserved the name C. hirsula, in place of that of C. parvijfora adopted by F. Mueller, 

 because it is the one by which the plant is most universally known, botli being Liunican. 



Var. (?) helerophylla. Rhizome apparently in some instances perennial, though very slen- 

 der. Flowers rather larger, with more spreading almost obovate petals. Pod less slender, 

 and the whole plant approaching C tenuifolia in habit, but with an almost sessile stigin^, 

 as in C. hirsnta.—C. heterophjlla, Hook. Ic. PK t. 58.— Apparently a common Tasmanian
