Waste places, usually in rich soil, chiefly in the E. and S. of England, York to 

 Kent and Sussex ; Ireland rare ; Channel Islands ; fl. Aug-Sept. — Yery 

 near C. al'bum, but more flaccid, flowers later, with more oblong-hastate 

 leaves whose basal lobes spread more, and above which the leaf is often 

 contracted, inflorescence almost leafless, seeds smaller. — Distrib. Europe. 



5. C. ur'bicum, L. ; erect, sparingly mealy, leaves triangular acute 

 deeply toothed or subentire, spikes erect leafless simple axillary or in a

Waste places, indigenous from York southd. only ; Ireland ; fl. Sept.- 

 Oct. — Stem 6-36 in., stout, sparingly branched. Leaves 1-3 in., often af 

 broad as long ; petiole usually shorter, winged above ; lateral nerves spreading. 

 Spike f-2 in., rather dense-fld. — Distrib. Europe, Canaries, N. and W. Asia 

 introd. in N. America. 



C ur'bicum proper (C. deltoi'deum, Lamk.) ; leaves deltoid shortly toothed or 

 subentire, spikes erect longer than the leaves, panicle leafless above. — Yar. 

 C. intermedium, Mert. and Koch ; leaves rhombic-triangular deeply sinuate- 

 toothed, spikes shorter than the leaves, panicle leafy almost to the top. 



6. C. hy'bridum, L. ; erect, almost glabrous, leaves large long-acumi- 

 nate with 2-4 broad lobes on each side, spikes in lax axillary almost 

 leafless corymbs, sepals obtusely keeled not covering the utricle broadly 

 scarious, seed large opaque coarsely pitted not keeled. 



Fields and waste places, from Lancashire and Norfolk to Somerset and Kent, 

 local ; (a native ? Wats.) ; fl. Aug -Sept. — Odour heavy. Stem 1-3 ft., stout,

7. C. mura'le, L. ; nearly glabrous, leaves bright green rhombic- or 

 deltoid-ovate acute entire at the cuneate base, upper narrower serrate, 

 spikes short densely panicled, sepals slightly keeled almost covering the

Waste places, near houses, from Northumbd. southd., rare in England ; Ireland, 

 very rare ; Channel Islands; fl. Aug.-Sept. — Rather foetid. Stem 6-18 in., 

 erect or ascending ; branches decumbent. Leaves f-3 in. broad, rather 

 shining, teeth sharp ; petiole shorter than the blade. Spikes §-£ in. Seed
