124 PENTANDRIA — DIGYNIA. [CJienopodium. 



leafy and leafless upon the same individual : and I can by no means 

 assent to the opinion that the C. acutifuUum is permanently distinct 

 from C. poli/!tpermurn, of vvliich Wallroth, an excellent observer, says 

 " variiit foliis ovatis, obtusis, emarginatis, rubro-marginatis, aciitis ; cymis 

 uphyllis et foliosis expansis." It is remarkable for its very numerous, 

 dark brown, shining seed (which is horizontal, Wils.), in part only en- 

 veloped by the perianth. 



*** Leaves plane, toothed, angled or lohed. 



5. C. Bonus Henricits, L. (^Mercury Goose-foot or good King 

 Henry); leaves triangular arrow-shaped (mostly) entire, spikes 

 compound terminal and axillary erect leafless. E. Bol. t. 1033. 



Waste places and way-sides ; frequent. Ft. Aug. %. — Stems I foot 

 high, striated. Leaves large, dark green, used, when boiled, instead of 

 spinach. C<dijx quite campanulate, 5 cleft half way down. Seed ver- 

 tical, coated with a true pellicle, besides the capsular integument, on 

 removing which the seed is smooth and shining. Wds. 



6. C. intermedium, Mert. et Kocli, (^upright Goose-foot); leaves 

 triangular toothed, spikes long erect approaching the stem sub- 

 simple nearly leafless, flowers scattered on the spikes. C. urbi- 

 cum, £". J^ot. t. 7 17 (iiot Linn, according to Borrer). 



Waste places, under walls, and about towns and villages. FI. Aug. 

 ©. — Stem erect, angular. Leaves large, truncate or subcuneate at the 

 base, of a light or suhglancous green, their margins deeply and irregu- 

 larly toothed. Flowers on the spikes, in rather small, but remote, clus- 

 ters ; spdies ver}' long and erect. Seeds or fruits (horizontal, rough, 

 coated very tightly with a papillose, fragile pellicle, Wils.), large in 

 comparison with those of the following species, " almost as big as rape- 

 seed." ( Curtis.) 



7. C. riihrum, L. (red Goose-foot); leaves triangular some- 

 Avliat rhomboid toothed and serrated, spikes erect compound 

 leafy, flowers crowded on the spikes. E. But. t. 1711. 



Dunghills and under walls. Fl. Aug. Sept. ©. — Of a darker green 

 tlian the last. Stems frequently reddish. Leaves always more or less 

 attenuated at the base, by no means truncate. Spikes very compound, 

 thick. — The salt (or alkali) contained in the juice of this plant crystal- 

 lizes upon the surface of the stem. Cal. in 3 deep segments. The 

 seeds are vertical, small, smooth, enveloped in a very loose bladdery 

 skin. Wils. 



8. C. botryodcs, Sm. (^many-spiked Goose-foot); " leaves trian- 

 gular shortly attenuated at the base scarcely toothed, spikes erect 

 compound leafy." E. Bot. t. 2247. 



At Yarmouth, Norfolk ; and cliffs by the sea at Lowestoft. Shore 

 at Soutli Shoebury. Fl Aug., Sept. © — Much resembling the last, 

 but smaller and less toothed in the margins of its leaves. This is quite 

 different from the C. Botri/s of Linn. 



9. C. micrdle, L. (nettle- leaved Goose-foot); leaves ovate ap- 

 proaching to rhomboid acute toothed shining, spikes much 

 branched cymose leafless. E. Bot. t. 1722. 



Waste places near towns and villages. Fl. Aug. ©. — Branches of 

 the spikes spreading. Flowers rather distant. Smell unpleasant.
