CHENOPODIACE^. 13 



pitchy black, closely invested by the pericarp, about the size of a 

 mignonette seed. Plant greyish green, more or less thickly sprinkled 

 with white meal, especially when young, intensely foetid ; stem con- 

 colorous. 



This is the only indigenous British Chenopodium which has any 

 perceptible odour, and, so far as I know, the only one of the genus 

 which is decidedly foetid, except the Russian C. foetidum.

Stem erect, more or less branched, the branches erect ascending. 

 Leaves rhombic or ovate- or lanceolate-rhombic, wedgeshaped at the 

 base, irregularly toothed; the upper ones narrower, attenuated at 

 each end. Flowers in moderately large glomerules, arranged in short 

 dense erect simple or slightly compound leafless spikes ; spikes 

 arranged in slender leafy terminal panicles: or the glomerules in 

 elongate lax compound spreading terminal and lateral spikes, leafy 

 towards the base, or in small cymes, sparingly leafy towards the 

 base; the spikes or cymes combined into a lax leafy panicle. Calyx 

 segments keeled on the back, covering the fruit, with narrow scarious 

 margins. Seeds all horizontal, rather small, shining, nearly smooth, 

 bluntly keeled all round. Stem, leaves, and calyx usually more or 

 less thickly clothed with white meal, which is most abundant when the 

 plant is young.

Stem often simple, or, if branched, with the branches suberect. 

 Leaves rhombic-triangular-ovate, dentate-serrate, more rarely sub- 

 hastate and otherwise entire, more or less white with meal, especially 

 beneath. Glomerules collected into short axillary and terminal erect 

 simple, or nearly simple, dense spikes, the axillary ones shorter than 

 the leaves from which they spring ; spikes combined into a very slender 

 acute panicle. Calyx thickly clothed with wliite meal.
