CHENOPODIUM 
leones: — Beck in Reichenbach Icon, xxiv, t. 240, as C. album var. typicum-, t. 241, as C. album var. 
striatum ; t. 242, as C. album var. viride. 
Annual ; more or less mealy. Stem erect, grooved, more or less branched. Petioles about 
as long as the laminae. Laminae of the lower leaves subrhomboidal to sublanceolate, margin 
usually more or less toothed. Inflorescence more or less branched ; branches suberect to divari- 
cate. Perianth more or less mealy. Seeds all horizontal, not rugose, shining, about 2 mm. in 
diameter. 
As is well known, this is a very variable species ; and we do not claim that the following forms exhaust those 
which can be found in this country. We think there is much to be said for the position virtually adopted by Linnaeus 
(toe. cit .) that there are here really two species. On this supposition, the numerous forms which have been described 
by botanists might be regarded as consisting chiefly of hybrids and hybrid-segregates ; and we should welcome experi- 
ments with a view of testing this hypothesis. Syme ( Eng . Bot. viii, p. 15) states that one of the varieties of C. album 
invariably comes true from seed ; but the contrary has also been affirmed. The apparently contradictory results are each 
capable of being satisfactorily explained, if the above hypothesis be correct.

Shoot very mealy. Branches erect or suberect. Laminae subrhomboidal, more or less 
coarsely toothed. Inflorescences and partial inflorescences crowded. 
This is perhaps the commonest form of the species.

A small and perhaps a half-starved form of C. album var. spicatum. Laminae usually entire 
towards the base and toothed towards the apex. Inflorescence with shorter branches. 
Occurs sometimes with var. spicatum, but oftener on drier soils or at higher altitudes.

Taller and more luxuriant than var. spicatum, less mealy, greener. Laminae broader, more 
coarsely and irregularly toothed. Inflorescence laxer, more branched, more leafy ; branches usually 
divaricate, longer than the subtending leaves. Seeds rather larger. 
Very common in damp, rich, waste places in eastern England and doubtless elsewhere, but reliable records 
of this and of many other varieties of species are scanty.

Nearer var. virescens than var. spicatum in size, colour, and inflorescence. Laminae of the 
lower leaves broadly lanceolate, entire or subentire ; of the upper leaves lanceolate, entire. Seeds 
rather smaller (ro — V2 mm. in diameter) than in var. virescens.
