Stems Bimple or branched at the base, the lateral branches com- 

 monly short and erect or ascending. Leaves triangular or rhomboidal- 

 triangular or rhomboidal, rather thin, irregularly sinuate-serrate, more 

 i-arcly nearly entire. Glomerules of flowers in dense continuous 

 simple or compound spikes, ^vith very dense spicate or subcapitate 

 branches, with leaves at the base of each branch; spikes combined 

 -with rather dense narrow panicles, leafy up to the apex.

C botryoides, Bab. Man. Brit. Bot. od. vi. p. 287 (non 8m.). 

 C. rubrura, var. botryoides, Auct. Plur. 



Stem slender, decumbent, with elongate lateral branches. Leaves 

 rhomboidal or rhomboidal-triangular, subhastate, otherwise nearly 

 entire, or with a very few teeth on each side. Spikes very short, 

 simple, or with the branches short and spicate or subcapitate. 



On heaps of manure and in rich cultivated ground, and in waste 

 places where the soil has been recently disturbed. Rather common, 

 and generally distributed in England. Rare in Scotland, and probably 

 not native north of the Forth of Clyde. Very local and rare in 

 Ireland, where it is confined to the south "and east coast. Var, |3 by 

 the sides of pools at Loo, Cornwall ; near Thames Ditton, Surrey ; and 

 on sandy coasts at Deal, Kent ; and Hunstanton, Norfolk.

A very variable plant, but usually less branched, or, at least, with 

 the lateral branches shorter, than in C. botryoides. Leaves varying 

 from l to 5 inches lon^^, toothed or nearly entire, but thinner and less 

 brittle than in C. botryoides; the prmcipal difference, however, lies in 

 the inflorescence, the spikes in C. eu-rubrum being short, very compact,
