decumbent at the base, much branched, about a foot high, or in water 

 as much as 2 feet. Leaves often opposite, pinnate, with short, ovate,

 twice pinnate. Flowers almost sessile in the axils of the .upper leaves, 

 of a deep purple red. Calyx broad, with 2 broad, short, irregularly 

 cut or jagged lobes. Upper lip of the corolla with 2 minute teeth on 

 its inner edge just below the point, and 2 others below its middle. 

 Capsule oblique, the short point projecting beyond the calyx. 



In marshes, wet meadows, and watery ditches, in northern and 

 central Europe, and Russian Asia, from the Altai to the Arctic regions. 

 Generally spread over Britain, but not so common as the following

 teeth. Corolla with a distinct tube ; the upper lip compressed, entire 

 or with a small tooth or lobe on each side in front ; the lower lip spread- 

 ing, with 3 short lobes, and a more or less projecting palate closing the 

 mouth of the tube or nearly so. Capsule ovate, oblique, with from 1 to 

 4 oblong seeds. 



A small but distinct genus, confined to Europe and northern Asia. 



Flowers variegated with purple, in short leafy spikes. 

 Spikes closely imbricated, 4-sided. Floral leaves broadly cor- 

 date and finely toothed 1. M . eristatum. 



Spikes oblong, rather loose. Floral leaves ovate, acuminate, 



with long slender teeth ... . 2. M . arvense. 



Flowers yellow, in distant axillary pairs, all turned one way.

 Leaves lanceolate or linear and entire, or the upper ones toothed at
