not so much crowded into a spike. Fl. axillary, solitary, oppo- 

 site, turned in pairs to one side. Cal. bell-shaped, with teeth 

 of its own length. Cor. pale at the base ; deep yellow towards 

 the summit, with a purple spot at each side of the mouth, which 

 is closed, not gaping, the lower lip prominent and straight, not 

 deflexed; palate elevated, orange-coloured. Caps, with a curved 

 point. Seeds 2 in each cell. 

 Cows are reported to be fond of this plant, and Linnaeus says the 

 best and yellowest butter is made where it abounds. /3 is given 

 but as a variety by Dillenius himself, and Vaillant was of the 

 same opinion. It seems to differ only in having paler flowers. 



4. M. sylvaticum. Wood Cow-wheat.

This agrees with the last in general habit, but is rather smaller, 

 especially the Jlowers. The stem is roughish. Leaves broader, 

 less apt to turn black in drying, all of them generally quite en- 

 tire, as well as equidistant, each pair from the bottom of the 

 branch u])wards, being accompanied by a pair of Jlowers, less 

 decidedly turned to one side, and by no means crowded into 

 spikes. Segments of the cali/x lanceolate, longer than the tube. 

 Cor. half the size of the preceding, deep yellow, with some 

 orange or red spots about the mouth, which is open, not closed ; 

 the lower lip pointing downwards ; upper elevated. Capsule 

 less pointed ; the valves reticulated with prominent veins. Seeds 

 sometimes solitary in each cell, but mostly in pairs.
